베팅당 이익 = 순이익 / 베팅 수
5-10% 이상의 지속 가능한 ROI는 1000+ 베팅에 걸친 강력한 스포츠 베터에 일반적입니다; 작은 샘플에서 20% 이상은 일반적으로 기술이 아닌 분산입니다.
자주 묻는 질문
What is a good ROI in sports betting?
Professional sports bettors typically aim for a long-term ROI of 5-10%. Anything above 3% over a large sample (5000+ bets) is considered exceptional. Sharps often run thinner (2-3%) on bigger volumes; recreational winning bettors run at 5-15% with smaller volumes but more variance.
How is ROI different from yield?
Yield is another name for ROI in betting context. Both measure profit as a percentage of total wagered. The terms are interchangeable — yield is more common in horse racing and European betting, ROI more common in US sports betting and matched betting.
Why does sample size matter?
Short-term ROI is dominated by variance, not skill. A 20% ROI over 50 bets means almost nothing — random variance can produce that easily. To distinguish skill from luck you generally need 1000+ bets with consistent staking and odds before ROI starts to reflect your true edge.
Should I track ROI by sport, market, or bet type?
Yes — track each segment separately. Total ROI may hide that you’re profitable on NHL totals but bleeding money on NBA spreads. Granular tracking is the foundation of any improvement loop in long-term betting.
