Professional bettors don’t just look at odds; they look at the True Probability hidden behind the bookmaker’s fee (Vig). To find value, you must “Devig” the line.
This Advanced Devigger allows you to remove the margin using different mathematical models (Multiplicative or Additive) to see the fair price of a wager.

How to Devig a Line
- Input Odds: Enter the both sides of the market (e.g., -110 / -110 or 1.91 / 1.91).
- Select Method:
- Multiplicative (Standard): Assumes the margin is spread proportionally based on the odds size. This is the industry standard.
- Additive: Assumes the margin is spread equally across all outcomes.
- Result: The tool shows the Fair Odds. If you can find a bookmaker offering odds higher than this number, you have a +EV bet.
