No-Vig Odds Converter

Remove the bookmaker's margin to find the true probability of outcomes

What are No-Vig Odds?

Bookmakers build a profit margin (vigorish or "vig") into their odds, which means the implied probabilities of all possible outcomes add up to more than 100%. No-vig odds remove this margin to show what the odds would be in a perfectly efficient market.

No-vig odds are useful for:

Finding the "true" probability of outcomes according to the market
Comparing odds across different bookmakers
Identifying value betting opportunities
Creating power ratings and predictive models

Market Type

2-Way Market (e.g., Moneyline, Spread)

3-Way Market (e.g., Soccer 1X2)
