How Much Bankroll Do You Need for Poker?

A safe poker bankroll is 20–30 buy-ins for cash games and 100+ buy-ins for tournaments, kept completely separate from money you need for anything else. The reason isn’t timidity — it’s variance. Even clearly winning players hit long losing stretches, and a too-small bankroll gets wiped out before your edge has a chance to show.

How many buy-ins by format

Different formats swing differently, so they need different cushions.

The looser end of each range (30 buy-ins, 100+ for MTTs) is for players who can’t easily top up their roll, who play higher variance styles, or who simply hate downswings. Tighten toward the lower end only if you’re genuinely comfortable dropping in stakes the instant your bankroll dips.

Why variance demands a cushion

Poker rewards good decisions over the long run — but the short run is noisy. A solid cash-game winner can lose for weeks; a strong tournament player can go dozens of events without a final table. None of that means you’re playing badly. It’s the normal shape of the game.

The bankroll’s job is to keep you in action through those stretches so your edge can play out. Run out of buy-ins mid-downswing and your skill never gets the chance to win the money back. This is also why bankroll management pairs with the math: making +EV decisions like correct pot-odds calls only pays off if you survive long enough to realize the average.

Worked example

You want to play $0.25/$0.50 online cash, where a full buy-in is $50.

• Cash guideline: 20–30 buy-ins → $1,000–$1,500.
• If your poker-only money is $600, you’re under-rolled for $50. Drop to $0.10/$0.25 ($25 buy-in), where $600 is 24 buy-ins — comfortable.
• As that roll grows to ~$1,000, you can move back up to $0.25/$0.50 with a proper cushion.

That single discipline — always playing the stake your bankroll covers — is most of bankroll management in practice.

A simple progression plan

1. Pick your format and its buy-in multiple (say, 25 for cash).
2. Find the highest stake your roll covers at that multiple.
3. Move up only when you’re comfortably above the threshold for the next stake (e.g. 25+ buy-ins of the higher level).
4. Move down immediately when a downswing drops you below the threshold for your current stake. This is the rule beginners skip — and it’s the one that saves bankrolls.

The rules that keep you in the game

• Separate bankroll. Poker money is not rent money. Ever.
• Move down fast, up slow. The asymmetry is deliberate — protect against ruin first, chase higher stakes second.
• Cap table risk. Don’t put more than ~5% of your roll on one cash table.
• Don’t chase losses by jumping stakes to “win it back fast.” That’s the single most common way winning players go broke.

Get the ratios right and you can play through any downswing your edge will eventually overcome. Get them wrong and even a strong player busts. Once your roll is sound, put the focus back on the edge itself: how to play Texas Hold’em, and more in the bankroll management hub.
