American odds, also known as moneyline odds, employ positive and negative figures to indicate underdogs and favorites, with the figures showing how much you need to wager or how much you can win based on a $100 stake.
For example, odds of -150 mean you must wager $150 to win $100, while +200 odds indicate a $100 bet would return $200 in profit, making this format particularly popular across North American betting markets.
Decimal odds display the total return you’ll obtain for every dollar wagered, including your initial wager, making calculations straightforward by simply multiplying your stake by the decimal number shown.
A decimal odd of 2.50 means a $100 stake yields $250 total ($150 profit plus your $100 stake), which is why this structure dominates European, Australian, and Canadian sportsbooks for its simplicity and clarity.
Fractional odds show the ratio of profit to stake using fractions, with the numerator showing possible winnings and the denominator specifying the amount you need to wager to achieve that return on your investment.
Odds of 5/2 show you’ll make $5 for every $2 staked, so a $100 wager would deliver $250 profit plus your starting bet, so this conventional format remains still prevalent in UK and Irish wagering sectors today.
