American Odds (Moneyline) are centered around the number 100, focusing on how much you win or how much you risk. While popular in the US, they are difficult to use for calculating total payouts or parlay multipliers.
Decimal Odds are the global standard for efficient betting. They simply represent the Total Payout per $1 wagered. Use the converter below to switch from US style to the Decimal format used by exchanges and professional bettors.

- Enter American Odds: Type in the moneyline value.
- For favorites, use a minus sign (e.g., -150).
- For underdogs, use a plus sign (e.g., +200) or just the number.

Why Convert to Decimals?
If you bet $50 on odds of 2.50, the math is simple: $50 × 2.50 = $125 Total Return. Doing this math with American odds (+150) requires more steps. Decimals are also essential if you plan to use Betting Exchanges like Betfair or Matchbook, which do not support American formats.
