What Are Moneyline Odds?
Moneyline odds are the American format for expressing betting odds. Negative numbers (e.g., -150) indicate the favorite and show how much you need to bet to win $100. Positive numbers (e.g., +200) indicate the underdog and show how much you win on a $100 bet.
Moneyline odds are the standard format in US sports betting. They directly communicate the relationship between risk and reward without needing to calculate a stake-to-profit ratio.

Frequently Asked Questions
What does -110 mean?
A moneyline of -110 means you need to wager $110 to win $100 in profit. This is the standard vig (vigorish) for most point spread bets, representing the bookmaker's commission.
How do I calculate profit from moneyline odds?
For negative odds: Profit = Wager × (100/|odds|). For positive odds: Profit = Wager × (odds/100). For example, a $50 bet at +200 yields $50 × 2 = $100 profit.
What is the vig (juice)?
The vig is the bookmaker's commission built into the odds. It ensures the book makes money regardless of the outcome. The total implied probability for both sides of a bet typically exceeds 100%, with the excess being the vig.
