Type odds in any format — American, decimal, or implied probability — and instantly see the other two. The clean, no-nonsense converter for anyone reading a line.
Implied probability includes the house margin. Strip it with the free no-vig calculator to see the fair price.
American — the US format: +150 means a $100 stake wins $150; -150 means you stake $150 to win $100.
Decimal — total return per unit staked: 2.50 means $1 returns $2.50 (a $1.50 profit). Common outside the US and on exchanges.
Implied probability — the chance the price implies. American -150 → 60%, +150 → 40%. This is what the market thinks (vig included) — compare your own estimate against it to find an edge, then strip the vig to see the fair line.
