Decimal Odds Format
Decimal-format odds show the complete payout per unit staked, including your initial stake, simplifying the math by simply multiplying your stake by the decimal number displayed.
This format dominates European, Australian, and Canadian markets due to its straightforward nature, enabling bettors to instantly calculate expected winnings without further mathematical transformations or adjustments.

| 2.50 | 6/4 | +150 | 40% |
| 1.91 | 10/11 | -110 | 52.36% |
To transform decimal odds to fractional odds, deduct 1 and present as a fraction. For American-style odds, if decimal is 2.00 or greater, use (decimal – 1) × 100 for positive-value odds; if below 2.00, use -100 ÷ (decimal – 1) for negative-value odds.
