Finance function (Finc)

n: the number of compounding periods.
i: the interest rate per compounding period.
PV: the present value of a compounded amount.
PMT: the periodic payment amount.
FV: the future value of a compounded amount.

Specifying the Number of Compounding Periods and the Periodic Interest Rate

Interest rates are usually quoted at the annual rate (also called the nominal rate): that is, the interest rate per year. However, in compound interest problems, the interest rate entered into i must always be expressed in terms of the basic compounding period, which may be years, months, days, or any other time unit. For example, if a problem involves 6% annual interest compounded quarterly for 5 years, n--the number of quarters--would be 5 x 4 = 20 and i--the interest rate per quarter--would be 6% / 4 = 1.5%. If the interest were instead compounded monthly, n would be 5 x 12 = 60 and i would be 6% / 12 = 0.5%.

Calculating the Number of Payments or Compounding Periods

Press CLRf to clear the financial registers. Enter the periodic interest rate, using i or 12/. Enter at least two of the following values: present value, using PV, payment amount, using PMT, future value, using FV. Press n to calculate the number of payments or periods.

If the answer calculated is not an integer, the calculator rounds the answer up to the next higher integer before storing it in the n register and displaying it. For example, if n were calculated as 318.15, 319 would be the displayed answer. The value of n is rounded up by the calculator to show the total number of payments needed: n-1 equal, full payments, and one final, smaller payment.

Calculating the Periodic and Annual Interest Rates

Press CLRf to clear the financial registers. Enter the number of payments or periods, using n or 12x. Enter at least two of the following values: present value, using PV, payment amount, using PMT, future value, using FV. Press i to calculate the periodic interest rate.

Calculating the Present Value

Press CLRf to clear the financial registers. Enter the number of payments or periods, using n or 12x. Enter the periodic interest rate, using i or 12/. Enter either or both of the following: payment amount, using PMT, future value, using FV. Press PV to calculate the present value.

Calculating the Payment Amount

Press CLRf to clear the financial registers. Enter the number of payments or periods, using n or 12x. Enter the periodic interest rate, using i or 12/. Enter either or both of the following: present value, using PV, future value, using FV. Press PMT to calculate the payment amount.

Calculating the Future Value

Press CLRf to clear the financial registers. Enter the number of payments or periods, using n or 12x. Enter the periodic interest rate, using i or 12/. Enter either or both of the following: present value, using PV, payment amount, using PMT. Press FV to calculate the future value.
