Buying Points
Paying worse odds to shift a spread or total in your favor, commonly to clear key football numbers like 3 and 7.
Buying points is an option at many sportsbooks that lets bettors shift the spread or total on a wager in exchange for worse odds. Each half-point move usually costs about 10 cents of added juice. Moving a spread from -7 to -6.5, for instance, might shift the odds from -110 to -120, forcing the bettor to risk more for the same return. The logic is simple: you pay a premium to improve your number, lowering the chance the original spread or total lands against you by a thin margin.
Buying points comes up most in football betting, where final margins bunch around certain key numbers. Because touchdowns are worth 7 points and field goals 3, a disproportionate share of NFL games end by exactly 3 or 7. Shifting a spread off or through these numbers can meaningfully raise the odds of a win or push. Buying through non-key numbers (say, -5 to -4.5), by contrast, brings far less statistical payoff, and the cost in worse odds often exceeds the slim gain in win probability.
Example
A sportsbook lists Team A as a 7-point favorite at standard -110 odds. You buy a half-point, moving the spread from -7 to -6.5 at -125. Now, if Team A wins by exactly 7, your bet wins rather than pushing. To win $100 here, 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-buy scenarios.
Key Points
- Key numbers matter most: In football, buying off 3 and 7 yields the largest statistical benefit since these are the most common margins of victory. Buying through other numbers rarely pays.
- Cost adds up over time: Each purchased half-point trims the potential payout. Across hundreds of bets, the cumulative cost can meaningfully erode returns if used carelessly.
- More valuable for favorites through 3: Moving a favorite from -3 to -2.5 is among the most recommended point-buys, since a substantial share of NFL games end on a 3-point margin.
- Less relevant in basketball and baseball: Margins in these sports spread more widely and do not cluster on specific numbers, so buying points offers less value.
- Compare across sportsbooks first: Before paying to buy a point, check whether another book already posts a more favorable number at standard odds.
