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.
