Bankroll management: how to size your stakes

Bankroll management is the habit of deciding in advance how much money you set aside for betting and how much of it goes on any single bet. It does not make bets win. It limits damage during the losing runs that every bettor meets, and it keeps betting a bounded form of entertainment rather than a financial risk.
What a bankroll is
Your bankroll is a fixed sum of money you can afford to lose entirely, kept separate from rent, bills, savings and debt repayments. It should be money whose loss would not change your life. If losing it would, it is not a bankroll, and the right number is lower or zero.
Keep it physically separate where possible, for example in a dedicated account, so you can always see how much is left. Do not top it up automatically after a losing run. A rule that only works until you break it is not a rule.
Why staking matters
Even a bettor with a genuine edge faces variance. Suppose you win 55% of your bets at even money. Over a long run that is profitable, yet losing streaks of seven or eight in a row are not unusual across a few hundred bets. If each bet is a large share of your bankroll, one such streak can end the whole project before the edge has time to show.
Flat staking
Flat staking means the same amount on every bet, usually between 1% and 2% of the starting bankroll. With a bankroll of 500 and a 1% unit, every bet is 5.
- Simple, and easy to track.
- Protects against the temptation to chase losses with bigger stakes.
- Ignores how confident you are in a given bet, which is the main trade-off.
For most beginners flat staking is the sensible default.
Percentage staking
With percentage staking you bet a fixed percentage of the current bankroll, so stakes shrink after losses and grow after wins. At 2% of 500 you bet 10. After a bad run leaves 400, the same rule gives 8. The stake can never take you to exactly zero, which is a real advantage. Its drawback is that you recalculate constantly, and a small bankroll produces awkward stakes.
A word on Kelly
The Kelly criterion is a formula for the stake that maximises long-run growth when you know the true probability exactly. It is stake fraction = (probability x odds - 1) / (odds - 1). With a 40% estimate at odds of 3.00, that is (0.4 x 3 - 1) / 2 = 10% of the bankroll.
Two cautions apply. Kelly assumes your probability is correct, and real estimates are noisy, so full Kelly staking is aggressive and swings wildly. Many people use a fraction of it, such as a quarter, if they use it at all. Our expected value calculator shows the Kelly figure next to the edge so you can see how sensitive it is to your estimate.
Practical rules that work
- Decide the bankroll and the unit size before you place the first bet.
- Set a maximum stake per bet and a maximum amount you will lose in a day or a week. Stop when you hit it.
- Never chase losses by raising stakes to win the money back. This is the most common route to serious losses.
- Keep a record of every bet: date, market, odds, stake and result. Without records, memory flatters you.
- Review after a fixed number of bets, such as 100, not after a single weekend.
- Withdraw profits on a schedule rather than letting them fund bigger stakes by default.
Warning signs
Pause and take a break if you are betting money meant for other purposes, hiding your betting from people close to you, feeling anxious when you cannot bet, or increasing stakes to feel the same excitement. These are signs that betting has stopped being a pastime, and speaking to a support service is a good next step.
Key takeaways
Choose a bankroll you can afford to lose, use small and consistent stakes, set hard limits and keep records. Good bankroll management reduces the chance of ruin but cannot create an edge and does not guarantee profit.
Betting is for adults only (18+). Treat it as paid entertainment, never as income, and get help if it becomes a problem.
