NPER

Definition of NPER:

This formula calculates the number of payment periods for an investment based on constant-amount periodic payments and a constant interest rate.

Sample Usage

NPER(2,500,40000)

NPER(A2,B2,C2,D2,1)

Syntax

NPER(rate, payment_amount, present_value, [future_value, end_or_beginning])

• rate - The interest rate.

• payment_amount - The amount of each payment made.

• present_value - The current value of the annuity.

• future_value - [ OPTIONAL ] - The future value remaining after the final payment has been made.

• end_or_beginning - [ OPTIONAL - 0 by default ] - Whether payments are due at the end (0) or beginning (1) of each period.

Notes

• Ensure that consistent units are used for rate and payment_amount. For example, a car loan for 36 months may be paid monthly, in which case the annual percentage rate should be divided by 12 and the payment_amount is the amount of each monthly payment. On the other hand, a different type of loan of the same length and principal might be paid quarterly, in which case the annual percentage rate should be divided by 4 and the amount paid each period would be adjusted accordingly..
