What is a Bet Calculator?
A bet calculator is a free tool that helps you quickly determine your potential winnings from a bet before you place it. Whether you're betting on sports, horse racing, or any other event, our calculator makes it easy to see exactly how much you could win based on your stake and the odds offered.
Our free bet calculator supports all major odds formats including decimal odds (e.g., 2.50), fractional odds (e.g., 6/4), and American odds (e.g., +150 or -200). Simply enter your stake amount, select your odds format, input the odds, and instantly see your potential returns.

Understanding Different Odds Formats
Decimal Odds
Decimal odds (e.g., 2.50) are the most common format in Europe, Australia, and Canada. They represent the total return you'll receive for every $1 wagered, including your stake. For example, odds of 2.50 mean you'll receive $2.50 for every $1 bet (including your original stake), giving you a profit of $1.50.
Fractional Odds
Fractional odds (e.g., 6/4 or 3/2) are popular in the UK and Ireland. The fraction represents the profit you'll make relative to your stake. For example, 6/4 odds mean you'll win $6 for every $4 you stake, plus your original stake back.
American Odds
American odds (e.g., +150 or -200) are commonly used in the United States. Positive odds (e.g., +150) show how much profit you'll make on a $100 bet. Negative odds (e.g., -200) show how much you need to bet to win $100. For instance, +150 means you'll win $150 profit on a $100 bet, while -200 means you need to bet $200 to win $100 profit.
