Over/Under (Totals)
A wager on whether the combined score of a game will finish over or under a posted number.
An over/under bet, also called a totals bet, is a wager on the combined final score of both teams in an event. The sportsbook posts a projected total, and bettors decide whether the actual combined score will land over (above) or under (below) that figure. This wager does not require picking a winner — only whether the game will be high-scoring or low-scoring relative to the posted line.
Over/under lines are priced by oddsmakers using historical data, team statistics, weather, pace of play, and other scoring drivers. As with point spreads, totals are typically offered at -110 on both sides, though the odds can drift slightly as action comes in. The total itself may also move up or down in response to betting volume or late information such as injury news.
Example
An NBA game between the Los Angeles Lakers and the Golden State Warriors carries a posted total of 224.5. If you bet the over and the final score is Lakers 118, Warriors 112 (combined 230), your bet wins because 230 exceeds 224.5. If instead the final is Lakers 105, Warriors 108 (combined 213), the under wins because 213 is below 224.5.
Assuming standard -110 odds, a $110 wager on the over returns $100 profit plus your $110 stake when the combined score clears 224.5.
Key Points
- No winner required: Over/under bets target total points scored, making them useful when you have a read on the pace or style of a game but no strong lean on the winner.
- Half-point totals prevent pushes: Totals ending in .5 force a decisive result. Whole-number totals (such as 44) can push if the combined score lands exactly on the number.
- Extends beyond full-game totals: Many books offer over/under lines on team totals, half-time totals, quarter totals, and player-level statistical totals such as points scored or passing yards.
- Weather and pace are key drivers: In outdoor sports, wind, rain, and cold suppress scoring. In basketball, fast-tempo teams tend to push totals higher.
- Overtime counts: Unless stated otherwise, overtime scoring is typically included in the final total for settlement.
