Answer:
3.08 years
Step-by-step explanation:
The computation of payback period is shown below:-
Payback period = Year up to which cumulative cash flow are negative + (Cumulative cash flow in period in A ÷ cash flow of immediately year succeeding the period in A )
Year Cash flow cumulative cash flow
0 ($180,000) ($180,000)
1 $60,000 ($120,000)
($180,000 - $60,000)
2 $40,000 ($80,000)
($120,000 - $40,000)
3 $70,000 ($10,000)
($80,000 - $70,000)
4 $125,000 $115,000
(it will be end here because it excess from here)
Now we will put it into formula
Pay back period = 3 + (10,000 ÷ 125,000)
= 3 + 0.08
= 3.08 years
