What is Sportsbook Hold?
A hold calculator is a free betting tool that calculates the margin (hold) that sportsbooks build into betting markets. Also known as the "house edge" or "vigorish," hold represents the bookmaker's guaranteed profit margin assuming balanced action on all outcomes.
Our enhanced visual hold calculator features an animated gauge display, probability pie chart, and color-coded quality ratings. See exactly how much edge the sportsbook has with instant visual feedback that makes understanding betting margins intuitive.
How to Calculate Sportsbook Hold
The Hold Calculation Process
Hold reveals the bookmaker's edge built into the odds:
1. Convert all odds to implied probability
2. Sum the probabilities: P1 + P2 (+ P3 for 3-way)
3. Hold = (Total - 100%)
Example: -110/-110 odds
Each side = 52.38% probability
Total = 104.76%
Hold = 4.76%
Understanding the Visual Gauge
Our hold gauge provides instant visual feedback:
- Green Zone (0-2.5%): Excellent value - sharp book territory
- Light Green (2.5-4%): Very good - competitive odds
- Yellow (4-5%): Average - standard US sportsbook
- Orange (5-7%): Below average - consider shopping
- Red (7%+): Poor value - high margin market

Why Hold Matters in Sports Betting
Impact on Break-Even Win Rate
Hold directly affects how often you need to win to profit:
50% wins to break even
51.22% wins to break even
52.38% wins to break even
55% wins to break even
Finding Low-Hold Markets
Strategies for minimizing hold exposure:
- Line Shopping: Compare odds across multiple sportsbooks
- Sharp Books: Use reduced-juice sportsbooks when available
- Main Markets: Stick to spreads, totals, and moneylines
- Avoid Parlays: Multi-leg bets compound the hold
- Time Your Bets: Hold often decreases closer to game time
Creating Synthetic Low-Hold Lines
By shopping across sportsbooks, you can create artificially low hold:
Example: NFL Spread Shopping
| Sportsbook | Team A | Team B | Hold % |
|---|---|---|---|
| Book 1 | -110 | -110 | 4.76% |
| Book 2 | -105 | -115 | 4.88% |
| Book 3 | -108 | -108 | 3.92% |
| Best Line | -105 (Book 2) | -108 (Book 3) | 3.00% |

Frequently Asked Questions
What is sportsbook hold?
Sportsbook hold is the margin or edge built into betting odds. It's calculated by summing the implied probabilities of all outcomes and subtracting 100%. Our visual calculator shows this as an animated gauge - lower hold (under 4%) means better value for bettors, while higher hold gives the sportsbook a bigger edge.
How do you calculate betting hold percentage?
To calculate hold: 1) Convert all odds to implied probability, 2) Sum the probabilities, 3) Subtract 100%. For example, -110/-110 odds each imply 52.38% probability, totaling 104.76%, giving a hold of 4.76%. Our calculator displays this visually with an animated gauge and probability pie chart.
What is a good hold percentage for bettors?
Good hold percentages are under 4% (shown in green on our gauge). Sharp sportsbooks offer 2-3% hold, standard books charge 4-5% (yellow), while props and parlays often have 7-10% hold (red). Our visual rating system instantly shows whether you're getting good value or should shop for better lines.
What's the difference between hold and vig?
Hold and vig are related but slightly different. Hold is the bookmaker's margin on the entire market (all outcomes combined), while vig traditionally refers to the commission on losing bets. Both measure the sportsbook's edge. Our calculator shows hold percentage with visual indicators for easy understanding.
How can I find low hold betting markets?
Find low hold markets by: 1) Line shopping across multiple sportsbooks, 2) Using reduced juice books (-105 lines = 2.44% hold), 3) Focusing on main markets (spreads/totals), 4) Avoiding props and parlays. Our visual calculator helps identify excellent value markets with its color-coded gauge system.
