Bankroll management is the single most important skill in sports betting. Even bettors with a genuine edge will go broke without proper money management. It is the difference between a sustainable hobby and a financial disaster.
Setting Up Your Bankroll
Your betting bankroll must be money you can afford to lose completely. It should be:
- Separate from personal finances — use a dedicated account or e-wallet
- Fixed at a specific amount — do not top it up after losses
- Appropriate for your financial situation — £100 is fine; £10,000 is fine if disposable
Choosing Your Unit Size
Your unit size is the standard amount you stake on each bet. The most common approach:
| Risk Level | Unit Size | Bankroll £1,000 | Bets Before Bust (Worst Case) |
|---|---|---|---|
| Conservative | 1% | £10 | 100 |
| Standard | 2% | £20 | 50 |
| Moderate | 3% | £30 | 33 |
| Aggressive | 5% | £50 | 20 |
Staking Plans
Flat Staking
Bet the same amount every time regardless of odds or confidence. Simple, effective, and removes emotional decision-making. This is the best approach for 90% of bettors.
Percentage Staking
Bet a fixed percentage of your current bankroll. As your bankroll grows, stakes grow; as it shrinks, stakes shrink. This automatically adjusts risk but requires recalculating before each bet.
Kelly Criterion
Mathematically optimal stake sizing based on your estimated edge. Powerful but requires accurate probability estimates. Most bettors who use Kelly apply a fractional version (Quarter or Half Kelly).
Tracking Your Bets
Record every bet with:
- Date, sport, market, selection
- Odds, stake, result
- Running profit/loss
After 200+ bets, analyse your data. Which sports are profitable? Which bet types? What odds ranges work best? Without tracking, you cannot improve.
Surviving Losing Streaks
A bettor with a 55% win rate on even-money bets will experience:
- A 5-bet losing streak roughly once every 30 bets
- A 10-bet losing streak roughly once every 1,000 bets
- A 15-bet losing streak roughly once every 30,000 bets
These are not signs of failure — they are mathematical certainties. Your unit size must be small enough to survive them.
When to Adjust
Recalculate your unit size monthly or after every 100 bets. If your bankroll has grown, increase your unit proportionally. If it has shrunk, decrease it. This protects against ruin while allowing winners to compound.
