CLV calculator: did you beat the closing line?
Enter the odds you took and the closing odds for the same bet. You get your CLV and what your bet was worth according to the final market price.
How it is calculated
CLV = (your odds ÷ closing odds) − 1. With 2.10 and a close of 1.95 that is +7.7%.
Expected value uses the closing probability: your odds × (1 ÷ closing odds) − 1. If you know the closing margin, enter it and the probability is taken without it (or work it out with the fair odds calculator).
Why it matters
A single result is too noisy to judge a bet. Beating the close repeatedly is the best sign your prices are good. We explain it with examples in what CLV is, and our record is public at matchscan.co/api/clv.json.
Frequently asked questions
What is a good CLV? A positive average held over hundreds of bets. Above +2% on average is hard to sustain.
Which closing odds should I use? Those of the most efficient market you have, right before kick-off. The lower the margin, the better the benchmark.
Does a positive CLV guarantee a profit? No. It improves your numbers on average, but any single bet can lose.
