Over under betting

Over under betting is a wager on whether a sportsbook-set number in an event will end up above or below that figure.

Also called
Over–under, O/U, total
Applies to
Combined score of two teams or other numerical event totals
Example lines
10.5 (MLB), 44.5 points (NFL), 210 points (NBA), 2.5 goals (football) 2

Key points

  • You bet over if the actual total will exceed the posted line, or under if it will fall below it.1
  • If the actual total exactly matches the line, the bet is a push and your stake is refunded.2
  • Over/under is also called the total market and is offered on many sports, not just match scores.3

Example: Over/under 2.5 goals in football

A bookmaker sets the total at 2.5 goals for a match. You bet over. The final score is 2–1 (3 goals total). You win. If the match ends 1–1 (2 goals total), you lose. If the line were exactly 3 and the match ended 2–1, the bet would be a push and your stake refunded.4

Common questions

How does over under betting work?

The sportsbook posts a number called the line or total. You choose over if you think the actual combined score will be higher, or under if you think it will be lower. If the actual total matches the line exactly, the bet is a push and your stake is returned.1

What is a push in betting over/under?

A push happens when the actual total equals the posted line. For example, if the line is 44.5 points and the final score is 24–20 (44 total), the bet is a push. Your stake is refunded and no profit or loss occurs.2
