Bettors who want to understand what they're actually paying to bet at the operator — the difference between winning bettors and losing bettors is often built here.
Definition
Hold rate — also called vig, juice, or margin — is the sportsbook's expected profit as a percentage of total handle on a given market. A -110/-110 market carries approximately 4.55% hold; the operator expects to keep 4.55 cents of every dollar wagered.
Calculating hold on a -110/-110 line
Both sides priced at -110. Implied probability of each = 110/210 = 52.38%. Total implied probability = 104.76%. Hold = 104.76% - 100% = 4.76%. Round to 4.55% at the more common -108/-108 pricing. This is the operator's guaranteed edge if action is balanced perfectly on both sides.
Typical values in real markets
| Context | Range |
|---|---|
| NFL sides (regulated) | 4.5-5.0% |
| NFL sides (offshore best) | 4.4-4.6% |
| Alt lines | 5.5-8.0% |
| Player props | 7-12% |
| Same-game parlays | 12-25% |
| Live betting | 5.5-7.5% |
These ranges are drawn from real markets sampled across the operators we cover. They're typical values — outliers exist in both directions, particularly on smaller or less-liquid markets.
Why this matters
Lower hold means better bettor prices, which means better bettor ROI. The difference between betting at a 4.5% hold book versus a 5.5% hold book, across 500 bets per year, adds up to thousands of dollars for a volume bettor.
Frequently asked questions
How is Hold Rate at a Sportsbook different from related concepts?
The concept above is one of several closely-related ideas in betting math. Understanding the distinctions between them — and when each applies — is a foundational skill for any bettor evaluating their own play or an operator's pricing.
Can I calculate this myself?
Yes. All the math shown in the worked example is straightforward arithmetic once you know the formula. Most bettors don't need to calculate it manually for every bet — spreadsheets or dedicated tools handle the volume — but understanding the mechanics helps you spot when a price looks off.
Where should a beginner start?
Read the definition and the worked example, then apply the concept to your last 10 bets to see how it changes your view of your results. Concept comprehension deepens fastest when you apply it to real historical data.
Do offshore and regulated books treat this differently?
The underlying math is the same across all books. What differs are the specific values — hold rates, rollover multipliers, edge margins — that appear in real markets. Our operator reviews document those differences.
