No-Vig Fair Odds Calculator
Enter the two-way American odds for any market. We strip the sportsbook's vig and return the fair implied probability and true no-vig price for each side — the same devig math sharp bettors use to find +EV bets.
What is devigging?
Every sportsbook builds a margin (the vig or juice) into its odds so the two sides of a market add to more than 100%. A standard -110 / -110 spread implies 52.38% on each side — a total of 104.76%, meaning ~4.76% of vig. Devigging removes that margin so the two probabilities sum to exactly 100%, giving you the market's fair estimate of each outcome.
Why Pinnacle is the sharp anchor
Pinnacle runs the tightest market in sports betting (roughly 2% margin on major markets) and takes sharp action instead of limiting it. That combination makes their devigged line the closest thing to a true fair-value price. When another book prices a side better than Pinnacle's no-vig number, that's a +EV bet — the exact edge our AI top picks engine searches for across 10 books.
The devig formula
- Convert each American price to implied probability.
- Add the two probabilities to get the total (usually 1.02–1.06).
- Divide each probability by that total — the results now sum to 1.00.
- Convert the fair probabilities back to American odds for your true no-vig line.
