Convert sports betting odds

There are three main types of sports betting odds used by major sportsbooks from around the world, moneyline, decimal and fractional.

Moneyline Odds (American style)

  • The moneyline is used as a standard by most US sportsbooks.
  • Odds based on a straight single outcome (without a points spread).

Example: When positive (e.g +200), this means you will get $200 back as profit from a $100 bet.

When negative (e.g -200), you need to bet $200 to win $100 profit.

Decimal Odds (European style)

  • Decimal odds are the most popular style used by sportsbooks and exchanges around the world, especially in Europe.
  • Decimal odds show the total amount you can win, which includes your initial stake.

Example: If you bet $10 at odds of 2.5 and win you will receive $25 back in total.

Fractional Odds (British or traditional style)

  • Fractional odds are found mostly when betting with UK & Irish bookies.
  • The odds show the amount of potential profit in relation to your stake.

Example: If you bet $10 at odds of 2/1 and win you will receive $20 profit, plus your original $10 stake back.
