Poker stop-loss calculator

What does this result mean?

A poker stop-loss calculator converts a session limit in buy-ins into the cash loss at which you have already decided to leave. It does not claim that stopping after a fixed loss improves the mathematics of the next hand. Its job is behavioural: protect decision quality when fatigue, tilt or the urge to recover losses begins to change how you play. Choose the buy-in size for the game and a limit you will actually honour, then set the rule before the session begins. The result should sit inside your bankroll plan and can be tightened when sleep, focus or game conditions are poor. A stop-loss is not a substitute for leaving earlier when your decisions deteriorate, and reaching it does not prove the game was bad. It simply removes an emotional negotiation at the point where that negotiation is least trustworthy.

How to use the answer responsibly

Treat the calculator as a planning tool, not a verdict on one session. A live poker input is usually an estimate: your win rate is noisy, your standard deviation changes by game type, and your future volume rarely matches the clean number you type into a form. The useful habit is to save the assumptions beside the result so you know what would need to change before the decision changes.

If the result pushes against what you wanted to do, do not smooth the inputs until the answer feels nicer. Make the conservative version first, using a lower win rate, a higher swing rate or fewer weekly hours. Then run the optimistic version. The space between those answers is the real decision area: where a shot needs a stop rule, where a move up needs more buy-ins, or where a good-looking hourly still needs a bigger sample.

Overshove calculators become more useful when the inputs come from your own logged sessions. Rake, tips, travel, hours, stake mix and session length all change the number. A generic benchmark can teach the shape of the problem, but a clean personal log gives the number you should actually act on.
