American Odds Explained
American odds employ positive and negative numbers to represent underdogs and favorites in that order. Positive odds reveal how much money you’d make on a $100 bet, while negative odds reveal how much you have to stake to win $100.
For example, odds of +250 mean a $100 wager returns $250 in winnings plus your initial stake. Conversely, odds of -150 need a $150 wager to earn $100. This format makes it immediately clear which team is preferred in any matchup.
Decimal Betting Odds Explained
Decimal odds display the complete payout for every dollar staked, including your original stake. A decimal odd of 3.50 means that for every $1 bet, you receive $3.50 back if you are successful, resulting in $2.50 profit plus your $1 stake returned.

Fractional Betting Odds Breakdown
Fractional odds display the ratio of profit to stake, expressed as numerator over denominator. Odds of 5/2 mean you gain $5 for every $2 bet. This traditional format has been used in sports betting and horse racing for centuries.
To determine your overall profit with fractional odds, divide the first number by the second, multiply by your stake for profit, then add your initial stake. Odds like 1/4 indicate a heavy favorite, while 10/1 denotes a significant underdog.

| American (Negative) | -150 | $166.67 dollars ($66.67 winnings + $100 dollars stake) | 60.00% |
| Decimal | 3.50 | $350 dollars (contains stake) | 28.57% |
| Fractional Odds | 5/2 | $350 dollars ($250 dollars earnings + $100 stake) | 28.57% |
