Also known as NAV, this is the unit price (or rupee value) of one unit of a mutual fund. NAV is calculated at the end of every business day. It is calculated by adding up the value of all the securities and cash in the mutual fund's portfolio (its assets), subtracting the fund's liabilities, and dividing that number by the number of units that the fund has issued. It does not include a sales charge. The NAV increases (or decreases) when the value of the mutual fund's holdings increase (or decrease).
