No-Vig Calculator

Sportsbooks build vig, juice, or hold into listed odds, which makes the total implied probability across all outcomes exceed 100%.

A no-vig fair odds calculator normalizes those implied probabilities so the market totals 100%. That gives you a cleaner reference price for each side before comparing against live sportsbook prices.

Worked example, a standard two-way market at -110 on both sides. Each side implies 52.38%, so the market totals 104.76%. The vig is that 4.76% above 100. Normalize both sides back to 100% and each lands at 50.0%, a fair price of +100. You are paying -110 for a coin flip.

Worked example with an uneven market, -140 against +120. Those imply 58.33% and 45.45%, totalling 103.79%, so the hold is 3.79%. The fair prices come out at -128 and +128. If you were about to take the -140 side, that gap is what the number costs you before the event even starts.

Three-way markets, such as soccer 1X2 where a draw is its own outcome, work the same way but carry more hold because there are three prices to pad. Take +150, +230 and +180. Those imply 40.00%, 30.30% and 35.71%, totalling 106.02%, so the vig is 6.02%, noticeably above the two-way example. Fair prices are about +165, +250 and +197. Any market with more than two outcomes can be de-vigged this way, including three-way moneylines and multi-runner fields.

No-vig odds are a reference price, not a guarantee. Verify house rules, line freshness, limits, and market availability before deciding whether a listed number deserves more review.
