Why Use a Betting Odds Converter?

  • Compare Across Formats: Odds are displayed differently around the world. Our converter lets you switch between formats effortlessly, so you can compare bets no matter where they’re from or how they're presented.
  • Eliminate Confusion: Misinterpreting odds can lead to costly mistakes. Our tool removes the guesswork by providing clear, accurate conversions in real time.
  • Bet with Confidence: Knowing exactly what the odds represent helps you make well-informed decisions and avoid being misled by unfamiliar formats.

Implied Probability – See the True Value

One of the most important features of our odds converter is that it shows you the implied probability of each set of odds. This is the bookmaker’s estimate of how likely an outcome is to occur, based on the odds they offer.

Why This Matters:

  • It allows you to assess whether a bet is fairly priced.
  • You can compare the bookmaker’s implied probability to your own research or predictions.
  • It helps identify value bets—those where you believe the true probability is higher than the odds suggest.

Real-World Example: Spotting a Value Bet

Let’s say you’re considering a football match where a bookmaker offers odds of 3.00 (Decimal) on Team A to win. Using our converter:

  • Decimal Odds: 3.00
  • Fractional Odds: 2/1
  • American Odds: +200
  • Implied Probability: 33.3%

Now, based on your own analysis, you believe Team A has at least a 45% chance of winning. That means the odds are offering a greater payout than the risk you’ve assessed, which is the definition of a value bet.

By recognizing this mismatch, you can make a calculated decision to place a bet where the potential reward outweighs the actual risk.

Take Control of Your Betting Strategy

With our Betting Odds Converter, you're not just changing formats—you’re changing the way you think about betting. By understanding both the odds and the implied probabilities behind them, you’ll be equipped to:

  • Compare bookmakers more effectively
  • Recognize profitable opportunities
  • Make sharper, more strategic decisions

Understanding the Three Main Odds Formats

Our Betting Odds Converter supports the three most widely used formats: Decimal, Fractional, and American. Each format presents the same information in a different way, and understanding them is key to comparing bets and evaluating value across markets.

Decimal Odds (Used in Europe, Canada, Australia, and Asia)

Format Example: 2.50

  • How It Works: Decimal odds show the total return for every 1 unit staked, including your original bet.
  • Calculation:
    Total Payout = Stake × Decimal Odds
    (e.g. a $10 bet at 2.50 returns $25 — $15 profit + $10 stake)
  • Implied Probability Formula: 1 / Decimal Odds

    Why Use It: It’s the most straightforward format and easiest to use for quick calculations.

    Fractional Odds (Popular in the UK and Ireland)

    Format Example: 6/4 or 3/1

    • How It Works: Fractional odds show your profit relative to your stake.
    • Calculation:
      Profit = Stake × (Numerator / Denominator)
      (e.g. a $10 bet at 3/1 returns $30 profit + $10 stake = $40 total)
    • Implied Probability Formula:
      Denominator / (Numerator + Denominator)

    Why Use It: Common in horse racing and traditional UK betting, it expresses how much profit you get relative to your stake.

    American Odds (Used in the United States)

    Format Example: +200 or -150

    • How It Works:
      • Positive odds (e.g. +200): show how much profit you make on a $100 bet.
        • A $100 bet at +200 returns $200 profit + $100 stake = $300 total
      • Negative odds (e.g. -150): show how much you need to bet to win $100.
        • A $150 bet at -150 returns $100 profit + $150 stake = $250 total
    • Implied Probability Formula:
      • For positive odds: 100 / (Odds + 100)
      • For negative odds: Odds / (Odds + 100)

    Why Use It: Standard in the U.S. and useful for understanding how heavily a team or player is favored.
