About ROI Calculator

You need a clear answer from the standard formula — not a spreadsheet rabbit hole. ROI Calculator is built for that job: calculate return on investment from amount invested and amount returned.

When the answer looks wrong

Check units first (percents vs decimals, years vs months, currency as plain numbers). Recalculate after fixing inputs. If your real product compounds or adds fees, switch to the matching calculator that models that behavior.

What ROI Calculator computes

Enter the fields on the page and read the result lines. The math follows the standard formula for this roi calculator use case. Treat outputs as planning numbers — they omit taxes, fees, or policy rules unless the on-page notes say otherwise.

Where your data goes

ROI Calculator runs in your browser for this job. Your values is not uploaded to FileToolsHub servers for the conversion itself, which matters when you are dealing with private notes, drafts, or local files.
