What Is Bankroll Management?
Your bankroll is the amount of money you set aside purely for gambling. Management means having a written plan for how big each bet will be (your unit), how much you are willing to risk in a session/day, and when to stop. It replaces guesswork with a routine you can follow even when emotions run high.
Why It Matters: Variance, Tilt & Risk
All games have variance streaks of wins and losses that don’t always match short-term expectations. Without rules, people react to downswings by chasing losses or raising stakes to “get even,” which is how bankrolls disappear. A simple system prevents tilt, smooths swings, and keeps you in the game long enough to enjoy the good runs.
Set Up Your Bankroll (Step-by-Step)
- Choose a safe amount: Use money you can afford to lose. Never borrow or use bill money.
- Separate it: Keep it in its own e-wallet, card, or cash envelope so you can see the balance clearly.
- Pick a period: Monthly or weekly. Fund it on a schedule, not mid-session.
- Write rules: Unit size, session stop-loss, daily cap, time limits, and a review routine.
- Commit: Success is sticking to the rules, not forcing a result in one session.
Unit Sizing: 1% vs 2% with Examples
Your unit is the default stake for a spin/hand/bet. For most players, flat staking is best: use the same unit every play and only change it when your bankroll changes significantly.
- 1% units (conservative): Best for high variance games or new players. A €1,000 bankroll means €10 per play.
- 2% units (aggressive): Faster swings; only if you’re comfortable with bigger drawdowns. A €1,000 bankroll means €20 per play.
- Recalculate: Adjust unit size when your bankroll moves ~25% up/down or at month-end.
Example: With a €500 bankroll, 1% units = €5. If you lose 5 units in a session (−€25), stop and review. If your bankroll grows to €750, 1% becomes €7.50 round to €7 or €8 and keep it steady until the next review.
By Game: Slots, Tables, and Sports
Slots: Variance is high. Prefer 1% units and longer timeboxes. Don’t raise stakes to “unlock” a bonus it’s a trap.
Table games: Use constant units; avoid progression systems that multiply stakes after losses. They turn bad runs into disasters.
Sports betting: Flat stakes per play. Parlays increase variance; use them sparingly. If you can truly estimate edge, you can use a small fraction of Kelly; otherwise stay with flat staking.
Stop-Loss, Win-Stop, Timeboxing
- Session stop-loss: 3–5 units. Hit it? End the session no “one more” bets.
- Daily exposure cap: About 8 units in total stakes for the day.
- Optional win-stop: Bank profits at +4–6 units and take a break.
- Timeboxing: Pre-set play windows to reduce fatigue and tilt (e.g., 45–90 minutes).
Tracking & Post-Session Review
After each session, jot down date, game/market, stake, odds/house edge, result, and a quick note about decisions (good or bad). Review weekly: did you chase losses, break rules, or play tired? Improvement comes from honest notes, not from one lucky session.
Drawdowns & Rebuild Plan
Downswings happen. If your bankroll drops ~25%, reduce your unit size to match the new bankroll and take a short cool-off. Rebuild gradually with smaller stakes. If you go bust, step away and refill only on your scheduled funding date. Never reload in anger.
Common Mistakes & Myths
- “I’ll just raise stakes and win it back.” That’s tilt talking write a stop-loss so you don’t listen.
- Progression systems beat variance. They magnify it. A bad streak becomes unaffordable fast.
- Parlays create value. They create variance; only use small, occasional parlays if you accept that risk.
- Changing unit size mid-session. Pick a unit and keep it until your next review.

FAQ: Bankroll Management for Gambling
What is a “unit” and why does it matter?
A unit is your default stake per spin/hand/bet (e.g., 1% of your bankroll). Using fixed units keeps your risk steady and prevents random stake jumps that lead to tilt.
Should I use 1% or 2% units?
1% is conservative and better for high-variance games or new players. 2% is more aggressive and swings more. Pick one and stick to it for the whole session.
When do I recalculate my unit size?
After a ~25% bankroll change or on a fixed schedule (e.g., monthly). Don’t change unit size mid-session—wait until your next review.
What is a session stop-loss?
A hard limit (commonly 3–5 units) where you end the session if reached. It protects you from chasing losses when emotions spike.
How many units should I risk in a day?
Many players cap daily exposure around 8 units. You can also set a win-stop at +4–6 units to protect profits and reset.
Do progression systems (Martingale, etc.) help?
No. They multiply stakes during losing streaks and can wipe out your bankroll. Flat staking with stop-loss rules is safer and more sustainable.
Is Kelly Criterion good for sports betting?
Only if you can reliably estimate your edge. If you use it, keep stakes tiny (25–50% of Kelly). If you can’t estimate edge, stick to flat 1–2% units.
How should I handle parlays?
Parlays increase variance. If you use them, keep stakes small and separate from your main flat-stake plays.
I hit a big win—do I increase my unit?
Not mid-session. Bank profits, finish the session, then consider a recalculation at your next scheduled review.
What if I’m on a downswing?
Reduce unit size to match the new bankroll, take a cool-off, and review notes to spot rule-breaking or tilt. Don’t chase losses.
What’s the difference between bankroll and session budget?
Your bankroll is the total set aside for gambling. A session budget is the portion you use in one sitting—bounded by stop-loss and time limits.
