How to Use the Bet Payout Calculator
Understanding how much you stand to win on a sports bet is crucial for effective bankroll management. Our Bet Payout Calculator simplifies the math behind different odds formats, allowing you to focus on your betting strategy rather than the arithmetic.
Understanding Different Odds Formats
Decimal Odds: Most common in Europe and Australia. Simply multiply your stake by the odds to get the total payout.
Fractional Odds: Popular in the UK and Ireland (e.g., 5/1). The first number is what you win relative to the second number (the stake).
American Odds: Used in the US. Positive numbers (+) indicate how much profit you make on a $100 bet. Negative numbers (-) indicate how much you must bet to make $100 profit.
Real-World Examples
Example 1 (Decimal): If you bet 100 units on a team with 2.50 odds, your total payout is 250 (100 x 2.50). Your profit is 150.
Example 2 (Fractional): A 20 unit bet at 4/1 odds means for every 1 unit bet, you win 4. Your profit is 80 (20 x 4) and total payout is 100.
Example 3 (American): A 50 unit bet at -200 odds (the favorite) requires you to bet 200 to win 100. Thus, a 50 bet yields 25 in profit, for a 75 total payout.
