59. Bankroll Management

Risk Management

Bankroll management is the systematic approach to allocating and wagering gambling funds to maximize the probability of long-term success while minimizing the risk of ruin. For advantage players, bankroll management involves sizing bets relative to their mathematical edge and total available capital to ensure they can withstand normal statistical variance without depleting their funds. Professional gamblers typically use a “unit” system, where one unit represents a small percentage of their total bankroll (often 0.5% to 2%), and bet sizes are scaled in units based on the perceived edge. For casino operations, bankroll management refers to maintaining sufficient cash reserves (float) on the gaming floor to cover large payouts and normal winning fluctuations without operational disruption.

In practice

Conservative bankroll management suggests having at least 100 maximum bets for table game play. For card counters, a common rule is 100-200 betting units. Casino float requirements are calculated based on the standard deviation of game outcomes and the maximum payout exposure of the games offered.
