 # How to use the NPER Function in Excel

In this article, we will learn how to use the NPER function to calculate periods on payments in Excel.
Excel let’s a person find total monthly installment periods  on a loan amount using the function having principle amount or loan amount, interest rate per period, installment amount & number of periods in a year.
The function calculates the payment periods for a loan based on constant payments and a constant interest rate.
Syntax:

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

Syntax for loan calculation formula:-
rate – The interest rate per period.
pmt – installment, amount paid on each period.
pv – The present value, the total amount that a series of future payments is worth now.
[fv] - [optional] pending amount after the loan. If omitted, default is zero.
[type] – [optional] The timing of the payment, either at the beginning or end of the period. Numbers 0 or 1 represent the payment date. The number 0 represents payment at the end of the period, and the number 1 represents
payment at the beginning of the period. The default (empty argument) is 0. The calculation considers payment is at the end of the period.

All of the above might be confusing for some people, so let’s gear up & start learning its usage in excel with the example.

Consider a scenario, John has taken a loan of \$10,000 from a bank at 5% per year interest, paying \$190 every month. He needs to find out his total number of payments on the loan.

So he added the following details in Excel. Here the John is paying every month. So there would be 12 payments a year.
Use the formula in B6 cell

=NPER(B2/12,C2,A2) Here all the arguments to the function is given as cell reference.
You must be wondering why Interest rate is divided by 12 as there are 12 periods of payment in a year & John has to pay \$190 per month till 60 months. You must be wondering why this amount in the function taken as negative. The loan amount is positive value which is credited to John. He has to pay that amount which is to be debited.
