Positive numbers show how much earnings you’d make on a $100 wager, while negative numbers indicate how much you need to wager to win $100.

Underdogs display plus odds, providing higher potential profits to compensate for the increased risk. This clear distinction helps bettors quickly assess the implied probability and potential value of each wagering option.
