Poker EV Calculator

Last updated: May 16, 2026

Poker EV (Expected Value) formula: EV = Σ(probability × outcome). For all-in: EV = (equity × pot won) − ((1−equity) × bet lost). Positive EV decisions win money long-term. This page covers the EV formula, standard variants (all-in, bluff, semi-bluff, value bet), and worked examples for each.

Definitions

EV (Expected Value)
Sum of probability × outcome for all possible results. Standard decision metric in poker.
Equity
Win probability at any decision point. Equity × pot = expected pot-share if hand played to showdown.
Fold Equity
The portion of EV from opponent folding. Required for bluffs to be profitable.
Pot Odds
Call amount divided by total pot. Defines minimum required equity to call profitably.
ICM EV
Tournament EV measured in dollar equity (not chips). Differs from chip EV due to non-linear chip-to-dollar conversion.

Frequently Asked Questions

What is EV in poker?

EV (Expected Value) is the average outcome of a poker decision across all possible results, weighted by their probabilities. A +EV decision wins money long-term; a -EV decision loses money long-term. Individual hand results don't determine if a decision was +EV — only the math of probabilities and outcomes does. Top players make decisions based on EV, not on what happened in a single hand.

How do you calculate EV in poker?

Basic formula: EV = Σ(probability × outcome). For an all-in: EV = (equity × pot you win) − ((1−equity) × amount you lose). Example: $100 pot, 60% equity all-in for $50: EV = (0.6 × 150) − (0.4 × 50) = 90 − 20 = +$70. Always positive when equity exceeds the required pot odds.

What is bluff EV?

Bluff EV = (Fold% × Current Pot) − (Call% × Bet Amount). Example: $100 pot, bet $50, opponent folds 60%: EV = (0.6 × 100) − (0.4 × 50) = 60 − 20 = +$40. The bluff is +EV when fold% > bet/(pot+bet) — for half-pot, 33% folds breaks even.

What's the difference between EV and equity?

Equity is your share of the pot based on win probability (e.g., 60%). EV is the dollar value of a decision — combines equity with pot odds and bet size. A high-equity hand can be -EV if you have to call a huge bet; a low-equity hand can be +EV if you can win uncalled with fold equity (semi-bluff). EV is the decision metric; equity is one input to it.

Can a hand be -EV but profitable in tournaments?

Yes — when bounty value (PKO tournaments) or ICM dollar equity outweighs chip EV. Conversely, a +chipEV decision can be -dollarEV due to ICM pressure on the bubble. Tournament pros use ICM-aware tools (HRC) to compute true dollar EV. Cash games: chip EV = dollar EV directly (chips = dollars 1:1).

How accurate are EV calculations?

EV calculations are mathematically exact given accurate inputs. The challenge is estimating opponent ranges and fold frequencies — these are inputs to EV that have uncertainty. Solver-derived EV is highly accurate at equilibrium; exploitative EV depends on your opponent reads. Use EV calculations as guides, not absolute truths.
