💰 Bankroll & Variance Guide
The Bankroll Guide
How much you actually need to play your favorite game without going broke. Real numbers, sourced math, no wishful thinking — and clear advice for hobbyists, serious players, and pros.
The five rules
If you only read this section, you'll have 90% of what matters.
1
Bankroll = money you've designated for poker only. Not your rent, not your savings, not money you'd notice losing. Only money pre-allocated for this game.
2
Cash games: 20 buy-ins minimum, 30-50 for serious play. Pros run 50-100+. Online needs more than live.
3
Tournaments: 100-200 buy-ins. Tournaments have brutal variance — you can go 30-50 events without a meaningful cash even as a winning player.
4
Move down without ego. When your bankroll drops below 15-20 buy-ins for cash (or 50-100 for MTTs), drop a stake. The math doesn't care about your pride.
5
Track sessions honestly. Date, location, hours, win or loss. Even a notes app works. Most people overweight wins and forget losses — tracking fixes that.
👤Which player are you?
Every bankroll recommendation depends on what you're trying to do. The same player needs a $4,000 bankroll for $1/$2 if poker is fun and a $20,000 bankroll if it's their job. Pick the tier that honestly fits — not the one your ego prefers.
🎮
Hobbyist
Plays for fun. Has another income.
Cash games: 20 buy-ins. Tournaments: 50-100 buy-ins. If you bust your bankroll, it's annoying — not catastrophic. You can replenish from your paycheck.
📈
Serious
Wants to build a roll, climb stakes.
Cash games: 30-50 buy-ins. Tournaments: 100-200 buy-ins. Bigger cushion lets you withstand normal downswings without changing your game or moving down constantly.
💼
Professional
Poker is income. No outside paycheck.
Cash games: 50-100+ buy-ins. Tournaments: 200-500 buy-ins. You also need a separate emergency fund for living expenses. Going broke means you can't play, which means you can't earn.
Honest assessment matters more than aspiration: Most "I'm going pro next year" players are actually serious-tier hobbyists who've conflated wanting it with being it. There's no shame in that — but if you size your bankroll like a pro when you're playing like a serious hobbyist, you'll come up short on both fronts.
🃏Cash game bankroll table
Standard 100bb max buy-ins for No-Limit Hold'em. The numbers below assume you're a winning player at the stake — bankroll alone won't save a losing player from going broke; it just slows it down.
| Stake (Live) |
Max Buy-in |
Hobbyist (20×) |
Serious (30-50×) |
Pro (50-100×) |
| $1/$2 | $200 | $4,000 | $6,000–$10,000 | $10,000–$20,000 |
| $1/$3 | $300 | $6,000 | $9,000–$15,000 | $15,000–$30,000 |
| $2/$5 | $500 | $10,000 | $15,000–$25,000 | $25,000–$50,000 |
| $5/$10 | $1,500 | $30,000 | $45,000–$75,000 | $75,000–$150,000 |
| $10/$25 | $3,000 | $60,000 | $90,000–$150,000 | $150,000–$300,000 |
| $25/$50 | $5,000 | $100,000 | $150,000–$250,000 | $250,000–$500,000 |
Live cash gets a discount: Live cash games are slower (about 30 hands/hour vs 60-100+ online) and typically softer, so live players can use the lower end of these ranges. Online cash players should target the higher end — and if you're multi-tabling, target above the high end.
🏆Tournament bankroll table
Tournaments are higher variance than cash games because of their top-heavy payouts — the difference between min-cashing and final-tabling is enormous, and even great players can go long stretches without a deep run. The numbers below reflect that.
| Buy-in |
Hobbyist (50×) |
Serious (100-200×) |
Pro (200-500×) |
| $25 | $1,250 | $2,500–$5,000 | $5,000–$12,500 |
| $60 | $3,000 | $6,000–$12,000 | $12,000–$30,000 |
| $100 | $5,000 | $10,000–$20,000 | $20,000–$50,000 |
| $200 | $10,000 | $20,000–$40,000 | $40,000–$100,000 |
| $500 | $25,000 | $50,000–$100,000 | $100,000–$250,000 |
| $1,000 | $50,000 | $100,000–$200,000 | $200,000–$500,000 |
| $5,000+ | Most pros at this level use staking, swaps, or selling action — not pure bankroll |
Why tournaments need so many buy-ins: Even in a tournament you finish in the top 15%, you're typically losing money or breaking even — the real ROI comes from final-table runs and outright wins, which by definition are rare. A 30-tournament cashless streak is well within normal variance for a winning MTT player.
Sit & gos and small fields: 9-handed and turbo SNGs need fewer buy-ins (50-100) because variance is more contained. But 1,000+ player MTTs and super-turbos need the high end — sometimes 300-500 buy-ins for serious play, given how rarely you'll go deep.
📊Why these numbers are right
If you've never played seriously, these bankroll requirements probably look wildly oversized. They're not. The math of poker variance is genuinely brutal — and most casual players massively underestimate how big "normal" downswings can be.
