Over/Under Totals Explained
What over/under bets are, how to read totals, sport-specific differences, and how line shopping totals adds up across a season.
Totals (also called over/under bets) are the third major American betting market alongside moneylines and spreads. You're not picking a winner. You're betting on how many points, runs, or goals will be scored by both teams combined.
How totals work
A totals line looks like this:
Over 218.5 (-110)
Under 218.5 (-110)
The total is 218.5 points. Bet the over and you need both teams to combine for 219 or more. Bet the under and you need them to score 218 or fewer combined. The price (-110) is the same -110 / -110 standard you see on spreads, with about a 4.8% hold built in.
Half-point totals (218.5) eliminate push risk. Whole-number totals (218) refund the bet if the combined score lands exactly on the number.
Reading the price
Like spreads, books shift the price (-110 vs -105 vs -115) before they shift the number itself. Over -110 means -110 to bet the over. If the line is Over 218.5 (-115) / Under 218.5 (+105), the book is signaling that money is heavier on the over and is paying you a premium to take the under.
To strip out the vig and see the book's actual probability split, use the no-vig calculator.
Sport-specific totals
NBA totals cluster in the 215 to 240 range in the regular season, often higher in playoff series with strong offenses. Game pace (possessions per 48 minutes), shot-quality, and three-point variance all push totals up or down.
NFL totals typically range from 38 to 55. Weather (wind especially) can move totals 2 to 4 points. Defensive injuries and offensive scheme changes are the primary movers.
MLB totals are typically 7 to 10 runs. Starting pitcher matchups dominate the line; bullpen quality, weather, and ballpark factor in.
NHL totals are typically 5.5 or 6. Goaltending matchups and recent team form dominate movement.
Soccer totals are usually 2.5 in domestic league play. Asian totals (e.g., 2.25, 2.75) split your stake between two adjacent whole numbers.
MMA round totals are usually 1.5 or 2.5 rounds depending on the bout length. They function like a spread bet on duration.
Tennis uses set totals (over/under 2.5 sets) and game totals (over/under 22.5 games is common in best-of-3 matches).
What moves a total
Totals move on news that changes expected scoring:
- Star injuries (especially offensive players in NBA/NFL).
- Pitching changes in MLB.
- Goalie changes in NHL.
- Weather (wind, rain, cold) in NFL and MLB.
- Pace adjustments (e.g., a team known for slow tempo facing a fast one).
- Sharp money on either side, especially the under (which is historically the sharper side because public action skews to overs).
Why over/under prices vary by book
Books model totals independently, and the same game often has a half-point gap between the lowest and highest totals across major books. That half-point can be the difference between a winning ticket and a push. Combined with price differences (-105 vs -115), the practical EV gap on totals is often as large or larger than on spreads.
The most common form of the gap: Book A has Over 218.5 (-110), Book B has Over 218 (-110). If the game lands at 218 exactly, Book A's over is a loser, Book B's over is a push. Same outcome, two different results. Across many bets, those refunds compound.
Common totals mistakes
- Betting the over because the teams are good offensively. Totals already price in offensive quality. The question is whether the line is set correctly given the matchup.
- Ignoring pace. Two high-scoring NBA teams can produce a low-scoring game if both play slow.
- Betting NBA totals heavy in the first quarter. Variance is high; what matters is the full-game number.
- Forgetting overtime/extra innings count toward the total. Yes, in every sport, overtime points count.
Line shopping totals
Compare both the number and the price across books. MatchupOdds shows totals on every game page with the best price highlighted. The market toggle on every sport landing page lets you switch between moneyline, spread, and total to compare quickly.
Across a full season, line shopping totals captures more value than line shopping any other market type, because totals have more pricing variance across books than spreads or moneylines on the same game.
Frequently Asked Questions
What is an over/under bet?
You bet on whether the combined score of both teams will be above (over) or below (under) a number set by the sportsbook. The score depends on both teams; you do not need to pick a winner.
What does "totals" mean?
"Totals" and "over/under" mean the same thing. Books label the market totals; the bet types within it are over and under.
What if the score lands exactly on the number?
A push: the bet is refunded. Half-point totals (e.g., 218.5) eliminate push risk; whole-number totals (218) introduce it.
Do all sports have totals?
Most major sports do, including NFL, NBA, NHL, MLB, soccer, and college basketball/football. Combat sports use round totals instead. Tennis uses set/game totals.
