Diagram attached if it makes it clearer |
(1 + real interest rate) x (1 + inflation rate) = (1 + nominal interest rate)
=> (1 + real interest rate) = (1 + nominal interest rate) / (1 + inflation rate)
1 + real interest rate = 1.02/1.05
"real interest rate" = - 0.02857....
So $100 investment gives a real repayment of:
100 x (1 + - 0.02857) = $97.14
