Bankroll & Risk Management — Key Questions Answered
What percentage of my bankroll should I bet?
Commonly 1-3% per bet. Smaller units survive longer losing streaks; larger units risk ruin before your edge plays out.
What is a unit in betting?
A unit is your standard bet size, usually 1-2% of your bankroll. Measuring wins and losses in units keeps staking consistent as your bankroll changes.
What is the Kelly Criterion?
A formula that sizes each bet to your edge and the odds to maximize long-term bankroll growth. It's optimal in theory but sensitive to errors in your probability estimate.
How long can a winning bettor lose?
Longer than most people expect. Even a genuine long-term winner routinely goes on losing runs of 8-10+ bets. Variance hides a real edge over small samples.
What should I track for my bets?
At minimum: date, sport, market, selection, book, odds, stake, result, and the closing line. That's enough to compute ROI, units, and closing line value.
