Explanation:
Payback calculates the amount of time it takes to recover the amount invested in a project from it cumulative cash flows
Payback period = Amount invested / cash flow
Cash flow = profit after tax + depreciation
Straight line depreciation expense = (Cost of asset - Salvage value) / useful life
(300,000 - 0) / 5 = $60,000
Profit after tax = (1 - tax rate) x (sales - expenses - depreciation)
0.6 x ($200,000 - $80,000 - $60,000) = $36,000
Cash flow = $36,000 + 60,000 = 96,000
Payback period = $300,000 / $96,000 = 3.1 years
