Step-by-step explanation:
The length of time required to recover the cost of an investment. The payback period of a given investment or project is an important determinant of whether to undertake the position or project, as longer payback periods are typically not desirable for investment positions.
Calculated as:
Payback Period = Cost of Project / Annual Cash Inflows
project payback period if the initial cost is $1,800,
payback period = 2.79 years
project payback period if the initial cost is $3,500,
payback period = 5.43 years
project payback period if the initial cost is $5,300,
payback period = 0 years(never pays back)
