Calculating the return on investment
of an AI project

An AI project is defended with numbers, not promises. This guide gives the method to calculate return on investment, the gains and costs to include, a realistic order of magnitude, and how to present it to an executive committee.

How do you calculate the ROI of an AI project?

The return on investment of an AI project uses a simple formula: ROI = (gains − costs) / costs × 100. Gains group time saved, costs avoided and revenue generated; costs cover the whole investment. A positive ROI means the project returns more than it costs.
Worked example (illustrative)
Time saved (2 h/person/week × 20 people × hourly cost)+ €120,000/yr
Costs avoided (errors, outsourcing)+ €30,000/yr
Project cost (build + year-1 running)− €60,000
Return on investment (year 1)+ 150%
Example values. The interactive calculator will be embedded on the page.

Which gains should you count?

Count four kinds of gains: time saved by teams, costs avoided (errors, rework, outsourcing), revenue generated (sales, retention, responsiveness), and quality gains that are hard to price but real. The first two are the easiest to measure and often enough to justify a first project.

Which costs should you include?

Include all costs, not just technology: the human work of scoping and development, data, licences and hosting, then ongoing running (maintenance, monitoring, training). Forgetting recurring costs is the mistake that most distorts profitability calculations.

For detailed ranges, see the guide "How much does an AI project cost".

What ROI should you expect from an AI project in an SME?

A well-scoped AI project aims for a positive return within the first year. The scale depends on the use case: automating repetitive tasks pays back quickly, while a more structural project takes longer. The useful rule is to aim for a fast measurable gain rather than a high theoretical return.

How do you prove ROI to your executive committee?

You prove an ROI by tying it to a clear perimeter, a horizon and a source for each figure. An executive committee does not want a flattering percentage, but a traceable reasoning: here is the assumption, here is the measurement, here is the result. Credibility comes from method, not optimism.
At YPrtnrs, the cockpit "ROI and finance" view calculates this return live and presents it from three angles (pilot, portfolio, five years). Each figure carries its perimeter and source, as in the Blueprint financial model. Y sums it up in one sentence for the committee.

Over what period should you measure ROI?

Measure return on investment over three complementary horizons: the pilot (the first 90 days), the portfolio (all initiatives over the year) and the long term (three to five years). The first proves value, the second scales it, the third projects it. A single horizon gives a partial view.

Frequently asked questions

What is the ROI formula?

ROI = (gains − costs) / costs × 100. Gains include time saved, costs avoided and revenue generated; costs cover the whole investment, including running.

Can you quantify qualitative gains?

Partly. Quality, satisfaction or responsiveness often translate into costs avoided or revenue. What cannot be quantified is documented, without inflating the calculation.

Do you need a positive ROI in the first year?

That is the goal of a well-scoped project. Some structural initiatives take longer; what matters is a first measurable gain that justifies the rest.
