How It Works

Moneyline odds (also called American odds) are the standard format used in the United States. They can be positive or negative, indicating underdogs and favorites respectively.

How Moneyline Odds Are Converted:

Positive moneyline (e.g., +150): Shows how much you win on a $100 bet

Decimal = (Moneyline / 100) + 1

Negative moneyline (e.g., -200): Shows how much you need to bet to win $100

Decimal = (100 / |Moneyline|) + 1

Example:

If you have moneyline odds of +150:

  • Decimal = (150 / 100) + 1 = 2.50
  • Fractional = 3/2
  • Implied Probability = 40%
