What is a Teaser Calculator?

Bettor Ed's NFL Teaser Calculator is a free sports betting tool that shows the expected win probability and expected value (EV) for NFL teasers. You select points to tease, the odds your sportsbook gives, and point spreads to tease. The calculator outputs the probability each leg covers and whether your teaser has positive expected value.

How do you calculate teaser odds?

This calculator uses historical NFL game data and the current market consensus line to find the probability that each teased spread will cover. For each leg, the calculator finds similar historical games (matching the spread and total) and looks at what actually happened — how often did teams in similar situations cover the teased number? The fair probability for the teaser is the product of all leg probabilities. Finally, that probability is compared against your sportsbook's odds to determine the expected value.

What are consensus lines?

Consensus lines are the "true" market odds derived by averaging lines from the sharpest sportsbooks. Using consensus lines helps remove the bias of any single book and gives you the most accurate starting point for calculating teaser probabilities. The calculator automatically fetches live consensus lines so you don't have to enter them manually.

Do totals matter for teasers?

Yes — totals influence how games play out. Higher totals generally indicate more possessions and scoring opportunities, which can affect margin distributions. The calculator factors in the game total when finding similar historical matchups, giving you a more accurate probability estimate tailored to each game's expected pace and scoring environment.

Are these teaser numbers accurate?

The results are based on thousands of actual NFL games, providing a strong empirical foundation for teaser pricing. However, the results can still be noisy, especially at larger point spreads (roughly 11 and up). Treat the outputs as a powerful guide to teaser value rather than a guarantee of exact outcomes.
