Bankroll Management for Tournament Poker Players

Bankroll management is the discipline of keeping enough money reserved for poker that variance cannot wipe you out. Even a winning player goes broke if they play stakes too large for their bankroll. This is not about being cautious: it is about staying in the game long enough for your edge to play out.

What Is a Poker Bankroll?

Your bankroll is the money set aside exclusively for poker. It is separate from your day-to-day finances. The reason this separation matters is that poker has high variance, meaning you can lose many buy-ins in a row even when you are making correct decisions. If your poker money is mixed in with rent and groceries, a standard downswing can create real financial stress and pressure you into making bad decisions at the table.

How Many Buy-ins Do You Need?

The number of buy-ins you need depends on the format you play. Tournaments have far more variance than cash games because most of your profit comes from rare deep runs, so they require a larger cushion.

These figures are not arbitrary. They come from the mathematical relationship between your edge, the variance of the format, and the probability of going broke before your results level out. A 10% ROI over a large sample is meaningless if you run out of money in the first 30 tournaments.

What Is Risk of Ruin?

Risk of ruin is the probability that your bankroll hits zero before you recover. With 20 buy-ins and a moderate edge, you might have a 30% chance of going broke. With 100 buy-ins, that same edge might carry a 2% risk of ruin.

A $10 average buy-in in 500+ player fields with a 10% ROI and a bankroll of $100 will result in you going bust 80% of the time.

Two factors drive this number:

Your ROI. A higher edge shrinks the risk of ruin because each tournament is working harder for you on average. A player running 5% ROI needs a larger bankroll than a player running 20% ROI at the same stakes.

Variance. Larger fields with top-heavy prize structures (most money going to the top 3 spots) create wilder swings. Even if your ROI is identical, a 1,000-player tournament requires more buy-ins than a 50-player tournament because your profit is concentrated in rare outcomes.

Moving Up and Down Stakes

A simple rule: move up when your bankroll supports the higher stakes, move down when a downswing reduces it below the minimum for your current stakes.

Say your minimum for $20 MTTs is 50 buy-ins ($1,000). You run well and reach $2,000, which is 50 buy-ins for $40 tournaments. You can consider moving up. If you then run badly and drop back to $1,200, which is only 30 buy-ins at $40, move back down to $20 until you rebuild.

This feels frustrating when you are in a downswing, but it protects you from the scenario where a bad run at stakes you cannot afford ends your poker entirely.

Shot-Taking

A shot take is when you play a higher stake than your bankroll strictly supports, usually with a capped loss. For example: your normal game is $10 MTTs but a good $30 tournament is running. You play it with the intention of stopping at $30 rather than continuing to shot-take if it goes badly.

Shots are acceptable as long as you define your exit point before you play. The mistake is not taking occasional shots: it is continuing to reload into higher stakes after losing, which bypasses the purpose of bankroll management.

Common Mistakes

Playing stakes you cannot afford. This is the most common mistake. Losing three buy-ins at a level that represents a large percentage of your bankroll creates pressure that leads to tilted play, which leads to faster losses.

Not separating poker money from living expenses. When poker money and bill money are in the same account, you will eventually face a decision where you feel you need to win. That feeling changes how you play.

Moving up too soon. A few good scores at your current stake do not guarantee you are ready for the next level. The player pool is tougher, variance is the same, and your edge may shrink. Build a bankroll that covers the higher stake comfortably before moving up.

Not moving down. Pride makes players stay at stakes they can no longer afford after a downswing. Moving down is a tactical decision, not an admission of failure.

Treating a downswing as evidence you are losing. A 30-tournament losing streak is well within normal variance for a winning MTT player. Evaluate your game by the quality of your decisions, not the short-term results.

A Practical Starting Point

If you are new to tournament poker, start at the lowest available stakes and build 50 buy-ins before moving up. This might feel slow, but it gives you the experience to know whether you have an edge before committing larger amounts. Use the Variance Simulator to see what a realistic run of 500 tournaments looks like at your expected ROI.

The goal of bankroll management is not to make poker risk-free. It is to ensure that normal variance cannot end your poker before you have had a fair chance to prove your edge.
