Expected Value (EV) Calculator

Expected Value (EV) is the average amount you expect to win or lose per decision over the long run. It is the single most important concept in poker mathematics. Every decision you make at the table either has positive expected value (+EV) or negative expected value (-EV).

A +EV decision is one that makes money over time, even if you lose in any individual instance. For example, if you call a $100 bet with 60% equity, you will lose that specific hand 40% of the time, but over thousands of repetitions, you profit. This is the foundation of professional poker strategy.

Why +EV matters long-term: Poker results over small samples are dominated by variance (luck). But over thousands of hands, your results will converge toward your cumulative EV. This is why professional players focus on making the best decision rather than worrying about individual outcomes.

EV accumulates with volume. A small edge per hand becomes significant over many hands. If your average decision is worth +$2 in EV and you play 1,000 hands per month, that is $2,000 in expected profit. This is why multi-tabling on crypto poker sites, where you can play more hands per hour, amplifies your edge.
