Decimal odds show everything you get back for each 1 you bet, stake included. At 2.50, a $10 bet returns $25: $15 profit plus your $10.
They're standard in Europe, Canada and Australia, and they're the easiest format to calculate with. A parlay's odds are simply every leg's decimal odds multiplied together, and implied probability is 1 divided by the decimal odds.
2.00 is even money. Below 2.00 is a favorite, above it an underdog.
How it works
Decimal odds always include your stake, which is what makes them so easy to use. Multiply your stake by the odds and you have your total return. Subtract your stake to get the profit.
Because everything is one number, comparing prices is simple: a higher number always pays more. That's why many bettors prefer decimal odds for line shopping, even when their sportsbook defaults to American odds.
| Decimal | American | Implied chance |
|---|---|---|
| 1.50 | -200 | 66.7% |
| 1.91 | -110 | 52.4% |
| 2.00 | +100 | 50.0% |
| 2.50 | +150 | 40.0% |
| 4.00 | +300 | 25.0% |
A common mistake is treating decimal odds as profit. 2.50 doesn't mean you win $2.50 on a $1 bet. It means you get $2.50 back, of which $1.50 is profit. Decimal odds are never below 1.00, and a price of 1.01 means almost no profit at all.
Examples
- Example 1
1.91 is the same price as -110 in American odds and 10/11 in fractional odds.
- Example 2
A $25 bet at 3.40 returns $85 in total, which is $60 profit.
- Example 3
A two-leg parlay at 1.80 and 2.10 has odds of 3.78, so a $10 stake returns $37.80.
- Example 4
Odds of 2.20 imply a 45.45% chance (1 ÷ 2.20).

Are decimal odds better than American odds?
They show the same prices in a different way. Decimal odds are easier to compare and to use for parlay maths, so many bettors switch to them.
