Enter odds
e.g. 2.50
Tip: Odds of 2.50 return 2.50 for every 1 unit staked (including your stake).
e.g. type 2.50 (decimal) — that's +150 American, 3/2 fractional, and a 40% implied chance of winning.
Why it matters
Decimal, American, and fractional are just three ways of writing the same price. Each one maps to an implied probability — the chance of winning the bookmaker has built into the odds.
