How many units should I bet per game?
Comprehensive guide on optimal unit sizing in sports betting and how arbitrage betting eliminates risk and guesswork.
How many units should I bet per game?
The number of units you should bet per game depends on your bankroll size, risk tolerance, and betting strategy, but a common approach is to wager between 1% to 5% of your total bankroll on each bet.
Proper unit sizing helps manage risk and preserve your bankroll during inevitable losing streaks, enabling long-term profitability and stability in sports betting.
Arbitrage betting eliminates much of the guesswork around unit sizing by providing guaranteed profit opportunities regardless of the outcome, making bankroll management simpler and less risky.
The Importance of Unit Sizing
Unit sizing is crucial because it controls how much of your bankroll is exposed on any single bet. Betting too large can lead to rapid losses and potential bankroll depletion, while betting too small may limit growth and profitability. A consistent unit size also helps maintain discipline and avoid emotionally driven decisions.
- •Protects your bankroll from large losses
- •Allows for steady growth over time
- •Encourages disciplined betting habits
💡Example of Unit Sizing Impact
If your bankroll is $1,000 and you bet 5 units at $10 each, losing several bets in a row can quickly diminish your funds. Betting 1 unit per game reduces this risk and extends your betting longevity.
Bankroll = $1,000; Unit size = 1% = $10; Betting 5 units = $50 per bet
Factors Influencing How Many Units to Bet
Several factors affect how many units you should wager per game. These include your bankroll size, confidence in the bet, volatility of the sport, and your personal risk tolerance. Adjusting unit size based on these factors can improve overall results but requires experience and careful judgment.
- •Bankroll size determines maximum unit size
- •Higher confidence bets may warrant larger units
- •Sports with higher variance may require smaller units
- •Risk tolerance varies among bettors
Confidence-Based Betting
Some bettors increase unit size for bets they feel more confident about. While this can increase profits, it also increases risk. Arbitrage betting avoids this uncertainty by guaranteeing profit regardless of confidence level.
- →Larger bets on high-confidence picks
- →Smaller bets on uncertain outcomes
- →Arbitrage betting removes the need for confidence-based adjustments
💡Adjusting Units by Confidence
If you normally bet 1 unit but feel very confident in a particular game, you might increase to 2 units. However, this increases exposure to risk if the bet loses.
Normal unit = $10; Increased unit = $20 for high confidence
Flat Betting vs Variable Betting
Flat betting involves wagering the same number of units on every game regardless of perceived value or confidence. Variable betting adjusts units based on factors like odds or confidence. Flat betting is simpler and reduces emotional decisions, while variable betting can increase profits but with more risk. Arbitrage betting simplifies the process by focusing on guaranteed profit margins rather than guesswork.
- •Flat betting ensures consistent bankroll management
- •Variable betting requires experience and discipline
- •Arbitrage betting removes variability and guesswork
Advantages of Flat Betting
Flat betting is less complex and helps avoid overexposure on risky bets. It is a favored strategy for beginners and those prioritizing bankroll preservation.
- →Easy to implement
- →Reduces emotional betting
- →Improves long-term sustainability
💡Flat vs Variable Betting Example
A bettor using flat betting wagers 2 units on every game. Another bettor varies between 1 and 5 units based on confidence, increasing risk and potential for large swings.
Flat: 2 units x $10 = $20 per bet; Variable: range from $10 to $50 per bet
Using the Kelly Criterion for Unit Sizing
The Kelly Criterion is a mathematical formula that calculates the optimal bet size based on the perceived edge and odds. While it can maximize growth, it requires accurate estimation of probabilities and can lead to aggressive bet sizes. Arbitrage betting removes the need for probability estimates, ensuring profit without complex calculations.
- •Kelly formula: (bp - q) / b, where b = odds-1, p = probability of win, q = probability of loss
- •Maximizes bankroll growth over time
- •Risk of overbetting if estimates are off
Limitations of Kelly Criterion
Estimating true probabilities is difficult and errors can cause losses. Fractional Kelly (e.g., half Kelly) is often used to reduce risk. Tools like ArbitUp help manage complex betting calculations but arbitrage betting avoids these uncertainties entirely.
- →Requires precise probability estimates
- →Can lead to large bet sizes
- →Fractional Kelly reduces risk
💡Kelly Criterion Example
If the odds are 2.0 (evens) and your estimated probability of winning is 60%, Kelly suggests betting 20% of your bankroll. This aggressive bet size can be risky without accurate data.
b=1, p=0.6, q=0.4; Kelly fraction = (1*0.6 - 0.4)/1 = 0.2 or 20%
Managing Risk Through Unit Sizing
Proper unit sizing is the foundation of risk management in sports betting. By limiting each bet to a small percentage of your bankroll, you reduce the chance of ruin during losing streaks. This strategy ensures you can stay in the game longer and recover from losses more effectively. Arbitrage betting complements this approach by providing risk-free profit opportunities that do not rely on bankroll fluctuations.
- •Limits exposure on any single bet
- •Preserves bankroll during losing streaks
- •Supports consistent, sustainable betting
💡Risk Management Example
A bettor with a $5,000 bankroll betting 2% units risks $100 per game. Even if they lose 5 games in a row, the max loss is $500, protecting the bankroll from catastrophic depletion.
Bankroll = $5,000; Unit size = 2% = $100; 5 losses x $100 = $500 loss
