PMT function
Calculates the payment for a loan based on constant payments and a constant interest rate.
Syntax
PMT(rate,nper,pv,fv,type)
For a more complete description of the arguments in PMT, see the PV function.
Rate is the interest rate for the loan.
Nper is the total number of payments for the loan.
Pv is the present value, or the total amount that a series of future payments is worth now; also known as the principal.
Fv is 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 is the number 0 (zero) 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

The payment returned by PMT includes principal and interest but no taxes, reserve payments, or fees sometimes associated with loans.

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 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 percent for rate and 4 for nper.
Tip To find the total amount paid over the duration of the loan, multiply the returned PMT value by nper.

Note The interest rate is divided by 12 to get a monthly rate. The number of years the money is paid out is multiplied by 12 to get the number of payments.
