American odds
American (moneyline) odds show the profit on a $100 stake for underdogs (+150 wins $150) and the stake needed to win $100 on favorites (-150 risks $150 to win $100). They're standard at US sportsbooks.

How it works
Odds converter: the basics
Decimal odds
Decimal odds show the total return for each 1 staked, including your stake. 2.50 returns 2.50 for every 1 you bet, so the profit is 1.50. They're the easiest format for working out payouts and parlays.
Fractional odds
Fractional odds show profit relative to stake. 5/2 means you win 5 for every 2 you bet. They're traditional in the UK and Ireland, especially for horse racing.
Implied probability
Implied probability is the chance of winning that the odds suggest: 1 divided by the decimal odds. -110 implies 52.4%, so you need to win more often than that to make a profit at that price.

FAQ
Odds converter questions
How do I convert American odds to decimal?
For positive odds, divide by 100 and add 1 (+150 becomes 2.50). For negative odds, divide 100 by the odds without the minus sign and add 1 (-150 becomes 1.67).
How do I convert decimal odds to American?
If the decimal odds are 2.00 or higher, subtract 1 and multiply by 100 (2.50 becomes +150). If they're below 2.00, divide -100 by the decimal odds minus 1 (1.67 becomes -150).
What does -110 mean?
You bet $110 to win $100. As decimal odds it's 1.91, as fractional it's 10/11, and it implies a 52.4% chance of winning.
What is implied probability?
The win chance built into the odds, worked out as 1 ÷ decimal odds. It includes the sportsbook's margin, so the implied chances of every outcome add up to more than 100%. Use the no-vig calculator to remove it.
