Calculadora ROI - Retorno sobre Investimento em Apostas
Calculadora ROI grátis para apostas esportivas. Calcule seu retorno sobre investimento, lucro líquido e lucro por aposta.
Como usar esta calculadora
- Insira seu valor total apostado (soma de todas as apostas)
- Insira o valor total retornado (pagamentos vencedores incluindo apostas)
- (Opcional) Insira o número de apostas feitas para métricas por aposta
- Veja lucro, ROI % e estatísticas por aposta
Fórmula
Lucro líquido = Total retornado − Total apostado
ROI = Lucro líquido / Total apostado × 100%
Aposta média = Total apostado / Número de apostas
Lucro por aposta = Lucro líquido / Número de apostas
ROIs sustentados acima de 5-10% são típicos de fortes apostadores esportivos em 1000+ apostas; qualquer coisa acima de 20% em uma amostra pequena geralmente é variância, não habilidade.
Perguntas frequentes
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.
