Decimal Odds Calculator

Decimal odds represent the total return you receive for every $1 wagered, including your original stake. For example, decimal odds of 2.50 mean a $100 bet returns $250 total — $150 profit plus your $100 stake back.

Profit = (Decimal Odds − 1) × Bet Amount. So for odds of 2.50 and a $100 bet, profit = (2.50 − 1) × $100 = $150. The total payout including your stake would be $250.

If decimal odds are 2.00 or higher, American odds = (Decimal − 1) × 100. If decimal odds are below 2.00, American odds = −100 / (Decimal − 1). For example, decimal 2.50 converts to +150 American odds.

Subtract 1 from the decimal odds to get the fractional equivalent. Decimal 2.50 becomes 1.50/1, which simplifies to 3/2. You can reduce the fraction by finding the greatest common divisor of the numerator and denominator.

Implied probability is the likelihood of an outcome as suggested by the odds. It is calculated as: Implied Probability = 1 / Decimal Odds × 100. For decimal odds of 2.50, the implied probability is 40%, meaning the bookmaker prices that outcome as having a 40% chance of occurring.

Decimal odds must always be greater than 1.00. Odds of exactly 1.00 would mean no profit regardless of how much you bet. In practice, most sportsbooks offer a minimum of around 1.01 for near-certain outcomes.

Yes. Unlike American or fractional odds which only represent profit, decimal odds already include your stake in the return figure. This makes them straightforward to use — simply multiply your bet amount by the decimal odds to get the total payout.

Decimal odds are widely considered the most straightforward format because the total payout calculation is a single multiplication. They are the standard format used in Europe, Australia, and Canada, and are increasingly common on US sportsbooks.
