American odds show how much profit you make on a $100 stake at positive odds, or how much you need to stake to win $100 at negative odds.

Decimal odds show your total return for every $1 staked, including your original stake.

Fractional odds show profit compared with stake. For example, 3/2 means you win $3 profit for every $2 staked.

Implied probability is the breakeven win rate suggested by the odds before removing any sportsbook margin.
