Expected value calculator
Calculate the EV of a bet from your probability estimate and the offered odds. Change the inputs to explore where the price becomes attractive.
EV stands for expected value. In betting, it calculates the mathematical average of hypothetical outcomes when the same scenario is repeated many times.
Compare your probability estimate with the offered odds to calculate EV. Change either input to see how the expected return responds.
EV = probability of winning x profit if you win - probability of losing x amount staked.
Example: if you estimate a 52% chance at odds of 2.10, the estimate exceeds the break-even probability of 47.62%.
