No Vig Fair Odds Calculator
Sportsbook lines always include a margin, so the odds you see are shaded against you. Removing that vig reveals the fair odds, the price that reflects the market consensus probability with no house edge, which sharp bettors use as a benchmark to judge whether any other book is offering value. This calculator takes both sides of a two way market, normalises their implied probabilities to sum to exactly 100 percent, and returns the no vig fair probability and fair decimal and American odds for each side. Comparing a books actual price to these fair odds tells you instantly if a line is beatable. Enter American or decimal odds for both sides to devig the market. All math runs in your browser.

Frequently asked questions
What does removing the vig do?
It strips the sportsbook margin from a two-way market so you see each side true fair odds and the win probability without the book built-in edge.
How does it compute fair odds?
It normalizes both implied probabilities so they sum to 100 percent, then converts each fair probability back into odds; those are the no-vig prices.
Why compare fair odds to the market?
The no-vig price approximates a true probability, so lining it up against another book price helps you judge whether a bet is offered above or below fair value.
