Type any one of the three and the others follow. The implied chance is what the price says about the probability, before commission.
Result
These figures assume your bets are matched in full at the prices you typed and that commission is charged on net winnings at the rate you entered. The exchange's own rules and rounding are the only ones that count. 18+ only.
Under the hood
The formula
- Implied chance = 1 / decimal odds. At 2.50 the price implies a 40% chance.
- Fractional a/b = decimal - 1, written as a fraction: 2.50 is 3/2 (1.5 to 1).
- American: if decimal is 2.00 or more, + (decimal - 1) x 100; otherwise -100 / (decimal - 1). 2.50 is +150; 1.50 is -200.
- After commission, a winning back bet keeps profit x (1 - commission), so the effective decimal odds are 1 + (odds - 1) x (1 - commission).
