Poker Bankroll Rules: Cash Games vs Tournaments

You sit down, same skills as last month, same focus, same grind. Yet your roll is smaller. It was not one bad beat. It was a slow leak. A long downswing. Or a few bold shots with no plan. This is the fork in the road. One path keeps you playing your A-game when luck is cold. The other path ends with “cashier: $0”. This guide is about that first path. Simple rules. Real math. Plans you can follow.

Quick take (but not the whole story)

Cash games: plan for 3,000–5,000 BB for online 6-max if your edge is steady; live cash can be 2,000–3,000 BB.
Tournaments (online): for regular-speed MTTs, hold 150–300 ABI; for turbo/hyper or PKO, use 250–600 ABI.
“ABI” = your average buy-in across all games you play.
Lower edge or tougher pools need more. Softer pools or lower rake need less.
Step up with a buffer. Step down fast when a shot fails.

That is the quick map. But your real need depends on two things: how wild your results swing, and how strong your edge is. Let’s unpack that in plain words.

What’s actually at risk: cash vs MTT goals are not the same

Cash games pay you every hand. Your win is “bb/100” (big blinds per 100 hands). Your swings come from the size of pots, your style, the rake, and the strength of the table. You can quit any time and sit again later at the same stake. So your bankroll rule can scale with your bb/100 and your standard deviation per 100 hands (std/100).

Tournaments are different. You pay one buy-in and play until you bust or win it all. Most money goes to the top spots. Your results are lumpy. You can run dead for months and still play great. Your key stats are ABI, ROI (return on investment), field size, speed (regular, turbo, hyper), and format (classic or PKO). Bankroll rules for MTTs must be wider to survive long dry spells.

So the right rule is not one magic number. It is a range. The range shifts with your edge, your game type, and your risk taste. A safe roll gives you time for your edge to show up.

A small math pit stop (no PhD needed)

Three simple ideas help you choose your range:

Standard deviation (variance): how big the swings are. In cash, people quote std/100 in big blinds. In MTTs, think of “swing per tournament” in buy-ins. Bigger variance → bigger roll.
Edge: your real win rate. In cash, bb/100. In MTTs, ROI%. Bigger edge → smaller roll (within reason).
Risk of ruin and Kelly: “Kelly” is a way to size bets when you know edge and variance. In poker, we use it as a guide, then cut it down to be safe. If you want a primer, see Kelly criterion basics. For a broader view, see risk of ruin in gambling.

We will not do heavy math here. The key is this: as swings get bigger or your edge gets smaller, your bankroll needs rise. And this is not a flaw. It is the cost of playing a high variance game like poker.

Reality check: the downswings you will actually face

In cash, even solid winners can lose 20–30 buy-ins on a bad run. Loose-aggressive styles can swing more. In tough pools with high rake, add even more spread. If your std/100 is 90–110 bb/100 online, a stretch of 100k hands can still look flat or red, even with +3 bb/100 true win rate.

In MTTs, the story is starker. A good regular with 20% ROI at small stakes can brick 500–1000 events. That is not rare. It depends on field size, speed, and your multi-tabling. Use a tournament variance simulator to see full curves for your ABI and ROI. Also read this clear post on how much variance in MTTs. When you see those charts, bankroll rules make instant sense.

The table you came for: bankroll bands that won’t lie to you

Read this as bands, not one rigid number. Your pool, rake, and table count will shift you up or down a bit. If you want a short explainer on std/100 in cash, this guide is neat: standard deviation in BB/100 explained.

