How to convert Decimal odds to American odds
This decimal odds to American odds converter helps you switch between two common betting odds formats in seconds. Type in your decimal odds and the matching American odds will be calculated automatically.
How decimal odds are converted to American odds
If the decimal odds are 2.00 or higher, subtract 1 and multiply by 100 to get positive American odds. If the decimal odds are below 2.00, divide -100 by decimal odds minus 1 to get negative American odds.
For example, decimal odds of 2.50 convert to American odds of +150.
Worked example
Convert decimal odds of 3.25 to American odds
Since 3.25 is greater than or equal to 2.00, the American odds will be positive.
Use the formula (decimal odds - 1) × 100.
(3.25 - 1) × 100 = 225.
The American odds are +225.
Important note for this conversion

Common conversion mistake
A common mistake with American odds is forgetting that positive and negative values use different formulas. Always check the sign before converting.
Decimal odds explained
Decimal odds are the most widely used odds format in Europe, Canada, and Australia. They show the total payout for every 1 unit staked, including your original stake. For example, decimal odds of 2.50 return 2.50 for every 1 wagered, which means 1.50 profit plus the original 1 stake.
American odds explained
The sign is the key to reading American odds. Positive prices indicate underdogs and larger returns per 100 staked, while negative prices indicate favourites and a larger required stake to win 100. Once converted, they map cleanly to decimal and implied probability.
