To calculate potential winnings from a bet, you need to understand the odds format used by your sportsbook. For example, if using American odds, a positive number (e.g., +150) indicates the amount youd win on a $100 bet, while a negative number (e.g., -170) shows how much you need to bet to win $100. Multiply your stake by the odds (converted to decimal form) to find your potential winnings.
