If an NFL spread is -6.5 at -110, what's the fair price to lay -7 instead? If an NBA total is at 207, what's the right price to take it up to 210 or down to 204?

The ability to move between numbers and find fair prices is a fundamental question in sports betting and our Alternate Lines Calculator gives you a tool rooted in our data science to do it quickly and easily in order to find inefficient prices deep in the menus, anywhere the sportsbooks may be hiding them.

Calculate the Price on Alt Sides and Totals

Sportsbooks can be prone to making errors in pricing alternate lines.

With our Alt Lines Calculator, you can zero in on these mistakes and find plus-EV spots beyond mainline sides and totals.

Distribution and pricing of our alt lines are backed by rigorous data science, updated regularly for each sport as scoring environments and rules change.

Account for Every Factor

When calculating alternate totals, account for the impact of the spread. When calculating alternate spreads, account for the impact of the total.

We make it easy to input every variable that impacts an alt line calculation.

See fair price outputs as a vig-free number, or with vig included so you're always comparing apples to apples.

When and how to use it

Common questions we receive and strategies for using this calculator

Is vigorish (house edge) factored into this?

Vig is not factored unless you want it to be. You can enter both sides of the vig for a side or both sides of the total price to get a more accurate answer. You can also remove the vig from these lines via the Remove Vig button.

Can I use the Alternate Lines Calculator for leagues not listed?

No, the Alternate Lines Calculator is specifically designed for just the leagues listed.

Does the total matter when seeking the alternate line price?

Yes, it does. The impact varies by league. You can enter the total when using a spread via the "Show More Info" link. It is assumed the total will be the same for both the primary line as well as the alternate line.

How are these numbers derived?

The value of each half-point in a spread or total depends greatly on the origination point and the distribution based on that point of origin. We take historical data to create a correlation and then price it over each half-point the alternate line moves through.

Are these numbers correct?

To the best of our knowledge, these numbers are correct. However, we do review and adjust these numbers after each season of each league. This is because gameplay evolves in these leagues, which affects the known distributions.
