Syntax

NPER(rate,pmt,pv,[fv],[type])

The NPER function has the following arguments:

rate – Required. The rate of interest per period.

pmt – Required. The constant payments to be made during each period, usually, the argument contains principal and interest but no other fees or taxes.

pv – Required. The present value of the loan, a total value of all payment now.

[fv] – Optional. The future value of the loan after the last payment. If omitted, the default value of 0 is taken.

[type] – Optional – Either 1 or 0, indicates when the payment will due.

Type Timing
0 (zero) Payment at the end of the period.
1 Payment at the beginning of the period.

Example

In the following scenario, the NPER function is used to calculate the number of payment periods required to pay back a loan with present value of $50,000, annual interest rate of 13% and yearly constant payments of $5,000.

Result:

Note that periodic payment for the loan is input as negative value because it is the outgoing payment.