Here's what the actual variance looks like, sourced from the standard analyses used by pros:
- A solid online 6-max NL player (3 BB/100 win rate, 90 BB/100 standard deviation) needs around 67 buy-ins to keep their risk of ruin under 5% over a meaningful sample. That's 6,700 big blinds. At $1/$2, that's $13,400.
- Increase that player's variance to 110 BB/100 (typical for aggressive styles or Pot-Limit Omaha) and the bankroll requirement jumps to over 100 buy-ins.
- Drop the win rate to 1.5 BB/100 (more realistic for marginal winners or tougher games) and you're looking at 200+ buy-ins to stay safe.
A good rule of thumb: whatever bankroll you think you need, double it. Then triple-check with a variance calculator before you trust it.
The takeaway isn't that you need an absurd bankroll to enjoy poker — recreational players don't need to optimize for "less than 5% risk of ruin over 100,000 hands." It's that the swings are real, and treating poker like it's a smooth-trending profit curve is exactly how casual players get blindsided by their first 20-buy-in downswing.
📐The Kelly criterion
The Kelly criterion is a 1956 formula by John Kelly Jr. (Bell Labs) that calculates the mathematically optimal fraction of your bankroll to bet given your edge and the odds. It's used everywhere from Wall Street position sizing to professional sports betting to — yes — poker.
The formula in its simplest form:
f* = (bp − q) / b
Where f* is the optimal fraction of your bankroll, b is the odds received (decimal odds minus 1), p is your probability of winning, and q = 1 − p is your probability of losing.
How Kelly applies to poker
Pure Kelly is hard to apply to poker hands directly because every hand has continuous decisions and uncertain probabilities. But Kelly is extremely useful for two specific things:
- Tournament buy-in sizing: Given your ROI and ITM% from a meaningful sample, Kelly tells you the maximum buy-in you should play given your bankroll.
- Shot-taking discipline: Kelly is a sanity check on whether a stake-up shot is bankroll-justified or just an ego move.
Fractional Kelly — what most pros actually use
Full Kelly is mathematically optimal for long-term growth, but it's also maximally aggressive — and assumes you know your true edge perfectly. Nobody knows their true edge perfectly. So most professionals use "Half Kelly" or "Quarter Kelly":
- Full Kelly: Mathematically optimal growth, but very volatile. A 1/3 chance of halving your bankroll before doubling it.
- Half Kelly: ~75% of the growth rate of full Kelly with dramatically lower volatility. The most common professional choice.
- Quarter Kelly: Even more conservative. ~50% of full Kelly's growth, but smooth enough to be psychologically sustainable.
Kelly's biggest weakness: The formula requires accurate probability estimates. Most poker players overestimate their edge — sometimes by a lot. If you input a 5 BB/100 win rate when your true rate is 1 BB/100, Kelly will tell you to be way more aggressive than is actually safe. When in doubt, halve your edge estimate, then halve your Kelly. The pros call this "calibrated humility."
🪜When to move up (and down)
Moving up — checklist before you take a shot
Don't move up just because your bankroll allows it. The best stake-up moments combine three signals:
- You have the bankroll for the higher stake at your tier (hobbyist, serious, pro). Not "almost." Have it.
- You've shown a sustained win rate at your current stake. 50,000+ hands online or 100+ hours live as a positive winner. A two-week heater isn't proof.
- You feel calm at current stakes. If pots at your current level still make your hands sweat, the higher stake will paralyze you. Master the emotional layer first.
Taking shots — the smart way
Even when ready, full move-ups are risky. The smarter approach is "shots" — small samples at the higher stake before committing fully:
- Set a clear bankroll cap for the shot (e.g., 5 buy-ins at the higher stake). When that's gone, you go back down.
- Don't extend the shot mid-session because you "feel close." Stick to the cap. Discipline is the entire point.
- Take notes — was the table actually beatable, or was it tougher than expected? Did your decisions hold up under the higher pressure?
- If the shot succeeds, take more shots. After a few successful shots, you've earned the move.
Moving down — without ego, without drama
Moving down is the move that separates long-term players from broke players. It's not failure; it's discipline. Common rules:
- Cash games: Drop a stake when bankroll falls below 15-20 buy-ins for current level.
- Tournaments: Drop down when below 50-100 buy-ins for current level.
- Always have a pre-decided trigger. "If I drop to $X, I move down." Don't make the decision in the heat of a downswing — make it now.
The pro mindset: Pros don't agonize about moving down. They do it the moment the math says so, then climb back up when the bankroll permits. Hobbyists treat moving down as humiliating. That difference in attitude is one of the biggest reasons most hobbyists eventually go broke and most pros don't.
📓Track everything
You can't manage what you don't measure. Tracking sessions is the single most underrated bankroll discipline — most casual players don't do it, and as a result they have wildly distorted views of their own results.
What to track at minimum:
- Date and location. Patterns matter — some venues are systematically softer or tougher.
- Hours played. The denominator that matters more than chips. Win rate is hourly for cash, ROI per buy-in for tournaments.
- Win or loss in dollars. Net of any tips, food, parking — what actually changed your bankroll.
- One sentence of notes. "Quiet table, soft," "ran terrible," "left tilting after 4-2." Future you will thank present you.
