Odds converter

Type a price as American odds, decimal odds or a chance to win, and see it the other two ways, with what $100 wins. Nothing you enter is saved.

American odds

How the conversion works

Plus American odds to decimal: 1 + price ÷ 100. +150 is 2.50.
Minus American odds to decimal: 1 + 100 ÷ price, ignoring the minus. −200 is 1.50.
Decimal odds to the implied chance: 1 ÷ decimal. 2.50 is 40%.

The implied chance is the win rate a price needs just to break even. On a real sportsbook the two sides add up to more than 100%: the extra is the book's margin. How to take it out.
