Over/Under (Totals)
A bet on whether the combined score of a game finishes over or under a set number.
An over/under bet, also called a totals bet, wagers on the combined final score of both teams in an event. The sportsbook posts a projected total, and bettors choose whether the actual combined score lands over (above) or under (below) that figure. This bet requires no winner pick — only a read on whether the game runs high-scoring or low-scoring relative to the line.
Oddsmakers set over/under lines from historical data, team statistics, weather, pace of play, and other scoring drivers. Like point spreads, totals usually carry -110 on both sides, though the price can drift as action arrives. The total itself may also move up or down on betting volume or late news such as injuries.
Example
An NBA game between the Los Angeles Lakers and the Golden State Warriors carries a posted total of 224.5. Bet the over and a final of Lakers 118, Warriors 112 (combined 230) wins, since 230 exceeds 224.5. Instead, a final of Lakers 105, Warriors 108 (combined 213) wins the under, since 213 is below 224.5.
At standard -110 odds, a $110 wager on the over returns $100 profit plus your $110 stake if the combined score clears 224.5.
Key Points
- No winner needed: Totals hinge purely on points scored, ideal when you have a read on a game’s pace or style but no firm opinion on the result.
- Half-point totals prevent pushes: Totals ending in .5 force a decisive outcome. Whole-number totals (such as 44) can push if the combined score lands exactly there.
- Beyond full-game totals: Many books post over/under lines on team totals, half-time totals, quarter totals, and player props like points or passing yards.
- Weather and pace are key factors: Outdoors, wind, rain, and cold suppress scoring. In basketball, fast-tempo teams tend to push totals higher.
- Overtime counts: Unless stated otherwise, overtime scoring is normally included in the settled total.
