An implied probability of 50.98% makes -104 a near-even price. This is the natural home of handicap and over/under markets, where the bookmaker adjusts the line rather than the price and both sides are quoted a shade under 2.00 decimal.

The vig at -104

If both sides of a two-way market were priced at -104, the implied probabilities would add up to 1.96% above 100%. That excess is the overround, or vig; as a share of stakes it is a 1.92% 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.
