ROI

What is ROI?

ROI, or return on investment, is a ratio that measures how much value an investment generates relative to what it cost. It is one of the most widely used ways to judge whether a spend was worthwhile, and it lets very different initiatives (a marketing campaign, a new tool, a website redesign) be compared on the same basis.

How to calculate ROI

The standard formula is: ROI = (net return − cost) / cost × 100, expressed as a percentage. If you invest €10,000 and earn €15,000 back, the net return is €5,000 and the ROI is 50%. A positive ROI means the investment created value; a negative ROI means it lost money.

Why ROI matters

ROI turns a decision into a number that anyone can weigh. It helps prioritise where to put limited budget, justifies spending to stakeholders, and provides a shared yardstick across teams. Because it is expressed as a ratio, it works whether you are comparing a €500 or a €500,000 project.

Limits of ROI

ROI is powerful but incomplete. It ignores time (a 50% return in one month is very different from 50% over five years) and it struggles with benefits that are hard to quantify, such as brand awareness or customer trust. It also depends entirely on how honestly costs and returns are measured. For time-sensitive decisions, related measures like annualised ROI or payback period give a fuller picture.

ROI in marketing and web projects

Digital work is often judged on ROI: the return on ad spend, the value of organic traffic against the cost of content, or the payback of a website rebuild through higher conversion. Defining what counts as "return" up front (leads, revenue, time saved) is what makes the figure meaningful rather than arbitrary.
