What is totals betting?
Totals betting is the American term for wagering on whether the combined score of both teams in a game will finish over or under a number posted by the sportsbook.
Every US game comes with three headline bets: the moneyline, the spread and the total. The total is the sportsbook’s estimate of the combined points. You bet over or under it. Who wins is irrelevant.
It’s the same market that the UK and Europe call over/under. The vocabulary differs a little: Americans say “the total is 221.5” or “I’m on the over”, and you’ll see it written as O/U 221.5. Both sides are typically priced near −110.
Example
An NBA game has a total of 221.5. You bet $110 on the over at −110.
| Final score | Combined | Over 221.5 | Under 221.5 |
|---|---|---|---|
| 115–109 | 224 | Wins | Loses |
| 108–104 | 212 | Loses | Wins |
At 115–109 you get $210 back, a $100 profit.
Typical totals give you a feel for each sport. NBA games sit in the 200s, NFL games usually in the high 30s to low 50s, baseball around 7 to 10 runs, hockey around 5.5 to 6.5 goals.
Where you’ll see it
- Game totals, as above.
- Team totals: one team’s points only.
- Half, quarter and period totals.
- Player totals, which are really prop bets: points, yards, strikeouts.
Watch out
- Overtime usually counts in US sports totals. A game tied at 100–100 heading to overtime is great news for over bettors and awful for the under. Football (soccer) totals are the exception: 90 minutes plus stoppage time only.
- Whole-number totals can push. A total of 45 and a 24–21 final means everyone gets refunded.
- Weather and pace matter more than team quality. Wind and rain pull NFL totals down. Two fast-paced NBA teams push them up. The line already includes all of that, so you need to know something the number doesn’t.
- The public loves overs. Books know, and shade accordingly.
