ROI (Return on Investment) Calculator
Return on investment (ROI) tells you, in percent, how much an investment made or lost against what went in. It puts two completely different opportunities on one scale.
Enter what you invested and what it's worth now. Add the holding period if you want the annualized return too.

$10,000.00 grew to $15,000.00, a 1.5× return
Invested vs. value now
You invested $10,000.00 and it's now worth $15,000.00, a gain of $5,000.00 (50% return). That's about 14.47% a year gained.

Before you rely on this
Results are generic estimates using standard time-value-of-money formulas, the same math everywhere. Real-world figures depend on your country's tax rules, rounding, fees, and lender or product terms, which vary by jurisdiction. Treat this as a guide and confirm important numbers with a local professional.
How the roi calculation works
ROI is (final value − initial value) ÷ initial value, as a percentage. It ignores time, which is why two investments with the same ROI can be very different.
Annualized ROI fixes that: (final ÷ initial)^(1/years) − 1. A 50% gain in one year is a far better result than the same 50% spread over ten.
Tips
- Comparing investments held for different periods? Always use the annualized return.
- Put every cost into the initial value: fees, and taxes where relevant. That's your real ROI.
- A high ROI on a tiny amount can matter less than a modest ROI on a large one.
Frequently asked questions
How do you calculate ROI?
Subtract the initial value from the final value, divide by the initial value, multiply by 100. This calculator does it instantly, and adds the annualized figure if you provide a time period.
What is a good ROI?
Depends on risk and time. As a benchmark, broad stock indexes have historically averaged roughly 7-10% a year before inflation. Compare any opportunity's annualized ROI against that.
Why is annualized ROI more useful?
Because it accounts for how long your money was at work. A 50% total return in one year is a completely different story from 50% over a decade. Only the annualized number shows it.
