KEY TAKEAWAYS
A bankroll is money set aside only for poker, and a buy-in guideline says how many buy-ins of a given game that money should cover. Many cash game players use a cushion somewhere around 20 to 40 buy-ins, and some use considerably more. Those numbers are conventions, not rules or promises: no number of buy-ins makes losing impossible. They exist to make a losing streak survivable instead of ruinous.
This guide explains how to count buy-ins, why the recommended number varies, a worked example that shows when to move down, and the mistakes that damage a bankroll fastest. The examples assume no-limit hold’em cash games where one buy-in is 100 big blinds (bb). Poker involves real financial risk, and nothing here suggests that poker is reliable income.
What a Buy-In Guideline Actually Measures
A buy-in guideline is a ratio: your bankroll divided by the buy-in of the game you play. If your bankroll is $1,500 and you play games with a $50 buy-in, you hold 30 buy-ins. The ratio matters more than the dollar amount because it describes how far a downswing can go before the money runs out.
The reason for counting in buy-ins is variance. Even a winning player goes through long stretches of losing, because the cards, opponents and hand outcomes swing results far more than most people expect over hundreds or thousands of hands. A cushion of buy-ins is what lets you keep playing through those stretches without being forced out.
A guideline is also a risk-management tool, not a measure of skill. A bigger cushion lowers the chance of going broke, but it never removes it. Treat every figure in this article as a convention that people adjust to their own situation.
Why the Right Number of Buy-Ins Varies
No single figure fits everyone because the factors behind it differ. Four things move the number the most: your actual win rate, the style of game, how comfortable you are with swings, and how easily you could rebuild the bankroll if it disappeared.
Win rate is the hardest to judge. Players often overrate their edge, and a small sample can fool anyone. If you are unsure how strong your edge is, a larger cushion is the safer assumption, since a smaller edge means longer losing stretches. Game style matters too: loose, aggressive games with many big pots usually swing more than quiet, tight ones.
Your own situation counts as much as the game. If a bankroll loss would affect your rent, bills or savings, you should not be playing with that money at all. A player who can easily replace the money from a regular income can accept more risk than one who cannot. When in doubt, a more conservative cushion is the safer choice.
The table below shows how people commonly think about it. These are illustrative conventions, and sources and players disagree on exact figures, so use them to frame your own plan, not as targets to hit.
| Situation | Typical direction | Reason |
|---|---|---|
| Unsure of your win rate | More buy-ins | A smaller real edge means longer losing runs |
| Loose, high-variance games | More buy-ins | Bigger pots create larger swings |
| Money you cannot easily replace | More buy-ins, or smaller games | Going broke costs more |
| Tournaments instead of cash games | Many more buy-ins | Results depend on a few large payouts |
Read the table as directions, not exact amounts. Tournaments need a larger cushion in buy-ins than cash games because most entries return nothing and a few finishes make up most of the results, so long losing streaks are normal.
Example: Counting Buy-Ins and Moving Down
Suppose a player has a $1,500 poker bankroll and follows a personal guideline of 30 buy-ins for no-limit cash games. The largest buy-in this bankroll supports is $1,500 ÷ 30 = $50, which is a game where 100bb equals $50.
Now suppose a bad run brings the bankroll to $1,200. At a $50 buy-in, the cushion has dropped to $1,200 ÷ $50 = 24 buy-ins, below the 30-buy-in guideline. Under the same guideline, the supported buy-in becomes $1,200 ÷ 30 = $40, so the player moves down to a $40 game until the bankroll rebuilds.
The reverse also works as a limit, not a trigger. If the bankroll grows to $2,100 the guideline supports a $70 buy-in ($2,100 ÷ 30), but the player may prefer to wait for a larger cushion first, since a move up should be backed by a sample of results and comfort in the game, not only by the number. Note that these figures are illustrative and the 30-buy-in guideline is an example, not a recommendation for everyone.
Moving down in this example is not a failure. It is what a guideline is for. A plan that tells you to step down protects the money that lets you keep playing.
How to Build and Use a Bankroll Plan
Start by deciding what the bankroll is: a fixed amount of money kept apart from living expenses, with its own account or record if possible. Money you need for rent, food, debts or bills is not part of it, and borrowing money to play should never be part of any plan.
Then write down your rules before you play, since decisions made mid-session are shaped by emotion. A simple plan covers three items: the number of buy-ins you want for each stake, the point at which you move down, and the point at which you will stop playing for the day. It helps to track results so you can see your real record rather than your memory of it.
Game choice and table choice also protect the bankroll. Choosing softer games lowers the chance of long losing runs, which connects to how to pick a profitable cash game. If you also play tournaments, remember that their different structure changes the picture, as discussed in tournament strategy by stack size. Keep a separate cushion for each format you play.
Common Bankroll Mistakes
Playing stakes the bankroll cannot support is the most common error. A single bad session at too high a stake can consume a large share of the bankroll, and the pressure that follows pushes players toward poor decisions.
Moving up to win losses back is the most dangerous. After a downswing the urge to jump to a bigger game promises a quick recovery, but it raises variance at the exact moment the cushion is thin. Chasing losses is how small setbacks become large ones.
Mixing poker money with living money removes the protection a bankroll gives. When the same account pays rent and buys in, every loss becomes a personal financial problem and every decision gets harder.
Another error is ignoring tilt. Frustration after losing hands makes players play too loosely and too aggressively, which costs more than the original loss. Finally, judging your skill by a short sample misleads in both directions: a hot streak can seem like proof of a big edge, and a cold one can seem like proof of no edge.
Bankroll Management Online, Live and in Tournaments
Online players see many more hands per hour than live players, so swings arrive faster online, and a bankroll can move a long way in a single week. Live players see fewer hands per hour, but the same buy-in logic applies.
Tournament players face the largest swings. Most entries lose the buy-in, and the big payouts come rarely, so long runs without a cash are normal even for strong players. Many tournament players therefore hold a much larger cushion than cash players, and some prefer smaller buy-ins to keep the number of entries high.
Playing responsibly means more than managing numbers. Set limits on time and money, stop if you are upset or tired, and take a break if poker stops being enjoyable. Legal age and the legality of real-money poker vary by state and venue, so confirm the rules where you play. If gambling is causing problems, talking to a professional support service can help.
What to Study After Bankroll Basics
The next topics are how variance behaves over a large number of hands, how to track results honestly, and when and how to take a shot at a higher stake. Learning to separate a good decision from a good result is the skill that connects bankroll management to strategy, because it keeps a bad run from changing a sound approach.
