What Is Betting ROI?
Sample Size Matters

Seu ROI

ROI = (Lucro líquido ÷ Total apostado) × 100. Se apostou R$10.000 e lucrou R$500: ROI = 5%. Profissionais visam 3-7%. ROI positivo coloca você acima de 95% dos apostadores.

Referências

Apostador recreativo: -5% a -15%. Informado: -2% a +2%. Semi-pro: +2% a +5%. Pro: +3% a +7%.

⚡ CalcWolf Insight

The most successful bettors are not the best at picking winners — they are the best at finding value. A 55% win rate at -110 odds (7.3% ROI) is far more profitable than a 60% win rate at -200 odds (0% ROI). The relationship between win rate and odds determines profitability, not win rate alone.
