For most online multi-table tournament (MTT) players, 200 buy-ins is a sensible working bankroll. 100 buy-ins is the commonly quoted minimum, and it only suits low-variance formats or players who can refill from outside income. Large-field, top-heavy formats such as PKOs and Mystery Bounties call for 300 or more.
Published advice agrees on the range. Common recommendations run from 100 buy-ins as a floor to 200 to 300 for standard online MTTs, and some cautious players hold far more. There is no single correct number. The right count depends on the format, your field size, how much of your edge is real, and how much a downswing would hurt.
A "buy-in" here means your average buy-in, including the rake. If you play a mix from $5 to $22, use your average across the month, not your favorite stake.
Tournament payouts are top-heavy. In a large field, roughly the top 15% of players cash, and most of the profit sits in the top few finishing spots. Even a winning player can go dozens of tournaments without a cash. That is normal variance, not a sign that your strategy is broken.
Your ROI decides how long the swings last. A player with a small edge needs a much bigger bankroll than a player with a large one, because the edge takes longer to show up. For a deeper look at the mechanics, see our guide to poker tournament variance reduction. For the full framework on moving up and down, see our poker tournament bankroll management strategy.
These are rules of thumb, not guarantees. They reflect the range that published bankroll guides commonly use, adjusted for how much variance each format carries.
| Format | Minimum buy-ins | Comfortable buy-ins | Why |
|---|---|---|---|
| Sit and Go (9-max, single table) | 100 | 150 | Small fields, about 3 paid places, fast feedback |
| Small-field MTT (under 200 entries) | 100 | 150 to 200 | Lower variance than large fields |
| Standard MTT (200 to 2,000 entries) | 150 | 200 to 300 | Top-heavy payouts, long droughts |
| Large-field MTT (2,000+ entries) | 200 | 300+ | The biggest share of profit sits in a few rare deep runs |
| Satellites (flat-paying seats) | 50 to 100 | 100 to 150 | Flat prizes reduce variance, but you win a ticket, not cash |
| PKO / Mystery Bounty | 200 | 300 to 400 | Bounty luck adds variance on top of the payout structure |
| Turbo / hyper (fast structures) | 200 | 300+ | Less skill edge per tournament, so a longer sample is needed |
If you are unsure which row applies, use the more conservative one. The cost of holding a slightly larger bankroll is slower progress. The cost of holding too small a bankroll is going broke while you were still profitable on paper.
Say you play an average buy-in of $10 in standard MTTs with fields of about 1,000.
If you play PKOs at the same average buy-in, move to the 300 to 400 row. That means $3,000 to $4,000. The buy-in did not change. The variance did.
If your bankroll is $2,200 and you want to play $22 tournaments, that is 100 buy-ins, which is below the minimum for a standard MTT. The math says stay at $10, or take a limited number of $22 shots with money you can afford to lose.
Most players do better with a clear rule than with a feeling. A simple version:
Rules like these protect you from the most common leak in tournament bankrolls, which is playing higher than the roll supports after a big score.
Your buy-in target is not fixed. If your real edge is larger, you can hold fewer buy-ins. If it is smaller than you think, you need more. Most players overestimate their ROI, because tournament results are noisy and a few big scores make a sample look better than it is.
Two practical ways to improve your edge are better tournament selection and better registration timing.
Late registration. GTO Wizard's ICM analysis of late registration found that a late entrant's seat is worth about 10.9% more than the buy-in in a standard MTT. In a flat-paying satellite, the figure is about 29.76%. These are ICM seat equity gains, not ROI. The PKO is the exception. A late starting stack in a PKO loses about 14% of its value, so late registration hurts there. Sources: the ICM benefits of late registration and the hidden cost of late reg in PKOs. For timing detail by format, see our data-backed guide to the best time to late register.
Overlay. An overlay happens when a tournament's guaranteed prize pool is larger than the buy-ins collected. Every entrant then plays for more than they pay in. Entering overlay tournaments raises your expected value per entry, which is an edge that does not depend on how well you play. Our guide to finding poker tournament overlays step by step covers how to spot them.
The lobbies change every minute, and nobody can watch a dozen of them while playing. Profitmaxxer scans 12 poker networks every 30 seconds and sends Telegram alerts for overlays and for Max Late Reg timing. As of this writing its public stats page shows about $54.9 million in total overlay detected across roughly 82,900 observations over 198 days. That averages out to about $660 per overlay observation, and about $277,000 per day across the networks. Those totals count what was detected in the lobbies. They are not what any single player earns, because you can only enter a limited number of tournaments.
Here is how this connects to bankroll size:
Pick your row, count your average buy-in, and set your move-up and move-down lines before your next session. Then let the volume play out.
