Investments in debt and equity securities which are categorized neither as held-to-maturity nor trading and which are intended to be sold or mature more than one year from the balance sheet date or operating cycle, if longer. Such securities are reported at fair value; unrealized gains (losses) related to Available-for-sale Securities are excluded from earnings and reported in a separate component of shareholders' equity (other comprehensive income), unless the Available-for-sale security is designated as a hedge or is determined to have had an other than temporary decline in fair value below its amortized cost basis. All or a portion of the unrealized holding gain (loss) of an Available-for-sale security that is designated as being hedged in a fair value hedge is recognized in earnings during the period of the hedge, as are other than temporary declines in fair value below the cost basis for investments in equity securities and debt securities that an entity intends to sell or it is more likely than not that it will be required to sell before the recovery of its amortized cost basis. Other than temporary declines in fair value below the cost basis for debt securities categorized as Available-for-sale that an entity does not intend to sell and for which it is not more likely than not that the entity will be required to sell before the recovery of its amortized cost basis are bifurcated into credit losses and losses related to all other factors.

Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation).

A noncurrent taxable temporary difference is a difference between the tax basis and the carrying amount of a noncurrent asset or liability in the financial statements prepared in accordance with generally accepted accounting principles. In a classified statement of financial position, an enterprise separates deferred tax liabilities and assets into a current amount and a noncurrent amount.

- Definition
Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation).

| Investment In Unconsolidated Affiliate [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Investment In Unconsolidated Affiliate | Investment in Unconsolidated Affiliate The Company has an investment in the general partnership LSV Asset Management (LSV). LSV is a registered investment advisor that provides investment advisory services to institutions, including pension plans and investment companies. LSV is currently an investment sub-advisor for a small number of SEI-sponsored mutual funds. The Company accounts for its interest in LSV using the equity method because of its less than 50 percent ownership. The Company’s interest in the net assets of LSV is reflected in Investment in unconsolidated affiliate on the accompanying Consolidated Balance Sheets and its interest in the earnings of LSV is reflected in Equity in earnings of unconsolidated affiliate on the accompanying Consolidated Statements of Operations. As of December 31, 2011, the Company's total partnership interest in LSV was approximately 41.2 percent. In March 2009, certain partners (the Contributing partners) of LSV, including the Company, designated a portion of their partnership interest for the purpose of providing an interest in the partnership to a select group of key employees. Until such time an interest in the partnership is issued to a key employee, all profits, losses, distributions and other rights and obligations relating to such unissued interests remains with the Contributing partners. Each issuance must be authorized by unanimous vote of all Contributing partners. In April 2012, the Contributing partners agreed to provide certain key employees an interest in LSV, thereby reducing the Company’s interest in LSV to approximately 39.8 percent. At June 30, 2012, the Company’s total investment in LSV was $63,553. The investment in LSV exceeded the underlying equity in the net assets of LSV by $3,499, of which $3,062 is considered goodwill embedded in the investment. The Company receives partnership distributions from LSV on a quarterly basis. The Company received partnership distribution payments from LSV for $47,443 and $50,760 in the six months ended June 30, 2012 and 2011, respectively. The Company’s proportionate share in the earnings of LSV was $22,712 and $29,530 during the three months ended June 30, 2012 and 2011, respectively. During the six months ended June 30, 2012 and 2011, the Company's proportionate share in the earnings of LSV was $50,042 and $58,479, respectively. The following table contains the condensed statements of operations of LSV for the three months ended June 30, 2012 and 2011:
The following table contains the condensed statements of operations of LSV for the six months ended June 30, 2012 and 2011:
Guaranty Agreement In April 2011, LSV Employee Group II, LLC agreed to purchase a partnership interest of an existing LSV employee for $4,300, of which $3,655 was financed through a term loan with Bank of America, N.A. (Bank of America). The Company provided an unsecured guaranty to the lenders of all the obligations of LSV Employee Group II, LLC. The lenders have the right to seek payment from the Company in the event of a default by LSV Employee Group II, LLC. The term loan has a four year term and will be repaid from the quarterly distributions of LSV. LSV Employee Group II made principal payments of $468 during the six months ended June 30, 2012. As of June 30, 2012, the remaining unpaid principal balance of the term loan was $2,729. This amount is not reflected, nor is it required to be reflected, in the Company’s Consolidated Balance Sheet at June 30, 2012. The Company’s direct interest in LSV is unchanged as a result of this transaction. The Company has determined that LSV Employee Group II is a variable interest entity (VIE); however, the Company is not considered the primary beneficiary because it does not have the power to direct the activities that most significantly impact the economic performance of LSV Employee Group II either directly or through any financial responsibility from the guaranty. In July 2012, LSV Employee Group II made a principal payment of $272. As of July 31, 2012, the remaining unpaid principal balance of the term loan was $2,457. The Company, in its capacity as guarantor, currently has no obligation of payment relating to the term loan of LSV Employee Group II and, furthermore, fully expects that LSV Employee Group II will meet all of their future obligations regarding the term loan. |

