Convert betting odd types, calculate implied probability, and payout.
Begin by entering the odds you want to convert. Once you enter the odds in the format of your choice, you will see the converted odds along with the implied probability those odds represent. You can change the Bet amount to calculate the payout, profit and ROI.
American odds, also known as moneyline odds, are one of the most popular formats used in sports betting, especially in the United States. They are a way of expressing betting odds that can initially seem confusing, but with a bit of guidance, they become easy to understand and use.
American odds represent how much profit you could make based on a $100 bet. They are displayed as positive or negative numbers, which indicate different types of bets:
These odds help you quickly understand the risk and reward associated with each bet.
When you see a positive number, like +150, this indicates how much profit you would make on a $100 bet if you win. Here’s how it works:
This format is common when betting on the underdog. The higher the number, the less likely the team is expected to win, meaning a higher payout if they do.
Negative odds, like -120, show how much you would need to bet to make a $100 profit. These odds are typically used for favorites:
The larger the negative number, the more favored the team, and the lower the profit you’ll receive for a successful bet.
American odds are popular in the U.S. because they make it easy to gauge the favorite and underdog in a matchup and to quickly understand the profit potential. They are especially useful for sports bettors because:
While American odds are standard in the U.S., you may come across Decimal or Fractional odds, especially when betting internationally. Here’s a quick comparison:
Use this tool to convert American odds to other formats to simplify the process. This is especially useful for bettors comparing odds across different markets.
Decimal odds are the most commonly used odds format in Europe, Australia, and Canada. They are straightforward to understand and allow bettors to quickly see the total return on their wager, making them popular among both beginners and seasoned bettors. In this guide, we’ll break down how decimal odds work, how to read them, and how to calculate potential payouts.
Decimal odds show the total amount you will receive for every dollar wagered, including both your profit and your initial stake. Unlike American odds, decimal odds are always presented as positive numbers, typically with two decimal places.
Decimal odds make it easy to quickly calculate potential returns, as they directly display the multiplier for your stake.
The decimal number represents the total payout you receive per unit wagered. Here’s how it works:
Decimal odds are intuitive and allow for fast calculations, which is especially helpful for bettors who want to compare odds on multiple outcomes. Their simplicity makes them popular on betting platforms and among users who want a quick, easy way to see potential returns.
Decimal odds are commonly preferred in European and Canadian markets, but you may come across Fractional or American odds. Here’s a quick comparison:
Decimal odds offer simplicity, especially for bettors interested in the total payout rather than only the profit. Use this tool to convert decimal odds into other formats. It's especially useful when comparing betting odds across markets.
Fractional odds are one of the oldest and most traditional odds formats, especially popular in the UK and in horse racing. While they might look confusing at first, they’re simple to read once you know how they work. In this guide, we’ll break down what fractional odds are, how to read them, and how to calculate your potential winnings.
Fractional odds represent the ratio of profit to the stake. These odds are shown as fractions (like 5/1 or 7/4) and reflect the amount of profit you would make relative to the amount you wager.
Fractional odds are straightforward once you understand the concept of “stake to profit.”
In fractional odds, the first number represents the potential profit, and the second number represents the stake. Let’s break this down with examples:
When the odds have a higher first number (like 5/1), the bet has a high payout because it’s considered a less likely outcome. When the first number is smaller (like 1/4), the payout is lower because the outcome is more likely.
Fractional odds are popular among traditional bettors, particularly in horse racing and British sports markets. Here’s why they remain widely used:
You might encounter Decimal or American odds, especially when betting internationally. Here’s a quick comparison:
To convert fractional odds into other formats, you can use this odds converter tool, which is especially useful for comparing betting odds across markets.
To convert American odds to decimal odds, use these formulas:
For positive odds (e.g., +200) Divide the odds by 100 and add 1 Decimal Odds = (American Odds / 100) + 1.
For negative odds (e.g., -150) Divide 100 by the absolute value of the odds and add 1 Decimal Odds = (100 / abs(American Odds)) + 1.
For example, +200 converts to 3.00, and -150 converts to 1.67. Decimal odds represent the total payout per dollar wagered, including your original stake.
To convert American odds to fractional odds:
For Positive American Odds (+):
Fractional Odds = American Odds / 100
Example: +200 converts to 200 / 100 = 2/1
For Negative American Odds (−):
Fractional Odds = 100 / abs(American Odds)
Example: -150 converts to 100 / 150 = 2/3
To convert decimal odds to American odds:
If Decimal Odds > 2.00:
American Odds=(Decimal Odds − 1) × 100
Example: 3.50 converts to (3.50 − 1) × 100 = +250
If Decimal Odds < 2.00:
American Odds= −(100 / (Decimal Odds - 1))
Example: 1.75 converts to −(100 / (1.75 - 1)) = -133.33
To convert decimal odds to fractional odds:
Fractional Odds = Decimal Odds - 1
Then express the result as a fraction in its simplest form.
Example:
To convert fractional odds to American odds:
For Fractional Odds ≥ 1/1 (Evens or Greater than 1):
American Odds = (Numerator / Denominator) x 100
Example: 5/2 converts to (5/2) x 100 = +250
For Fractional Odds < 1/1 (Less than 1):
American Odds = -(Denominator / Numerator) x 100
Example: 2/5 converts to -(5/2) x 100 = -250
To convert fractional odds to decimal odds:
Decimal Odds = (Numerator / Denominator) + 1
