What this tool calculates
Measure closing line value by comparing the decimal odds you took with the market’s closing odds, using both price ratio and implied probability.
Price CLV = (your decimal odds / closing decimal odds − 1) × 100%. A positive value means you captured a higher payout than the closing market offered.
Treat the result as a decision aid. Verify inputs, market rules, and settlement conditions before placing a bet.
Worked example
Taking 2.10 when the market closes at 2.00 gives +5% price CLV. Your price implies 47.62%, while the close implies 50%.
| Example | Interpretation |

Tips and limitations
- Use current prices and realistic assumptions.
- Compare several scenarios instead of relying on one point estimate.
- Rounding can create small differences from sportsbook displays.
