Buying Points
Paying worse odds to get a better spread or total, often to cross key football numbers like 3 and 7.
Buying points is a feature many sportsbooks offer that lets bettors shift the spread or total on a wager in exchange for worse odds. Each half-point usually costs about 10 cents of extra juice. Moving a spread from -7 to -6.5, for instance, might shift the odds from -110 to -120, so you risk more to win the same. The idea is simple: you pay a premium to improve your number, lowering the chance the original spread or total burns you by a thin margin.
Buying points comes up most in football, where final margins bunch around certain key numbers. Since touchdowns are worth 7 points and field goals 3, an outsized share of NFL games land on exactly 3 or 7. Moving a spread off or through these numbers can lift the chance a bet wins or pushes. But buying through non-key numbers (say -5 to -4.5) brings far less statistical gain, and the cost in worse odds usually outweighs the slim bump in win probability.
Example
A book lists Team A as a 7-point favorite at standard -110. You buy a half-point, shifting the spread from -7 to -6.5 at -125. Now if Team A wins by exactly 7, your bet wins instead of pushing. To win $100, you risk $125 instead of $110. Whether the trade pays off depends on how often games land on that exact number. In the NFL, roughly 9% of games are decided by exactly 7 points, making this one of the more defensible point-buys.
Key Points
- Key numbers matter most: In football, buying off 3 and 7 gives the most statistical value since these are the most common margins. Buying through other numbers rarely pays.
- Cost adds up over time: Each half-point bought trims the payout. Over hundreds of bets, the cumulative cost can erode returns badly if used loosely.
- More valuable for favorites through 3: Shifting a favorite from -3 to -2.5 is one of the most recommended point-buys, since a big share of NFL games end on a 3-point margin.
- Less relevant in basketball and baseball: Margins in these sports spread out and do not cluster on set numbers, so buying points offers less value.
- Compare across sportsbooks first: Before paying for a point, check whether another book already lists a better number at standard odds.
