How odds formats work
- American: −150 means risk $150 to win $100; +150 means risk $100 to win $150.
- Decimal: total return per $1, stake included. 2.50 returns $2.50.
- Fractional: profit ÷ stake. 3/2 wins $3 for every $2.
- Implied chance: 1 ÷ decimal odds. It includes the sportsbook’s cut until you remove the vig.
