Understanding Bookmaker Margins
What Is Margin?
The margin (or vig/juice) is the bookmaker’s built-in profit. It’s the difference between true probability and the odds offered, ensuring the house always has an edge.
How Does It Affect You?
A higher margin means worse odds for you. On a 5% margin market, you’re effectively paying $5 per $100 wagered just for the privilege of betting.
Why Low Margins Matter
Over hundreds of bets, margin compounds significantly. Moving from a 6% to 2% margin bookmaker can be the difference between profit and loss long-term.
