Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Master Portfolio (as defined below) 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 and may result in higher taxes when Fund shares are held in a taxable account. 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 Master Portfolio's turnover rate was 6% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This example is intended to help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The example assumes you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Stock Index Fund pursues its investment objective by seeking to replicate the total return performance of the Index, which is composed of 500 selected common stocks, most of which are listed on the New York Stock Exchange (the “NYSE”).The Stock Index Fund is a feeder fund, meaning that it invests all of its investable assets in a master portfolio. The Fund invests its assets in the S&P 500 Index Master Portfolio (“Master Portfolio”), a separate series of an unaffiliated trust called the Master Investment Portfolio. The Master Portfolio and the Stock Index Fund have substantially similar investment objectives and investment strategies. This structure is sometimes called a “master/feeder” structure. The Fund’s investment results will correspond directly to the investment results of the Master Portfolio.Under normal circumstances, at least 90% of the value of the Master Portfolio’s assets, plus the amount of any borrowing for investment purposes, is invested in securities comprising the Index. The Master Portfolio attempts to achieve, in both rising and falling markets, a correlation of at least 95% between the total return of its net assets before fees and expenses and the total return of the Index.The Master Portfolio seeks to replicate the total return performance of the Index by investing the Master Portfolio’s assets so that the percentage of assets of the Master Portfolio invested in a given stock is approximately the same as the percentage such stock represents in the Index. No attempt is made to manage the Master Portfolio using economic, financial or market analysis. In addition, at times, the portfolio composition of the Master Portfolio may be altered (or “rebalanced”) to reflect changes in the characteristics of the Index. The Master Portfolio is normally rebalanced quarterly during the months of March, June, September and December. In addition, the Master Portfolio may make interim changes in line with the Index.The Master Portfolio also may engage in futures transactions and other derivative securities transactions and lend its portfolio securities, each of which involves risk. The Master Portfolio may use futures contracts and other derivative transactions to manage its short-term liquidity and/or as substitutes for comparable market positions in the securities in its benchmark index. The Master Portfolio may also invest in high-quality money market instruments, including shares of money market funds advised by BlackRock Fund Advisors (“BFA”) or its affiliates.The Master Portfolio reserves the right to concentrate its investments (i.e., invest 25% or more of its total assets in securities of issuers in a particular industry) to approximately the same extent that its benchmark index concentrates in a particular industry.
Risk [Heading]	rr_RiskHeading	<span style="color:#39A872;font-family:Arial;font-size:10pt;font-weight:bold;">Principal Risks</span>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with all investments, you may lose money by investing in the Fund. The value of your investment in the Fund may be affected by one or more of the following risks, which are described in more detail in “Description of Fund Risks” in the Prospectus. The significance of any specific risk to an investment in the Fund will vary over time, depending on the composition of the Fund, market conditions and other factors. You should read all of the risk information presented below carefully, because any one or combination of these risks could adversely affect the Fund's return, the price of the Fund's shares or the Fund's yield.Market Risk The risk that markets will perform poorly or that the returns from the securities in which the Fund invests will underperform returns from the general securities markets or other types of investments. Markets may experience periods of high volatility and reduced liquidity in response to governmental actions or intervention, political, economic or market developments, or other external factors, such as outbreaks of infectious illnesses or other widespread public health issues and outbreaks of war or sanctions in response to military incursions. During those periods, the Fund may experience high levels of shareholder redemptions, and may have to sell securities at times when the Fund would otherwise not do so, and potentially at unfavorable prices. Certain securities may be difficult to value during such periods. These risks may be heightened for fixed income securities in low interest rate environments.Equity Securities Risk Equity securities generally have greater price volatility than fixed-income securities. The market price of equity securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. Equity securities may decline in value due to factors affecting the issuer, equity securities markets generally, particular industries represented in those markets or the issuer itself.Index Fund Risk An index fund has operating and other expenses while an index does not. As a result, while a fund will attempt to track its underlying index as closely as possible, it will tend to underperform the index to some degree over time. If an index fund is properly correlated to its stated index, the Fund will perform poorly when the index performs poorly.Index-Related Risk There is no assurance that the index provider will compile the underlying index accurately, or that the underlying index will be determined, composed or calculated accurately. Gains, losses or costs associated with index provider errors will be borne by the Fund and its shareholders. Unusual market conditions may cause the index provider to postpone a scheduled rebalance, which could cause the underlying index to vary from its normal or expected composition. The postponement of a scheduled rebalance in a time of market volatility could mean that constituents that would otherwise be removed at rebalance due to changes in market capitalizations, issuer credit ratings, or other reasons may remain, causing the performance and constituents of the underlying index to vary from those expected under normal conditions.Passive Investment Risk Because BFA does not select the individual companies in the Index that the Master Portfolio tracks, the Master Portfolio may hold securities of companies that present risks that an investment adviser researching individual securities might otherwise seek to avoid.Tracking Error Risk Tracking error is the divergence of an index fund’s performance from that of the underlying index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Index, pricing differences, transaction costs incurred by the Fund, the Fund's holding of uninvested cash, differences in timing of the accrual of dividends or interest, tax gains or losses, changes to the Index or the need of the Fund or Master Portfolio to meet various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.Derivatives Risk The risk that an investment in derivatives will not perform as anticipated by the Fund’s manager, cannot be closed out at a favorable time or price, or will increase the Fund’s volatility; that derivatives may create investment leverage; that, when a derivative is used as a substitute for or alternative to a direct cash investment, the transaction may not provide a return that corresponds precisely with that of the cash investment; or that, when used for hedging purposes, derivatives will not provide the anticipated protection, causing the Fund to lose money on both the derivatives transaction and the exposure the Fund sought to hedge. The counterparty to a derivatives contract may be unable or unwilling to make timely settlement payments, return the Fund’s margin, or otherwise honor its obligations. Changes in regulation relating to a mutual fund’s use of derivatives and related instruments could potentially limit or impact the Fund’s ability to invest in derivatives, limit a Fund’s ability to employ certain strategies that use derivatives and adversely affect the value or performance of derivatives and the Fund.Money Market Securities Risk The value of a money market instrument typically will decline during periods of rising interest rates, and can also decline in response to changes in the financial condition of the issuer, borrower, counterparty, or underlying collateral assets, or changes in market, economic, industry, political, and regulatory conditions affecting a particular type of security or issuer or fixed income securities generally. Money market funds are not designed to offer capital appreciation. Certain money market funds in which the Fund may invest may impose a fee upon the sale of shares or may temporarily suspend the ability of investors to redeem shares if such fund’s liquidity falls below required minimums, which may adversely affect the Fund’s returns or liquidity.Master/Feeder Structure Risk The Fund pursues its objective by investing substantially all of its assets in another pooled investment vehicle (a “master fund”). The ability of the Fund to meet its investment objective is directly related to the ability of the master fund to meet its investment objective. The Fund will bear its pro rata portion of the expenses incurred by the master fund. Substantial redemptions by other investors in a master fund may affect the master fund’s investment program adversely and limit the ability of the master fund to achieve its objective.Concentration Risk To the extent the Master Portfolio concentrates in a particular industry, it may be more susceptible to economic conditions and risks affecting that industry.
