Arguments

Argument	Description	Required/ Optional
Rate	The interest rate per period.	Required
Per	The period for which you want to find the interest and must be in the range 1 to nper.	Required
Nper	The total number of payment periods in an annuity.	Required
Pv	The present value, or the lump-sum amount that a series of future payments is worth right now.	Required
Fv	The future value, or a cash balance you want to attain after the last payment is made. If fv is omitted, it is assumed to be 0 (the future value of a loan, for example, is 0).	Optional

Type Table

Set type equal to	If payments are due
0	At the end of the period
1	At the beginning of the period

Notes

Make sure that you are consistent about the units you use for specifying rate and nper −
- If you make monthly payments on a four-year loan at 12 percent annual interest, 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.
For all the arguments −
- cash you pay out, such as deposits to savings, is represented by negative numbers.
- cash you receive, such as dividend checks, is represented by positive numbers.
If the specified per argument is the specified value of nper, IPMT returns #NUM! error value.
If any of the specified arguments is not recognized as numeric value, IPMT returns #VALUE! error value.