| Variable Interest Entities - Investment Products [Abstract] | |
| Variable Interest Entities - Investment Products | Variable Interest Entities – Investment Products The Company has created numerous investment products for its clients in various types of legal entity structures. The Company serves as the Manager, Administrator and Distributor for these investment products and may also serve as the Trustee for some of the investment products. Clients are the equity investors and participate in proportion to their ownership percentage in the net income and net capital gains of the products, and, on liquidation, will participate in proportion to their ownership percentage in the remaining net assets of the products after satisfaction of outstanding liabilities. Some of the Company’s investment products have been determined to be VIEs at inception. The Company does not have a significant equity investment in any of the VIEs and does not have an obligation to enter into any guarantee agreements with the VIEs. The Company is not the primary beneficiary of the VIEs because the expected fees and the expected return on any investment into the VIE by the Company relative to the expected returns of the VIE to the equity investor holders does not approach 50 percent of the expected losses or gains of the VIEs. Therefore, the Company is not required to consolidate any investment products that are VIEs into its financial statements. The Company’s variable interest in the VIEs, which consists of management fees and in some situations, seed capital, is not considered a significant variable interest. The risks to the Company associated with its involvement with any of the investment products that are VIEs are limited to the cash flows received from the revenue generated for asset management, administration and distribution services and any equity investments in the VIEs. Both of these items are not significant. The Company has no other financial obligation to the VIEs. Amounts relating to fees received from the VIEs included in Receivables and amounts relating to equity investments in the VIEs included in Investments Available for Sale on the Company’s Consolidated Balance Sheets are not significant to the total assets of the Company. |

