American vs. Decimal Odds Explained

Understanding odds is the foundation of sports betting. Odds represent the probability of an event occurring and determine how much profit you make.

American Odds (-/+)

Common in the United States.

• Negative Numbers (-110): You must bet this amount to win $100.
• Positive Numbers (+150): You win this amount for every $100 bet.

Decimal Odds (2.00)

The global standard. It represents the total payout (Stake + Profit). Formula: Stake x Odds = Total Return.

Implicit Probability

This is the most important concept for sharps. It converts odds into a percentage. If the "Real World" probability is higher than the "Implied" probability, you have an edge.
