Closing Line Value (CLV) Calculator
For readers comparing a recorded bet price with a recorded closing price. Both prices must refer to the same selection and settlement terms.
Examples are hypothetical. CU = currency units. Use one consistent currency wherever CU appears. No live prices or provider data are fetched.
How to read the result
Positive odds-ratio CLV means the taken decimal odds were higher than the closing odds you entered. It does not prove positive expected value, remove margin, establish a fair closing price or predict the bet result.
Formula
- Price-based CLV = (taken odds / closing odds − 1) × 100.
- Taken implied probability = 100 / taken odds; closing implied probability = 100 / closing odds.
- Implied-probability change = closing implied probability − taken implied probability, in percentage points. No margin adjustment is performed.
Worked example
(2.20/2.00−1)×100 = +10.00% CLV; implied probabilities = 45.4545% and 50.00%; change = +4.5455 percentage points.
