In financial analysis, the term Profitability Index (PI), also known as Profit Investment Ratio (PIR) or Value Investment Ratio (VIR), is often encountered.

Understanding the Profitability Index

The profitability index (PI) is a financial tool that helps you decide whether an investment is worth making.

How to find profitability index? The PI is calculated by dividing the present value of an investment's future cash flows by its initial cost, thereby offering a ratio that indicates the financial attractiveness and ROI.

The result gives you a "bang for your buck" ratio, telling you how much value you're expected to get out of every dollar invested in a project.

The profitability index (PI) is a better measure of investment value than the payback period because it considers the time value of money. The payback period only tells you how long it takes to get your investment back, but it doesn't tell you how much money you'll make after that.

The PI does this by discounting future cash flows to their present value. This means that it takes into account the fact that money is worth more today than it will be in the future.

The internal rate of return (IRR) is another metric that is often used alongside the profitability index to evaluate investment opportunities.

While the profitability index focuses on the amount of profit a project generates in relation to the initial investment, the IRR looks at the rate of return on that investment over time.

Why is it important? Essentially, the definition of what is profitability index for the business serves as an indicator of the economic viability of a project or investment, allowing for a direct comparison between gains and expenses.

It makes a profitability index a useful tool for ranking projects and selecting which ones to pursue, as well as expecting a good profit for businesses, in the long term.

Calculating the Profitability Index

As mentioned above, the profit index formula is a financial calculation used to determine the profitability of an investment project.

The formula to calculate the profitability index is:

🧮 Profitability Index = Present Value of Future Cash Flows / Initial Investment

Here's a simple example of a Profitability Index calculator. It can be implemented in a spreadsheet like Microsoft Excel or Google Sheets to allow for dynamic calculations.

To calculate the profitability index, we need to determine the present value of the future cash flows using an appropriate discount rate. Let's assume a discount rate of 10% for this example.

In the calculation of the Profitability Index, the Total Discounted Cash Inflows of 3,636.36+4,132.23+2,250.25+1,527.78+620.92=12,167.54 is divided by the Initial Investment Cost of 10,000

Profitability Index

1.2168

As the table shows, it results in a Profitability Index of 1.2168, suggesting that the investment is profitable.

Another formula that can be used for calculating the profitability index is as follows:

🧮 Profitability Index = (Net Present Value + Initial Investment) / Initial Investment

This formula takes a slightly different approach: in this version, the formula adds the Net Present Value (NPV) of an investment to its initial investment and then divides the sum by the initial investment.

For both formulas, a value greater than 1 indicates a positive net present value, and, thus, a potentially profitable project.

Let's say a company is considering a new project that requires an initial investment of $10,000. The project is expected to generate the following cash inflows over the next 5 years:

The company uses a discount rate of 10% to discount these future cash inflows.

First, calculate the Net Present Value (NPV) using the discounted cash flows. For this example, the NPV is $2,167.54.

Now, to calculate the Profitability Index (PI).

PI=(NPV+Initial Investment):Initial Investment​=(2,167.54+10,000):​10,000​ =1.2168

In this specific example, the PI is 1.2168, which is greater than 1. Based on this financial metric, it suggests a good investment opportunity,

Choosing Between Present Value and Net Present Value in Profitability Index Calculations

Present Value is a concept that calculates the current value of a future sum of money, taking into account a specific discount rate and is commonly used to assess the worth of individual cash flows or a sequence of cash flows occurring at different time points.

The net present value (NPV) of a project or investment is the sum of the present values of all future cash flows, minus the initial investment. It is primarily used for evaluating the profitability of an investment or a project as a whole.

When to use PV in calculating profitability index:

  • To calculate the profitability index of a single cash flow.
  • To calculate the profitability index of a project or investment with a single cash flow.

When to use NPV in calculating profitability index:

  • To calculate the profitability index of a project or investment with multiple cash flows.
  • To compare the profitability of multiple projects or investments.

