Bankroll management is the foundation of professional poker. Even skilled players go broke without proper bankroll sizing due to variance.
The Formula: Required bankroll depends on your win rate, variance (standard deviation), and acceptable risk of ruin. Higher variance games need more buyins.
Key Rule: Never risk money you cannot afford to lose. Your poker bankroll should be completely separate from your life expenses.
For cash games, 20-50 buyins is standard ($2000-$5000 for $1/$2). Tournaments require 100-200 buyins due to higher variance. Your exact requirement depends on your win rate and acceptable risk of ruin.
Risk of ruin (RoR) is the probability of losing your entire bankroll before it grows. A 5% RoR means you have a 5% chance of going broke. Lower risk tolerance requires larger bankrolls.
Yes, many pros recommend this. Cash games and tournaments have very different variance profiles. A ${symbol}10,000 total bankroll might be split into ${symbol}6,000 for cash (30 buyins at ${symbol}1/${symbol}2) and ${symbol}4,000 for tournaments (40 buyins at ${symbol}100 MTTs).
Higher win rates require smaller bankrolls. A 10 BB/100 winner at ${symbol}1/${symbol}2 might only need 15 buyins for 2% RoR, while a 2 BB/100 winner needs 50+ buyins. Breakeven or losing players need infinite bankrolls.
Common rule: Move up when you have 30+ buyins for the next level, move down when you drop below 20 buyins for your current level. Some pros use 'shots' - taking 3-5 buyin shots at higher stakes while maintaining their regular bankroll.
