Over/Under (Totals)
A wager on whether the combined score of a game will finish over or under a set number.
An over/under bet, also known as a totals bet, is a wager on the combined final score of both teams in a sporting 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 asks nothing about who wins — only whether the game proves high-scoring or low-scoring against the posted line.
Over/under lines are constructed by oddsmakers from historical data, team statistics, weather, pace of play, and the various other elements that shape scoring. As with point spread bets, totals are typically offered at -110 on each side, though those odds can drift slightly as action arrives. The total itself may also climb or fall in response to betting volume or late-breaking news such as an injury.
Example
An NBA game between the Los Angeles Lakers and the Golden State Warriors carries a posted total of 224.5. If you back the over and the final reads Lakers 118, Warriors 112 (combined 230), your bet wins, because 230 exceeds 224.5. If instead the final reads Lakers 105, Warriors 108 (combined 213), the under prevails, because 213 falls short of 224.5.
At standard -110 odds, a $110 wager on the over would return $100 in profit plus your $110 stake should the combined score clear 224.5.
Key Points
- No need to pick a winner: Over/under bets concern only the total points scored, which makes them attractive when you have a read on a game’s pace or style but no firm view on the outcome.
- Half-point totals prevent pushes: Totals ending in .5 guarantee a decisive result. Whole-number totals (such as 44) can produce a push if the combined score lands exactly on the figure.
- Applicable beyond full-game totals: Many sportsbooks post over/under lines on individual team totals, half-time totals, quarter totals, and even player-level stats such as points scored or passing yards.
- Weather and pace are key factors: In outdoor sports, wind, rain, and cold can dampen scoring. In basketball, fast-tempo teams tend to drive totals higher.
- Overtime counts: Unless stated otherwise, overtime scoring is normally included in the final total for settlement purposes.
