Point Spread to Moneyline Converter
A point spread and a moneyline are two ways to express the same game. This converter takes a spread and its juice, then uses sport-specific scoring distributions to show the implied moneyline equivalent — useful for pricing teasers, alternates, and same-game parlay legs.
The moneyline equivalent is what a straight moneyline bet would need to be priced at to match the spread's implied win probability. Use it to spot mispriced alternates.
Price buying a half-point →Each sport uses a different scoring distribution (σ)
Negative = favorite (e.g. -3 means covering team must win by more than 3)
How this works
Formula
Convert price to implied prob, then map prob to spread using sport-specific σ (NFL ≈ 13.86 pts).
Worked example
NFL -3 -110 → implied prob ≈ 58% → moneyline equivalent ≈ -138.
FAQ
Why convert spread to moneyline?
Teaser and SGP pricing depends on the moneyline-equivalent of the spread. The conversion exposes whether the book mispriced an alternate.
What's the σ (standard deviation) for each sport?
NFL ≈ 13.86, NBA ≈ 12, NHL ≈ 2.5, MLB ≈ 4. We use these to map spread → win probability.
How much is a half-point worth?
Depends on the key number. Crossing 3 in the NFL is worth ~25 cents of price; crossing 7 is worth ~15 cents. See the Half-Point Calculator.
Does this work for college football?
Yes — same σ as NFL works reasonably for FBS games. Smaller-spread games can vary.
Can I use this for buying points?
Yes — use it together with the Half-Point Calculator to price exactly what each half-point should cost.
