Quick answer

This tool converts common sportsbook price formats and shows the implied break-even probability for a single offered price.

Convert odds

Enter a price and convert.

Decimal to probability

Implied probability = 1 ÷ decimal odds.

American odds

Positive American odds show profit on a $100 stake; negative odds show stake required to win $100.

Margin caveat

A single implied probability does not remove sportsbook margin. To analyze a market, compare all mutually exclusive outcomes.

Responsible gambling: Gambling involves financial risk. Never chase losses or gamble with money needed for essentials. Eligibility and legal age vary by jurisdiction.
