Answer:
5.4 years
Explanation:
In the payback, we analyze in how many years the invested amount is recovered. The computation is shown below:
In year 0 = $1,418,000
In year 1 = $320,000
In year 2 = $280,000
In year 3 = $240,000
In year 4 = $240,000
In year 5 = $240,000
In year 6 = $240,000
In year 7 = $240,000
In year 8 = $240,000
In year 9 = $240,000
In year 10 = $240,000
If we sum the first 5 year cash inflows than it would be $1,320,000
Now we deduct the $1,320,000 from the $1,418,000 , so the amount would be $98,000 as if we added the six year cash inflow so the total amount exceed to the initial investment. So, we deduct it
And, the next year cash inflow is $240,000
So, the payback period equal to
= 5 years + $98,000 ÷ $240,000
= 5.4 years
In 5.4 yeas, the invested amount is recovered.
