Working with example:

Year 3 | 25 | |||
Year 4 | 25 | |||

Discount rate | 5% | |||
Payback period of this project | = | 100 | / | 25 |
= | 4 | |||

Discounted Payback period: | ||||
Year | Cash Flow | Discount factor | Present Value | Cumulative present value |
x | a | b=1.05^-x | c=a*b | d |
1 | 25 | 0.952381 | 23.81 | 23.81 |
2 | 25 | 0.907029 | 22.68 | 46.49 |
3 | 25 | 0.863838 | 21.60 | 68.08 |
4 | 25 | 0.822702 | 20.57 | 88.65 |
5 | 25 | 0.783526 | 19.59 | 108.24 |
Discounted payback period | = | 4+(100-88.65)/19.59 | ||
= | 4.58 | |||
Discounted payback period of project is 4.58 years. |
