Casino Bankroll Management — How to Make Your Money Last

The purpose of bankroll management

Bankroll management is not a way to win. The house edge means that over enough rounds, the casino wins. Bankroll management controls how long you play, how much variance you are exposed to, and how much a session costs you. It maximises entertainment for a given budget — not profit.

The 1–5% rule

A widely used guideline is to bet no more than 1–5% of your total session bankroll on a single spin or round. At 1%, a £100 session bankroll means £1 per spin. This gives you at least 100 rounds before you run out of money — more, because not every spin is a total loss.

Separating session bankrolls

Set aside a specific amount for gambling as a completely separate budget from your living expenses. This is the only money you gamble with. Never supplement it with money from other parts of your budget, no matter what happens in a session.

Stop-loss rules

A stop-loss rule says: if I lose X% of my session bankroll, I stop. At 50%, you have enough left to make another decision on another day. Combined with a win target (I stop if I double my starting amount), a stop-loss rule creates structure around a session that emotion alone does not provide.

What does not work

Martingale (doubling after every loss) sounds logical but fails when a losing streak depletes your bankroll before the next win. Systems that increase bets after wins also fail — they are just moving money around inside the same negative-expectation game.
