Over/Under (Totals)

Over/Under (Totals)

Basic Betting

Definition

A wager on the total number of rounds or points, going over or under a line set by the bookmaker. In boxing, this usually refers to the total rounds the fight lasts.

Formula

Implied probability can be derived from odds, but no unique formula; the line is set (e.g. 7.5 rounds).

Example

For an **over/under** of 7.5 rounds, betting “Over” wins if the fight goes past midway of round 8, and “Under” wins if it ends before that point.
