❓ Frequently Asked Questions
What is bankroll management?
Bankroll management is the practice of deciding how much to bet on each wager to minimize risk of ruin and maximize long-term growth.
What is the best betting method?
Fixed percentage (e.g., 1-2%) is safest and most recommended for beginners. Kelly criterion maximizes growth if you know your edge, but can be aggressive.
What is risk of ruin?
The probability that you will lose your entire bankroll. Lower bet sizes reduce risk of ruin.
How do I choose my risk percentage?
Start with 1-2% of your bankroll. If you're more risk-averse, use 0.5%. For aggressive play, 3-5% but be prepared for swings.
What is the Kelly criterion?
A formula that calculates optimal bet size based on your edge and odds. It maximizes growth but can be volatile. We use a simplified version.
Should I adjust my bet size after wins/losses?
Yes, with fixed percentage, you recalc after each session. Flat bettors may keep same amount but should review periodically.
Can I use this for sports betting and casino?
Yes, the principles apply to any form of gambling. For casino games with a house edge, your edge is negative – only use fixed percentage.

🧮 Mathematical Formulas
Fixed Percentage: Bet = Bankroll × (Percentage / 100)
Kelly Criterion (simplified for even bets): Bet = Bankroll × (Edge / Odds) — for even odds (2.0), Bet = Bankroll × Edge
Units: Bankroll / Bet Size
Risk of Ruin (approximate): (1 - Edge) / (1 + Edge) ^ Units — decreases as units increase.
