Understanding Betting Odds Formats

Our Odds Converter instantly translates between the four major betting odds formats used by bookmakers worldwide. Whether you're comparing odds across platforms, calculating potential payouts, or learning about different formats, this tool provides accurate conversions in real-time.

Decimal Odds

2.50

Popular in Europe, Australia, and Canada, decimal odds represent the total return including your stake.

Formula: Total Return = Stake × Decimal Odds

Example: $10 × 2.50 = $25 return ($15 profit)

Fractional Odds

6/4

Traditional UK format showing potential profit relative to stake, common in horse racing.

Formula: Profit = Stake × (Numerator ÷ Denominator)

Example: $10 × (6 ÷ 4) = $15 profit ($25 total)

American Odds

+150 / -200

Used in the US, showing profit on $100 stake (+) or stake needed to win $100 (-).

Formula (+): Profit = Stake × (Odds ÷ 100)
Formula (-): Profit = Stake × (100 ÷ |Odds|)

Example: $100 at +150 = $150 profit ($250 total)

Implied Probability

40%

Represents the bookmaker's assessment of outcome likelihood, used to identify value bets.

Formula: Probability = (1 ÷ Decimal Odds) × 100

Example: (1 ÷ 2.50) × 100 = 40% probability
