## Examples

### Without future value and due date type

The **NPER** function has 3 required arguments: **rate, pmt** and **pv**. Using these arguments, you can calculate the number of payment periods for constant payments. The function assumes payments are paid at the end of each period, and the loan is to be paid in full.

For example, the following formula calculates the number of periods for a loan amount $100,000 with a 6% annual interest, which will be paid for the amount of $3,042.69 each period.

### With future value and due date type

You can specify a target cash balance for after the last payment is made, and whether payments are to be made at the beginning of each period or the end.

The following formula is the extended version of the first example. It calculates same loan amount for the same period amount with the same interest. The difference is that there is $50,000 left after the last payment and payments are made at the beginning of each period.
