Sports Betting Bankroll Calculator
Calculate optimal unit size, monthly budget, and risk of ruin based on your bankroll, win rate, and betting volume.
Units Rule
Never more than 1-5% per bet। 1 unit = 1-2% of bankroll। ₹10,000 bankroll: 1 unit = ₹100-200। Standard bet: 1 unit। High confidence: 2-3। Never more than 5। A 10-bet losing streak (statistically inevitable) loses only 10-20%।
Ruin Risk
1% bets at 55% rate: ruin risk ~0%। 10% bets: ~40%। Bankroll management = difference between surviving 10 years and going broke in 3 months।
The single most common mistake recreational bettors make: chasing losses by doubling bet size. This is a martingale strategy and it has a 100% probability of catastrophic failure given enough time. After a loss, bet the same amount or less — never more. Your edge comes from selection, not from sizing.
