Staking Formulas
The mathematics behind each staking strategy
Kelly Criterion
Where b = decimal odds - 1, p = win probability, q = 1 - p
Percentage Staking
$1000 bankroll at 3%: $1000 × 0.03 = $30 stake
Fibonacci
Step 5 with $10 base: $10 × 5 = $50
Martingale
After 3 losses with $10 base: $10 × 2³ = $80
Understanding Staking Strategies
Flat Staking
The simplest approach: bet the same amount every time. Low variance but doesn't capitalize on edges.
Percentage Staking
Bet a fixed % of current bankroll. Stakes grow with wins and shrink with losses automatically.
Kelly Criterion
Optimal mathematical formula for maximizing growth. Bet size proportional to your edge over the bookmaker.
Fibonacci System
Progressive system using Fibonacci numbers. Gentler than Martingale but still risky.

Pro Tips
Start Conservative
Begin with 1-2% stakes until you prove your edge over 500+ bets. It's easier to increase stakes than recover from ruin.
Use Half Kelly
Full Kelly is mathematically optimal but volatile. Half Kelly gives 75% of growth with much less variance and drawdown.
Avoid Progressive Systems
Martingale and similar doubling systems have near-100% ruin probability long-term. Stick to flat or proportional staking.