| Fair Value, by Balance Sheet Grouping, Methodology and Assumptions [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fair Value Measurements | Fair Value Measurements The fair value of the Company’s financial assets and liabilities is determined in accordance with the fair value hierarchy. The fair value of the Company’s Level 1 financial assets consist mainly of investments in equity and fixed-income mutual funds that are quoted daily. Level 2 financial assets consist of Government National Mortgage Association (GNMA) and other U.S. government agency securities that are single issuer pools that are valued based on current market data for the specific issue owned or pools of similar securities. Level 3 financial assets primarily consist of senior note obligations issued by SIVs. The Company had no Level 3 financial liabilities at June 30, 2012 or December 31, 2011. There were no transfers of financial assets between levels within the fair value hierarchy during the six months ended June 30, 2012. Valuation of GNMA and Other U.S. Government Agency Securities All of the Company's GNMA and other U.S. government agency securities are held in accounts at well-established financial institutions that utilize the services of independent pricing vendors. These vendors utilize evaluated and industry accepted pricing models that vary by asset class and incorporate available trade, bid and other market information to determine the fair value of the securities. The market inputs normally used for evaluations of securities, listed in approximate order of priority, include: benchmark yields, reported trade, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data. The Company records the securities at the prices provided by the independent pricing vendor without adjustment. Valuation of SIV Securities The underlying collateral of the SIV securities is mainly comprised of asset-backed securities and collateralized debt obligations. The Company utilizes the services of an independent firm that specializes in securities valuations to assist in determining the fair value of the SIV security owned. Given the lack of any reliable market data on the SIV security, the firm utilized a valuation model that employs a net asset approach which considers the value of the underlying collateral of the SIV security to determine its fair value. Management evaluated the value received from the firm and considered other information, such as the existence of any current market activity, to determine the fair value of the SIV securities. As a result of this evaluation, the Company utilized the fair value of the SIV security without adjustment as provided by the independent valuation firm. The model used by the independent valuation firm to determine the fair value of the SIV security attempts to value the underlying collateral of the SIV security through the use of industry accepted and proprietary valuation techniques and models. This approach combines advanced analytics with real-time market information that incorporate structural and fundamental analysis, collateral characteristics and recent market developments. Each security that makes up the underlying collateral is specifically identified by its CUSIP or ISIN number and is analyzed by using observable collateral characteristics and credit statistics in order to project future performance and expected cash flows for each individual security. The projected cash flows incorporate assumptions and expectations based upon the foregoing analysis of the collateral characteristics such as, but not limited to, default probabilities, recovery rates, prepayment speeds and loss severities. Expected future cash flows are discounted at an appropriate yield derived from the individual security, structural and collateral characteristics, trading levels and other available market data. Different modeling techniques and associated inputs and assumptions may be used to project future cash flows for each security depending upon the asset classification of that individual security (i.e. residential mortgage-backed security, commercial mortgage-backed security, collateralized debt obligations, etc.). The aggregate value of the discounted cash flows of the underlying collateral is compared to the total remaining par value of the collateral to determine the expected recovery price, or fair value, of the remaining note obligations. Other factors may be considered that are specific to the SIV security that may affect the fair value of the SIV security. Management may also consider, when available, price quotes from brokers and dealers. If a price quote is available, management will compare this number to the fair value derived from the valuation model of the independent firm giving consideration to other market factors and risk premiums. Given the lack of any significant trading activity for the SIV security owned by the Company, management believes that market prices may not represent the implied fair value of the SIV security owned by the Company. In the event a market transaction does exist for a SIV security, management evaluates the publicly available information surrounding the transaction in order to assess if the price used represents the fair value for the SIV security. In management’s opinion, the current market for the SIV security does not represent any orderly and efficient market. The fair value of certain financial assets and liabilities of the Company was determined using the following inputs:

| Line of Credit Facility [Abstract] | |
| Lines Of Credit | Lines of Credit On February 2, 2012 (the Closing Date), the Company entered into a new five-year $300,000 Credit Agreement (the Credit Facility) with Wells Fargo Bank, National Association, and a syndicate of other lenders. The Credit Facility became available on the Closing Date and replaced the five-year Credit Agreement with JP Morgan Chase Bank, N.A. The Credit Facility is scheduled to expire in February 2017, at which time any aggregate principal amount of loans outstanding becomes payable in full. Any borrowings made under the Credit Facility will accrue interest at 1.25 percent above LIBOR. There is also a commitment fee equal to 0.15 percent per annum on the daily unused portion of the facility. The aggregate amount of the Credit Facility may be increased by an additional $100,000 under certain conditions set forth in the agreement. The Credit Facility contains covenants that restrict the ability of the Company to engage in mergers, consolidations, asset sales, investments, transactions with affiliates, or to incur liens, as defined in the agreement. In the event of a default under the Credit Facility, the Company would also be restricted from paying dividends on, or repurchasing, its common stock without the approval of the lenders. None of the covenants of the Credit Facility negatively affect the Company’s liquidity or capital resources. Both the interest rate and commitment fee prices may increase if the Company’s leverage ratio reaches certain levels. Upon the occurrence of certain financial or economic events, significant corporate events, or certain other events of default constituting an event of default under the Credit Facility, all loans outstanding may be declared immediately due and payable and all commitments under the agreement may be terminated.

