Answer:
In simple terms 5%
or
According to Fisher formula 4.67%
Step-by-step explanation:
Nominal rate of return is the inflation adjusted rate of return. Real rate is the rate before inflation. Nominal rate is the sum of real rate and Inflation rate as well.
Simple Method:
Nominal Rate = Real Rate + Inflation Rate
12% = 7% + Inflation Rate
Inflation Rate = 12% - 7%
Inflation Rate = 5%
Using Fisher Effect Formula:
( 1+ n ) = ( 1 + r ) ( 1 + i )
( 1+ 0.12 ) = ( 1 + 0.07 ) ( 1 + i )
1.12 = 1.07 x ( 1 + i )
( 1 + i ) = 1.12 / 1.07
1 + i = 1.467
i = 1.467 - 1
i = 0.467
i = 4.67%
