Sports: NFL Spread

Introduction

To use this calculator, enter both the fair point spread and the alternate point spread. Generally, the alternate point spread must be within seven points of the fair point spread. However, if the line movement touches a line of 0, you can go to a maximum difference of 7.5, and if it crosses 0, you can go to a difference of 8 points. For example, if the fair spread is -3, you can enter alternate spreads from -10 to +5.
