This calculator focuses on time value of money calculations. It stores the interest rate as a periodic rate, ("i%" key instead of "I/YR" key).
It is similar to the HP-12C TVM calculator.
See the Time Value of Money Examples for additional information on this calculator.
This calculator will no longer be included as a download. It has been replaced by the
Time Value of Money with Odd Periods and Compound Interest Calculator and
Time Value of Money with Odd Periods and Simple Interest Calculator that provide the same features but also calculate odd periods.
Also see Time Value of Money Compound Interest Formulas for more information on the different formulas used for fractional number of periods.
