Betting calculators

Enter a price in any format and read it in the other two, with the probability the market implies.

Implied probability40%
The share of outcomes the price implies. The sportsbook's margin is part of it, so the three implied probabilities of a market add up to more than 100%.
A possible payout is not a promise. No price guarantees a result, and no strategy guarantees profit. Bet only what you can afford to lose. If gambling stops being fun, step away. Confidential U.S. support: 1-800-GAMBLER.
