How to read odds

Odds represent the likelihood of an event occurring and are commonly used in gambling, betting, and probability discussions. There are three main formats for odds: fractional odds, decimal odds, and moneyline odds. Here's how to interpret them:


1. Fractional Odds (e.g., 5/1, 3/2):

  • How to read:
    • The first number (numerator) is how much you can win relative to your stake.
    • The second number (denominator) is your stake.
  • Example:
    • 5/1: For every $1 you bet, you win $5 (plus your original stake back, for a total of $6).
    • 3/2: For every $2 you bet, you win $3.
  • Calculation of implied probability: this is picture

2. Decimal Odds (e.g., 6.00, 2.50):

  • How to read:

    • The number represents the total return (including your stake) for every $1 bet.
  • Example:

    • 6.00: A $1 bet returns $6 (profit = $5).
    • 2.50: A $1 bet returns $2.50 (profit = $1.50).
  • Calculation of implied probability:

3. Moneyline Odds (e.g., +200, -150):

  • Positive odds (+): Represent how much profit you'd make on a $100 bet.
  • Negative odds (-): Represent how much you need to bet to win $100.
  • Examples:
    • +200: A $100 bet returns $200 in profit (total payout = $300).
    • -150: You need to bet $150 to win $100 (total payout = $250).
  • Calculation of implied probability: this is picture