Tools range from free to pro:
- Free: A notes app, a spreadsheet, or a Google Sheet template. PokerBankrollTracker (web) is also free and surprisingly capable.
- Mobile apps: Poker Income, PokerStack, Poker Bankroll Tracker. Most are free or very cheap. Best for live grinders who want quick session entry.
- Pro tools: PokerTracker 4 and Hold'em Manager 3 are the standards for online. Auto-track every hand, generate variance reports, identify leaks. Cost: roughly $90-$150 one-time.
🚫Common mistakes
Almost every bankroll disaster comes from one of a small number of failure modes. Knowing them in advance lets you catch yourself before they happen:
- Mixing bankroll with life money. The single biggest one. Once "rent money" and "poker money" sit in the same account, you've lost the natural firewall that protects both.
- Playing scared after a big loss. Down 3 buy-ins in a session, you start checking-down strong hands and folding marginal spots — bleeding EV exactly when you can least afford it.
- Chasing stakes after a heater. One great session at the next level isn't a green light; it's variance. Wait for the sample size.
- Refusing to move down. Ego-driven. Costs people their bankrolls every day. The biggest tell of an amateur is "but I'm a $5/$10 player" said by someone with a $5/$10 bankroll's worth of leftover scraps.
- Not tracking. "I'm probably about even this year" almost always means "I'm down significantly but won't acknowledge it." Track and find out.
- Borrowing money to play. If you're at a casino and tempted to use the ATM cash advance, the session is already over. Walk away.
- Treating freerolls and bonus dollars as bankroll. They're nice, but they're not your bankroll until they're cashed out and in your account.

Frequently asked questions
The questions players ask most often about bankroll management.
How many buy-ins do I need for cash games?
For recreational play: 20 buy-ins is the standard minimum. For serious live cash players: 30-50 buy-ins. For professionals (poker as primary income): 50-100+ buy-ins.
So at $1/$2 NL Hold'em with a $200 max buy-in, a hobbyist needs $4,000, a serious player needs $6,000-$10,000, and a pro should target $10,000-$20,000+. Online cash games typically need more buy-ins than live (often 30-50+ for serious play) because variance is higher with faster, multi-tabled play.
How many buy-ins do I need for tournaments?
Tournaments have much higher variance than cash games because of their top-heavy payouts. Sit & gos: 50-100 buy-ins. Multi-table tournaments (MTTs): 100-200 buy-ins for serious play, 200+ for professionals.
So if you want to regularly play $50 MTTs, target $5,000-$10,000 in your dedicated tournament bankroll. The reason: in MTTs you can go 30-50 tournaments without a meaningful cash, even as a winning player.
What is the Kelly criterion in poker?
The Kelly criterion is a mathematical formula that determines the optimal percentage of your bankroll to risk on a bet given your edge. For poker, it's most useful as a buy-in sizing guide: never risk more than your edge × your win probability of your bankroll on a single tournament or session.
In practice, most players use "fractional Kelly" (half or quarter Kelly) because full Kelly is too volatile and assumes perfect knowledge of your edge — which nobody actually has.
When should I move up in stakes?
The standard rule: move up when you have the recommended bankroll for the next stake, AND when you've shown a sustained win rate at your current stake (typically 50,000+ hands online or 100+ hours live as a winning player).
The combination matters — having the bankroll without the win rate just means you have more money to lose at a tougher stake. Take "shots" (small samples at the higher stake) before fully moving up, and have a clear plan for when to move back down if it doesn't go well.
When should I move down in stakes?
Move down when your bankroll drops below 15-20 buy-ins for your current stake (cash games) or 50-100 buy-ins (tournaments). Moving down is not a sign of failure — it's the disciplined response to variance.
Many players resist it because of ego, but the math doesn't care about your ego. The pros move down without hesitation when their bankroll says to. Build the habit early.
What is the difference between live and online bankroll requirements?
Live games typically need a smaller bankroll than online for two reasons: (1) live games are softer, so your win rate is usually higher, and (2) live games are slower (30 hands/hour vs 60-100+ online), so variance is naturally lower per hour.
A common rule: live cash players can get away with 20-30 buy-ins; online cash players should target 30-50+ for the same stakes. Online tournament players especially need bigger bankrolls because they often play multiple tables simultaneously, multiplying variance.
Should I have a separate bankroll for poker?
Yes. Always. A poker bankroll should be money you've specifically allocated for poker — separate from rent, savings, emergency funds, or any money you can't afford to lose. Mixing them is the single most common path to gambling problems.
Even casual players should have a designated "poker money" envelope, account, or app — not because it's required, but because it makes it impossible to accidentally play with money you needed for something else.
How much variance should I expect in poker?
More than you think. A solid online NL Hold'em 6-max player (3 BB/100 win rate, 90 BB/100 standard deviation) needs around 67 buy-ins to keep risk of ruin below 5% over a meaningful sample. Even great players experience 30-40 buy-in downswings as a normal part of the game.
A 100,000-hand sample is considered "short-term" for measuring true win rate. The takeaway: variance is much, much wider than most players intuitively expect. Bankrolls aren't conservative — they're realistic.
