ROI calculator
Calculator
The calculator needs JavaScript. The tables below give the same numbers for common cases.
How it is worked out
- ROI = (final − invested) ÷ invested × 100 = ($13,500.00 − $10,000.00) ÷ $10,000.00 × 100 = 35%.
- Annualized = (final ÷ invested)^(1 ÷ years) − 1 = 10.5209%.
| Inputs | Answer |
|---|---|
| Amount invested: 10000; Final value: 13500; Years held: 3 | Investing $10,000.00 and ending with $13,500.00 is a return of 35% (10.5209% a year). |
| Amount invested: 5000; Final value: 4200; Years held: 2 | Investing $5,000.00 and ending with $4,200.00 is a return of -16% (-8.3485% a year). |
| Amount invested: 250000; Final value: 410000; Years held: 8 | Investing $250,000.00 and ending with $410,000.00 is a return of 64% (6.3789% a year). |
How to use it
ROI = (final value − amount invested) ÷ amount invested × 100. Turning $10,000 into $13,500 is a 35% return. Dividing a multi-year return by the years is misleading, so the calculator also gives the annualized (compound) return: about 10.5% a year over 3 years.
ROI does not account for risk, taxes or fees unless you include them in the numbers. These are estimates from the numbers you type, not financial advice or an offer; real products add fees and change rates.
