No-Vig Fair Odds Converter
Remove the sportsbook's built-in advantage (vig) to see the true fair odds and probabilities.
Sportsbooks build in a profit margin called the "vig" or "juice" into their odds. This means the implied probabilities of all outcomes add up to more than 100%.
This calculator removes the vig by:
- Converting the odds to implied probabilities
- Calculating the total vig (how much over 100% the probabilities add up to)
- Proportionally reducing each probability so they sum to exactly 100%
- Converting the fair probabilities back to odds in all formats
The result shows you what the odds would be in a perfectly fair market with no house edge.
What is vig in sports betting?
Vig (or juice) is the commission that sportsbooks charge for taking your bet. It's built into the odds so that the implied probabilities of all outcomes add up to more than 100%, ensuring the house always has an edge.
Why should I remove the vig from odds?
Removing vig shows you the true fair market probability and odds. This helps you identify when a sportsbook's odds offer value compared to the actual likelihood of an outcome.
How accurate are no-vig calculations?
No-vig calculations are mathematically precise for the odds you input. However, they assume the sportsbook's original odds accurately reflect the true probabilities, which may not always be the case.
What's a typical vig percentage?
Most sportsbooks charge 4-5% vig on standard bets like point spreads and totals. However, vig can be much higher on prop bets, futures, and other specialty markets.