| Stockholders' Equity Note [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Shareholders' Equity | Shareholders’ Equity Stock-Based Compensation The Company currently has one active equity compensation plan, the 2007 Equity Compensation Plan (the 2007 Plan), which provides for the grant of incentive stock options, non-qualified stock options and stock appreciation rights with respect to up to 20 million shares of common stock of the Company, subject to adjustment for stock splits, reclassifications, mergers and other events. Permitted grantees under the 2007 Plan include employees, non-employee directors and consultants who perform services for the Company. The plan is administered by the Compensation Committee of the Board of Directors of the Company. The Company has only granted non-qualified stock options under the plan. All outstanding stock options have performance-based vesting provisions specific to each option grant that tie the vesting of the applicable stock options to the Company’s financial performance. The Company’s stock options vest at a rate of 50 percent when specified diluted earnings per share targets are achieved, and the remaining 50 percent when secondary, higher specified diluted earnings per share targets are achieved. The amount of stock-based compensation expense is based upon management’s estimate of when the earnings per share targets may be achieved. The Company discontinued any further grants under the Company’s 1998 Equity Compensation Plan (the 1998 Plan) as a result of the approval of the 2007 Plan. No options are available for grant from this plan. Grants made from the 1998 Plan continue in effect under the terms of the grant. The Company recognized stock-based compensation expense in its Consolidated Financial Statements in the three months ended June 30, 2012 and 2011, respectively, as follows:
The Company recognized stock-based compensation expense in its Consolidated Financial Statements in the six months ended June 30, 2012 and 2011, respectively, as follows:
As of June 30, 2012, there was approximately $41,397 of unrecognized compensation cost remaining, adjusted for estimated forfeitures, related to unvested employee stock options that management expects will vest and is being amortized. The Company estimates that compensation cost will be recognized according to the following schedule:
The Company issues new common shares associated with the exercise of stock options. The total intrinsic value of options exercised during the six months ended June 30, 2012 was $4,327. The total options exercisable as of June 30, 2012 had an intrinsic value of $26,977. The total intrinsic value for options exercisable is calculated as the difference between the market value of the Company’s common stock as of June 30, 2012 and the exercise price of the shares. The market value of the Company’s common stock as of June 30, 2012 was $19.89 as reported by the Nasdaq Stock Market, LLC. The weighted average exercise price of the options exercisable as of June 30, 2012 was $17.37. Total options that were outstanding and exercisable as of June 30, 2012 were 25,564,000 and 10,712,000, respectively. Common Stock Buyback The Company’s Board of Directors, under multiple authorizations, has authorized the repurchase of the Company’s common stock on the open market or through private transactions. The Company purchased 4,098,000 shares at a total cost of $79,879 during the six months ended June 30, 2012. As of June 30, 2012, the Company has $116,397 of authorization remaining for the purchase of common stock under the program. The Company immediately retires its common stock when purchased. Upon retirement, the Company reduces Capital in excess of par value for the average capital per share outstanding and the remainder is charged against Retained earnings. If the Company reduces its Retained earnings to zero, any subsequent purchases of common stock will be charged entirely to Capital in excess of par value.

| Income Tax Uncertainties [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Income Taxes | Income Taxes The gross liability for unrecognized tax benefits at June 30, 2012 and December 31, 2011 was $11,547 and $9,410, respectively, exclusive of interest and penalties, of which $9,974 and $8,320 would affect the effective tax rate if the Company were to recognize the tax benefit. The Company classifies interest and penalties on unrecognized tax benefits as income tax expense. As of June 30, 2012 and December 31, 2011, the combined amount of accrued interest and penalties related to tax positions taken on tax returns was $853 and $634, respectively.
The Company’s effective tax rates were 36.6 percent and 34.7 percent for the three months ended June 30, 2012 and 2011, respectively. For the six months ended June 30, 2012 and 2011, the Company's tax rates were 36.9 percent and 36.0 percent, respectively. The 2011 tax rate reflects a benefit for research and development tax credit whereas the 2012 tax rate did not reflect any benefit. Additionally, during the three months ended June 30, 2011, management determined the Company was eligible for the Domestic Production Activities Deduction. The effective rate in the three months ended June 30, 2011 reflects the benefit of this deduction for both 2011 and 2010, whereas the 2012 tax rate only reflects the 2012 benefit. The Company files income tax returns in the United States on a consolidated basis and in many U.S. state and foreign jurisdictions. The Company is subject to examination of income tax returns by the Internal Revenue Service (IRS) and other domestic and foreign tax authorities. The Company is no longer subject to U.S. federal income tax examination for years before 2007 and is no longer subject to state, local or foreign income tax examinations by authorities for years before 2006. The Company estimates it will recognize $1,768 of unrecognized tax benefits within the next twelve months due to the expiration of the statute of limitations and resolution of income tax audits. These unrecognized tax benefits are related to tax positions taken on certain federal, state, and foreign tax returns. However, the timing of the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for each year. While it is reasonably possible that some issues under examination could be resolved in the next twelve months, based upon the current facts and circumstances, the Company cannot reasonably estimate the timing of such resolution or total range of potential changes as it relates to the current unrecognized tax benefits that are recorded as part of the Company’s financial statements. |

