Odds Calculator

Like a personal preference for internet browsers, most bettors have their favourite odds format, which is why we have created a handy Odds Converter Calculator. These preferences tend to follow cultural lines. Fractional odds dominate in the UK with their roots in betting on horse racing, but they are limited to familiar fractions which became problematic as betting has evolved and moved online.

Decimal odds provide a purer translation of odds with greater range – Pinnacle quote to three decimal places and have grown in popularity as betting has moved online. They also lend themselves to digital feeds such as APIs which are how information is shared across the internet.

Americans came up with their own way of measuring betting risk – American odds – based either on the return of $100 (when implied probability is less than 50%) denoted with a +, whereas when implied probability is greater than 50% the odds are expressed in terms of what you have to bet to win $100 .

While it is valuable to understand what betting odds represent and convert between American odds, Decimal odds and Fractional odds in your head, our Odds Converter Calculator conveniently does it all for you.

Convert seamlessly between American, Decimal and Fractional odds and start learning the shortcuts for yourself.
