Frequently Asked Questions
How do you calculate no-vig odds?+
Convert each outcome's odds into implied probability, then remove the bookmaker's overround so the market totals 100%. Convert those no-vig probabilities back into fair odds.
What is a devig calculator?+
A devig calculator removes the bookmaker's built-in margin, also called vig or overround, to estimate the market's fair probabilities and fair odds.
Which no-vig method should I use?+
Proportional devig is a good default for most markets because it scales each outcome's implied probability by the same share of the overround. Additive and power methods use different assumptions about how the margin is distributed, which can be useful for uneven or heavily skewed markets.
