Bankroll Management
The discipline of keeping enough dedicated funds and playing stakes small enough to survive normal downswings without going broke.
Definition
Bankroll management is the practice of setting aside a dedicated poker fund and choosing stakes conservative enough that ordinary variance cannot wipe it out. Because poker outcomes swing widely in the short run, even a skilled player can lose over many sessions, so guidelines suggest holding many buy-ins for your stake, more for higher-variance formats like tournaments and Spin & Gos than for cash games. Sound bankroll management also means never playing with money you cannot afford to lose, moving down in stakes during downswings, and treating the bankroll as separate from living expenses. It is a risk-control tool, not a winning strategy: it cannot turn a losing player into a winner, only prevent a winner from busting due to variance and stop losses from spiraling.
Worked example
A cash-game player with a 5,000 bankroll follows a rule of at least 20 buy-ins, so they play a 25/50-cent game (100 buy-in) rather than risking a large fraction of their roll at higher stakes.
Why it matters
For learners, bankroll management is the single biggest protection against going broke and against betting money they cannot afford to lose. For professionals, it is the foundation that lets a real edge express itself over the long run instead of being erased by a normal downswing.
