No-Vig Fair Odds Calculator
Normalize two opposing implied probabilities so they sum to 100%. That estimate is only as good as the posted prices.
Formula
Fair p(A) = implied(A) / (implied(A)+implied(B)). Hold = implied(A)+implied(B) − 1.
Worked examples
-110 / -110. Fair split is 50/50. Hold is about 4.76%.
FAQ
Is no-vig the true probability?
It is a market-implied estimate after removing overround, not a guarantee.
