Betting odds are essential for understanding how much you can win on a bet. Whether you are betting on sports, horse racing, or casino games, https://thetotosite.com, knowing how to read decimal, fractional, and American odds will help you make better decisions.
In this guide, we will explain the three main types of betting odds, how to convert between them, and how to calculate implied probability for smarter betting.
1. What Are Betting Odds?
Betting odds tell you:
- How much you can win based on your wager.
- The likelihood of an event happening according to the sportsbook.
Different countries use different formats, but all three types of odds—decimal, fractional, and American—mean the same thing. You can convert between them to compare bets across different sportsbooks.
2. Decimal Odds (European Style)
What Are Decimal Odds?
Decimal odds are the most common format in Europe, Canada, and Australia. They are easy to understand because they include your stake in the total payout.
How to Read Decimal Odds
Decimal odds are written as a single number, such as:
- 2.50
- 1.75
- 4.00
How to Calculate Winnings
Formula:
Winnings = Stake × Decimal Odds
Example:
- If you bet $10 on 2.50 odds, your total payout is:
$10 × 2.50 = $25 total payout ($15 profit + $10 stake).
How to Calculate Implied Probability
Formula:
Probability (%) = (1 ÷ Decimal Odds) × 100
Example:
- If the odds are 2.50, the probability is:
(1 ÷ 2.50) × 100 = 40% chance of winning.
When to Use Decimal Odds
- If you prefer a simple payout calculation.
- If you are betting with European, Australian, or Canadian sportsbooks.
3. Fractional Odds (UK Style)
What Are Fractional Odds?
Fractional odds are mainly used in the UK and Ireland, especially in horse racing. They are written as fractions, such as:
- 5/1
- 7/2
- 10/3
How to Read Fractional Odds
- The first number (numerator) is the profit you win.
- The second number (denominator) is the amount you must bet.
How to Calculate Winnings
Formula:
Winnings = (Stake × Fractional Odds) + Stake
Example:
- If you bet $10 on 5/1 odds, your total payout is:
($10 × 5) + $10 = $60 total payout ($50 profit + $10 stake).
How to Calculate Implied Probability
Formula:
Probability (%) = Denominator ÷ (Denominator + Numerator) × 100
Example:
- If the odds are 5/1, the probability is:
1 ÷ (1 + 5) × 100 = 16.67% chance of winning.
When to Use Fractional Odds
- If you bet on horse racing or UK sportsbooks.
- If you want to compare potential profits easily.
4. American Odds (Moneyline Odds – U.S. Style)
What Are American Odds?
American odds, also called Moneyline odds, are the standard format in the United States. They can be positive (+) or negative (-).
How to Read American Odds
- Positive Odds (+) – Show how much profit you win on a $100 bet.
- Negative Odds (-) – Show how much you need to bet to win $100.
How to Calculate Winnings for Positive Odds (+)
Formula:
Winnings = (Stake × Positive Odds) ÷ 100
Example:
- If you bet $10 on +200 odds, your total payout is:
($10 × 200) ÷ 100 = $30 total payout ($20 profit + $10 stake).
How to Calculate Winnings for Negative Odds (-)
Formula:
Winnings = (Stake ÷ Negative Odds) × 100
Example:
- If you bet $10 on -200 odds, your total payout is:
($10 ÷ 200) × 100 = $15 total payout ($5 profit + $10 stake).
How to Calculate Implied Probability for American Odds
For positive (+) odds:
Probability (%) = 100 ÷ (Positive Odds + 100) × 100
For negative (-) odds:
Probability (%) = Negative Odds ÷ (Negative Odds + 100) × 100
Examples:
- +200 odds → 100 ÷ (200 + 100) = 33.33% probability.
- -200 odds → 200 ÷ (200 + 100) = 66.67% probability.
When to Use American Odds
- If you bet with U.S. sportsbooks.
- If you prefer betting on favorites and underdogs.
5. How to Convert Between Odds Formats
You can convert between fractional, decimal, and American odds using these formulas:
Fractional to Decimal
(Numerator ÷ Denominator) + 1
Example:
- 5/1 → (5 ÷ 1) + 1 = 6.00
Decimal to Fractional
(Decimal Odds – 1) as a fraction
Example:
- 3.00 → 3.00 – 1 = 2/1
American to Decimal
For positive (+) odds:
(American Odds ÷ 100) + 1
For negative (-) odds:
(100 ÷ Absolute American Odds) + 1
Examples:
- +200 → (200 ÷ 100) + 1 = 3.00
- -200 → (100 ÷ 200) + 1 = 1.50
Decimal to American
For decimal odds > 2.00:
(Decimal – 1) × 100
For decimal odds < 2.00:
-100 ÷ (Decimal – 1)
Examples:
- 3.00 → (3.00 – 1) × 100 = +200
- 1.50 → -100 ÷ (1.50 – 1) = -200
