1. American Odds Formats (+ / -)
American odds are centered around $100 baseline calculations:
- Negative (-) Odds: Indicates the favorite. The number represents how much money you must bet to profit $100. (e.g., -150 means bet $150 to profit $100).
- Positive (+) Odds: Indicates the underdog. The number represents how much profit you win on a $100 wager. (e.g., +135 means bet $100 to profit $135).
2. Decimal Odds (Popular in International Markets)
Decimal odds express total payout (initial stake + profit) per 1 unit wagered.
Example: Decimal 2.35 = $100 stake x 2.35 = $235 total return ($135 profit).