| Commitments and Contingencies Disclosure [Abstract] | |
| Commitments And Contingencies | Commitments and Contingencies In the normal course of business, the Company is party to various claims and legal proceedings. One of SEI’s principal subsidiaries, SIDCO, has been named as a defendant in certain putative class action complaints (the Complaints) related to leveraged exchange traded funds (ETFs) advised by ProShares Advisors, LLC. The first complaint was filed on August 5, 2009. To date, the Complaints have been filed in the United States District Court for the Southern District of New York and in the United States District Court for the District of Maryland. The three complaints filed in the District of Maryland have been voluntarily dismissed by the plaintiffs. Two of them were subsequently re-filed in the Southern District of New York. Two of the complaints filed in the Southern District of New York have also been voluntarily dismissed by plaintiffs. The Complaints are purportedly made on behalf of all persons that purchased or otherwise acquired shares in various ProShares leveraged ETFs pursuant or traceable to allegedly false and misleading registration statements, prospectuses and statements of additional information. The Complaints name as defendants ProShares Advisors, LLC; ProShares Trust; ProShares Trust II, SIDCO, and various officers and trustees to ProShares Advisors, LLC; ProShares Trust and ProShares Trust II. The Complaints allege that SIDCO was the distributor and principal underwriter for the various ProShares leveraged ETFs that were distributed to authorized participants and ultimately shareholders. The complaints allege that the registration statements for the ProShares ETFs were materially false and misleading because they failed adequately to describe the nature and risks of the investments. The Complaints allege that SIDCO is liable for these purportedly material misstatements and omissions under Section 11 of the Securities Act of 1933. The Complaints seek unspecified compensatory and other damages, reasonable costs and other relief. Defendants have moved to consolidate the complaints, which motion has been granted. The Court appointed lead plaintiff on July 13, 2010, and an amended consolidated class action complaint was filed on September 25, 2010 asserting substantially the same claims. Defendants moved to dismiss on November 15, 2010. On December 16, 2010, lead plaintiff informed the Court and Defendants that lead plaintiff elected to file a second amended consolidated complaint, which was filed on January 31, 2011. Defendants filed a motion to dismiss the second complaint on March 17, 2011. Oral argument on this motion was held on February 2, 2012. While the outcome of this litigation is uncertain given its early phase, SEI believes that it has valid defenses to plaintiffs’ claims and intends to defend the lawsuits vigorously. SEI has been named in six lawsuits filed in Louisiana. Five lawsuits were filed in the 19th Judicial District Court for the Parish of East Baton Rouge, State of Louisiana. One of the five actions purports to set forth claims on behalf of a class and also names SPTC as a defendant. Two of the other actions also name SPTC as a defendant. All five actions name various defendants in addition to SEI, and, in all five actions, the plaintiffs purport to bring a cause of action under the Louisiana Securities Act. The putative class action originally included a claim against SEI and SPTC for an alleged violation of the Louisiana Unfair Trade Practices Act. Two of the other five actions include claims for violations of the Louisiana Racketeering Act and possibly conspiracy. In addition, another group of plaintiffs have filed a lawsuit in the 23rd Judicial District Court for the Parish of Ascension, State of Louisiana, against SEI and SPTC and other defendants asserting claims of negligence, breach of contract, breach of fiduciary duty, violations of the uniform fiduciaries law, negligent misrepresentation, detrimental reliance, violations of the Louisiana Securities Act and Louisiana Racketeering Act and conspiracy. The underlying allegations in all the actions are purportedly related to the role of SPTC in providing back-office services to Stanford Trust Company. The petitions allege that SEI and SPTC aided and abetted or otherwise participated in the sale of “certificates of deposit” issued by Stanford International Bank. Two of the five actions filed in East Baton Rouge have been removed to federal court, and plaintiffs’ motions to remand are pending. These two cases have been transferred by the Judicial Panel on Multidistrict Litigation to United States District Court for the Northern District of Texas. On August 31, 2011, the United States District Court for the Northern District of Texas issued an order and judgment that the causes of action alleged against SEI and SPTC in the two remanded actions were preempted by federal law and the Court dismissed these cases with prejudice. The Court of Appeals for the Fifth Circuit granted an expedited appeal of the United States District Court’s order and judgment. The appeal was briefed, and oral argument was held on February 7, 2012. On March 19, 2012, a panel of the Court of Appeals for the Fifth Circuit reversed the decision of the United States District Court and remanded the actions for further proceedings. On April 2, 2012, SEI filed with the United States Court of Appeals for the Fifth Circuit a petition for rehearing en banc of the panel’s opinion. On April 19, 2012, the Fifth Circuit Court of Appeals denied the petition for rehearing. The case filed in Ascension Parish was also removed to federal court and transferred by the Judicial Panel on Multidistrict Litigation to the Northern District of Texas. The schedule for responding to that complaint has not yet been established. The plaintiffs in the remaining two cases in East Baton Rouge have granted SEI an extension to respond to the filings. SEI and SPTC filed exceptions in the putative class action pending in East Baton Rouge, which the Court granted in part and dismissed the claims under the Louisiana Unfair Trade Practices Act and denied in part as to the other exceptions. SEI and SPTC filed an answer to the East Baton Rouge putative class action; plaintiffs filed a motion for class certification; and SEI and SPTC also filed a motion for summary judgment against certain named plaintiffs which the Court stated will not be set for hearing until after the hearing on the class certification motion. Following the decision by the United States District Court for the Northern District of Texas, the Court in the East Baton Rouge action issued an order staying the proceedings in the East Baton Rouge class action pending the outcome of the appeal of the order and judgment of the United States District Court for the Northern District of Texas. Following the panel opinion of the Court of Appeals on March 19, 2012, the Court in the East Baton Rouge action scheduled a hearing on class certification for September 20, 2012. On July 18, 2012, the Company filed a petition for certiorari in the United States Supreme Court, seeking review of the decision by the United States Court of Appeals for the Eleventh Circuit to permit the claims against SEI to proceed. The Company believes that the trial court correctly concluded that the claims against SEI were barred by the federal Securities Litigation Uniform Standards Act and is requesting that the Supreme Court reinstate that dismissal. While the outcome of this litigation is uncertain given its early phase, SEI and SPTC believe that they have valid defenses to plaintiffs’ claims and intend to defend the lawsuits vigorously. Because of the uncertainty of the make-up of the classes, the specific theories of liability that may survive a motion to dismiss, the lack of discovery regarding damages, causation, mitigation and other aspects that may ultimately bear upon loss, the Company is not reasonably able to provide an estimate of loss, if any, with respect to the foregoing lawsuits. |

