About this tool
The ROI Calculator measures your return on investment as a percentage of the capital you put in. Enter your initial investment and the final value or net gain, and it spits out a clean ROI percentage instantly. It is useful for anyone evaluating whether a business spend, marketing campaign, rental property, or stock purchase actually paid off in percentage terms that are easy to compare across different decisions.
Reach for this tool when you need a fast, no-nonsense sanity check on a financial decision. It is especially handy when comparing two opportunities of different sizes, since a raw dollar gain can be misleading without knowing what you started with. If you are building a case for a budget request or reviewing past performance, this calculator gives you a defensible number in seconds.
How to use it
- Enter your initial investment amount in the first input field.
- Enter your net gain or your final return value in the second field.
- Select whether your second input is a net gain or a total final value.
- Click Calculate to generate your ROI percentage instantly.
- Review the result and use the reset button to run a new scenario.
- Copy or note the percentage to compare against other investment options.
Pro tips
- Run multiple scenarios back to back by changing only one variable at a time to isolate exactly what drives your ROI.
- ROI ignores time, so a 40 percent return over five years is far weaker than the same return over one year.
