Frequently Asked Questions
How do you calculate expected value in betting?+
Multiply your profit if the bet wins by your estimated win probability, then subtract the expected loss from losing outcomes. Positive EV means the price is above your estimated fair value. Read the Positive EV guide.
What probability should I enter?+
Enter your estimated true win probability for the selection. The calculator compares that probability with the bookmaker odds to estimate expected value.
Is positive EV guaranteed profit?+
No. Positive EV is a long-term expectation, not a guarantee on a single bet. Results can still vary significantly in the short term.
