## Description

• This function gives the number of periods for an investment.
• It is based on the period, fixed payments and a fixed interest rate.
• This function calculates number of periods for an investment or a loan with the assumption of constant payments at regular intervals and a fixed interest rate.
• In , is the rate of interest for the period.

0 Payments are due at the end of the period
1 Payments are due at the beginning of the period

## Examples

1. =NPER(14%/12,-1500,-4000,100000,1) = 46.55666767
2. =NPER(10%/12,-750,-2900,800000,1) = 271.42461700707
3. =NPER(10%/12,-750,-2900,800000,0) = 272.292024206798
4. =NPER(15%/12,-300,20000) = 144.2347824
5. =NPER(15%/12,-300,20000,500000) = 392.4483377
