American odds use a baseline of $100. Positive odds (+150) tell you how much profit you win on a $100 bet. Negative odds (-200) tell you how much you need to bet to win $100 profit. They are the standard format used by U.S. sportsbooks.
Decimal odds represent the total payout per $1 wagered, including your original stake. Decimal 2.50 means a $1 bet returns $2.50 total ($1.50 profit + $1 stake). This format is popular in Europe, Australia, and Canada because it makes calculating payouts straightforward.
Fractional odds (like 3/2) show profit relative to stake. A 3/2 fraction means you win $3 for every $2 you bet. This is the traditional format in the UK and Ireland. The number on the left is profit, the number on the right is stake.
Implied probability converts odds into a percentage showing how likely the sportsbook thinks an outcome is. It tells you the break-even win rate at those odds. If the implied probability is 40%, you need to win more than 40% of the time at those odds to be profitable.
