The vig at +110

If both sides of a two-way market were priced at +110, the implied probabilities would add up to -4.76% above 100%. That excess is the overround, or vig; as a share of stakes it is a -5.00% margin for the bookmaker. Removing it leaves fair odds of 2.00 decimal ( +100) on each side. Use the devig calculator to do the same for any market.
