Investors should use the profitability index in conjunction with other investment appraisal methods. The higher the PI ratio, the more attractive the proposed project is and the more likely it will be pursued. For example, if a project costs $1,000 and will return $1,200, it’s a “go.” As now you also know how to calculate profitability index in excel, you can use it on your own.

• Generally, you should prefer the project with the highest PI and the highest IRR, as it means that it creates the most value per unit of capital invested and offers the highest return on investment.
• Another variation of the PI formula adds the initial investment to the net present value (NPV), which is then divided by the initial investment.
• It’s a popular calculation used to evaluate investments, and is sometimes also known as cost-benefit ratio, benefit-cost ratio, or capital rationing.
• If you don’t fancy calculating the present value manually, you can use the present value calculator here.

It is sometimes known as value investment ratio (VIR) or profit investment ratio (PIR). It is used to evaluate the potential of a company to generate profit from an investment. The cost of funding the project is $10 million, and the amount of cash flows generated in Year 1 is $2 million, which will grow by a growth rate of 25% each year. With that said, for purposes of presenting a project or capital investment’s benefits on a per-dollar basis of the initial investment, the profitability index is more practical since it is standardized.

How to Find Profitability Index

The profitability index is calculated by dividing the cash inflow and the cash outflow’s… However, sometimes the PI and the IRR may give conflicting results, especially when there are multiple cash flows with different signs or timing. For example, a project may have a high IRR but a low PI, or vice versa.

You can calculate it by dividing the present value  of the project’s expected cash flows by the present value of the capital investments. The Profitability Index (PI) measures the ratio between the present value of future cash flows and the initial investment. The index is a useful tool for ranking investment projects and showing the value created per unit of investment.

What is the internal rate of return (IRR)?

If the result is greater than 1.0, investors will likely go on to consider the other merits of the project. If the profitability index of a project is 1.2, for example, investors would expect a return of $1.20 for every $1.00 spent on funding the project. The profitability index is used for comparison and contrast when a company has several investments and projects it is considering undertaking. The PI is especially useful when a company has limited resources and can’t pursue all potential projects, as it can be used to prioritize which projects to pursue first. The index can be used alongside other metrics to determine which is the best investment. The PI and the IRR can help you decide whether to accept or reject a project based on a given hurdle rate, which is the minimum required return on investment.

The Profitability Index (PI) or profit investment ratio (PIR) is a widely used measure for evaluating viability and profitability of an investment project. It is calculated by dividing the present value of future cash flows by the initial amount invested. If the profitability index is greater than or equal to 1, it is termed a good and acceptable investment. The profitability index is a calculation determined by dividing the present value of futures cash flows by the initial investment in the project. The initial investment is the amount of capital required to start the project.

Profitability Index Formula

If a project has a PI greater than 1, you should invest in the project. The profitability index method measures the acceptability of a project through the ratio of the projected cash inflow to the initial investment. Learn about the definition and calculation of profitability index and understand how to interpret its results. Let us say that we are examining a project, which requires an initial investment of $10,000, and after the will give us cash flow of $3,000, $4,000, $2,000, 41,500, and $1,800 in the next five years. The initial investment is negative because the first cash flow is going out.

The profitability index is calculated by dividing the present value of future cash flows that will be generated by the project by the initial cost of the project. The profitability index is an appraisal technique applied to potential capital outlays. The method divides the projected profitability index formula capital inflow by the projected capital outflow to determine the profitability of a project. As indicated by the aforementioned formula, the profitability index uses the present value of future cash flows and the initial investment to represent the aforementioned variables.

Investment Required (Denominator)

When weighing several positive NPV options, the ones with the higher discounted values should be accepted. Where PV is the present value, CF is the cash flow in a given year, r is the discount rate, and n is the number of years. The profitability index is also called the benefit-cost ratio for this reason.

A less than 1 PI ratio means that the project’s present value would not recover its initial investment or cost. Theoretically, it reveals unprofitability of a proposed investment and suggests rejection of the same. In general terms, the higher the PI metric, the more attractive a proposed investment is. It’s important to note that one problem with using the profitability index is that it does not allow a business owner to consider the full scope of the project.
