(A) CalculatingPayback Period:

Year

Annual Cash Flows

Net Cash flows

0 ($32,500) ($32,500) 1 $12,000 ($20,500) 2 $12,000 ($8,500) 3 $12,000 4 $12,000 5

$12,000 + $5,000

Payback Period = {Last yearwith a negative NCF} + {Absolute value of NCF in that year / TotalCash flow in the following year} Payback Period =2 + [$8,500 /$12,000] Payback Period = 2 + 0.708 Payback Period = 2.71years (B) Calculating DiscountedPayback Period, if interest rate is 14%:
