Expected Value (EV) Betting Calculator

Enter the odds, the chance you give the bet of winning and a stake. The calculator shows what the bet returns on average, and the win rate the price needs to break even.

Example: a $100 bet at +120 that you think wins 50% of the time has an expected value of +$10, which is 10% of the stake. The price breaks even at a 45.5% win rate.

A positive number means the price pays more than the risk you are taking, if your win chance is right. The result is only as good as that estimate, so compare it with the fair chance from the no-vig calculator first.
