Bankroll management is the least glamorous skill in poker and the one that quietly decides whether you survive long enough to be good. You can play well and still go broke if your roll is too thin for the swings, and you can play a modest game profitably for years if it is not. This guide gives you the numbers, the reasoning behind them, and a way to stop guessing at where your money actually comes from.
What bankroll management actually protects you from
Poker results are noisy. Even a clear winner goes through stretches that look exactly like losing, because the short-term outcome is dominated by variance rather than skill. Bankroll management is the buffer that lets your edge play out without a bad run ending your poker before the maths catches up.
The core principle is simple and worth stating plainly: the number of buy-ins you need scales with variance, not with how good you feel. Confidence is not a bankroll. A high-variance format needs a deeper roll than a low-variance one, whatever your win rate, because the swings are larger and last longer.
The numbers, by format
These are working guidelines, not laws. Adjust up if you are risk-averse or poker is your income, down only if you can easily reload from outside poker.
If you play more than one format, hold a roll for the highest-variance one you play regularly. A cash player who occasionally fires a big tournament should not fund those shots from the cash roll without accounting for them.
Live needs a little more than online
Two things push the live requirement up. First, you play far fewer hands per hour, so variance takes longer to smooth out over the same number of sessions. Second, live poker has costs online does not: travel, accommodation for a festival, food, the occasional missed day of work. A live tournament roll that ignores expenses is not a real roll. The short version is that live players should sit at the upper end of every range above, and budget a festival trip as a whole rather than just the buy-ins.
Moving up, and moving down
Most players think about moving up in stakes and never plan to move down, which is exactly backwards. Set a clear rule for both before you need it.
A workable version: take a shot at the next stake when your roll clears the buy-in requirement for it, and drop back down the moment it falls below the requirement for your current stake. The drop-down rule is the one that saves careers, because it removes the ego decision from a losing run and makes it mechanical. You are not admitting anything by moving down. You are protecting the roll that lets you move back up.
Why you cannot manage what you do not measure
Here is the part most players skip. You cannot run a bankroll you only know approximately. If your results live in your head and a phone note, two things happen: you remember the wins more clearly than the losses, and you have no idea which games actually pay you.
A proper bankroll tracker fixes both. Log every session, cash and tournament, in seconds. Then read the breakdowns, because that is where the money hides. Your win rate by stake tells you where you are actually beating the game. Your profit by venue often reveals a goldmine and a leak you did not know about, one room you crush and another that quietly costs you. Your variance view stops a rough fortnight from lying to you about your ability.
The tracker also handles the things a spreadsheet gets wrong: staking cuts, multi-currency trips with daily conversion, rebuys and expenses logged as they happen rather than reconstructed from memory. Over a season, that is the difference between knowing your real hourly and estimating it.
Discipline is a habit, not a mood
Bankroll management fails at the moment it matters most, when you are running bad and the game looks good and dropping down feels like giving up. The way through is to make the rules mechanical before the emotion arrives, and to keep a record honest enough that you cannot argue with it. Study your leaks with a combo counting drill and price your calls with a pot odds drill, but protect the roll that lets you keep playing at all. If you play staked, the stable and backer tools track makeup and markup so a deal never turns into an argument.
