Point Spread Definition, Examples

The perceived stronger team (the favorite) must win by a certain number of points/runs/goals to cash your bet. The worse team (the underdog) can lose by fewer than that same amount of points, or just win the game.
Let's use a 2023 NFL Week 1 game as an example.
- 49ers win by 4+ points: 49ers bettors win
- 49ers win by 1-2 points: Steelers bettors win
- Steelers win the game: Steelers bettors win
- 49ers win by exactly 3: It's a push, and bets are refunded
There's also an associated cost with betting each spread, listed next to the margin of victory. So if you're betting the 49ers at -3 (-110), you must risk $1.1 for every $1 you want to win. We'll get into more detail below.
Sportsbooks apply the spread concept to way more than just the final score. Things like France -2.5 corner kicks vs. Germany, or Chiefs total touchdowns -1.5 vs. the Cowboys are also spreads.
Here's how point spreads work.
Point Spreads, Explained
Point Spread Definition
A point spread is a bet on the margin of victory in a game.
The stronger team or player will be favored by a certain number of points, depending on the perceived gap in ability between the two teams.
A minus sign (-) means that team is the favorite.
A plus sign (+) means that team is the underdog.

NFL Point Spread Examples, How it Works
It's easiest to understand point spreads by seeing them.
Let's take the 2022 Super Bowl example:
- Rams -4.5 (must win by 5+)
- Bengals +4.5 (can win or lose by 1-4 points)
Score: Let's say the Rams win 27-24 — Bengals spread bettors would win their bets. If the Rams win 30-20, Rams spread bettors would cash.
From Week 11 of the 2021 NFL season:
- Bills -13.5 (must win by 14+)
- Jets +13.5 (can lose by 1-13 or win)
Score: BUF 45, NYJ 17 (Bills cover -13.5, because they won by 28)
Let's take another example Week 11:
- Rams -3.5 (need to win by 4 or more)
- 49ers +3.5 (need to lose by 3 or fewer, or win)
Score: SF 31, LAR 10 (49ers cover +3.5, because they won the game outright)

What Does -110 Mean Next to the Spread?
That means for every $1 you want to win, you have to risk $1.10. So if you want to win $20 on a bet, you'll have to risk $22.
If you bet $22 on the Bills -13.5 and Buffalo wins by 14 points, you'll win $20. If they only win by 10, you lose $22.
Point spreads have an even tax on both sides because we expect each team to cover the point spread about 50% of the time.
When betting moneylines — which requires you to pick the winner straight-up — you can get bigger payouts because the likelihood of the worse team winning the game outright is much lower than it just covering the spread.

How Are Point Spreads Calculated & Made?
We could write another 5,000 words about how point spreads are truly made, but in the simplest terms, it's a 3-step process.
- Oddsmakers build mathematically-driven ratings for each team before the season and continue to tweak them as games are played.
- They use those ratings, plus factors like home-field advantage, rest, and injuries, to create a point spread in advance of a scheduled game.
- Bettors then begin wagering on that initial point spread, which will influence the spread and move it to the most accurate possible number.
- Most sportsbooks do not create their own lines, and simply copy the movement they see at market-making books.
What Does Covering the Spread Mean?
"Covering the spread" is another way to say that a team won a point spread bet. In the above example, the Bills or more as a -13.5 favorite means they covered the spread.
If the Jets (+13.5) lost by 13 points or fewer, or won the game, they covered the spread.
What does it mean when a team is 9-2 ATS this season? ATS stands for "against the spread." So an ATS record is simply wins and losses against the spread.

The odds are just changed depending on the ability of the team — you won't get -110 on both sides.
