Odds Converter

Understanding different odds formats is a fundamental skill for any serious bettor. Whether you are looking at European decimal odds, British fractions, or American moneyline prices, our Odds Converter instantly translates them into your preferred format while showing the underlying win probability.

Understanding the Inputs
Start by entering your Bet Amount to see your potential returns in real-time. You can then enter a value into any of the four odds fields. As soon as you type in one box, all other formats—and your projected payout—will update automatically.

The Different Formats
• Fraction: Represents the ratio of the profit to the stake (e.g., 1.10 profit for every 1 staked).

• Decimal: The most common international format, representing the total return (Stake x Odds).

• American: Shows how much you need to bet to win $100 (-), or how much you win on a $100 bet (+).

• Probability: The percentage chance of the outcome occurring as implied by the odds.

Why use this tool?
By converting odds to Probability, you can easily compare a bookmaker’s price against your own calculated edge. If the implied probability is lower than your predicted win percentage, you have found a positive expected value (+EV) bet.

Pro Tip: Once you have converted your odds and found your probability, head over to our EV Calculator to see exactly how much value your bet holds.
