If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective.</p><p><i><b>Banking Industry Risk. </b></i> An adverse development in the banking industry may affect the value of the Fund's investments more than if they were not invested to such a degree in the banking industry. Banks may be particularly susceptible to certain economic factors such as interest rate changes, adverse developments in the real estate market, fiscal and monetary policy and general economic cycles.</p> <p><i><b>Credit/Default Risk. </b></i> An issuer or guarantor of a security held by the Fund, or a bank or other financial institution that has entered into a repurchase agreement with the Fund, may default on its obligation to pay interest and repay principal. Additionally, the credit quality of securities may deteriorate rapidly, which may impair the Fund's liquidity and cause significant NAV deterioration.</p><p><i><b>Foreign Risk. </b></i> Foreign securities may be subject to risk of loss because of political, financial and economic events in foreign countries, less public information, less stringent foreign securities regulations and accounting and disclosure standards, problems in security registration or settlement and custody or other factors.</p><p><i><b>Interest Rate Risk. </b></i> When interest rates increase, the Fund's yield will tend to be lower than prevailing market rates, and the market value of its securities may also be adversely affected. A low interest rate environment poses additional risks to the Fund, because low yields on the Fund's portfolio holdings may have an adverse impact on the Fund's ability to provide a positive yield to its shareholders, pay expenses out of Fund assets, or, at times, maintain a stable $1.00 share price.</p><p><i><b>Liquidity Risk. </b></i> The Fund may make investments that may become less liquid in response to market developments or adverse investor perception. The liquidity of portfolio securities can deteriorate rapidly due to credit events affecting issuers or guarantors or due to general market conditions or a lack of willing buyers. An inability to sell one or more portfolio positions, or selling such positions at an unfavorable time and/or under unfavorable conditions, can adversely affect the Fund's ability to maintain a $1.00 share price. Liquidity risk may also refer to the risk that the Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests, or other reasons. Certain shareholders may own or control a significant percentage of the Fund's shares, and redemptions by these shareholder of their Fund shares may further increase the Fund's liquidity risk and may adversely impact the Fund's NAV.</p><p><i><b>Market Risk. </b></i> The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular industry sectors or governments and/or general economic conditions.</p><p><i><b>Regulatory Risk. </b></i> The Securities and Exchange Commission (“SEC”) has recently adopted amendments to money market fund regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds, and may adopt additional amendments in the future. These changes may adversely affect the Fund's return potential.</p><p><i><b>Stable NAV Risk. </b></i> The Fund may not be able to maintain a NAV per share of $1.00 at all times. If any money market fund fails to maintain a stable NAV (or if there is a perceived threat of such a failure), other money market funds, including the Fund, could be subject to increased redemption activity, which could adversely affect the Fund's NAV. Shareholders of the Fund should not rely on or expect the Investment Adviser or an affiliate to purchase distressed assets from the Fund, make capital infusions into the Fund, enter into capital support agreements with the Fund or take other actions to help the Fund maintain a stable $1.00 share price.</p><p><i><b>U.S. Government Securities Risk. </b></i> The U.S. government may not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.

The Fund's past performance is not necessarily an indication of how the Fund will perform in the future. Performance reflects expense limitations and fee waivers in effect. In addition, performance reflects Fund level expenses but does not reflect the fees and expenses associated with any variable annuity contract or variable life insurance policy that uses the Fund as an investment option for any contract or policy. Had performance reflected all of those fees and expenses, performance would have been reduced.

Present the corresponding numerical return adjacent to each bar. If the Fund's fiscal year is other than a calendar year, include the year-to-date return information as of the end of the most recent quarter in a footnote to the bar chart. Following the bar chart, disclose the Fund's highest and lowest return for a quarter during the 10 years or other period of the bar chart. Provide annual total returns beginning with the earliest calendar year. Calculate annual returns using the Instructions to Item 8(a), except that the calculations should be based on calendar years. If a Fund's shares are sold subject to a sales load or account fees, state that sales loads or account fees are not reflected in the bar chart and that, if these amounts were reflected, returns would be less than those shown. When a Multiple Class Fund offers more than one Class in the prospectus, provide annual total returns in the bar chart for only one of those Classes. The Fund can select which Class to include (e.g., the oldest Class, the Class with the greatest net assets). When a Multiple Class Fund offering one or more Classes offers a new Class in a prospectus that does not offer the shares of any other Class, include the bar chart with annual total returns for any other existing Class for the first year that the Class is offered. Explain in a footnote that the returns are for a Class that is not offered in the prospectus that would have substantially similar annual returns because the shares are invested in the same portfolio of securities and the annual returns would differ only to the extent that the Classes do not have the same expenses. Include return information for the other Class reflected in the bar chart in the performance table.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 2 -Subparagraph instructions -Clause 3 -Exhibit b -Subsection b falsefalseAnnual Return Caption [Text]20false0rr_BarChartTableTextBlockrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<div><div> &lt;div style="display:none;" &gt;~ http://goldmansachsfunds.com/role/AnnualTotalReturnsBarChartGoldmanSachsMoneyMarketFundServiceShares column period compact * column rr_ProspectusShareClassAxis compact * row primary compact * row rr_DocumentInformationDocumentAxis compact gssqx_S000009354_Member * row dei_LegalEntityAxis compact gssqx_Prospectus_Ten_Member * ~&lt;/div&gt; </div></div>falsefalseBarChart16.jpg<div><div> &lt;div style="display:none;" &gt;~ http://goldmansachsfunds.com/role/AnnualTotalReturnsBarChartGoldmanSachsMoneyMarketFundServiceShares column period compact * column rr_ProspectusShareClassAxis compact * row primary compact * row rr_DocumentInformationDocumentAxis compact gssqx_S000009354_Member * row dei_LegalEntityAxis compact gssqx_Prospectus_Ten_Member * ~&lt;/div&gt; </div></div>falsehttp://goldmansachsfunds.com/role/AnnualTotalReturnsBarChartGoldmanSachsMoneyMarketFundServiceSharesfalsefalse0200515 - Schedule - Annual Total Returns (Bar Chart)truefalsefalse1falseColumnperiodPeriod*Columnrr_ProspectusShareClassAxisAxis*ColumnunitUnit*duration2010-05-01T00:00:002011-04-30T00:00:00falsefalseService Shares, Goldman Sachs Money Market Fundrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldigssqx_C000025638Memberrr_ProspectusShareClassAxisexplicitMemberService Shares, Goldman Sachs Money Market FundUSDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170falseUSDfalsefalse$1falseRowprimaryElement*4false0rr_AnnualReturn2007rrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseverboselabel1truetruefalse0.04980.0498falsefalsefalsetruefalseOtherxbrli:pureItemTypepureIf the Fund has annual returns for at least one calendar year, provide a bar chart showing the Fund's annual total returns for each of the last 10 calendar years (or for the life of the Fund if less than 10 years), but only for periods subsequent to the effective date of the Fund's registration statement.
