No-vig odds
and hold
Enter every side of one market from the same site. You'll see how much the site keeps and what the fair price would be without it.

How it works
Each price is turned into the win chance it implies. Added up, they come to more than 100%: that extra is the overround. Dividing each side's chance by the total spreads the cut evenly and leaves fair chances that add to 100%. The hold is 1 minus 1 divided by the total, which is the share of all money staked the site expects to keep if action is balanced.
Use the fair price from a sharp, high-volume market as a yardstick. If another site, or a social sportsbook, offers better than that fair price, the EV calculator shows what it's worth.
Questions
What is vig (or juice)?
The cut a site builds into its prices. If both sides of a game are -110, the implied chances add up to 104.76%. The extra 4.76% is the overround, and the hold (what the site keeps on balanced action) is about 4.55%.
What are no-vig or fair odds?
The prices you get after removing the cut so the chances add up to exactly 100%. This calculator uses the proportional method: each side’s implied chance divided by the total.
What is a good hold?
Lower is better for players. Two-way main lines at many sites sit around 4% to 5%. Props, parlays and futures are often far higher. Exchanges and prediction markets charge fees instead of a built-in margin.

These calculators do math, not predictions. No price is a sure thing: sites can change lines, cancel picks made at a wrong price, limit accounts, or close markets before you place the other side.
