Find the payback for the investment if you are given an investment of $30,000 and an annual income of 20,000 in the first year that is increasing 3000/year after that for 6 years. Show work.
Solution :- Initial investment = $ 30,000
Year | Annual income | Cumulative annual income |
1 | 20000 | 20000 |
2 | 23000 (20000 + 3000) | 43000 (20000 + 23000) |
3 | 26000 (23000 + 3000) | 69000 (20000 + 23000 + 26000) |
4 | 29000 (26000 + 3000) | 98000 (20000 + 23000 + 26000 + 29000) |
5 | 32000 (29000 + 3000) | 130000 (20000 + 23000 + 26000 + 29000 + 32000) |
6 | 35000 (32000 + 3000) | 165000 (20000 + 23000 + 26000 + 29000 + 32000 + 35000) |
7 | 38000 (35000 + 3000) | 203000 (20000 + 23000 + 26000 + 29000 + 32000 + 35000 + 38000) |
Payback period is the length of time required to recover the initial cost of investment project. In the given question, Pay back period of investment lies between Year 1 and Year 2, accordingly, by interpolation, Payback period is calculated as follows:-
= 1 + (30000 - 20000) / 23000
= 1 + 10000 / 23000
= 1 + 0.43 (approx).
= 1.43 Years.
Conclusion :- Payback period of investment = 1.43 Years.
