Answer:
Payback period = 4 years 11.72 months
Step-by-step explanation:
The payback period is the estimated length of time in years it takes
the net cash inflow from a project to equate and recoup the the initial cost
Where a project is expected to generate a series of equal annual net cash inflow, the payback period can be calculated as:
Payback period =The initial invest /Net cash inflow per year
Payback period for project X
Cumulative net cash inflow for 4 years
=$2,140,000× 4 = $8,560,000
Cash in flow in year 5 = annual cash inflow + scrap value
2,140,000 + 50,000= $2,190,000
Payback period = 4 years + (10,700,000-8,560,000 )/2,190,000 × 12 months
= 4 years 11.72 months
Payback period for project X= 4 years 11.72 months
