Over/Under (Totals)

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 you decide whether the actual combined score lands over (higher than) or under (lower than) that number. You never have to pick a winner — only whether the game runs high-scoring or low-scoring against the posted line.

Oddsmakers set over/under lines using historical data, team stats, weather, pace of play, and anything else that drives scoring. Like point spread bets, totals usually come at -110 on both sides, though the odds can drift as action arrives. The total itself can move up or down too, reacting to betting volume or late news like an injury.

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 the final is Lakers 118, Warriors 112 (combined 230), and your bet wins because 230 tops 224.5. If instead it ends Lakers 105, Warriors 108 (combined 213), the under cashes because 213 falls below 224.5.

At standard -110 odds, a $110 wager on the over returns $100 in profit plus your $110 stake when the combined score clears 224.5.

Key Points

• No need to pick a winner: Over/under bets ride entirely on total points, perfect when you have a read on a game’s pace or style but no strong call on who wins.
• Half-point totals prevent pushes: Totals ending in .5 guarantee a clean result. Whole-number totals (like 44) can push if the combined score lands exactly there.
• Goes well beyond full-game totals: Many books post over/under lines on team totals, half-time totals, quarter totals, and even player props like points or passing yards.
• Weather and pace are key factors: In outdoor sports, wind, rain, and cold can choke scoring. In basketball, fast-tempo teams tend to push totals higher.
• Overtime counts: Unless stated otherwise, overtime scoring is typically folded into the final total for settlement.
