Frequently Asked Questions
What is expected value (EV) in betting?
Expected value is the average profit or loss you would expect if you placed the same bet many times. Positive EV means the bet is profitable long term; negative EV means it is not.
How is expected value calculated?
EV = (win probability times profit if you win) minus (loss probability times stake). This calculator computes it from your odds, estimated win probability and stake.
What is a good EV percentage?
Any positive EV is theoretically profitable. Sharp bettors often target +2% or higher; the larger the edge, the faster a bankroll grows over time.
How do I estimate my win probability?
Use the no-vig price from a sharp book, your own model, or a consensus of odds. Your EV is only as accurate as the win probability you feed in.
