# IPMT function: Description, Usage, Syntax, Examples and Explanation

## What is IPMT function in Excel?

IPMT function is one of the Financial functions in Microsoft Excel that returns the interest payment for a given period for an investment based on periodic, constant payments and a constant interest rate.

## Syntax of IPMT function

IPMT(rate, per, nper, pv, [fv], [type])

The IPMT function syntax has the following arguments:

• Rate: The interest rate per period.
• Per: The period for which you want to find the interest and must be in the range 1 to nper.
• Nper: The total number of payment periods in an annuity.
• Pv: The present value, or the lump-sum amount that a series of future payments is worth right now.
• Fv (Optional): 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).
• Type (Optional): The number 0 or 1 and indicates when payments are due. If type is omitted, it is assumed to be 0.

## IPMT formula explanation

• 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.
