About this tool
This calculator compares what you get back from an investment with what you paid for it. Return on investment, or ROI, equals the final value minus the cost, divided by the cost, times 100. A positive result means a gain, a negative result means a loss, and the gain itself is simply the final value minus the cost.
Frequently asked questions
What is a good ROI?
There is no single good number, because it depends on the risk and the time involved. A 50% gain over ten years is very different from 50% in one year, so always consider the time period too.
Does ROI include costs like fees?
Only if you include them in the cost you enter. For a fair result, add purchase costs, fees and any other expenses to the cost figure.
