Profitability index PI explanation, formula, example, application

Secondly, as a relative metric, it becomes beneficial in contrasting projects of varying magnitudes. While the PI plays a vital role in the decision-making procedure, 4 tips for becoming an independent contractor it still needs to eliminate the necessity for a comprehensive analysis. However, if they are added together, the sum total is larger than project 1’s NPV.

And lastly, investing in Catcher will earn Garch Ltd $155,000 in annual cash flow for the next 5 years. This is the present value of the future cash flow that you’re earning, for every pound you’ve invested. The PI is especially beneficial when limited funds constrain capital budgeting decisions. The PI is more than a simple binary indicator; it also aids in comparing multiple projects. The project boasting the highest PI could be deemed the most appealing investment as it offers the highest return relative to its cost.

Using the equation above, we can calculate the profitability index as 1.269 for Project Y and 1.232 for Project Z. Treat the profitability index as a helpful guideline, but always use it in tandem with the net present value method and other forms of multifaceted analysis. If any part of the profitability index formula isn’t quite clear, please re-read this article. Furthermore, you learned that there are 2 ways to calculate the PI, including one where we take the ratio of NPV to I, and another, where we take it as the ratio of PV to I.

Therefore, the formula divides the present value (PV) of the project’s future cash flows by the initial investment. The profitability index is helpful in ranking various projects because it lets investors quantify the value created per each investment unit. As the value of the profitability index increases, so does the financial attractiveness of the proposed project. Running a profitable business demands a lot of investments and assessing them for profitability is essential. The profitability index (PI), also known as profit investment ratio (PIR) is a method to describe the relationship between cost and benefits of a project.

Because the NPV / I approach shows us exactly how much money we make for every pound we invest. Put differently, you earn a 10th (1/10) of what Project A is offering you on a per pound invested basis. Well, it just means that for every £1 pound you invest in Project A, you earn 50p. This shows you how much money you make for every one dollar or one pound you invest. The key takeaway here is that you can invest 1% of the requirement of Project B, by investing in Project A, and earn a higher Net Present Value per pound/dollar invested. With NPV of £10,000 and £100,000, and investments of £20,000 and £2 million, that means that the Present Value (PV) of Projects A and B equates to £30,000 and £2.1 million pounds.

Another variation of the PI formula adds the initial investment to the net present value (NPV), which is then divided by the initial investment. 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. Generally the PI ratio of 1 is least acceptable as it represents the break even point of a project, which defines the point where total sales (revenue) equal to the total cost. A PI ratio of less than 1 is completely undesirable as it represents that a project will cost more than it is expected to earn. The advantage of the profitability index method is that it mathematically leads to the same decision for independent projects as the NPV method.

The profitability index is a calculation determined by dividing the present value of futures cash flows by the initial investment in the project. 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.

When assessing a possible investment’s viability, the profitability index is particularly beneficial for two main reasons. Suppose further that the company has only $40,000 available to invest and all the projects are independent, not mutually exclusive. Because of cash constraint, It can’t undertake both project 1 and another from project 2 and 3.

Understanding the Profitability Index (PI)

These additional capital outlays may factor in benefits relating to taxation or depreciation. It may not always indicate the correct decision when ranking projects but would certainly provide an insight into the cost-benefit efficiency of one monetary unit invested. Despite its relevance, this index uses just an estimate of the cost of capital in its calculation, so it should not be reviewed on a stand-alone basis. Combined with the Payback Period, Discounted Payback Period, and the Accounting Rate of Return, this ratio provides meaningful data to work with.

Profitability Index Calculation Example (PI)

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. Using the net present value method of evaluating investment projects helps mitigate this problem, but raises other details worth considering. Certainly, the time a project requires to become profitable is a persistent concern for investors, and market factors can elongate the time table in unpredictable ways. In capital-constrained situations, organizations must invest in projects that promise the highest returns per unit of investment. Projects with a higher PI are typically preferred as they deliver more value for each dollar spent. The PI is most effective when a project’s cash flow pattern is conventional, meaning that a series of inflows follow an initial outlay.

To build solid decision-making criteria for investments, we often combine it with other ratios. Assuming that the cash flow calculated does not include the investment made in the project, a profitability index of 1 indicates break-even. Any value lower than one would indicate that the project’s present value (PV) is less than the initial investment. As the value of the profitability index increases, so does the financial attractiveness of the proposed project. The profitability index (PI) is a tool to measure the monetary benefits (i.e. cash inflows) received for each dollar invested (i.e. cash outflow), with the cash flows discounted back to the present date.

The net present value method will lead to the same decision because the NVP of Project Y of $5,386,887.43 is greater than the NPV of Project Z of $4,643,147.49. There are two different calculations that you can use to determine the profitability index. If for whatever reason, Garch Ltd can’t find anything else to invest in, and the risk-free rate is lower than say inflation, then they should probably go ahead and invest in Catcher. The problem is that this doesn’t factor in the magnitude of the investment requirement. Consider that we tell you there are two projects, which we’ll conveniently call Project A and Project B.

The profitability index (PI) is a measure of the attractiveness of a project or investment. It is calculated by dividing the present value of future expected cash flows by the initial investment amount in the project. A PI greater than 1.0 is considered to be a good investment, with higher values corresponding to more attractive projects. Under capital constraints and when comparing mutually exclusive projects, only those with the highest PIs should be undertaken.

Other names used for are the value investment ratio (VIR) and the profit investment ratio (PIR). 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. If the outcome of the ratio is greater than 1.0, this means that the present value of future cash flows to be derived from the project is greater than the amount of the initial investment. At least from a financial perspective, a score greater than 1.0 indicates that an investment should be made. As the score increases above 1.0, so too does the attractiveness of the investment. The ratio could be used to develop a ranking of projects, to determine the order in which available funds will be allocated to them.

And depending on the risk-free rate (typically the yield on U.S. Government Bonds), Garch Ltd should either deposit the remaining $50,000 and earn the risk-free rate. And lastly, similar story for Catcher; we expect to earn $0.02 for every $1 invested. If we think about Brochure, for instance, the 18 cents means that for every $1 we invest in brochure, we expect to earn 18 cents. The projects are divisible, meaning Garch Ltd can invest in parts of a project instead of having to invest fully in a given project.

Moreover, PI might not be the best tool for mutually exclusive projects with different sizes and timing of cash flows. The computation of PI necessitates the initial determination of the present value of projected cash inflows. This step involves applying a discount rate – usually the cost of capital attributed to the project – to every future cash inflow. The profitability index (PI), often referred to as the profit investment ratio or value investment ratio, serves as an essential tool in capital budgeting used to assess prospective investments or initiatives.
