No-Vig Odds Calculator
Remove the bookmaker margin from a two-outcome market and calculate normalized fair probabilities and decimal odds.
Formula
Fair probability_i = (1/odds_i) / sum(1/odds); fair odds_i = 1/fair probability_i.
About the No-Vig Odds Calculator
Remove the bookmaker margin from a two-outcome market and calculate normalized fair probabilities and decimal odds. This tool keeps the requested measurements separate and applies the named method instead of substituting an unrelated general estimate.
How the No-Vig Odds Calculator Works
Each decimal price is converted to implied probability, the overround is measured, and both probabilities are normalized to sum to one.
Formula
Fair probability_i = (1/odds_i) / sum(1/odds); fair odds_i = 1/fair probability_i.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs
- Outcome one decimal odds (required).
- Outcome two decimal odds (required).

Accuracy and Limitations
This proportional method is one margin-removal model and does not predict the event. Prices can move, and betting involves risk.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
