Understanding Betting ROI
ROI (Return on Investment) measures how much profit you make relative to how much you risk. It's the most important metric for evaluating betting performance.
ROI Benchmarks
- Below 0%: Losing money overall
- 0-2%: Breaking even (typical recreational bettor)
- 2-5%: Good performance (skilled bettor)
- 5-10%: Excellent (professional level)
- Above 10%: Exceptional (rare, may indicate small sample size)
Sample Size Matters
A 20% ROI over 10 bets means little. You need hundreds of bets to know if your ROI is sustainable. Variance can create winning or losing streaks that don't reflect true skill.
