The 2% rule is deliberately boring: decide your betting bankroll, then stake no more than 2% of it on any single selection. That one constraint protects you from the most common bankroll mistake: letting one match carry too much emotional weight.
Why 2% works
Even strong bettors hit losing runs. A 2% stake means 10 consecutive losses costs about a fifth of the starting bankroll, not the whole account. That still hurts, but it leaves room to keep making calm decisions.
Flat staking beats mood staking
Mood staking is when your stake changes because you feel due a win, annoyed by a loss, or excited by a big price. Flat staking makes the decision before the emotion arrives. The result of the last bet does not get to choose the size of the next one.
How to apply it
- Set a separate bankroll before you bet. Do not include money needed for bills, rent or savings.
- Calculate 2% and make that your maximum normal stake.
- Recalculate only at planned intervals, such as weekly or monthly, not after every result.
- Reduce the stake if betting starts to feel stressful rather than recreational.
When to use less than 2%
Two percent is a ceiling, not a target. Smaller stakes make sense when your edge is uncertain, the market is volatile, or you are testing a new approach. Discipline is not measured by how much you risk. It is measured by whether your staking matches your evidence.
