Formula Used
The profitability index measures present value created for each invested dollar. It compares discounted future cash inflows with the total initial outlay.
Profitability Index = Present Value of Future Cash Inflows / Initial Outlay
Present Value of Future Cash Inflows = Σ [Cash Flow in Year t / (1 + r)t]
In this calculator, the final year can also include terminal value, salvage value, and recovered working capital. A profitability index above 1.00 usually supports project acceptance, while a value below 1.00 usually signals rejection.
How to Use This Calculator
- Enter the initial investment required for the project.
- Add any working capital tied up at the start.
- Provide the annual discount rate as a percentage.
- Enter yearly net cash inflows for up to eight years.
- Add terminal value, salvage value, and working capital recovery if relevant.
- Set the acceptance threshold and sensitivity step.
- Submit the form to view PI, NPV, payback, yearly analysis, and graph.
- Use the export buttons to save the report in CSV or PDF format.
Why This Metric Matters
Project profitability index helps rank investments when capital is limited. It converts discounted value into a ratio, making comparison across projects easier. Managers often use it with NPV because PI highlights efficiency, while NPV shows absolute value creation. Together they support balanced capital budgeting decisions.
FAQs
1. What does a profitability index above 1 mean?
A value above 1 means discounted inflows exceed the initial outlay. The project creates value on a present value basis and is usually financially acceptable.
2. Is profitability index better than NPV?
They serve different purposes. NPV shows total value added, while PI shows value created per invested dollar. Using both gives better investment decisions.
3. Why use discounted cash flows here?
Discounting accounts for the time value of money. Future cash received later is worth less than cash received today.
4. Should working capital be included?
Yes. Working capital is usually part of the initial outlay. If recovered at the end, include it as a final-year inflow.
5. Can terminal value affect the result a lot?
Yes. A large terminal value can materially raise present value and PI. It should be estimated carefully and consistently.
6. What acceptance threshold should I use?
Most projects use 1.00 as the base threshold. Some firms raise the hurdle when risk, funding limits, or strategic constraints are higher.
7. Why show sensitivity analysis?
Sensitivity testing shows how PI changes when the discount rate moves. It helps identify whether a project stays attractive under tougher assumptions.
8. Can I leave some annual cash flow fields empty?
Yes. Leave unused years as zero. The calculator will still discount each entered value and include terminal adjustments in year eight.
