Odds Conversion Calculators

There are three major formats in which most online sportsbooks quote odds:

It can be confusing to calculate your odds but by using the odds calculators on this page you'll be able to convert sports betting odds across the three different formats, or convert chance of winning percentages to each of the different formats, hassle-free and in a flash.

Odds Converter Calculator

Use this odds & profit calculator to convert known odds in one format to your preferred odds format.

To use, simply input your known odds in either Moneyline (American), Fractional (UK) or Decimal (European) odds into one of the boxes and click the convert button. The odds equivalent in all other formats will then be shown, as well as your expected profit. Remember that you would also have your original bet returned to you, so add that value to the profit for your total payout figure.