Cash 6-max online	std/100 ≈ 70–110 bb/100	Breakeven / low	5,000–8,000 BB	Only after clear win rate at current stake	-5 to -8 buy-ins on shot	High rake and tough regs push you higher
Cash 6-max online	std/100 ≈ 70–110 bb/100	Moderate (+2 to +4 bb/100)	3,000–5,000 BB	When you hold 40–50 buy-ins for next stake	-5 to -8 buy-ins on shot	Table select to reduce std
Cash 6-max online	std/100 ≈ 70–110 bb/100	High (5+ bb/100)	2,000–3,000 BB	At 50+ buy-ins for next stake	-4 to -6 buy-ins on shot	Still respect drop rules
Cash live full ring	std/100 ≈ 50–90 bb/100	Breakeven / low	3,000–5,000 BB	After steady profit over months	-5 to -8 buy-ins on shot	Live edges are often bigger
Cash live full ring	std/100 ≈ 50–90 bb/100	Moderate	2,000–3,000 BB	40–50 buy-ins for next stake	-5 to -8 buy-ins	Game select matters more than charts
MTT online — Regular	SD per event ≈ 60–100 buy-ins	Breakeven / low ROI	300–500 ABI	Step when you hold 250–300 ABI for target games	Drop if roll < 150–200 ABI	Large fields need the higher end
MTT online — Regular	SD per event ≈ 60–100 buy-ins	Moderate ROI (10–30%)	150–300 ABI	At 200–250 ABI buffer	Drop if roll < 120–150 ABI	Keep ABI stable across a session
MTT online — Regular	SD per event ≈ 60–100 buy-ins	High ROI (30%+)	100–200 ABI	At 200+ ABI buffer	Drop if roll < 100–120 ABI	Still expect long dry spells
MTT online — Turbo/Hyper	SD per event ≈ 100–200+ buy-ins	Moderate ROI	250–400 ABI	At 300+ ABI	Drop if roll < 150–200 ABI	Faster blinds = more swing
MTT online — PKO	SD per event ≈ 120–220+ buy-ins	Moderate ROI	300–500 ABI	At 350+ ABI	Drop if roll < 180–220 ABI	Bounty swings raise variance
MTT live — Regular	Lower volume, lumpy results	Moderate ROI	50–100 ABI	At 100+ ABI	Drop if roll < 60–80 ABI	Volume is the real limit

Notes on ABI: if you play a $22, a $33, and two $11s in a block, your ABI is ($22 + $33 + $11 + $11)/4 = $19.25. Keep your mix steady so your ABI stays within plan.

Cash games: rules that scale with your edge

Cash lets you exit bad tables and sit at good ones. Use this power. Your bankroll rule is not just “X buy-ins”. It is “X buy-ins at your true edge and your pool’s std/100”. If you mass table, std grows and you need more. If you table select and play deep only with weak spots, std drops and you need less.

Good long-form tips live here: cash game bankroll guidelines. Below is a clear plan you can run:

Pick a base stake where you are a winner over at least 100k hands.
Hold 30–50 buy-ins at that stake. 40+ is safer online. Live can be 20–30 if your edge is clear and you can reload from income.
Build a “shot ladder”: when your roll reaches 50 buy-ins for the next stake, take a 5 buy-in shot. If you lose 5 buy-ins there, drop back. Repeat.
Set daily stop-loss rules that match your std/100. Often that is 3–5 buy-ins in fast online pools, 2–3 live.
Track your win rate by position and spot. If you cannot keep +2 to +4 bb/100 at current games, do not move up yet.

Do not ignore rake. Rake can crush small-stake win rates. If your site takes too much, your safe bankroll must be higher. Or you must find softer tables to keep the same roll target.

Tournaments: ABI logic, field size, and format multipliers

Think in ABI first. Then apply multipliers for speed, field size, and format. Then set shot rules by bankroll bands, not by a single event.

Regular-speed online MTTs: 150–300 ABI is a solid band for 10–30% ROI. Your “shot” is to allow a few bigger events once your roll is 200–250 ABI, but keep your session ABI within plan.
Turbo/Hyper: use 250–400 ABI or more. Blinds rise fast; variance is high even for top players.
PKO: bounty money changes risk. Early KOs add swing. Use 300–500 ABI unless your edge is very high. Read about progressive knockout dynamics to see why.
Live MTTs: volume is low; swings last longer in time. The field is softer, so 50–100 ABI often works if you have outside income. If poker is your main income, go to the high end of that range.

To judge field size and payout, browse real data. ABI and field-size impact is easy to see on Hendon Mob pages. For structure sheets and payout ladders, check a payout structures example from WSOP. Wider, top-heavy payouts mean wider bankroll bands.

One more note: do not let one big Sunday spike your ABI by surprise. Pre-plan your “Sunday boost” roll. If you want to fire a $109 while your usual is $22, save a small “shot box” separate from your main roll.

Two build paths: choose the one that fits your life

Path A — You have outside income (evening grinder)

You can be a bit bold. In cash, 25–35 buy-ins at your main stake can be okay if you drop fast when the shot fails.
In MTTs, 120–200 ABI for regular speed is workable if you keep each session’s ABI tight and do not chase.
Use a small “shot budget” each month (2–5% of roll) for higher games. When used, stop. Refill only next month.

Path B — Poker is your main or key side income

Be conservative. In cash, keep 40–60 buy-ins (4,000–6,000 BB) for online. Live can be 30–40 if games are soft and you have low life costs.
In MTTs, 250–500 ABI is not crazy. It buys time to realize your ROI and shields your mental game.
Set a fixed monthly “payroll” you can withdraw. Keep the rest in the roll. If you must draw more, lower your ABI or stake by one band.

