About Betting Odds

Betting odds represent the probability of an event occurring and determine the payout you receive if your bet wins. Different regions use different odds formats.

Decimal Odds (European)

Decimal odds represent the total payout (including your stake) per unit wagered.

  • Format: A single decimal number (e.g., 2.50)
  • Payout Formula: Stake × Decimal Odds
  • Profit Formula: Stake × (Decimal Odds - 1)
  • Example: $100 at 2.50 odds = $250 total payout ($150 profit)
  • Implied Probability: 1 / Decimal Odds
Fractional Odds (UK/Irish)

Fractional odds show the profit relative to the stake.

  • Format: X/Y (e.g., 3/2 or 6/4)
  • Profit Formula: Stake × (Numerator/Denominator)
  • Payout Formula: Stake + (Stake × (Numerator/Denominator))
  • Example: $100 at 3/2 odds = $250 total payout ($150 profit)
  • Implied Probability: Denominator / (Numerator + Denominator)
American Odds (US)

American odds can be either positive (+) or negative (-) numbers.

  • Positive (+) Format: Shows how much profit you'd make on a $100 stake
  • Negative (-) Format: Shows how much you need to stake to make $100 profit
  • Example (+): $100 at +150 odds = $250 total payout ($150 profit)
  • Example (-): $200 at -200 odds = $300 total payout ($100 profit)
  • Implied Probability (Positive): 100 / (American Odds + 100)
  • Implied Probability (Negative): |American Odds| / (|American Odds| + 100)
Implied Probability

The implied probability represents the likelihood of an outcome occurring according to the odds.

  • Format: Percentage (e.g., 40%)
  • Decimal Conversion: 100 / Probability Percentage
  • Example: 40% probability = 2.50 decimal odds
Understanding Value in Betting

Value betting is when you believe the probability of an outcome is higher than what the odds imply.

  • Value Formula: (Your Assessed Probability × Decimal Odds) - 1
  • Positive Value: Indicates a potentially profitable bet over time
  • Example: If you believe a team has a 50% chance of winning (implied odds of 2.00), but the bookmaker offers 2.50, there's positive expected value
