Closing Line Value Calculator
Calculate closing line value (CLV) to measure the quality of your betting timing
About this calculator
The Closing Line Value Calculator helps sports bettors evaluate the quality of their betting timing by comparing the odds they received to the final closing odds. CLV measures whether you consistently beat the market by getting better prices than the final line. Positive CLV indicates sharp betting decisions and is strongly correlated with long-term profitability, making it an essential metric for serious bettors to track their performance.
How to use
Enter the odds you bet at and the closing odds for the same wager. The calculator will determine your CLV percentage, showing whether you beat the closing line (positive CLV) or got worse odds (negative CLV). Track multiple bets to analyze your overall line shopping effectiveness and betting timing skills.
Frequently asked questions
What is a good CLV percentage?
Consistently achieving +2% to +3% CLV is considered excellent, while any positive CLV indicates you're beating the market closing prices.
Why is CLV important for betting success?
CLV is the strongest predictor of long-term betting profitability, more reliable than short-term win rates or profit tracking alone.
Can I have negative CLV but still profit?
Yes, short-term profits are possible with negative CLV, but consistently poor timing will lead to losses over time.
