Understanding Betting Odds

Betting odds represent the probability of an event occurring and determine how much you can win from a bet. This guide explains the three main formats used worldwide and how to calculate potential winnings.

Decimal Odds (Most Common in Africa)

Decimal odds are the easiest to understand and most commonly used in Africa. They show the total amount you'll receive (including your stake) for every unit bet.

Example: Odds of 2.50 mean you'll get $2.50 for every $1 bet (including your original $1)

Calculation: Profit = (Stake × Odds) - Stake

Fractional Odds (Traditional UK Format)

Fractional odds show the profit you'll make relative to your stake.

Example: 3/2 odds mean you'll win $3 for every $2 bet

Calculation: Profit = Stake × (Numerator/Denominator)

American Odds (Moneyline)

American odds use positive and negative numbers:

• Positive (+150): Shows profit on a $100 bet
• Negative (-150): Shows how much to bet to win $100

Converting Between Formats

• Decimal to Fractional: (Decimal - 1) = Fraction
• Fractional to Decimal: (Numerator ÷ Denominator) + 1
• Decimal to American: If odds ≥ 2.00: (Decimal - 1) × 100

Understanding Probability

You can convert odds to implied probability:

Formula: Probability = 1 ÷ Decimal Odds × 100

Example: Odds of 2.00 = 50% probability
