Answer:
The payback period for even cash flow is 4 years
The payback period for uneven cash flows is 5 years
Step-by-step explanation:
The payback period is a term used in capital budgeting and is one of the ways of assessing a project. It calculates the time required to recover the total cost invested in the project initially.
Payback period for Even cash flows
Payback period = Number of years till last period + Unrecovered cost at the beginning of the last period for payback / Total cash flows during the last period
The last period here refers to the period in which the cost will be recovered.
The initial cost is $1200000
Recovery till last year of payback = 300000 + 300000 + 300000 = $900000
Payback period = 3 + 300000 / 300000 = 4 years
Payback under uneven cash flows
Initial cost = $1200000
Recovery till last year of payback = 150000 + 150000 + 400000 +400000 = 1100000
Payback period = 4 + 100000 / 100000 = 5 years
