"You invest $8,500 now and receive $3,000 at the end of year 1, $2,800 at the end of year 2, $2,600 at the end of year 3, and so on. In what year do you break even on your investment? Use the discounted payback approach and assume an annual interest rate of 4.5%, compounded annually. Enter your answer as an integer."

Answer
Payback period is the duration taken by a project to
recovers its initial inestment.Payback period is calculated by
using cumulative cash flows. Discounted cumulative cash flows are
calculated as follows
All the inflows are discounted at 4.5% by dividing by (1+4.5%)n
where n is the year of cash inflow
Example 3000/(1.045) = 2870.813
Year | Cash flow | PV of cash flow | Cumulative cash flows |
1 | 3000 | 2870.813 | 2870.813 |
2 | 2800 | 2564.044 | 5434.857 |
3 | 2600 | 2278.371 | 7713.228 |
4 | 2400 | 2012.547 | 9725.776 |
It is clear that payback period will be between 3 to 4 years
It is calculated as A + B/C
where A is the year before recovery
b is the balance amount recovered
C is the inflow in the recovery year
Discounted . P. B period = 3 +
(8500-7713.228)/2012.547
=3+ 786.772/2012.547
= 3+ 0.390
= 3.390 years
