Mutual Funds
A mutual fund is a professionally-managed trust that pools the savings of many investors and invests them in securities like stocks, bonds, short-term money market instruments and commodities such as Gold. Investors in a mutual fund have a common financial goal and their money is invested in different asset classes in accordance with the fund’s investment objective. Investments in mutual funds entail comparatively small amounts, giving retail investors the advantage of having finance professionals control their money even if it is a few thousand rupees.
Mutual funds are pooled investment vehicles actively managed either by professional fund managers or passively tracked by an index or industry. The funds are generally well diversified to offset potential losses. They offer an attractive way for savings to be managed in a passive manner without paying high fees or requiring constant attention from individual investors. Mutual funds present an option for investors who lack the time or knowledge to make traditional and complex investment decisions. By putting your money in a mutual fund, you permit the portfolio manager to make those essential decisions for you.

NAV

In order to calculate the NAV of a mutual fund, you need to take the current market value of the fund's assets minus the liabilities, if any and divide it by the number of shares outstanding. NAV is calculated as follows:
For example, if the market value of securities of a Mutual Fund scheme is 
300 lakh and the Mutual Fund has issued 10 lakh units of 10 each to investors, then the NAV per unit of the fund is 30.
