PPMT function
This article describes the formula syntax and usage of the PPMTfunction 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 fouryear 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.
