While the flashing lights of the casino floor attract millions, sports betting has exploded into a massive global industry.

You can be the greatest sports analyst in the world, capable of predicting upsets perfectly, and still go completely broke.

Understanding Betting Units

Professional sports bettors never talk about how many actual dollars they bet; instead, they exclusively use the term ‘units’.

When a professional says they are up ‘5 units’ for the week, it means their bankroll has grown by exactly 5%.

• By betting a flat 1% unit, you can theoretically lose 100 bets in a row before going completely broke, allowing you to survive massive variance
• Using units allows bettors with completely different financial backgrounds to compare their success accurately and fairly
• When starting out, calculate your unit size once at the beginning of the season and absolutely refuse to change it until the season ends

Navigating the Bookmaker’s Advantage

You cannot effectively manage what you do not measure; recording your wins, losses, and odds is absolutely mandatory.

When you bet on a standard point spread, you usually have to risk $110 to win $100 (odds of -110).

By rigidly adhering to proper unit sizing and aggressive tracking, you protect your money from the unpredictable chaos of live sports.
