Frequently Asked Questions (FAQs)

What is closing line value?

Closing line value (CLV) is a measure of the value of a bet at the time it is placed compared to the closing odds. You can calculate it by comparing the odds you received when you placed your bet to the final odds when the event starts. If the odds you received were better than the closing odds, then the bet has positive CLV. If the odds you received were worse than the closing odds, then the bet has negative CLV. Find out more about closing line value as a betting strategy.

How is closing line value calculated?
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 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 closing line value 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.
Should I 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 baseball?
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 hockey?
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.
Can I compare two moneylines in NFL, CFB, NBA, or CBB?
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 calculate 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.
