Over/Under Betting Guide: How to Bet Totals (Examples Included)
Last updated:
An over/under bet — also called a total — has nothing to do with who wins. You bet on the combined score of both teams, choosing whether it will finish over or under a number the book sets.
This guide covers how totals are priced, how pushes and half-points work, and the situational factors — pace, weather, injuries — that move a total before kickoff.
What an over/under bet is
The total is the book’s projection of the combined final score. If an NFL game has a total of 47.5, an over bet wins when the two teams combine for 48 or more points, and an under wins at 47 or fewer.
Like spreads, totals usually carry a half-point to avoid ties, and both sides are priced near -110. When the total is a whole number, an exact landing is a push and your stake is refunded.
How totals are priced and moved
Books set the total from team scoring rates, pace, and matchup, then price both sides around -110. As bets come in, they nudge the number: heavy over money on 47.5 might push the total to 48 or shift the over to -115.
External factors move totals fast. A star quarterback ruled out, a windy forecast, or a backup goalie can drop a total by multiple points within hours, so the number you bet and when you bet it both matter.
Convert -110 to implied probability — about 52.4% — and you can see the hold baked into each side. Shopping for -105 or a better half-point lowers that cost.
Example bet walkthrough
You bet the over 47.5 in a Chiefs–Bills game at -110, staking $55 to win $50. The teams combine for 51 points, so the over hits and you collect $50 profit plus your $55 stake.
Had the final landed at 45 total points, the under would have won and your over bet would lose. On a whole-number total of 47, a combined 47 would have been a push, refunding your stake.
If a second book offered over 47 at -110, that half-point would win you games that land on exactly 47 or 48 — another reason to compare totals across books.
Over/under strategy tips
Totals reward bettors who read the situation, not the scoreboard:
- Weight pace and style. Fast, up-tempo teams push totals up; defensive, ball-control teams push them down. The matchup matters more than either team alone.
- Track weather in outdoor sports. Wind and rain suppress scoring in football and baseball, often before the book fully adjusts.
- Watch late injury news. A scratched scorer or a backup pitcher can swing a total several points — bet before the line catches up.
- Mind half-points and key totals. In low-scoring sports, a half-point on the total is worth shopping for.
- Resist betting overs just because they are more fun — books know the public loves the over and shade prices accordingly.
Best sportsbooks for totals
For totals, you want sharp numbers and deep alternate-total menus:
- DraftKings — broad alternate-total coverage and quick reactions to injury and weather news.
- BetMGM — competitive totals across secondary leagues, where softer numbers are easier to find.
- Caesars — frequently offers reduced juice on marquee totals, lowering your long-run cost.
Common totals mistakes
Two habits cost totals bettors the most:
- Defaulting to the over. The public’s over bias means over prices are often shaded; the value is frequently on the under.
- Ignoring late news. Totals move on injuries and weather faster than almost any other market, so betting stale information is a guaranteed leak.
Frequently asked questions
- What does over/under mean in betting?
- It is a bet on the combined score of both teams, not the winner. You bet whether the total points will go over or under the number the sportsbook sets.
- What happens if the total lands exactly on the number?
- If the combined score equals a whole-number total, the bet is a push and your stake is refunded. Half-point totals like 47.5 cannot push.
- Do overtime and extra innings count toward the total?
- Yes. Unless a book states otherwise, totals include all overtime, extra innings, or extra time, which is why live unders can be risky in close games.
- Why do totals move before the game?
- Books adjust totals for betting volume, injuries, weather, and lineup news. A scratched scorer or a windy forecast can move a total several points, so timing your bet matters.
