Alternate Lines Calculator
Calculate fair odds for alternate spreads and totals. Compare book prices to fair value when buying or selling points on NFL, NBA, and other sports.
How Alternate Lines Work
Alternate lines let you buy or sell points from the standard spread. Buying points (moving the spread in your favor) costs you juice - you get worse odds. Selling points (taking a worse spread) gives you better odds.
Value hunting: Compare book prices to the calculated fair odds. If a book offers -150 on a line that should be -170, you've found value. This often happens during line movement or on less popular alt lines.
Teaser legs: This calculator helps evaluate whether buying 6-7 points in a teaser is fairly priced compared to standard alt line pricing.
