Returns a value specifying the future value of an annuity
The FV function Returns a value specifying the future value of an annuity based on periodic, fixed payments and a fixed interest rate.
An annuity is a series of fixed cash payments made over time. An annuity can be a loan (such as a home mortgage) or an investment (such as a monthly savings plan).
The Rate and NPer arguments must be calculated using payment periods expressed in the same units. For example, if Rate is calculated using months, NPer must also be calculated using months.
For all arguments, cash paid out (such as deposits to savings) is represented by negative numbers; cash received (such as dividend checks) is represented by positive numbers.

Interest rate
The interest rate per period. For example, if you get a car loan at an annual percentage rate (APR) of 10 percent and make monthly payments, the rate per period is 0.1/12, or 0.0083.
Number of periods
The total number of payment periods in the annuity. For example, if you make monthly payments on a fouryear car loan, your loan has a total of 4 x 12 (or 48) payment periods.
Payment of each period
The payment to be made each period. Payments usually contain principal and interest that doesn't change over the life of the annuity.
Present value
The present value (or lump sum) of a series of future payments. For example, when you borrow money to buy a car, the loan amount is the present value to the lender of the monthly car payments you will make. The default is 0.
Due
Due date specifies when payments are due. This argument must be either End of Period if payments are due at the end of the payment period, or Begin of Period if payments are due at the beginning of the period.
