You are buying a sofa. You will pay $200 today and make three
consecutive annual payments of $300 in the future. The real rate of
return is 7.5 percent, and the expected inflation rate is 4
percent. What is the actual price of the sofa? (Round
intermediate calculation and final answer to 2 decimal places, e.g.
15.25.)
Actual price | $ |
Given,
Payment today = $200
Consecutive annual payments (A) = $300
No. of consecutive annual payments (n) = 3
Real rate of return = 7.5% or 0.075
Expected inflation rate = 4% or 0.04
Solution :-
Nominal rate of return (r) = [(1 + real rate of return) x (1 + nominal rate of return)] - 1
= [(1 + 0.075) x (1 + 0.04)] - 1
= [(1.075) x (1.04)] - 1
= 1.118 - 1 = 0.118
Actual price
= payment today + [A/r x {1 - (1 + r)-n}]
= $200 + [$300/0.118 x {1 - (1 + 0.118)-3}]
= $200 + [$300/0.118 x {1 - (1.118)-3}]
= $200 + [$300/0.118 x {1 - 0.71560701517}]
= $200 + [$300/0.118 x 0.28439298483]
= $200 + $723.03
= $923.03
