Odds movement
calculator

See the change between two prices and the probability each one implies. The values you type are not sent to a server.

Short answer

Odds movement is the percentage change between two observations: (latest price − first price) / first price × 100. For example, a move from 2.10 to 1.85 is about −11.90%. The calculator also shows the change in implied probability; a price change alone is not evidence of a cause or a result.

Compare two prices

LOCAL CALCULATION

Enter decimal odds greater than 1.00. A dot or a comma both work.

RESULT

Opening probability—
Latest probability—

Enter two odds to see the results.

How is it calculated?

Implied probability = 100 / odds.
Change in odds = (latest − opening) / opening × 100.

How to read it

For example, a move from 2.10 to 1.85 is about −11.90%. Implied probability includes the market margin, and a price change on its own is not evidence of a cause or of the result.
