Understanding Moneyline Odds
How American Odds Work
American betting odds, also known as moneyline odds, are centered around $100 and indicate either how much you can win or how much you need to bet, depending on whether the team is favored or not.
Reading the Signs
- Negative (-): Favorite - amount to bet for $100 profit
- Positive (+): Underdog - profit on $100 bet
- ±100: Even odds - 50/50 chance
Conversion Formulas
Probability to Odds:
If f = (1-p) / p > 1: +odds = f × 100
If f < 1: -odds = 100 / f
Payout Calculation
- Underdog (+): Profit = (stake × odds) / 100
- Favorite (-): Profit = stake / (|odds| / 100)
