Learn about the CLV Calculator

Tracking your Closing Line Value (CLV) is important. The Closing Line Value Betting Calculator at Unabated helps you do this across both spreads and totals. Enter the wager you made and then the price the line closed at and it will compute your CLV. It works with NFL, NBA, MLB, NHL, as well as College Football and College Basketball.

Frequently Asked Questions (FAQs)

How do I use this?
We have an explainer video that can be played by clicking the Teach Me link above. It should explain everything.
How do you calculate closing line value?
To calculate your closing line value, you subtract the implied probability of the line you bet from the implied probability of the closing line. Then divide that sum by your implied probability.
Can’t I just subtract the implied probability of my bet from the implied probability of the closing line?
You can, but that doesn’t give you a ratio of your bet compared to the closing line. It just gives you the difference in implied probability.
I’ve seen other sites that have a different CLV equation, are they wrong?
There’s no universally accepted CLV equation. We tend to believe our way is best however. The method of just subtracting does not give you a percentage gained in value. Just absolute gain.
Do I need to enter the closing line vig-free or how it appears at the sportsbook?
We recommend entering the vig-free closing line because this will tell you your value with the vig factored in. This is also you Expected Value (EV). If you choose to enter the price as it appears at the sportsbook, you’ll have to subtract the vig from the result because it’ll be inflated. Typically, this means subtracting 4.55% from the result.
Why do I need to enter the closing moneyline instead of the closing runline for MLB?
MLB is a moneyline sport, giving us just the runline doesn’t tell us enough information. However, with the moneyline we can better calculate the gain.
Why do I need to enter the closing moneyline instead of the closing puckline for NHL?
NHL is a moneyline sport, giving us just the puckline doesn’t tell us enough information. However, with the moneyline we can better calculate the gain.
I want to compare two moneylines in NFL, CFB, NBA, or CBB, how do I do that?
Since your query doesn’t involve moving through any spread prices (runline or puckline), you can enter 0 in the Spread field, and the moneyline prices in the Price fields.
How do I compute my EV based on the CLV result?
The nice part about our CLV calculator is that if you took the vig-free closing line, this is also your EV.
