Implied Probability Calculator
Convert odds into the implied win probability — and turn a probability back into fair odds.

Probability → Fair Odds
Implied probability is the win rate the odds assume. If your own estimate of a team's chance is higher than the implied probability, the bet may hold value. Bookmaker margin (the overround) means implied probabilities across all outcomes add up to more than 100%.
Frequently asked questions
Divide 1 by the decimal odds and multiply by 100. For example, decimal odds of 4.00 give an implied probability of 25% (1 ÷ 4.00 = 0.25).