Example:

Suppose we are considering a project with an initial investment of $100,000 and the following expected future cash flows:

Year 1: $20,000
Year 2: $30,000
Year 3: $40,000

To calculate the profitability index using PV, we would first need to calculate the PV of each cash flow. Using a discount rate of 10%, the PV of the cash flows is as follows:

Year 1: $18,181.82
Year 2: $25,720.59
Year 3: $30,831.82

The profitability index of the project would then be calculated as follows:

Profitability Index = (PV of Year 1 Cash Flow + PV of Year 2 Cash Flow + PV of Year 3 Cash Flow) / Initial Investment

Profitability Index = ($18,181.82 + $25,720.59 + $30,831.82) / $100,000
Profitability Index = 1.747423

This indicates that the project is expected to generate a profit of $74,742.30.

To calculate the profitability index using NPV, we would simply sum the PV of all future cash flows and subtract the initial investment.

Profitability Index = Net Present Value / Initial Investment
Profitability Index = $74,742.30 / $100,000
Profitability Index = 1.747423

As you can see, the profitability index is the same regardless of whether you use PV or NPV. However, NPV is more commonly used for projects with multiple cash flows.

The Bottom Line: The Present Value (PV) method is used to calculate the Profitability Index (PI) when the investment generates a stream of cash flows that are equal in amount and equally spaced in time.

On the other hand, the Net Present Value (NPV) method is used to calculate the PI when the cash flows generated by the investment are not equal in amount or equally spaced in time.

How PI is used in business decision-making

The PI can provide valuable insights into the financial viability of a project and guide business decisions by providing multiple benefits.

Capital Budgeting: Companies use the profitability index to determine which projects will generate the highest return on investment and allocate their limited capital resources accordingly.

Identify and rank profitable projects: The Profitability Index (PI) serves as a valuable tool for enterprises to discern the relative profitability of various projects.

Make investment decisions: By aiding in the identification and selection of the most lucrative investment opportunities, the PI can be regarded as a comparative metric for more confidence in investment-related decisions.

Evaluate the performance of investments: The PI can be used to evaluate the performance of investments by comparing the PI of the actual investment to the PI of the expected investment. This can help businesses to identify investments that are underperforming.

Business Expansion: When considering expanding their operations or entering new markets, companies can use the profitability index to evaluate the profitability of such ventures.

Here is an example of how the PI can be used in business decision-making.

A company is considering two investment projects.

Project A: Initial investment of $100,000, expected future cash flows of $20,000 per year for 5 years.

Project B: Initial investment of $50,000, expected future cash flows of $10,000 per year for 5 years.

Using a discount rate of 10%, the PI of each project is as follows:

Project A: PI = 1.58

Project B: PI = 1.24

Based on the PI, Project A is more profitable than Project B.

Therefore, the company would likely invest in Project A.

Side note: It is important to remember the limitations of the profitability index calculations. In particular, it relies on estimated future cash flows, which are subject to uncertainty and potential errors.

In the context of calculating the Profitability Index (PI), the time horizon also plays an important role, as it determines the span over which future cash flows are discounted back to their present value.

Therefore, the PI is just one of many factors that businesses should consider when making investment decisions. Other factors, such as the riskiness of the project, the company's strategic goals, and the availability of resources, should also be taken into account.

Interpreting the Profitability Index

In financial analysis, the interpretation of the Profitability Index plays a vital role in evaluating the desirability of an investment or project.

What is a good profitability index?

PI > 1
Think of it like a financial scoreboard: a score above 1 means you're winning, raking in more value than you're putting in. Hence, a profitability index greater than 1 indicates that the project is expected to generate more value than the initial investment.

The Outcome: The project is financially viable and should be pursued.

The higher the PI, the more profitable the project is expected to be. A PI of 2, for example, suggests that the project is expected to generate twice the value of the initial investment.

PI < 1
A profitability index of less than 1 indicates that the project is expected to generate less value than the initial investment.

The Outcome: In such cases, the project is considered financially unviable, and it may be advisable to abandon or reject the project. (A PI of 0.5, for example, suggests that the project is expected to generate only half the value of the initial investment, making it economically undesirable).

PI = 1
A profitability index equal to 1 indicates that the project is expected to generate exactly the same value as the initial investment.

The Outcome: In this case, the project is considered to be at the breakeven point. While it may not result in a significant profit, it also does not lead to a loss. The decision to proceed with such a project would depend on other factors, such as the strategic importance or non-financial benefits associated with the project.
