NPer Function

Returns the number of periods for an annuity based on periodic, constant payments and a constant interest rate.


NPer(rate, pmt, pv, fv, due)


An annuity is a series of constant cash payments made over a period of time.  An annuity can be a loan (such as a home mortgage) or an investment (such as a monthly savings plan).

The NPer function uses the following numeric arguments:

Argument     Description


rate               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.

pmt                Payment to be made each period.  Payments usually contain principal and interest that doesn't change over the life of the annuity.

pv                  Present value, or value today, of a series of future payments or receipts.  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.

fv                  Future value or cash balance you want after you've made the final payment.  The future value of a loan, for instance, is $0.  As another example, if you will need $50,000 in 18 years to pay for your child's education, then $50,000 is the future value.

due                Number indicating when payments are due.  Use 0 if payments are due at the end of the payment period, and use 1 if payments are due at the beginning of the period.


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.
