Enter the odds you took and the closing line. The calculator returns your CLV in cents, the implied-probability delta, and a verdict on whether you beat the close.
For every bet you place, record two prices: the odds at the moment you bet (your taken price) and the final closing line at the same sportsbook. The gap between them is your closing line value. Positive CLV means the market moved toward your side after you bet — the strongest available signal of long-run betting edge.
Reading the result: CLV in cents tells you how many price points you beat the closing market by. The implied-probability delta converts that to a probability-points gain — the more directly comparable number across different price ranges. A CLV of +15 cents on a +135 bet that closed at +120 means the market eventually agreed your bet was worth about 1.5-2 implied probability points more than the price you paid.