Field notes from grinders (mini case studies)

Case 1 — NL25 online, steady but swingy

Maria plays NL25 6-max. Her tracker shows +3 bb/100 over 200k hands. Her std/100 is 95 bb/100. She plays four tables. She feels most swings on days she adds two more tables. For her, 4,000 BB is sane (40 buy-ins). She plans a shot at NL50 at 50 buy-ins for NL50 (5,000 BB). If the shot drops 6 buy-ins, she snaps back. She also works on rake: lower table count, more table select, cut marginal spots. That can trim std/100 by 10–15 and lets her keep the same roll with less stress.

Case 2 — Online MTT reg, ABI $27, ROI ~20%

Chris plays a daily mix of $11–$33 with an ABI of $27. His ROI is near 20% over 5k games. He plays 8–10 tables, 3–4 days a week. He sets bankroll at 300 ABI = $8,100. On Sundays he allows up to 10% of his roll to be in play. He fires an extra $55 only when his roll is above $9,000. If his roll dips under $6,000 (≈220 ABI), he trims the schedule to $11–$22 until back above $7,500.

Case 3 — The rake trap in small-stake cash

Omar beats live $1/$2 but is break-even online at NL10. The pool is tight and the rake is high. His plan is not just “more buy-ins”. He studies rake spots (limp pots, small pots OOP) and avoids them. He reads about cash game rake effects. He table-selects and uses fewer tables. Now his std/100 drops and his true win rate creeps up. With a real edge, his 3,000–4,000 BB bankroll feels safe again.

Your toolkit: tracking, calc, and where to play

Good records are your guard rails. Use a tracker. Two common tools are PokerTracker 4 and Holdem Manager. For range work, Equilab is simple and free. For MTT planning, plug your ABI and ROI into a variance tool like the Primedope one linked above. For money tracking, a plain sheet is fine; start with a simple template in Google Sheets.

Where you play also shapes your bankroll need. Rake, rakeback, trust, game traffic — all matter. If you need a clean, up-to-date place to compare rooms, see Pro-Casinos.com reviews. It lists key facts like rake, rakeback policy, game types, and license. Note: some sites may use affiliate links; always judge by clear criteria first.

Shot-taking rules you can follow this week

Define a “shot box”: 5 buy-ins for cash; 5–10% of roll for MTTs. When it is gone, stop the shot.
Pre-set a drop rule: -5 to -8 buy-ins in a cash shot; for MTTs, if roll falls below your lower ABI band, cut session ABI at once.
Only raise your main game when you clear a 30-day check: winning at current stake, stable mindset, stable schedule.
Never let a single big buy-in push session ABI above plan by more than 10–15%.

Mindset and logistics (small things that save big money)

Keep a split: poker roll is not rent money. If you must use it for bills, lower your stakes and grow again.
Play well-rested. Tired play raises std, which demands a bigger roll.
Warm up with 10 hands of review. Cool down with 5 marked hands. Steady process reduces silly dips.
Use auto top-up in cash to keep SPR plans clean and reduce tilt from uneven stacks.

Responsible play: the line you never cross

Bankroll rules help, but they are not a shield from harm. If poker feels out of control, pause. Talk to someone. In the US, see the National Council on Problem Gambling. In the UK/EU, visit BeGambleAware or GamCare. Set deposit limits, time limits, and cool-off periods. Seek local advice on tax and legal rules if poker is income for you. This guide is education, not financial advice.

Mini-FAQ

Is 100 ABI enough for MTTs if I only late-reg or aim for finals?

No. Late-reg can raise variance and cut ROI. Finals are rare. Use at least 150–300 ABI for regular speed. More for turbo, hyper, or PKO.

How do I adjust for high rake in micro cash?

Play fewer tables, table-select, and fold more small pots out of position. You will need more buy-ins while you fix leaks. Move sites if rake is too high and rakeback is poor.

What about satellites?

Sat variance can be lower if the bubble pays many seats, but it spikes if the field is reg-heavy. Track ROI and keep 100–200 ABI as a base, more if you mass-table turbos.

Can I mix formats in one roll?

Yes, but set bands by the higher-variance format. If you grind cash and add MTTs on Sunday, size your roll for the MTT part of your schedule too.

How fast can I move up in cash?

Climb one stake at a time. Take small shots with a set stop. Only lock in the jump after you show a win rate over a real hand sample at the new level.

Your next steps (a short checklist)

Pick your main format and write down your target band (BB for cash, ABI for MTTs).
Set shot-up and drop-down rules on one card near your screen.
Log every session. Track ABI per session for MTTs; BB won and std feel for cash.
Run a variance sim for your MTT ROI and ABI. Accept the curve before you play.
Audit rake and table quality. If they are bad, change site or change game.
