No-vig fair odds calculator

Enter both sides of a two-way bet (spread, total or moneyline) in American odds. The calculator removes the bookmaker's margin (the "vig") and shows the fair odds and each side's true win chance.

How it works

A book's two prices add up to more than 100% implied probability; the excess is its margin. We remove it with the Shin method, which accounts for books shading longshots more than favorites. It's the same method PickSharp uses on Pinnacle's lines to find edges: when a US book offers a better price than the fair price, the bet is +EV.

Next: check a price against fair with the EV calculator, or see today's fair prices for every game.
