Your ROI

ROI = (Net profit / Total wagered) × 100। ₹1 लाख wagered, ₹5,000 profit: 5% ROI। Recreational: -5% to -15%। Semi-pro: +2% to +5%। Any positive ROI = better than 95% of bettors।

Track

Every bet: date, match, type, odds, stake, result। After 200+ bets: patterns emerge।

⚡ 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.
