Understanding Betting Odds Formats

Different sportsbooks and regions use different odds formats. American odds are the standard in the US, decimal odds are common in Europe and Australia, and fractional odds are traditional in the UK.

American Odds

Positive odds (+150) show how much profit you win on a $100 bet. Negative odds (-110) show how much you need to bet to win $100 profit.

Decimal Odds

Decimal odds represent the total return per $1 wagered, including the stake. Odds of 2.50 mean a $1 bet returns $2.50 total ($1.50 profit + $1 stake).

Fractional Odds

Fractional odds (like 3/2) show profit relative to stake. A 3/2 bet pays $3 profit for every $2 wagered.
