Guide
Everything you need to use this tool with confidence.
The No-Vig calculator removes the bookmaker's margin from a market and shows you the fair probabilities as well as the fair odds for each outcome.
Bookmakers build a profit margin into every set of odds. As a result, the implied probabilities are artificially inflated and usually add up to more than 100 %.
If you want to understand whether an offered price contains value, calculating fair odds is one of the most important steps of all.
Got the fair price? Drop it into the EV Calculator to see if your bet beats it — then log the bet in the Bet Tracker.
