This function returns the number of periods for an investment based on a present value, future value, periodic payments, and a specified interest rate.
NPER(rate,paymt,pval,fval,type)
This function has these arguments:
| Argument | Description |
|---|---|
| rate | Interest rate expressed as percentage (per period) |
| paymt | Payment made each period; cannot change over life of the annuity |
| pval | Present value |
| fval | [Optional] Future value; if omitted, the calculation uses zero (0) |
| type | [Optional] Indicates when payments are due; at the end (0) or beginning (1) of the period; if omitted, the calculation uses the end (0) |
For the arguments, money paid out (such as deposits in an investment) is represented by negative numbers; money you receive (such as dividend checks) is represented by positive numbers.
Be sure to express the interest rate as per period. For example, if you make monthly payments on a loan at 8 percent interest, use 0.08/12 for the rate argument.
See the PV function for the equations for calculating financial values.
Accepts numeric data for all arguments. Returns numeric data.
