Implied probability calculator
Decimal odds hide a probability. Type any price to see the chance it implies.
Implied probability50.00%
How it works
The implied probability is 1 divided by the decimal odds. Odds of 2.00 imply 50 percent, odds of 4.00 imply 25 percent. The bookmaker margin is still inside this number, so the implied chances of all outcomes add up to more than 100 percent.
