Closing-Line Value (CLV) Calculator — Did You Beat the Close?
Compare the odds you took to the closing price to measure your edge.
Closing-line value is the gap between the odds you took and the final, closing odds just before the off. Consistently beating the close is the single most reliable sign that you’re finding genuine value — over time it predicts profit better than a handful of results.
Enter the price you got and the closing or starting price, and the calculator returns your CLV percentage and whether you beat the line.
How it works
If you took $4.00 and the horse closed at $3.50, you beat the market — your price implied a bigger chance than the final, sharper market did. Positive CLV over many bets is what separates skill from luck.
It won’t tell you about any single bet (you can beat the close and still lose) — it’s a long-run quality signal across your whole record.
CLV % = ( odds taken − closing odds ) ÷ closing odds × 100
Worked example
- CLV: +5.0%
- Verdict: you beat the close
- Read across many bets, consistent positive CLV indicates a real edge
FAQ
- What is closing-line value?
- The percentage difference between the odds you took and the closing odds. Positive means you beat the market’s final price.
- Why does CLV matter?
- Because the closing line is the market’s sharpest estimate. Beating it consistently is the best available evidence that your selections have an edge.
- Can I have good CLV and still lose?
- Yes, over a small sample — variance is large. CLV is a long-run signal; track it across hundreds of bets in the Bet Tracker.
This scores one bet against the close. The Bet Tracker measures your closing-line value across every bet — the number professionals judge themselves on.
