Answer :
2.25 years
The computation of payback period is shown below:-
Year Cash flows Cumulative Cash flows
0 ($345,000) ($345,000)
1 $220,000 ($125,000)
2 $100,000 ($25,000)
3 $100,000 $75,000
4 $100,000 $175,000
Payback Period
Payback period is defined as the number of years required to recover the original cash investment. In other words, it is the period of time at the end of which a machine, facility, or other investment has produced sufficient net revenue to recover its investment costs.
Payback period = Last period with a negative cumulative cash flow +(Absolute value of cumulative cash flows at that period ÷ Cash flow after that period)
=2 + ($25,000 ÷ $100,000)
= 2.25 years
So, for computing the payback period simply applied the above formula.