| Subsequent Events [Abstract] | |
| Subsequent Events [Text Block] | Subsequent Events On July 31, 2012, the Company, MetLife International Holdings, Inc. (MetLife) and International Finance Corporation (IFC) entered into a definitive agreement with Baring Asset Management Limited to sell all ownership interests in SEI Asset Korea Co., Ltd. (SEI AK). SEI AK is located in South Korea and provides domestic equity and fixed income investment management services to financial institutions and pension funds. Consummation of the acquisition of SEI AK under the definitive agreement is subject to regulatory approvals and other customary closing conditions. The Company's ownership interest in SEI AK is 56.1 percent as of July 31, 2012. The Company consolidates the assets, liabilities and operations of SEI AK in its Consolidated Financial Statements. The ownership interests in SEI AK for MetLife and IFC is reflected in Noncontrolling interest in the Consolidated Financial Statements. Upon closing of the agreement, the then current cash balance of SEI AK will be distributed to the Company, Metlife and IFC in accordance with the ownership interests. As of June 30, 2012, SEI AK has total corporate assets of $48,776, of which $42,553 is included in Cash and Cash equivalents on the Consolidated Balance Sheets. All other accounts of SEI AK are not material to any financial statement line item in the Consolidated Financial Statements. The Company did not provide U.S. deferred taxes on the undistributed earnings of SEI AK since its inception because those earnings were considered to be indefinitely reinvested. As a result of the potential sale of SEI AK, the Company no longer considers undistributed earnings to be indefinitely reinvested and, therefore, must accrue approximately $5,000 for U.S. deferred taxes during the three months ended September 30, 2012 on the cumulative undistributed earnings of SEI AK. If the requisite regulatory approvals are obtained, the other conditions to closing are satisfied or waived and the transaction is consummated, then the Company expects to recognize a net after tax gain on the sale of its shares of SEI AK depending upon revenue during a pre-closing measurement period and specified revenues during three one-year periods after the closing. |

