No-Vig Fair Odds
Strip the bookie margin, see the real price.
Enter both sides' decimal odds to strip the margin.
How to use it
Enter the two sides of a market as decimal odds. The calculator removes the bookmaker's margin and returns the fair odds and the implied true probabilities for each outcome.
What it means
Bookmakers build a margin into their prices, so the implied probabilities add up to more than 100%. Removing that margin gives a fair-odds baseline you can compare other books against. It's a reference price, not a prediction.
