| | | The "rate" and "nper" must have the same units. |
| | | Payment periods are numbered beginning with 1. |
| | | If "rate" <= 0 then #NUM! is returned. |
| | | If "nper" is not an integer, it is truncated. |
| | | If "nper" <= 0, then #NUM! is returned. |
| | | If "pv" <= 0, then #NUM! is returned. |
| | | If "start_period" is not an integer, it is truncated. |
| | | If "start_period" < 1, then #NUM! is returned. |
| | | If "end_period" is not an integer, it is truncated. |
| | | If "end_period" < 1, then #NUM! is returned. |
| | | If "start_period" > "end_period", then #NUM! is returned. |
| | | If "type" is not an integer, it is truncated. |
| | | If "type" is any number other than 0 or 1, then #NUM! is returned. |
| | | Example - If you make monthly payments on a four-year loan at an annual interest rate of 12 percent, use 12%/12 for rate and 4*12 for nper. If you make annual payments on the same loan, use 12% for rate and 4 for nper. |
