This will solve for the N, PV, or PMT components of the Time Value of
Money equation where the interest rate is known. To solve the TVM
problem involving a Future Value, see: SR-56 Future Values
Instructions:
1) Clear memories. 2nd Cms.
2) Load known values (you need to enter three of these) into data
memories. Interest rate per period, STO 1, Present Value STO 2, Payment
per period, STO 3, Number of periods STO 4.
3) Calculate the unknown value, press RST, R/S. The unknown value is
automatically calculated and displayed.
