Answer: -0.36%
Explanation:
The actual real after tax rate of return on an investment is calculated simply by taking the after-tax return and subtracting the inflation rate.
For our question then the equation would look something like this,
= (0.04 x (1- (0.28+0.06)) - 0.03
The equation shows how first we adjust the rate for taxes (after - tax return) and then subtract the inflation rate.
= (0.04 x (1- (0.28+0.06)) - 0.03
= -0.0036
= -0.36%
The investor's actual real after tax rate of return is therefore -0.36%.
