Full Explanation
The Kelly Criterion calculates the optimal percentage of your bankroll to wager. Formula: f = (bp - q) / b, where b = decimal odds - 1, p = probability of winning, q = probability of losing. Most experienced bettors use fractional Kelly (quarter or half) to reduce variance.
💡 Example
Odds 2.00 (b=1), Win prob 55% (p=0.55): Kelly = (1×0.55 - 0.45)/1 = 10% of bankroll.
