How to Use the Betting Odds Calculator
This betting odds calculator allows you to convert odds between three major formats used by bookmakers worldwide. Understanding odds in different formats helps you compare betting opportunities across multiple sportsbooks and find the best value.
Decimal Odds
Decimal odds (European format) show your total return for every $1 wagered, including your stake. For example, odds of 2.50 mean you'll receive $2.50 for every $1 bet, including your original stake.
Fractional Odds
Fractional odds (UK format) show your profit relative to your stake. Odds of 3/2 mean you'll win $3 for every $2 wagered, plus your stake returned.
American Odds
American odds use positive and negative numbers. Positive odds (+150) show how much profit you make on a $100 bet. Negative odds (-200) show how much you need to bet to win $100.
