payments (in a repeating field) made at regular
intervals using a fixed interest rate (in a number
field) per interval. (When payments contains equal
values, use the PV function.)
PMT (principal, interest rate, term) Returns the payment needed to meet the
requirements of principal, interest rate, term
PV (payment, interest rate, periods) Returns the present value of equal payments made
