PMT Function
The PMT function calculates the periodic payment for a loan, given the principal, interest rate, and number of periods in the life of the loan. It uses the same formula as the FV (future value) function (see FV Function).
This function has the following syntax:
PMT(pv = value, i = value, nper = value [, fv = value, paybegin])
Note:  Paybegin is either 1 or 0, indicating that the payment is made at the beginning or end of the period.
