Fees and Expenses of the Fund This table describes the fees and expenses that you may pay if you buy and hold shares of Mid-Cap Growth Equity. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $25,000 in the fund complex advised by BlackRock Advisors, LLC (“BlackRock”). More information about these and other discounts is available from your financial professional and in the “Details About the Share Classes” section on page 21 of the Fund’s prospectus and in the “Purchase of Shares” section on page II-58 of the Fund’s statement of additional information. Fund Overview Key Facts About BlackRock Mid-Cap Growth Equity Portfolio Shareholder Fees (fees paid directly from your investment) Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that 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: Example: You would pay the following expenses if you did not redeem your shares: 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 and may result in higher taxes when 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 Fund’s portfolio turnover rate was 88% of the average value of its portfolio. Principal Investment Strategies of the Fund Principal Risks of Investing in the Fund Risk is inherent in all investing. The value of your investment in Mid-Cap Growth Equity, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The following is a summary description of principal risks of investing in the Fund.<ul type="square"><li style="margin-left:-20px">Convertible Securities Risk — The market value of a convertible security performs like that of a regular debt security; that is, if market interest rates rise, the value of a convertible security usually falls. In addition, convertible securities are subject to the risk that the issuer will not be able to pay interest or dividends when due, and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Since it derives a portion of its value from the common stock into which it may be converted, a convertible security is also subject to the same types of market and issuer risks that apply to the underlying common stock.</li></ul><ul type="square"><li style="margin-left:-20px">Derivatives Risk — The Fund’s use of derivatives may reduce the Fund’s returns and/or increase volatility. Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets. The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately. Derivatives may give rise to a form of leverage and may expose the Fund to greater risk and increase its costs. Recent legislation calls for new regulation of the derivatives markets. The extent and impact of the regulation is not yet known and may not be known for some time. New regulation may make derivatives more costly, may limit the availability of derivatives, or may otherwise adversely affect the value or performance of derivatives.</li></ul><ul type="square"><li style="margin-left:-20px">Equity Securities Risk — Stock markets are volatile. The price of equity securities fluctuates based on changes in a company’s financial condition and overall market and economic conditions.</li></ul><ul type="square"><li style="margin-left:-20px">Investment Style Risk — Under certain market conditions, growth investments have performed better during the later stages of economic expansion. Therefore, this investment style may over time go in and out of favor. At times when the investment style used by the Fund is out of favor, the Fund may underperform other equity funds that use different investment styles.</li></ul><ul type="square"><li style="margin-left:-20px">Leverage Risk — Some transactions may give rise to a form of economic leverage. These transactions may include, among others, derivatives, and may expose the Fund to greater risk and increase its costs. The use of leverage may cause the Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet any required asset segregation requirements. Increases and decreases in the value of the Fund’s portfolio will be magnified when the Fund uses leverage.</li></ul><ul type="square"><li style="margin-left:-20px">Market Risk and Selection Risk — Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Selection risk is the risk that the securities selected by Fund management will underperform the markets, the relevant indices or the securities selected by other funds with similar investment objectives and investment strategies. This means you may lose money.</li></ul><ul type="square"><li style="margin-left:-20px">Mid-Cap Securities Risk — The securities of mid-cap companies generally trade in lower volumes and are generally subject to greater and less predictable price changes than the securities of larger capitalization companies.</li></ul><ul type="square"><li style="margin-left:-20px">“New Issues” Risk — “New Issues” are initial public offerings of equity securities of U.S. and non-U.S. issuers. Securities issued in IPOs have no trading history, and information about the companies may be available for very limited periods. In addition, the prices of securities sold in IPOs may be highly volatile or may decline shortly after the initial public offering.</li></ul> Performance Information The information shows you how Mid-Cap Growth Equity’s performance has varied year by year and provides some indication of the risks of investing in the Fund. The table compares the Fund’s performance to that of the Russell Midcap® Growth Index. As with all such investments, past performance (before and after taxes) is not an indication of future results. Sales charges are not reflected in the bar chart. If they were, returns would be less than those shown. However, the table includes all applicable fees and sales charges. If BlackRock and its affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund’s returns would have been lower.

