No-Vig Calculator
A no-vig calculator converts both sides of a two-outcome market to implied probabilities, then normalizes them so they sum to 100%. The results are fair-market estimates under the multiplicative method, not objective true probabilities. Use the same sportsbook, market, and timestamp for both prices to avoid a distorted calculation.

Sportsbooks build a margin (the vig) into their odds, so implied probabilities add up to more than 100%. This calculator removes the vig from a two-way market to show true probabilities and fair (no-vig) odds—essential for spotting value and comparing lines.
Enter American odds for each side. You'll see market vig, no-vig probabilities, and fair odds for both outcomes.
No-Vig (Vig Remover)
Enter both sides’ American odds to see no-vig probabilities and fair odds.
Frequently asked questions
What does removing the vig mean?
It removes the bookmaker margin from a complete market’s implied probabilities so the adjusted outcomes sum to 100%.
Are no-vig probabilities true probabilities?
No. They are fair-market estimates under a chosen margin-removal method, not guaranteed forecasts.
Can I use this for a soccer 1X2 market?
Use the dedicated 3-way no-vig calculator because a draw is a third mutually exclusive outcome.
