Profitability index PI explanation, formula, example, application
Even if the result is greater than 1, you still need to consider other merits (or demerits) of the project before implementing. Consequently, PI’s primary limitation is that it does not consider the full scope of an investment or project. Analysts mitigate this limitation by using PI in tandem with other forms of analyses, such as the net present value (NPV). https://simple-accounting.org/ 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. 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.
This shows that the project will generate value for your business and it can be a good investment. It can be helpful to calculate the net present value prior to calculating the profitability index. But, the profitability index can get calculated using the following profitability index formula(s). The higher a profitability index means a project has benefits and would be considered more attractive. It can be very helpful in ranking potential projects in order to let investors quantify their value. Amidst various analytical tools, the Profitability Index (PI) emerges as a key player.
The Profitability Index (PI) is a ratio of the present value of expected cash flows to the initial investment required for a project. In this article, I will demonstrate the steps to calculate the Profitability Index in Excel. Hopefully, you will find this article helpful before you start any professional project. 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.
The profitability index is calculated as the ratio between the present value of future expected cash flows and the initial amount invested in the project. Let’s assume that the initial investment for expanding a company that sells washing machines is $ 500,000. After five years of the project, cash flows have been discounted at a rate of 10%, and the total present value is $ 800,000.
- The profitability index is also called the benefit-cost ratio for this reason.
- Our comprehensive guide ensures you grasp each nuance, empowering you to make informed financial decisions.
- This process is not just about picking winners; it’s a meticulous evaluation of risks, returns, and the alignment of investments with strategic goals.
- Ascertain whether an investment is viable with computed input of ROI to allow an informed decision on investment management.
- If the present value of expected cash inflows is less than the initial investment, the PI will be less than 1 and negative.
PI ratio compares the present value of future cash flows from an investment against the cost of making that investment. When we talk about the advantages of using this indicator, they are numerous. It is one of the most desirable instructions for performing a budget because, unlike other indicators, it directly indicates the ratio instead of the numbers. Its ease of use helps companies and analysts rank projects according to their (un) cost-effectiveness. When calculating, it considers the time value of money, which clearly shows whether a certain investment will result in a positive or negative value. In contrast, the negative aspects of using PI indicators are that the project’s total size is not taken into account.

The PI ratio will result in a number that is 1, less than 1 or bigger than 1. 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. Here is the final output image after estimating the PV of cash flow for different years for Project B. Our mission is to provide useful online tools to evaluate investment and compare different saving strategies.
Profitability Index Calculation Example #1
First, it is necessary to identify all cash inflows and outflows, determine the discount rate, find the present value of these cash inflows and outflows, and add up all the obtained current values. From this process, we see that the NPV shows us the project’s cost-effectiveness compared to other projects. However, NPV is expressed in monetary units, while PI gives the value ratio.
Does the profitability index consider the time value of money?
The only difference between two is that the NPV shows an absolute value whereas the PI measures the relative value in ratio format. Ascertain whether an investment is viable with computed input of ROI to allow an informed decision on investment management. However, since both PIs are less than 1.0, the company may end up forgoing either project in favor of a better opportunity elsewhere.
Investing in Archer will allow Garch Ltd to earn $80,000 in annual cash flow for the next 5 years. Alternatively, you could calculate it as the ratio of PV to I, so that the PV (Present Value) is divided by the investment. Fundamentally, the Profitability Index shows us the amount of money we earn for every $1 / £1 invested. Prior to accepting a position as the Director of Operations Strategy at DJO Global, Manu was a management consultant with McKinsey & Company in Houston. He served clients, including presenting directly to C-level executives, in digital, strategy, M&A, and operations projects.

What is the difference between NPV and PI?
No matter what kind of business you run or what industry you work in, making a profit is essential to growing and expanding. It is important to understand the benefits you can receive when it comes to projects or possible investments. Using the Profitability Index (PI), you can determine a project’s cost and benefits. The initial investment is the starting point of any project or investment, representing the total of all costs incurred to commence the venture. This can range from purchasing equipment to initial research and development costs.
The profitability index is the ratio between the initial amount invested in a project and the present value of future cash flows. However, as with any analytical tool, the key to harnessing the full potential of the Profitability Index lies in its careful application. Accurate estimation of future cash flows, prudent selection of a discount rate, and thorough consideration of all initial investment costs are critical to deriving a meaningful PI. Moreover, understanding the limitations and context-specific nuances of the PI ensures that it is employed effectively, avoiding the pitfalls of misinterpretation.
Cash flows are discounted the appropriate number of periods to equate future cash flows to current monetary levels. Cash flows received further in the future are therefore considered to have a lower present value than money received closer to the present. The PI is calculated by dividing the present value of the expected cash inflows by the initial investment. If the present value of expected cash inflows is less than the initial investment, the PI will be less than 1 and negative. This indicates that the project is not expected to generate positive returns and may not be worth pursuing. More specifically, the PI ratio compares the present value (PV) of future cash flows received from a project to the initial cash outflow (investment) to fund the project.
The formula used to calculate the PI is the present value of future cash flows divided by the initial amount invested in the project. It is a measure that companies use to determine the cost-benefit ratio before deciding to embark on more complex projects or investments. The Profitability Index (PI) bears an alternative name known by the acronym VIR, which denotes the ratio of investment value or investment to profit.
Therefore, while the PI offers valuable insights for investment decision-making, it should not be the only deciding factor. Another key feature of the PI is its capacity to help businesses understand how changes in essential parameters can affect a project’s profitability. The PI’s main advantage grants, new mexico nm profile lies in its ability to help businesses prioritize projects, especially when resources are scarce. A PI more significant than 1 (like in this example) suggests the project is a good investment. The NPV method reveals exactly how profitable a project will be in comparison to alternatives.