Principal Investment Strategies of the Fund Small Cap Growth Equity normally invests at least 80% of its net assets in equity securities issued by U.S. small capitalization companies which Fund management believes offer superior prospects for growth. Equity securities consist primarily of common stock, preferred stock, securities convertible into common stock and securities or other instruments whose price is linked to the value of common stock. The Fund management team focuses on U.S. small capitalization emerging growth companies. Although a universal definition of small-capitalization companies does not exist, the Fund generally defines these companies, at the time of the Fund’s investment, as those with market capitalizations comparable in size to the companies in the Russell 2000® Growth Index (between approximately $53 million and $3.771 billion as of June 30, 2012, the most recent rebalance date). In the future, the Fund may define small-capitalization companies using a different index or classification system. The Fund seeks to buy primarily common stock but also can invest in preferred stock, convertible securities and other equity securities. From time to time the Fund may invest in shares of companies through “new issues” or initial public offerings (“IPOs”). 0.335 0.1511 0.1021 0.0598 0.1929 -0.4637 0.4882 0.1502 -0.0335 0.1067 0.5465 0.1009 0.0611 0.1868 0.1497 -0.4008 <div style="display:none">~ http://www.blackrock.com/role/ScheduleAnnualFundOperatingExpensesBLACKROCKSMALLCAPGROWTHEQUITYPORTFOLIO column period compact * ~</div> 0.3416 0.2256 -0.0018 0.1064 <div style="display:none">~ http://www.blackrock.com/role/ScheduleExpenseExampleTransposedBLACKROCKSMALLCAPGROWTHEQUITYPORTFOLIO column period compact * ~</div> 0.0489 0.0489 0.0318 0.0527 0.0877 0.1096 0.1034 0.1581 -0.0143 -0.0143 -0.0121 -0.0153 -0.0113 0.0003 -0.0048 0.0323 0.0483 0.0225 0.0467 0.0531 0.0878 0.1106 0.1459 0.0714 0.0712 0.0631 0.0705 0.0689 0.0817 0.0761 0.0062 0.1032 0.0003 0.0036 0.0049 0.0082 0.0211 0.0349 0.0977 0.0946 0.0863 0.0962 0.0944 0.1077 0.098 <div style="display:none">~ http://www.blackrock.com/role/ScheduleAnnualTotalReturnsBLACKROCKSMALLCAPGROWTHEQUITYPORTFOLIOBarChart column period compact * ~</div> 0.008 0.0025 0.0124 0.0229 -0.0071 0.0158 Investment Objective The investment objective of BlackRock Small Cap Growth Equity Portfolio (“Small Cap Growth Equity” or the “Fund”), a series of BlackRock FundsSM (the “Trust”), is long-term capital appreciation.

The following is a summary description of principal risks of investing in the Fund.<ul type="square"><li style="margin-left:-20px">Convertible Securities Risk — The market value of a convertible security performs like that of a regular debt security; that is, if market interest rates rise, the value of a convertible security usually falls. In addition, convertible securities are subject to the risk that the issuer will not be able to pay interest or dividends when due, and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness.

Equity securities consist primarily of common stock, preferred stock, securities convertible into common stock and securities or other instruments whose price is linked to the value of common stock. Although a universal definition of mid-capitalization companies does not exist, the Fund generally defines these companies, at the time of the Fund’s investment, as those with market capitalizations comparable in size to the companies in the Russell Midcap® Growth Index (between approximately $1.275 billion and $19.075 billion as of June 30, 2012, the most recent rebalance date). In the future, the Fund may define mid-capitalization companies using a different index or classification system. The Fund seeks to buy primarily common stock but also can invest in preferred stock, convertible securities and other equity securities. From time to time the Fund may invest in shares of companies through “new issues” or initial public offerings (“IPOs”). The Fund may, when consistent with the Fund’s investment objective, buy or sell options or futures on a security or an index of securities (commonly known as derivatives). The primary purpose of using derivatives is to attempt to reduce risk to the Fund as a whole (hedge), but they may also be used to maintain liquidity and commit cash pending investment. Fund management also may, but under normal market conditions generally does not intend to, use derivatives for speculation to increase returns. Risk is inherent in all investing. The value of your investment in Mid-Cap Growth Equity, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments.

Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets. The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately. Derivatives may give rise to a form of leverage and may expose the Fund to greater risk and increase its costs. Recent legislation calls for new regulation of the derivatives markets. The extent and impact of the regulation is not yet known and may not be known for some time. New regulation may make derivatives more costly, may limit the availability of derivatives, or may otherwise adversely affect the value or performance of derivatives.</li></ul> <ul type="square"><li style="margin-left:-20px">Equity Securities Risk — Stock markets are volatile.

Principal Investment Strategies of the Fund February 1, 2014 A contingent deferred sales charge ("CDSC") of 1.00% is assessed on certain redemptions of Investor A Shares made within 18 months after purchase where no initial sales charge was paid at time of purchase as part of an investment of $1,000,000 or more. The CDSC is 4.50% if shares are redeemed in less than one year. The CDSC for Investor B Shares decreases for redemptions made in subsequent years. After six years there is no CDSC on Investor B Shares. (See the section "Details About the Share Classes - Investor B Shares" in the Fund's prospectus for the complete schedule of CDSCs.) There is no CDSC on Investor C Shares after one year.
