Understanding Betting Odds

Introduction to Betting Odds

Betting odds represent the probability of an outcome and determine your potential payout. Understanding odds is fundamental to sports betting.

American Odds (Moneyline)

American odds use positive and negative numbers:

• Positive odds (+150): Shows profit on a $100 bet. +150 means win $150 on $100.
• Negative odds (-150): Shows amount needed to win $100. -150 means bet $150 to win $100.

Decimal Odds

Decimal odds show total return (stake + profit). Odds of 2.50 mean $2.50 returned for every $1 wagered.

Fractional Odds

Common in UK. 3/1 (three-to-one) means win $3 for every $1 bet.
