Odds Converter

American, decimal, and fractional odds all express the same thing differently. American odds show profit relative to $100 (+150 wins $150 on $100; -200 requires $200 to win $100). Decimal odds show total return per dollar staked (2.50 returns $2.50 including the stake). Fractional odds show profit as a fraction of the stake (3/2 wins $3 per $2). Type a value into any field and the rest update instantly.

The converter also surfaces the breakeven win probability for any price, plus your potential winnings and payout for a given bet amount. It is handy whenever you are comparing offshore or international books that quote different formats, or sanity-checking a payout before you lock a ticket in.
