Tools · +EV calculator
Compare the price you can get against your fair (no-vig) line to find long-term edge and the recommended Kelly stake. Learn more.
+EV bets only pay out across hundreds of wagers, so size sanely. Full Kelly grows a bankroll fastest but with brutal swings; half or quarter Kelly is the usual default if you are not certain your fair line is right. Our live +EV feed compares book prices against a fair line built from market consensus and surfaces every edge as it appears.
