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

Treating your betting funds like a professional investment portfolio is the only way to survive the long, grueling sports season.

The Concept of the ‘Unit’

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

Tracking Your Bets and Understanding the Vig

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

That extra $10 is the bookmaker’s fee, and it means you must win exactly 52.38% of your bets just to break even mathematically.

Sports betting should be viewed as a slow, methodical grind, not a get-rich-quick scheme.
