US Moneyline Odds (Also known as American)

  • Used by most US bookmakers.
  • Based on a straight single bet (on a single outcome, without a points spread)
  • If the moneyline is positive, the amount quoted is the amount you would win on a $100 bet.
  • If it is negative, the amount quoted is what you would need to bet to win $100.

Fractional Odds (Also known as Traditional or British)

- Odds in fractional format (expresses the fraction of a dollar that would be wion from a $1 bet)

  • Used mainly in the UK and in international horse racing. Becoming less popular online.
  • Tell you the amount of profit relative to your stake if you win.
  • For example, if you bet £10 at odds of 3/1, you receive £30 profit if you win, plus your stake of £10 back.

Decimal Odds (Also known as European)

- Odds in decimal format (expresses the amount that would be returned from a $1 bet inclusive of original stake)

  • Common around the world but especially in Europe. Standard on betting exchanges such as BetMaker.
  • Convey the total amount you will receive if you win, including the return of your stake.
  • For example, if you bet £10 at odds of 3.75, you will receive £37.50 in total if you win.

Superstitious players sometimes avoid odds like 1.3 because they "contain" the number 13!