Employee stock options to purchase 16,637,000 and 7,675,000 shares of common stock, with an average exercise price of $22.75 and $28.25, were outstanding during the three months ended June 30, 2012 and 2011, respectively, but not included in the computation of diluted earnings per common share because the effect on diluted earnings per common share would have been anti-dilutive. The calculations of basic and diluted earnings per share for the six months ended June 30, 2012 and 2011 are:
Employee stock options to purchase 14,017,000 and 7,606,000 shares of common stock, with an average exercise price of $23.40 and $28.26, were outstanding during the six months ended June 30, 2012 and 2011, respectively, but not included in the computation of diluted earnings per common share because the effect on diluted earnings per common share would have been anti-dilutive. |

| Equity Method Investments, Policy [Policy Text Block] | The Company has an investment in the general partnership LSV Asset Management (LSV). LSV is a registered investment advisor that provides investment advisory services to institutions, including pension plans and investment companies. LSV is currently an investment sub-advisor for a small number of SEI-sponsored mutual funds. The Company accounts for its interest in LSV using the equity method because of its less than 50 percent ownership. The Company’s interest in the net assets of LSV is reflected in Investment in unconsolidated affiliate on the accompanying Consolidated Balance Sheets and its interest in the earnings of LSV is reflected in Equity in earnings of unconsolidated affiliate on the accompanying Consolidated Statements of Operations. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Consolidation, Variable Interest Entity, Policy [Policy Text Block] | The Company does not have a significant equity investment in any of the VIEs and does not have an obligation to enter into any guarantee agreements with the VIEs. The Company is not the primary beneficiary of the VIEs because the expected fees and the expected return on any investment into the VIE by the Company relative to the expected returns of the VIE to the equity investor holders does not approach 50 percent of the expected losses or gains of the VIEs. Therefore, the Company is not required to consolidate any investment products that are VIEs into its financial statements. The Company’s variable interest in the VIEs, which consists of management fees and in some situations, seed capital, is not considered a significant variable interest. The risks to the Company associated with its involvement with any of the investment products that are VIEs are limited to the cash flows received from the revenue generated for asset management, administration and distribution services and any equity investments in the VIEs. Both of these items are not significant. The Company has no other financial obligation to the VIEs. Amounts relating to fees received from the VIEs included in Receivables and amounts relating to equity investments in the VIEs included in Investments Available for Sale on the Company’s Consolidated Balance Sheets are not significant to the total assets of the Company. |

| Fair Value of Financial Instruments, Policy [Policy Text Block] | The fair value of the Company’s financial assets and liabilities is determined in accordance with the fair value hierarchy. The fair value of the Company’s Level 1 financial assets consist mainly of investments in equity and fixed-income mutual funds that are quoted daily. Level 2 financial assets consist of Government National Mortgage Association (GNMA) and other U.S. government agency securities that are single issuer pools that are valued based on current market data for the specific issue owned or pools of similar securities. Level 3 financial assets primarily consist of senior note obligations issued by SIVs. The Company had no Level 3 financial liabilities at June 30, 2012 or December 31, 2011. There were no transfers of financial assets between levels within the fair value hierarchy during the six months ended June 30, 2012. |

Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation).

Sum of the carrying amounts as of the balance sheet date of all assets that are recognized. Assets are probable future economic benefits obtained or controlled by an entity as a result of past transactions or events. Reference 1: http://www.xbrl.org/2003/role/presentationRef

- Definition
Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation).
