Calculate the sportsbook's built-in edge (vig/juice)
| Market Type | Typical Hold | Example Odds |
|---|---|---|
| NFL Spreads/Totals | 4-5% | -110 / -110 |
| NBA Spreads | 4-5% | -110 / -110 |
| MLB Moneylines | 3-5% | -130 / +120 |
| Player Props | 5-10% | -115 / -115 |
| Parlays | 10-30%+ | Varies |
| Futures | 15-40% | Multiple outcomes |
Hold (or vig/juice) is the sportsbook's built-in profit margin. It's the difference between the true probability and the odds they offer. Lower hold = better value for bettors.
Compare hold percentages across sportsbooks for the same market. A book with 4% hold is better than one with 6% hold on the same game.
Props, parlays, and futures typically have much higher hold. This makes them harder to beat long-term. Stick to main markets (spreads, moneylines, totals) for better value.
