What Bankroll Do You Need for Cash Games?

For no-limit hold’em cash games, keep 20–30 buy-ins of the stake you play, where one buy-in is a full 100 big blinds. That cushion is what lets a winning player ride out the normal swings of cash poker without going broke before the edge pays off. Cash has lower variance than tournaments, so the buy-in count is smaller — but it still has to be big enough that a routine losing stretch can’t bust you.

How many buy-ins for cash games

The right number depends on how you reload and how much swing you can stomach:

• 20 buy-ins — the aggressive floor. Fine if you can top up from outside income and you tolerate downswings calmly.
• 25 buy-ins — the standard for most serious grinders. A sensible balance of growth and safety.
• 30+ buy-ins — conservative. Right when your poker money has to stand entirely on its own, or you play a high-variance, aggressive style.

One buy-in means a full 100 big blinds. If you routinely sit with a short stack, adjust: buying in for 50bb still exposes you to the same variance per hand relative to your stack, so size the cushion off the full buy-in.

Per-stake dollar table

Multiply the buy-in (100bb) by 25 for the standard target:

Stake (blinds)	One buy-in (100bb)	20 BI (min)	25 BI (standard)	30 BI (safe)
$0.05/$0.10	$10	$200	$250	$300
$0.10/$0.25	$25	$500	$625	$750
$0.25/$0.50	$50	$1,000	$1,250	$1,500
$0.50/$1	$100	$2,000	$2,500	$3,000
$1/$2	$200	$4,000	$5,000	$6,000
$2/$5	$500	$10,000	$12,500	$15,000

These are cash bankrolls — money dedicated to poker, never rent or bill money. The full sizing logic across all formats is in how much bankroll you need for poker.

Worked example

You want to grind $0.50/$1 with a standard cushion.

• One buy-in = 100bb = $100.
• Standard target = 25 × $100 = $2,500.
• You’ve saved $2,000. That’s 20 buy-ins — the floor, playable if you can top up but tight otherwise.
• A four-buy-in downswing (routine in cash) drops you to $1,600, or 16 buy-ins. Below the floor, so the rule says move down to $0.25/$0.50 until you rebuild.

The math is deliberately unforgiving on the way down. That’s the point.

The move-up, move-down rules

• Move down fast. The instant your roll falls below the buy-in count for your stake, drop to the level it covers. No exceptions, no “one more session to win it back.”
• Move up slow. Only climb when you clear the count for the next stake and you’ve proven a winning rate over a real sample. The full checklist is in when to move up in stakes.
• Cap table risk. Don’t put more than ~5% of your roll on a single cash table at once.

The asymmetry — quick down, slow up — is what keeps a cash roll alive through the swings.

Live vs online cash

Live games are usually softer, which tempts players to run a thinner roll. Resist it: live hands come slow, rake is proportionally higher at small stakes, and rebuilding after a downswing takes far longer than online. Most live players keep a similar 20–40 buy-in range and simply accept the slower recovery.

Online you see more hands per hour, so variance realizes faster in both directions — a downswing arrives quicker but so does the rebound. Either way, the buy-in ratio is your anchor.

Why 20–30 and not more

Cash games earn their smaller buy-in count from lower variance. A cash winner grinds a steady edge and rarely loses more than a few buy-ins in a single session, because you can top up to a full stack after any hand and your edge applies immediately. Contrast that with tournaments, where you can play flawlessly for fifty events and cash in none — that’s why MTTs demand 100+ buy-ins. Cash sits at the calm end of the variance spectrum, so 20–30 buy-ins genuinely suffices for a proven winner.

Adjusting the count to your game

The 20–30 range isn’t one-size-fits-all. Slide within it based on your reality:

• Higher (30+ BI): you play a loose-aggressive, higher-variance style; your poker money can’t be topped up; downswings rattle your decision-making.
• Lower (20 BI): you play tight, low-variance full-ring poker; you have steady outside income to reload; you’re genuinely comfortable dropping down without ego.

If you play a higher-variance game like short-handed or heads-up, treat 30 buy-ins as the floor — those swings behave more like the tournament end of the scale.

Put it together

Keep 20–30 buy-ins of your cash stake, move down the moment you drop below the count, and move up only when the roll and your win rate both clear the bar.
