📊 ROI Calculator
Work out the return on any investment — total ROI, net profit, and the annualized return that lets you compare deals of different lengths on equal footing.
What ROI actually tells you
Return on investment measures how much you gained relative to what you put in: net profit divided by the amount invested, as a percentage. It's the simplest way to size up whether something paid off, and it works for anything — stocks, a rental property, a business project, even a course or a piece of equipment.
Why annualized return matters more
Total ROI alone can mislead: a 50% return is excellent in one year and mediocre over twenty. The annualized return converts your total gain into an equivalent yearly rate, so you can compare a two-year deal against a ten-year one fairly. That's the number seasoned investors actually watch.
Using ROI wisely
- Include all costs. Fees, taxes and maintenance reduce real ROI — use net figures for an honest picture.
- Mind the time value of money. A dollar today is worth more than a dollar in ten years; annualized return helps account for that.
- Don't ignore risk. A higher ROI that came with a real chance of large losses isn't automatically better than a steadier one.
- Compare to a benchmark like a broad index fund to judge whether the extra effort or risk was worth it.
Frequently asked questions
How do you calculate ROI?
ROI = (final value − amount invested) ÷ amount invested, expressed as a percentage. Enter both figures above and the calculator returns your net profit and total ROI instantly.
What is annualized return?
It's the yearly rate that, compounded over your holding period, turns your investment into its final value. It lets you compare returns from investments held for different lengths of time on equal terms.
Should I use gross or net figures?
Net. For an accurate ROI, subtract fees, taxes and any ongoing costs from the final value (and add any income received). Gross ROI flatters the result.
Is a higher ROI always better?
Not necessarily. Consider the time it took (use the annualized figure), the risk involved, and the effort. A slightly lower but steadier, lower-risk return can be the better choice.
