Point Spread Calculator: Master Against the Spread Betting

Point spread betting levels the playing field between favorites and underdogs. Our calculator shows payouts, break-even rates, and helps you understand when buying points makes mathematical sense.

What Is a Point Spread?

A point spread is a handicap applied to a favorite to create a more even betting market. Favorites must win by more than the spread; underdogs can lose by less than the spread and still "cover."

Quick Answer: Point spreads use a standard -110 vig (bet $110 to win $100). The favorite must win by more than the spread to cover; the underdog covers if they win outright or lose by less than the spread. A "push" (exact spread margin) returns your bet. Break-even win rate at -110 is 52.38%.

Understanding Point Spreads

Reading the Spread

Team Spread Meaning
Chiefs -7.5 Must win by 8+
Raiders +7.5 Can lose by 7 or less
Lakers -3 Must win by 4+
Celtics +3 Can lose by 2 or less

Cover vs Not Cover

Chiefs -7.5 vs Raiders:

Final Score Spread Result
Chiefs 28, Raiders 14 Chiefs cover (-7.5)
Chiefs 24, Raiders 20 Raiders cover (+7.5)
Chiefs 21, Raiders 14 Chiefs -7.5 loses (won by 7, needed 8)

Push Scenarios

With whole-number spreads, exact margins push:

Lakers -3:

  • Lakers win by 4+: Lakers cover
  • Lakers win by 1-2: Celtics +3 covers
  • Lakers win by exactly 3: PUSH (bets returned)

Half-point spreads eliminate pushes.

Standard Spread Betting Odds

Typical -110 Both Sides

Side Odds Break-Even
Favorite -110 52.38%
Underdog -110 52.38%

Why -110?

The difference from -100 (even money) is the vig:

  • True 50/50 should pay +100
  • -110 means you risk $110 to win $100
  • Vig is ~4.54% per side

Adjusted Lines

When action is lopsided, books adjust odds:

Scenario Favorite Underdog
Balanced -110 -110
Favorite heavy -115 -105
Underdog heavy -105 -115

Point Spread Calculations

Payout Formula

Profit = Bet × (100 / |Odds|)  [for negative odds]
Profit = Bet × (Odds / 100)    [for positive odds]

Examples

$100 at -110: Profit = $100 × (100/110) = $90.91 Total return = $190.91

$100 at -105: Profit = $100 × (100/105) = $95.24 Total return = $195.24

Break-Even Win Rate

Break-Even % = |Odds| / (|Odds| + 100)
Odds Break-Even
-110 52.38%
-115 53.49%
-120 54.55%
-105 51.22%

Buying Points

What Is Buying Points?

Paying extra vig to move the spread in your favor:

Original Buy 0.5 New Cost
-7 at -110 -6.5 -120
+3 at -110 +3.5 -120

When Buying Points Makes Sense

Key Numbers in Football:

  • 3 (field goal margin)
  • 7 (TD margin)
  • 10, 14 (multiple scores)
Moving Off/Onto Value
Off 3 (e.g., -3 to -2.5) High
Onto 3 (e.g., -3.5 to -3) High
Off 7 (e.g., -7 to -6.5) High
Onto 7 (e.g., -7.5 to -7) High
Random numbers Low

Buying Point Math

Original Cost to Buy New Line Worth It?
-3 at -110 -120 -2.5 Often yes
-5 at -110 -120 -4.5 Usually no
-7 at -110 -120 -6.5 Often yes

Only buy off/onto key numbers.

Finding Value in Spreads

Line Shopping

Different sportsbooks offer different lines:

Book Spread Odds
Book A -7 -110
Book B -7 -105
Book C -6.5 -115

Best value depends on your analysis.

Line Movement

Movement Possible Reason
-3 to -3.5 Money on favorite
-3 to -2.5 Money on underdog
-3 to -3 (-115) Vig adjustment

Common Spread Betting Mistakes

1. Ignoring the Vig

Mistake: "It's basically 50/50" Reality: -110 requires 52.38% to break even Fix: Account for vig in all analysis

2. Overvaluing Favorites

Mistake: "Chiefs will crush them" Reality: Spread already accounts for strength difference Fix: Evaluate if spread is accurate, not just who wins

3. Buying Non-Key Numbers

Mistake: Buying from -5 to -4.5 Reality: Non-key numbers don't land often enough Fix: Only buy off/onto 3 and 7 in football

4. Chasing Steam

Mistake: Following line movement blindly Reality: By the time you see it, value may be gone Fix: Have independent analysis before seeing lines

Frequently Asked Questions

What does ATS mean?

Against the spread. A team's ATS record shows how often they cover the spread, not just win.

Why do spreads have half-points?

To eliminate pushes. -7.5 means one side definitively wins the bet.

Is spread betting better than moneyline?

Depends. Spreads offer ~-110 both sides; moneylines vary. For heavy favorites, spreads often have better value.

How are spreads set?

Oddsmakers estimate point differentials, then adjust based on betting action to balance their book.

What happens if a game ends exactly on the spread?

With whole-number spreads, it's a push—bets are returned. Half-point spreads prevent this.

Should I always take the points?

Not always. Evaluate if the underdog can cover, not just whether points seem "free."

Pro Tips

  • Shop lines: 0.5 points matters over time

  • Know key numbers: 3 and 7 in football are critical

  • Track ATS records: Not just win/loss records

  • Consider totals: High-scoring games have different spread dynamics

  • Manage bankroll: -110 vig adds up over hundreds of bets
