What is Sportsbook Hold?
Sportsbook hold—also called margin, overround, or house edge—is the percentage of total handle the book expects to retain when wagers balance across outcomes. It reflects the built-in margin in posted odds—lower hold means better prices for bettors.
This free hold calculator works on spreads, moneylines, totals, soccer 1X2, and other multi-outcome markets. Compare books, spot soft lines, and avoid high-margin traps.
Overround is the sum of implied probabilities from posted odds (often above 100%). Hold % is that excess: (overround − 100%). They describe the same margin from different angles.

What's Next?
Now that you know the hold: 1. Compare vig and fair prices on 2-way lines with our vig calculator; 2. size your edge with the expected value calculator.
How to Use This Hold Calculator
Choose 2-, 3-, or 4-way market type, then enter all posted prices. Odds format follows your site preference (decimal, American, fractional, etc.).
- Outcome #1 Odds: First outcome—example: -110 on the favorite in a spread.
- Outcome #2 Odds: Second outcome—example: -110 on the underdog.
This calculator shows:
- Hold % (sportsbook margin / overround on the posted market)
- Implied probability for each outcome
Note: Lower hold means better long-term prices. Most US spreads sit near 4–5% hold at -110/-110; props, parlays, and soccer 1X2 often run 6%+ unless you have a strong edge.
Tips & Best Practices
- Compare hold % across books on the same fixture before placing a bet.
- Hold and vig measure related margin concepts—use both tools when evaluating a line.
- Avoid markets with hold above 6% unless your model shows a large edge.
- For 3-way soccer, select 3 Way and enter home, draw, and away prices.
- Reduced-juice promos (-105 lines) materially improve break-even win rates.
- NFL/NBA main spreads often sit near 4–5% hold; player props frequently run 6%+.
Why Hold Varies by Market Type
Main NFL/NBA spreads and totals attract the most volume and line-shopping—books compete on price, so hold often sits near 4–5%. Player props, futures, and niche markets carry more uncertainty and less balanced action, so hold frequently runs 6–15%+. Always compare hold on the exact market you plan to bet.
How Sportsbook Hold Works in Betting Markets
For decimal odds O₁…Oₙ, implied probability for outcome i is pᵢ = 1/Oᵢ. Hold % = (Σpᵢ − 1) × 100%. On a balanced two-way market at -110/-110, each side implies ~52.38%, totaling ~104.76%—about 4.76% hold.
Hold is closely related to vig (overround) on posted lines but describes the book's expected profit when action balances. Use this tool to compare sportsbooks on the same fixture.
For decimal odds \(O_1, \ldots, O_n\) on any market:
Hold % = \(\bigl(\sum_i \frac{1}{O_i}-1\bigr)\times 100\). Implied prob for side \(i\): \(p_i = 1/O_i\).
Hold Calculation Examples
-110 / -110 Point Spread
Scenario: Both sides at -110 (decimal 1.91 each). Select 2 Way and enter those prices above.
| Metric | Value | Note |
|---|---|---|
| Implied prob each side | 52.38% each | 1/1.91 per side |
| Hold (overround) | 4.76% | Typical US spread margin |
| 3-way soccer example | 3-way 1X2 | Use 3 Way—hold often 6%+ on 1X2 |
Each -110 implies 52.38% → total 104.76% → 4.76% hold. If one book shows -105 and another -110, the -105 book has lower hold.
3-Way Soccer 1X2 (+120 / +220 / +180)
Home +120 (2.20), draw +220 (3.20), away +180 (2.80). Implied: 45.45% + 31.25% + 35.71% = 112.41% → 12.41% hold. Soccer match odds often carry higher hold than NFL spreads—shop multiple books.
4-Way Golf Matchup (+150 / +200 / +300 / +400)
Four golfers at +150 (2.50), +200 (3.00), +300 (4.00), +400 (5.00). Implied: 40% + 33.33% + 25% + 20% = 118.33% → 18.33% hold. Select 4 Way in the calculator to verify.
Break-Even Win Rate: Why Lower Hold Matters
At -110/-110 (~4.76% hold), you must win ~52.4% of bets to break even. At -105/-105 (~2.38% hold), break-even drops to ~51.2%—material over thousands of wagers.
| Line | Hold | Break-even win rate |
|---|---|---|
| -110 / -110 | ~4.76% | 52.4% |
| -105 / -105 | ~2.38% | 51.2% |
Hold vs Vig: Know the Difference
Vig (overround) measures how far implied probabilities exceed 100% on posted odds. Hold describes expected book profit when action balances—related but not identical. Our vig calculator adds no-vig fair prices for 2-way markets.
Recommended Workflow
1. Calculate hold on the posted line with this tool.
2. Check implied probability per side with our implied probability calculator.
3. For 2-way markets, compare vig and fair prices on the vig calculator; size edges with the EV calculator.
