# NPER Calculator

calculate the number of periods that are required to pay off a loan or reach an investment goal through regular periodic payments and at a fixed interest rate.

## How NPER calculator works

Calculates the number of loan payment periods, given the periodic payment amount and (fixed) interest rate.

This NPER calculator uses the following input arguments:

**Rate :** This is the interest rate per period.

**PMT :** The payment made each period. Generally, it contains principal and interest but no other fees and taxes.

**PV :** The present value, or the lump-sum amount that a series of future payments is worth right now.

**FV (optional argument) :** This is the future vale or the cash balance which we want at the end after the last payment is made. When omitted, please enter the value as zero.

**Example**

Lets assume we wish to make an investment of **$10,000** and want to earn **$500,000**.

The annual interest rate is **5%**. We will make additional monthly contributions of **$5,000**.

Lets now calculate the number of monthly investments required to earn **$500,000**.

**Results** : Periods (terms in month) is **85**
