An investment project has annual cash inflows of $4,392, $3,276, $4,222, and $3,268 for the next four years, respectively, and a discount rate of 15%.
What is the discounted payback if the initial investment is $5,500? (Round answer to 2 decimal places. Do not round intermediate calculations)
Initial investment = $5,500
Payback period is the time period required to cover the initial investment back. Discounted payback period takes in to account the time value of money of future cash inflows.
| Time | Cash inflows(in $) | PVF(15%,n) | PV of cash inflows(in $) | Cumulative value of cash inflow(in $) | 
| 1 | 4392 | 0.870 | 3821.04 | 3821.04 | 
| 2 | 3276 | 0.756 | 2476.656 | 6297.696 | 
| 3 | 4222 | 0.658 | 2778.076 | 9075.772 | 
| 4 | 3268 | 0.572 | 1869.296 | 10945.068 | 
Note : It is assumed that all the cash flows are evenly distributed through out the year.
Discounted payback period = 1 + 1678.96 / 2476.656
( As the initial investment is $5500, we need to cover this cost, we will take year corresponding to the cumulative value which is less than or equal to 5500, here it is 1 year. In 1 year 3821.04 $ will be covered, we will be needing $1678.96 (5500 - 3821.04) more to cover full initial cost. As the cash flows are evenly distributed, remaining 1678.96 $ will be covered from 2nd year inflows of amount 2476.656$) . Hence 1678.96 / 2476.656 is taken.
= 1 + 0.68 (approx)
= 1.68 years (approx)
