The Flat Betting Model
The flat betting approach is the most straightforward and safest method for managing your bankroll . This strategy involves wagering the same amount on every bet, regardless of your confidence level or recent performance .
With flat betting, you'll need to decide between two approaches:
- Risk Method: Bet a fixed amount (e.g., 1 unit) on every wager
- To Win Method: Adjust your bet size to win a consistent amount, accounting for different odds
This method provides excellent bankroll protection and ensures steady growth if you maintain a winning percentage above the break-even point .
The Percentage Model
Similar to flat betting, the percentage model adjusts your unit size based on your current bankroll rather than using a fixed amount . If you start with $1,000 and use a 2.5% unit size, your first bet would be $25. After winning and growing your bankroll to $1,025, your next bet would be $25.63.
This approach capitalizes on winning streaks by automatically increasing bet sizes as your bankroll grows, but it can also make recovery from losing streaks more challenging .
The Confidence Model
For bettors who can accurately assess their edge on different wagers, the confidence model allows for variable bet sizes based on perceived value . Standard bets remain at 1 unit, but high-confidence plays can justify 2-3 unit wagers .
Before implementing this strategy, track your confidence levels on paper bets to verify that your most confident selections actually perform better than your standard plays .
The Kelly Criterion
The Kelly Criterion is a mathematical approach that calculates optimal bet sizes based on your estimated win probability and the odds offered . The formula is:
Bet Size = (bp - q) / b
Where:
- b = odds received (decimal odds - 1)
- p = probability of winning
- q = probability of losing (1 - p)
While mathematically sound, the Kelly Criterion can recommend aggressive bet sizes that many bettors find uncomfortable . Many professionals use a fractional Kelly approach, betting only 25-50% of the recommended amount .
