Expected Value (EV) Calculator
Enter the odds and your own probability estimate. See how much value the bet has, relative to the line.

How it works
Expected value = (your win probability x potential profit) minus (your lose probability x stake). A positive EV means that, on average, you profit from this bet. A negative EV means the house has the edge.
The key is your probability estimate, not the book's implied probability. If the book has -110 (52.4% implied) but you believe the true probability is 55%, you have a 2.6% edge. When your estimate matches the book's line exactly, EV is always $0.
