Modified economic feasibility analysis for customer tracking system:
Monetary benefits of an information system = $50,000 per year.
One-time costs = $47,500
Recurring cost = $32,000 per year.
Discount rate = 10%
Time period = 5 years
Present value for benefits and costs can be calculated by using the formula:
Here, PVn is the present value and i is the discount rate.
Present value (PV) calculation for benefits:
Benefits starts from year 1, hence calculation of present value starts from year 1.
Net Present Value (NPV) for benefits:
Present Value (PV) for costs:

Explanation of Solution
Modified Economic Feasibility Analysis for Customer Tracking System at discount rate(12%):
Monetary benefits of an information system = $50,000 per year.
One-time costs = $47,500
Recurring cost = $32,000 per year.
Discount rate = 12%
Time period = 5 years
Present value for benefits and costs can be calculated by using the formula:
Here PVn is the present value and i is the discount rate.
Present value (PV) calculation for benefits:
Benefits starts from year 1, hence calculation of present value starts from year 1.
Net Present Value (NPV) for benefits:
Present Value (PV) for costs:
Net Present Value (NPV) for costs:
Overall Return on Investment (ROI):
Overall return on investment can be calculated as:
Break-Even Analysis (BEA):
- Break even analysis is carried out by determining NPV of yearly cash flows.
- The yearly cash flows are calculated by subtracting present values of recurring costs from the present value of yearly benefits.
- The overall NPV cash flow is total cash flow of the preceding years.
- After determining NPV yearly cash flows, it is found that break even occurs between years three and four
