Answer:
1) depreciation expense per year = $146,500
2) net income:
years 1 - 4 = $149,450
net cash flows:
year 0 = -$620,000
year 1 = $295,950
year 2 = $295,950
year 3 = $295,950
year 4 = $329,950
3) payback period = 2.09 years
4) accounting rate of return = 24.1%
5) net present value (NPV) = $483,330.83
Step-by-step explanation:
purchase cost of the machine $620,000
depreciation expense per year = ($620,000 - $34,000) / 4 = $146,500
expected annual sales $2,190,000
direct materials $494,000
direct labor $686,000
overhead (excluding depreciation) $476,000
S&A expenses $174,000
total costs (excluding depreciation) = $1,830,000
income taxes 30%
net income per year = ($2,190,000 - $1,830,000 - $146,500) x 70% = $149,450
net cash flow (years 1 - 3) = $149,450 + $146,500 = $295,950
net cash flow (year 4) = $149,450 + $146,500 + $34,000 = $329,950
payback period = $620,000 / $295,950 = 2.09 years
accounting rate of return = $149,450 / $620,000 = 24.1%
NPV, using a financial calculator = $483,330.83
