How it works
The formula behind this calculator.
ROI = (gain / cost) × 100; Annualized = (final/initial)^(1/years) − 1
- gain
- Profit (or loss, if negative)
- cost
- Initial investment
ROI tells you the percentage return, but doesn't capture time. Annualized ROI normalizes returns to a per-year basis for fair comparison.
Example: Bought at $100, sold at $120 after 2 years: ROI = 20%, Annualized ≈ 9.5%

Tips
- 💡 ROI does not account for time. A 50% return in 1 month is far better than 50% in 5 years. Use annualized ROI for comparison.
- 💡 Include fees and taxes in your cost basis for a true picture.
