How To Manage Your Sports Betting Bankroll

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


Without strict bankroll management, an inevitable bad streak of unexpected injuries or bad referee calls will wipe out your entire account.

The Concept of the 'Unit'

A 'unit' is simply a standard percentage of your total starting bankroll, usually representing exactly 1% or 2%.


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 varianceUsing units allows bettors with completely different financial backgrounds to compare their success accurately and fairlyWhen 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.


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

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