Answer:
NPV of Project A = $1,023,425 +$5,640 - $520,000 = $509,065
NPV of Project B= $560,175 + $9,320 - $380,000 = $189,495
Explanation:
Net Present Value = Present value of cash inflows - Present value of cash outflow
For project A
Annual cash inflow = After tax income + Depreciation
= $150,000 + ($520,000 - $10,000)/6 = $150,000 + $85,000 = $235,000
Present value of out flow = $520,000
Present value of inflows = PVAF 10%, 6 years = 4.355 X $235,000 = $1,023,425
Present value of Salvage = PVIF 10%, 6th year = 0.564 X $10,000 = $5,640
NPV of Project A = $1,023,425 +$5,640 - $520,000 = $509,065
For project B
Annual cash inflow = After tax income + Depreciation
= $60,000 + ($380,000 - $20,000)/8 = $60,000 + $45,000 = $105,000
Present value of out flow = $380,000
Present value of inflows = PVAF 10%, 8 years = 5.335 X $105,000 =$560,175
Present value of Salvage = PVIF 10%, 8 = 0.466 X $20,000 = $9,320
NPV of Project B= $560,175 + $9,320 - $380,000 = $189,495
NPV of Project A = $1,023,425 +$5,640 - $520,000 = $509,065
NPV of Project B= $560,175 + $9,320 - $380,000 = $189,495
