Profitability Index = (Net Present value + Initial investment) / Initial investment….Project A needs an initial investment of $2,000,000 and a discount rate of 10% and with estimated annual cash flows of:
- $300,000 in Year 1.
- $600,000 in Year 2.
- $900,000 in Year 3.
- $700,000 in Year 4.
- $600,000 in Year 5.
What is the profitability index for project B?
We need to calculate the net present value added by each project per $1 of initial investment i.e. their profitability index….Solution.
| Project | Profitability Index | |
|---|---|---|
| B | 1 + 15/50 | = 1.30 |
| C | 1 + 10/10 | = 2.00 |
| D | 1 + 20/60 | = 1.33 |
| E | 1 + 12/35 | = 1.34 |
How do you measure profitability of a project?
The profitability index is calculated by dividing the present value of future cash flows by the initial cost (or initial investment) of the project. The initial costs include the cash flow required to get the team and project off the ground.
How do you compute IRR?
It is calculated by taking the difference between the current or expected future value and the original beginning value, divided by the original value and multiplied by 100.

The Profitability Index is also known as the Profit Investment Ratio (PIR) or the Value Investment Ratio (VIR).
How is profitability index related to present value of cash flows?
