How the ROI Calculator Works
Return on investment measures profit relative to cost: subtract what you put in from what you got back, divide by what you put in, and multiply by 100. A $1,000 investment worth $1,500 has a 50% ROI. It’s the universal yardstick for comparing the payoff of investments, projects and marketing spend on equal terms.
For investments held over time, the annualised ROI matters more — it spreads the return across the years so you can compare a quick gain against a slow one. This calculator shows both.
ROI = (final value − invested) ÷ invested × 100
Frequently Asked Questions
How do I calculate ROI?
Subtract the amount invested from the final value, divide by the amount invested, and multiply by 100. $1,000 to $1,500 is a 50% ROI.
What is annualised ROI?
The return expressed per year, which lets you compare investments held for different lengths of time. A 50% return over 2 years is about 22.5% a year.
What is a good ROI?
It depends on the risk and the alternative. Stock markets have averaged roughly 7–10% a year long term; a good ROI beats what you could earn elsewhere for similar risk.
