Risk Management for Sports Bettors: Protecting Your Bankroll

You can have the most accurate prediction model in the world and still go broke. How? Poor bankroll management. The difference between professional bettors and recreational ones isn't just their win rate — it's how they size their bets and manage risk.

The Foundation: Fixed Bankroll

The first rule is simple but critical: define a bankroll that you can afford to lose entirely, and never bet money you need for living expenses. Your bankroll is your trading capital — treat it with the same discipline a business owner treats their working capital.

Unit-Based Staking

Professional bettors use a unit system where 1 unit typically represents 1-2% of their total bankroll. If your bankroll is £1,000, one unit is £10-£20. This ensures no single bet can cause catastrophic damage to your capital.

Standard allocation:

• 1 unit: Standard confidence bets
• 2 units: High confidence bets (strong edge, high probability)
• 0.5 units: Value plays (lower probability but excellent odds)

The Kelly Criterion

For those who want a mathematically optimal approach, the Kelly Criterion calculates the ideal stake size based on your edge:

Kelly % = (bp - q) / b

Where b = decimal odds - 1, p = probability of winning, q = probability of losing (1-p).

Example: If you estimate a 58% probability at odds of 1.90, Kelly says to stake 12.2% of your bankroll. In practice, most professionals use quarter-Kelly (3%) or half-Kelly (6%) to reduce volatility.

Drawdown Management

Every bettor experiences losing streaks. A model with a 56% win rate will still have losing streaks of 8-10 bets roughly once every few months. The key is having enough bankroll to weather these streaks without emotional decision-making.

A practical rule: if your bankroll drops by 30% from its peak, reduce your unit size by half until you recover. This preserves capital during cold streaks and prevents the temptation to "chase" losses with larger bets.

Tracking and Review

Record every bet: date, selection, odds, stake, probability estimate, and result. Monthly reviews of your betting log reveal patterns — maybe your football picks are profitable but your tennis picks are losing money, or your live bets underperform your pre-match picks.
