Profitability Index PI Rule: Definition, Uses, and Calculation

It ensures that capital is committed to the best investment option for maximum profit when considering multiple choices. You can use a profitability index template or table like the one below to plug in your values. A PI template helps give a visual representation of the present value of future cash flows in order to calculate your project’s PI. All one needs to do is to find out the present value of future cash flows and then divide it by the initial investment of the project. The profitability index is the ratio between the present value of future expected cash flows and the initial amount invested in the project.

It represents the economic order quantity formula assumes that the relationship that exists between the costs and the benefits of a potential project. The profitability index is the ratio between the initial amount invested in a project and the present value of future cash flows. The profitability index formula is used calculate the profitability of a project based on its future discounted returns relative to the initial investment. The PV of future cash flows does not include the initial investment. Hence, it is also known as the profit investment ratio (PIR), value investment ratio (VIR), or benefit-cost ratio (BCR).

As they are considering whether it’s a good deal to invest in, they have found out that the present value of the future cash flow of this project is 130 million. The factory expansion project has a higher profitability index and a more attractive investment. The company might decide to pursue this project instead of the new factory project because it is expected to generate more value per unit of investment.

1. The profitability index measures the present value of future expected cash flows and the initial amount invested in a project.
2. Keep in mind that if the profitability index is less than 1, this does not necessarily mean that the cash flows will add up to less than the initial outflow.
3. To find more attractive investments, look for a profitability index that is the highest.
4. A profitability index of 1.0 is the lowest acceptable measure on the index.
5. It doesn’t matter the type of business that you operate or the industry that you are in.
6. Notwithstanding, when comparing the attractiveness of different independent projects, to maximize limited financial resources, you must accept the project with the highest PI.

In that case, the company should invest in a project that has more PI than this particular project. The best thing about this index is that it allows businesses to compare between different projects whenever they require choosing one out of the other. The projects having more chances of generating profits is the project that the firms are likely to choose.

It also doesn’t matter if you’re a sole trader or a limited liability partnership. Generating profit and increasing that profit margin is the difference between keeping your doors open or closed. Using the PI formula, Company A should do Project A. Project A creates value – Every $1 invested in the project generates $.0684 in additional value. As the value of the profitability index increases, so does the financial attractiveness of the proposed project.

Calculations less than 1.0 indicate the deficit of the outflows is greater than the discounted inflows, and the project should not be accepted. But we know that the project with a lower upfront amount is a far better investment. Thus, we need their PI values, which reflect this vital information such that the lower upfront investment has a PI of 2.00 while the higher upfront investment has a PI of 1.01. The profitability index calculator is a great tool to help you analyze your options. The profitability index helps compare and contrast investments and projects a company is considering. The PI is especially useful when a company has limited resources and can’t pursue all potential projects.

When weighing several positive NPV options, the ones with the higher discounted values should be accepted. As mentioned above, having a profitability index higher than 1 is ideal. If this happens, it shows that the project will most likely break even.

The profitability index can help you determine the costs and benefits of a potential project or investment. It’s calculated based on the ratio between the present value of future cash flows and the initial investment. You need to consider initial investment, the rate of return and future cash flows. The profitability index measures whether or not a project or investment will benefit your business.

The index is a useful tool for ranking investment projects and showing the value created per unit of investment. Obviously, an investor wants the present value of future cash flows to be higher than their initial investment. Keep in mind that if the profitability index is less than 1, this does not necessarily mean that the cash flows will add up to less than the initial outflow.

Understanding the Profitability Index Rule

It may only mean that the rate of return is less than the discount rate used when calculating the present value of the cash flows. The profitability index is used as an appraisal technique for potential capital outlays. However, the PI disregards project size when comparing project attractiveness.

Profitability index helps businesses assess their ability to make money and this is what makes it one of the most important metrics for estimating profits over a period efficiently. However, even if the PI is widely used for doing cost-benefit analyses, it is not free of demerits. As every good side has its limitations, PI also has a couple of limitations. However, there is another way through which we can express PI, and that is through net present value. NPV method is a good measure as well to consider whether any investment is profitable or not. The profitability index rule is a variation of the net present value (NPV) rule.

PI is very similar to the concept of net present value (NPV), but there are a few differences. Generally speaking, a positive NPV will correspond with a PI greater than one, while a negative NPV will track with a PI below one. If we compare both of these formulas, they both will give the same result. The higher the profitability index, the more attractive the investment. However, both PIs are xero security report and data breaches less than 1.0, so the company may forgo either project.
