Interest Conversion Worksheet
Note: The calculator categorizes variables by their method of entry. (See
“Types of Worksheet Variables” on page 18.)
Comparing the Nominal Interest Rate of Investments
Comparing the nominal interest rate (annual percentage rate) of
investments is misleading when the investments have the same nominal
rate but different numbers of compounding periods per year.
To make a more valid comparison, convert the nominal interest rate
(
NOM) to the annual effective interest rate (EFF) for each investment.
The nominal interest rate (
NOM) is the interest rate per compounding
period multiplied by the number of compounding periods per year.
The annual effective interest rate (
EFF) is the compound annual
interest rate that you actually earn for the period of time stated.
