Calculate the effective interest rate per period given the nominal interest rate per period and the number of compounding intervals per period.
The real interest rate is the rate of interest an investor expects to receive after allowing for inflation. It can be described more formally by the Fisher equation, which states that the real interest rate is approximately the nominal interest rate minus the inflation rate.
