PPMT function

This article describes the formula syntax and usage of the PPMT function in Microsoft Excel.

Description

Returns the payment on the principal for a given period for an investment based on periodic, constant payments and a constant interest rate.

Syntax

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

Note: For a more complete description of the arguments in PPMT, see PV.

The PPMT function syntax has the following arguments:

• Rate    Required. The interest rate per period.

• Per    Required. Specifies the period and must be in the range 1 to nper.

• Nper    Required. The total number of payment periods in an annuity.

• Pv    Required. The present value — the total amount that a series of future payments is worth 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 (zero), that is, the future value of a loan is 0.

• Type    Optional. The number 0 or 1 and indicates when payments are due.

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

Remarks

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.
