Look at almost any point spread and you’ll see the same two numbers hanging off each side: -110. Whichever team you like, you’re laying $110 to win $100. That gap between what you risk and what you win is the vig — sometimes called the juice — and it’s the sportsbook’s built-in fee for taking your bet. Most bettors know it exists. Fewer stop to think about what it actually means for their long-term results.
Here’s the math that matters: at standard -110 pricing, you need to win 52.4% of your bets just to break even, not 50%. That 2.4% gap is the house’s edge before you’ve made a single decision. It doesn’t sound like much on one bet, but stretched across a full season of picks, it’s the difference between a winning year and a losing one for a bettor who’s otherwise calling the games correctly at a coin-flip rate.
The number moves with the odds, too. Lay -120 instead of -110 and your breakeven climbs to roughly 54.5%. Find a book offering -105, and it drops closer to 51.2%. This is part of why line movement is worth watching beyond just which way a number is trending — the price attached to that number changes how much you actually need to be right.
The practical habit worth building: before you place a bet, glance at the odds on both sides, not just the spread or total itself. If one book has a game at -110/-110 and another has it at -105/-115, that’s not a wash — it’s a real difference in what you need to hit to turn a profit over time. Shopping for the better number costs you nothing, and it pays out over a long enough sample.
None of this replaces doing the work on the actual matchup — it just means the price you’re getting matters as much as the pick itself. Our team builds win-rate expectations with that vig baked in from the start, which is part of why professional handicapping analysis tends to hold up better over a full season than gut-feel picks: it’s accounting for the house’s cut before a single number ever gets locked in.
