Answer:
3.5 years.
Step-by-step explanation:
Payback period of a project is the time it takes a project it pay back the initial amount that is invested in it. This is an important consideration for investors because it is used to ascertain when investment will return and profits above initial investment can be made.
In this scenario the project has cash flows of $5,000 in year 1, $20,000 in year 2, $15,000 in year 3, and $10,000 in year 4.
For the first 3 years cash flow is 5,000 + 20,000 + 15,000= $40,000
Now we need $5,000 from the fourth year to meet initial investment.
That is $10,000 ÷ 2 or equivalent of half a year in the fourth year.
Therefore it takes 3.5 years for the project to pay back initial investment.
