Answer:
5 years
Explanation:
The Cash payback period is the period taken for the cumulative inflows from an investment to be equivalent to the amount invested.
Using the table below,
Period Cash outflows Cash inflows Cumulative Balance
Year 0 (500,000.00) - (500,000.00)
Year 1 - 120,000.00 (380,000.00)
Year 2 - 110,000.00 (270,000.00)
Year 3 - 110,000.00 (160,000.00)
Year 4 - 100,000.00 (60,000.00)
Year 5 - 60,000.00 -
Year 6 - 60,000.00 60,000.00
Year 7 - 60,000.00 120,000.00
Year 8 - 60,000.00 180,000.00
From the table above, the cumulative balance is nil at year 5. Hence the payback period is 5 years.
