Would you rather purchase a used car that costs $1050 up-front
and will cost $300/year to run or a used car that costs $1300
up-front and will cost $250/year to run? Assume that you will own
the car for 5 years and your discount rate is 5%
Discount rate (d) = 5%
Present valeu can be calculated as R / (1 + d)n
R = Run cost in that year
n = nth year
Present value to run in 1st year of car = 300 / (1 + 0.05)1 = 285.71
Present value to run in 2nd year of car = 300 / (1 + 0.05)2 = 272.1
Present value to run in 3rd year of car = 300 / (1 + 0.05)3 = 259.15
Present value to run in 4th year of car = 300 / (1 + 0.05)4 = 246.81
Present value to run in 5th year of car = 300 / (1 + 0.05)5 = 235.05
Sum of all present value to run the car = 1,298.81
Total present value of purchasing this car = 1,050 + 1,298.82 = 2,348.82
Present value to run in 1st year of car = 250 / (1 + 0.05)1 = 238.09
Present value to run in 2nd year of car = 250 / (1 + 0.05)2 = 226.75
Present value to run in 3rd year of car = 250 / (1 + 0.05)3 = 215.95
Present value to run in 4th year of car = 250 / (1 + 0.05)4 = 205.67
Present value to run in 5th year of car = 250 / (1 + 0.05)5 = 195.88
Sum of all present value to run the car = 1,082.34
Total present value of purchasing this car = 1,300 + 1,082.34 = 2,382.34
