The nominal interest rate on your savings account is 9.14 %, whereas the inflation rate is 7%. What is the real interest rate when you calculate it with the "exact formula"?
A. 2.14% B. 2.30% C. 2% D. 1.5%
> Formula
Real interest rate = [ 1 + Nominal rate ] / [ 1 + Real rate ] - 1
> Calculation
Real interest rate = [ 1 + 0.0914 ] / [ 1 + 0.07 ] - 1
= 1.0914 / 1.07 - 1
= 1.02 - 1
= 0.02 or 2 % Answer
The option C is correct.
