Measure total return on investment and, when a duration is provided, compare it with an annualized compounded rate.
ROI = (Returned − Invested) ÷ Invested × 100Calculate ROI percentage, net gain or loss and optional annualized ROI from an initial amount, returned value and holding period.
ROI measures net gain or loss relative to the amount originally invested. Toolmera calculates Net Gain = Amount Returned − Amount Invested, then ROI = Net Gain ÷ Amount Invested × 100.
A positive result represents a gain relative to the starting cost; a negative result represents a loss.
Simple ROI ignores how long the result took to achieve. A 50% gain over one year and a 50% gain over ten years have the same simple ROI even though their annualized growth rates are very different.
When a positive duration and positive ending value are provided, Toolmera also shows the compounded annualized rate implied by the start and end values.
ROI can be used for investments, business projects or marketing spend, but the quality of the result depends on what you include in the returned value and investment cost.
Taxes, fees, operating expenses and other costs are not added automatically. Include them in your own input assumptions when they matter.

Useful next steps in the same workflow.
Yes. If the amount returned is lower than the amount invested, Toolmera shows a negative ROI and labels the absolute difference as a net loss.
It converts the start-to-finish value change into an equivalent compounded annual rate using the duration you enter.
No. The calculator only uses the values entered. Adjust your inputs if you want those costs reflected.
Simple ROI measures total percentage gain or loss, while CAGR annualizes a start-to-finish value change over time.
