John has purchased some machinery for his company and has the choice of making payments as follows:
Option A: $10,000 now.
Option B: $6,000 now and $6,000 at the end of 10 years.
Option C: $ 2,500 now and $1000 at the end of each year for 10 years.
If the interest rate is 7%, which option would he select?
I will calculate the present value of amount received in every option available, option with maximum present value will be selected.
Interest rate (r) = 7%
Option 1: Present value = 10,000
Option 2: 6,000 now
Presemt value of 6,000 at the end of 10 years [6,000 / (1 + 0.07)^10] = 3,050.09
Sum of present value of option 2 = 6,000 + 3,050.09 = 9,050.09
Option 3: 2,500 now
Present value of amount P at the end of each year can be calculated using formula: P * {[1 - (1 + r)^-n] / r}
where n is number of payment received
Present value of annual payment: 1,000 * {[1 - (1 + 0.07)^-10] / 0.07} = 7,023.58
Sum of present value = 2,500 + 7,023.58 = 9,523.58
Option 1 must be selected due to highest present value.
