Tip: ROI measures net return as a percentage of the original investment. Use the “Holding Period” field to see your annualised (CAGR-equivalent) rate — useful when comparing investments of different durations.
Our free ROI calculator tells you exactly what percentage return you earned on any investment. Enter your initial and final value, or your total gain and cost — and get your ROI in one click. Add a holding period to see the annualised rate so you can compare investments of different durations side by side.
ROI (%) = (Net Gain ÷ Cost) × 100, where Net Gain = Final Value − Initial Investment. A result above 0% means a profit; below 0% means a loss.
Total ROI is the overall return across the full holding period. Annualised ROI (equivalent to CAGR) expresses what that return would be per year, making it easier to compare a 3-year investment with a 1-year one.
Yes. Switch to 'Gain & Cost' mode and enter your revenue (gain) and spend (cost). The formula is identical — ROI = (Revenue − Cost) ÷ Cost × 100 — whether you're measuring ad campaigns, product launches, or capital projects.
A return multiple of 2× means your investment doubled — you got back twice what you put in, which equals a 100% ROI. A 1× multiple means you broke even (0% ROI).
