Cost Benefit Analysis Calculator Spreadsheet
Cost Benefit Analysis (CBA) is a systematic approach to evaluating the pros and cons of a project, policy, program, or investment. It’s crucial for making informed decisions by quantifying and comparing the expected costs and benefits of different options.
How to Use This Calculator
- Enter the initial cost of the project.

Formula & Methodology
The calculator uses the net present value (NPV) formula to determine the present value of future cash flows. The formula is:
NPV = ∑ [CFt / (1 + r)^t] – Initial Cost
where CFt is the net cash flow in year t, r is the discount rate, and t is the number of years.
