Over/Under (Totals)

An over/under bet, also called a totals bet, is a wager on the combined final score of both teams in a game. The sportsbook posts a projected total, and you decide whether the actual combined score finishes over (above) or under (below) that number. You don’t have to pick a winner — only whether the game runs high-scoring or low-scoring relative to the posted line.

Oddsmakers set over/under lines using historical data, team stats, weather, pace of play, and other scoring drivers. Like point spreads, totals usually post at -110 on both sides, though the odds can drift slightly as action comes in. The total itself can also move up or down with betting volume or late news like injuries.

Example

An NBA game between the Los Angeles Lakers and the Golden State Warriors has a posted total of 224.5. Bet the over and a final of Lakers 118, Warriors 112 (combined 230) cashes, since 230 tops 224.5. If instead it ends Lakers 105, Warriors 108 (combined 213), the under hits because 213 falls below 224.5.

At 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 are all about total points, which is great when you have a read on a game’s pace or style but no strong lean on who wins.
• Half-point totals kill pushes: Totals ending in .5 force a clean result. Whole-number totals (like 44) can push if the combined score lands exactly there.
• Goes beyond full-game totals: Many books post over/unders on team totals, half-time totals, quarter totals, and even player props like points scored or passing yards.
• Weather and pace drive it: Outdoors, 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.
