ROI

ROI — Return on Investment (ROI) is a measure of how much profit or value you gain from money or resources you invest in something.

In simple English

In business and tech, ROI measures the financial return generated relative to the cost of an investment. For example, if your company spends $100,000 on a new software platform and it saves $250,000 per year, the ROI is positive. In tech companies, managers and executives use ROI to decide whether to fund projects, hire teams, or adopt new technologies. Non-technical professionals often ask engineers about ROI to understand if a technical investment makes business sense. You will hear this term in budget meetings, stakeholder presentations, and strategic planning discussions.

How to say it: Spell it out: R-O-I ("ar-oh-eye").

Real examples(3)

  • in a budget meeting

    "The CFO asked about the ROI of automating our testing pipeline before approving the budget."

  • in a project proposal

  • in a standup

    "The infrastructure redesign has a strong ROI because it reduces cloud costs by 40 percent."

More mistakes(2)

Handle with care. ROI is about financial return, not code review or technical improvement. Do not use it to mean review or inspection of code.

  • ✕The ROI shows the code quality is bad.
    ✓The metrics show the code quality is bad.

    ROI measures financial return only, not technical quality. Use metrics, analysis, or audit.

  • ✕We improved the ROI by fixing bugs.
    ✓We improved the product by fixing bugs, which should increase ROI over time.

    Bug fixes improve the product, but ROI is calculated separately. Connect the action to financial impact.
