BTB Analytics Tools

Turn your projection into a measurable edge.

Compare your projected spread with the current market and price to estimate cover probability, implied probability, and the size of the edge. Start with NFL or college football below, then use the college basketball calculator farther down the page.

Step 01
Enter the market number

Use the spread and American odds currently available. CFB also requires the game total.

Step 02
Enter your projection

Use the spread you believe is the true fair line. Enter spreads in half-point increments.

Step 03
Read the edge

Positive edge means your estimated cover probability is higher than the probability implied by the price.

NFL

NFL Spread Edge Calculator

Compare a market spread to your true line and translate the difference into a cover probability and edge.

ⓘRange: Current and true lines must be between -19 and +19.
College Football

CFB Spread Edge Calculator

CFB incorporates the game total so the calculation can account for different scoring environments.

ⓘWhy total matters: 0-50, 50.5-59.5, and 60+ are evaluated as separate scoring environments.
College Basketball

College Basketball Edge Calculator

Enter the market spread, your projected spread, and the available American odds to estimate cover probability and edge.

ⓘExample: If the market is -4.5 and your projection is -6.0, enter each number from the same team's perspective.
How to interpret the result: Cover Probability is the calculator's estimated chance of covering the entered market spread. Implied Probability converts the entered American odds into the market's break-even percentage. Edge is the difference between those two percentages.
