How to Use This Calculator

Enter decimal odds you bet live (open) and decimal odds at the closing line you care about (often the final pre-game close or an end-of-match number). The tool outputs CLV % like the standalone CLV calculator.

Same bet

Open and close must reference the same market selection.

Live vs pregame close

Define what “close” means for in-play analysis—some bettors compare to pre-game close, others to final minute price.

Decimal odds

Both fields require decimal prices > 1.

Speed

Live markets move fast—timestamp screenshots when you track CLV seriously.

In-Play CLV

Closing line value still applies in live betting: did you beat the price the market settled on at your chosen reference time?

Examples

Example 1 — Same as CLV defaults

Open 2.05, close 1.95 → negative CLV versus that close—practice reading the widget.

Example 2 — Halftime line

Compare your halftime grab to the odds available at full time if that is your benchmark.

Example 3 — Limit orders

Exchanges let you peg prices—CLV still measures quality vs reference close.
