ROI and variance in MTT tournaments: understanding your long-term results
A good MTT player can go through entire months without a notable result, simply because the variance of the format only rewards a small fraction of entrants in each tournament. Understanding your real ROI and sizing your bankroll accordingly is what lets you stay in the game over the long run without panicking over a normal downswing.
3 concepts to tell apart
ROI (Return On Investment)
Your net profit divided by the total of your buy-ins, expressed as a percentage. A 20% ROI means you get back an average of €1.20 for every euro staked, but that number only becomes reliable after a very large number of tournaments played.
ITM (In The Money)
The percentage of tournaments where you finish in the paid places. A high ITM doesn't guarantee a good ROI: you can cash often for small amounts while still being an overall loser over time.
The variance specific to the MTT format
A tournament pays out a handful of big scores to a minority of entrants. Even a player with a real, durable edge can go through dozens of tournaments without a meaningful cash before a profitable run evens out the stats.
Why MTT variance hits harder than cash game variance
In cash game, every hand is independent and the result smooths out relatively quickly over a large number of hands. In a tournament, a single outcome (busting or winning) concludes hours of play — and most of a field's winnings are concentrated on a handful of places. A profitable player can therefore lose more often than they win, while still being +EV over the long run.
Your bankroll needs to be sized accordingly, on the same principle as for cash game but with an even more generous cushion given this highly concentrated distribution of winnings.
This high variance is also why a single isolated re-entrydecision should never be judged on its own: it's your cumulative ROI over hundreds of tournaments that reflects the real profitability of a strategy, not the outcome of a single session.
Frequently asked questions
How many tournaments do you need to evaluate your ROI reliably?
Generally several hundred tournaments, and ideally several thousand for a truly stable sample. Variance in MTTs is such that a sample of a few dozen tournaments tells you almost nothing about your real level.
Does a bad month in tournaments mean I'm playing badly?
Not necessarily. MTT variance can send an otherwise profitable player through months on end without a meaningful result. That's precisely why you should judge your performance on a large sample rather than a single isolated month.
How many buy-ins in bankroll do you need to play MTTs comfortably?
A common benchmark is 100 to 200 buy-ins for the format and stake you play, depending on field sizes and the variance of the format (a Spin & Go or a hyper-turbo requires more of a cushion than a slow-structure tournament).
How can you track your real ROI without calculating it by hand?
A tool that automatically aggregates your tournament history by format lets you track your real ROI and ITM without manually recalculating every result line after every session.
