How It Works

Enter each leg's spread and odds as the book prices the straight bet. The calculator backs out the true line, then computes the cover probability and fair odds at the teased spread. The combined probability across all legs determines the fair teaser price — compare it to what the book is actually offering to see if there's an edge.

Key numbers (3, 7, 10, 14) are scoring margins that occur disproportionately often in football. Legs that cross these numbers gain more cover probability per teaser point than legs that don't.
