Learning how to calculate the return on investment (ROI) for your information technology (IT) systems projects is a financial skill that helps you prove the business case for your idea.
Modeling the ROI on IT investments benefits multiple levels of employees, from entry-level employees to managers and executives. Employees can use ROI projections to justify a project they're interested in pursuing, while an executive can use these calculations to sort through potential projects.
Choosing to pursue one IT project over another can alter the course of your business-you want to ensure you have all the necessary data to make that decision. Calculating the ROI can help.
You can express return on investment as either anticipated or actual. Each serves a different function. Anticipated ROI helps you determine whether a project is worth pursuing, while actual ROI compares whether the completed project is aligned with expectations.
To calculate the ROI of an IT project, you can use this basic formula:

When calculating anticipated ROI, playing with the numbers and running several scenarios is beneficial. Using multiple factors allows you to account for unexpected costs that emerge during development.
With this range of potential outcomes, you can evaluate a project's risk to see if it's truly worth it. The higher the ROI, the more justifiable your project is.
For example, say you have an ROI of 200% over an implementation period of three years. This value means that you'll double your project investment over that period.
If the ROI is minuscule--or even negative--then the business justification for the project isn't there. When considering implementing multiple IT projects or modernizing an old infrastructure, it's worthwhile to determine the ROI for each project and begin with the most profitable.
Categories of IT projects where the ROI formula is beneficial to include:
When calculating an IT project's ROI, you may derive the net profits from one of several categories:

Determining an IT project's ROI also has a few pitfalls to avoid. For example, it's impossible to estimate a project's costs and benefits with a high degree of accuracy in every circumstance. This is why it's imperative to forecast the ROI in several data-based scenarios.
Similarly, a project's expected benefits may result from a combination of planned IT improvements. Be careful to avoid this kind of double counting.
To avoid these pitfalls, your ROI calculations should include the following parameters:
The ROI formula requires determining costs and profits, then comparing a project's ROI in different scenarios.
The cost of a project includes not only the upfront investment but also implementation costs (e.g., project management, software, training, etc.) and operating costs (e.g., cloud services, hardware and licensing).
It's more difficult to forecast profits than to estimate initial costs. Considerations include reduced operating costs, improved software or logistics programs, improved or automated services and improved data entry processes.
Calculate ROI for a project using several different factual scenarios. You might also compare the ROI of different IT projects to prioritize which comes first.
In addition to ROI, other calculations help you make data-based decisions regarding IT projects. Each of these calculations complements the ROI by providing further metrics you can use to select a project.
For example:
