Hold Calculator

Enter both sides of any market and this hold calculator shows the sportsbook hold percentage instantly, so you see the margin baked into the line before you bet. It handles two-way and three-way markets, which matters for soccer and hockey where the draw is priced separately, something many hold tools cannot do.

How to Use This Hold Calculator

Reading a market takes three steps:

1. Enter the odds for every outcome, both sides of a two-way market or all three prices in a three-way market, in American or decimal format.
2. Read the hold percentage the calculator returns. That is the share of every dollar wagered the sportsbook expects to keep.
3. Compare it against a benchmark. Use the common hold percentages table below to judge whether the number is sharp, standard or steep.

The result updates as you change any price, so you can test how a better number lowers the total hold.

What is Sportsbook Hold

Sportsbook hold, also called the betting margin, is the margin built into a betting market. To find it, sum the implied probabilities of every outcome and subtract 100. Whatever is left above 100 is the hold, the percentage of total money wagered the book keeps once the action is balanced.

Here is the worked example. A standard market prices both sides at -110. Each -110 price implies a 52.38% chance, and 52.38 plus 52.38 is 104.76. Subtract 100 and the hold is 4.76%. That is the house margin on a typical two-way line.

Hold is closely related to vig, the commission a book charges on a bet, but the two are calculated differently. If you want the per-bet commission rather than the whole-market margin, use our vig calculator. To turn any single price into its chance of winning, the implied probability calculator does that one step.

How to Find Low Hold Betting Markets

Finding low hold markets is the single most practical use of this tool, because a lower hold means a better price and a lower bar to turn a profit. Here is what counts as low hold and where to look.

Start with the number. Under 3% is a sharp, low hold line, and the standard -110 market is 4.76%. Reduced juice books price main markets at -105 a side, just 2.44% hold. Over 7% is high hold, worth walking away from.

Then look at the right markets. Main markets, moneylines, spreads and totals, carry far lower hold than derivatives. Player props typically run 6 to 10%, and same game parlays can hide 10 to 20% hold. If you want low hold bets, the main lines are where they live.

Finally, build your own low hold line by shopping. Taking the best price on each side across two books can synthesise a lower hold than either offers alone. The synthetic low-hold lines table below shows how two 4.76% books combine into a 3.14% line, and hold tightens closer to kickoff as volume arrives. For arbitrage, the arbitrage calculator goes further.

How to Calculate Sportsbook Hold

The calculation is the same every time, and you can do it by hand.

• Convert each price to its implied probability. A -110 price is 110 divided by 210, or 52.38%.
• Add the implied probabilities of every outcome in the market.
• Subtract 100 from the total. The remainder is the hold percentage.

Worked example: a three-way soccer market priced at +150, +240 and +180 converts to 40.00%, 29.41% and 35.71%. Those sum to 105.12, so the hold is 5.12%. The same three-step method works for any number of outcomes, which is why it handles three-way markets as cleanly as two-way ones.

Common Hold Percentages in Sports Betting

Use these benchmarks to judge any number the calculator returns. Every figure is calculated directly from the listed odds.

The pattern is clear. Main markets give the lowest hold, props sit at the high end. A 9.04% hold keeps nearly a dollar in twenty before the bet is graded, which is why disciplined bettors lean on low hold main markets.

Why Hold Matters in Sports Betting

Hold is the headwind every bet fights against. The higher it is, the more often you must win to break even, which is why the same pick can profit at one book and slowly lose at another.

Impact on Break-Even Win Rate

Hold translates directly into the win rate you need to break even. The benchmarks below show how the bar rises as the price gets worse.

At a standard -110 line you need to win 52.38% of your bets to stay level. Shave the price to -105 and the bar drops to 51.22%. Over a season, that gap is often the difference between a winning and a losing record.

Creating Synthetic Low-Hold Lines

You do not have to accept the hold a single book offers. By taking the best price on each side across different books, you can build a synthetic line with a lower combined hold than any one book posts.

Taking -105 on one side and -108 on the other produces a 3.14% hold, lower than any single book here. This is line shopping in action; pair it with our current sportsbook promos. Strip the margin from a shopped line with the no vig fair odds calculator.

Hold Calculator for Different Bet Types

Hold behaves differently across bet types, and the calculator handles all of them.

Moneyline Hold

Two-way moneylines are the simplest case, two prices summed and reduced to a hold. Three-way moneylines in soccer and hockey add the draw as a third outcome, which the calculator prices in the same step.

Spread and Total Hold

Spreads and totals are almost always two-way markets near -110 a side, so they cluster around the 4.76% standard hold. Shopping the number is the main way to beat it.

Prop Bet Hold

Player props carry the highest hold on the board, commonly 6 to 10%. Tighter markets and lower limits let books charge more, so props are where hold does the most quiet damage to a bankroll.

Advanced Hold Concepts

Two ideas sharpen how you read hold. First, hold is a market property, not a per-bet fee, so your expected loss depends on which side you take and at what price. Second, the number assumes a balanced book; if the action is lopsided the realised hold can differ. For comparing prices across books, the theoretical hold is the right yardstick.
