$
Enter your odds, your estimated true win chance, and a stake to see the value.
How to use it
Enter the offered decimal odds and your own estimate of the true probability. The calculator returns the expected value per unit staked and the edge implied by the gap between the price and your estimate.
What it means
A positive expected value means the price implies worse odds than the real chance you've estimated. Across many bets the maths leans in your favour, even though any single bet can lose. The edge shows up over volume, never as a guarantee on one result.
