What Is Bankroll Management?
Bankroll management is the practice of properly sizing your bets relative to your total betting funds. It's the difference between going broke during a losing streak and surviving to bet another day.
📐 The Unit System
1 Unit = 1-3% of your total bankroll
If you have a $1,000 bankroll with 2% units, 1 unit = $20. Bet 1-3 units per play depending on confidence.
Why Units Matter
Using units instead of dollar amounts keeps your bets proportional as your bankroll grows or shrinks. It prevents emotional betting and ensures you never risk too much on a single play.
Recommended Unit Sizes
| Bettor Type | Unit Size | Bankroll | Risk Level |
|---|---|---|---|
| Recreational | 3-5% | $200-500 | Higher variance |
| Casual | 2-3% | $500-2,000 | Moderate |
| Serious | 1-2% | $2,000-10,000 | Lower variance |
| Professional | 0.5-1% | $10,000+ | Lowest variance |
⚠️ The #1 Rule
Never bet more than you can afford to lose. Your betting bankroll should be completely separate from money you need for bills, savings, or emergencies.
