Real rate
From ACT Wiki
A rate which has been restated to exclude the effects of inflation.
The relationship between the Real rate, the Nominal rate and the Inflation rate is:
Real rate = ( (1 + Nominal rate)/(1 + Inflation rate) ) - 1
For example
if the Nominal rate of return = 6% (0.06)
and the Inflation rate = 3% (0.03),
then the Real rate of return = 1.06/1.03 - 1
= 0.0291
= 2.91%.
