Poker ICM Calculator
Estimates your Independent Chip Model (ICM) dollar equity in a poker tournament from your stack and the payout structure. Critical for making correct push/fold and call decisions at final tables and pay jumps where chip-EV diverges sharply from dollar-EV.

About this calculator
ICM (the Independent Chip Model) converts tournament chips into prize-money equity. Chips are not worth a fixed amount of money: doubling your stack does not double your equity when several places are paid. This calculator uses the Malmuth-Harville model that ICM software uses: the chance of finishing first equals your share of the chips; the chance of finishing in each later place is found by removing the player who finished above and repeating with the remaining stacks. Your ICM value is Σ P(finish in place k) × payout_k. Variables: yourStack (your chips), totalChips (all chips in play), playersLeft (players still in), prizePool (dollars still to be paid), payouts (percent of the prize pool for 1st, 2nd, 3rd and so on, separated by commas; places not listed pay nothing). Because this form asks only for your own stack, it assumes the other players' chips are split equally among them. Real stack distributions change the answer, especially for the places below first, so use full ICM software (ICMIZER, HoldemResources Calculator) when exact stacks matter. Key pattern: ICM gives big stacks less than their chip share (chip-EV) and short stacks more, because a short stack can still ladder into the paid places. With one player left, or with a winner-takes-all payout, ICM equals chip share × prize pool.
How to use
Example 1: You hold 45,000 of 150,000 chips with 3 players left and a $10,000 prize pool paying 50/30/20. The two opponents are assumed to hold 52,500 each. Step 1: P(1st) = 45,000 / 150,000 = 30%. Step 2: P(2nd) = 70% × 45,000 / (45,000 + 52,500) = 32.3%. Step 3: P(3rd) = 100% − 30% − 32.3% = 37.7%. Step 4: ICM value = 0.30 × $5,000 + 0.323 × $3,000 + 0.377 × $2,000 ≈ $3,223.08, above your $3,000 chip share. Example 2 (the default inputs): 15,000 of 50,000 chips, 5 players left, $1,000 pool paying 50/30/20. P(1st) = 30%, P(2nd) = 25.5%, P(3rd) = 20.6%, so ICM value ≈ $267.48, below the $300 chip share because 4th and 5th pay nothing.
Frequently asked questions
Why does ICM matter more at the final table than during early tournament play?
Early in a tournament, the payout structure has little practical effect on individual hand decisions because survival across many levels matters more than any single equity shift. At the final table, especially near pay jumps, each chip gain or loss directly affects your dollar equity in a nonlinear way. Doubling up as the chip leader may only increase your ICM equity by 20%, while busting the short stack could increase everyone's equity by hundreds of dollars. This asymmetry means calling all-ins with marginal chip-EV edges can be massive ICM mistakes. Short-stack survival becomes disproportionately valuable as pay jumps approach, which is why short stacks correctly fold hands they would shove in cash games.
How does this ICM calculation differ from full ICM software?
The finishing-order math here is the same Malmuth-Harville recursion that ICM software uses: P(1st) is proportional to chips, and each later place is found by removing a finisher and repeating. The difference is the input. Full ICM tools take every player's exact stack, while this calculator asks only for your stack, the total and the number of players, and assumes the other players share the remaining chips equally. That assumption is exact for your chance of finishing first and a reasonable approximation for the other places; it drifts when the other stacks are very uneven (for example one huge stack and several tiny ones). Chip-EV, by contrast, is simply your chip share × prize pool, which is only correct for winner-takes-all payouts.
What is a Nash push/fold range and how does ICM affect it?
A Nash equilibrium push/fold range is the set of hands you should go all-in with (or call all-ins with) such that neither you nor your opponents can improve their strategy by deviating. These ranges are computed by maximizing ICM equity rather than chip equity, which means they are tighter than pure chip-EV ranges near pay jumps. For example, you might fold A-Jo from the small blind under ICM pressure even though chip-EV says shove. ICM pressure is highest for medium stacks caught between large stacks who can bust them and short stacks approaching blinding out. The 'bubble factor' quantifies how much tighter ICM forces you to play relative to chip-EV: bubble factors near 1.5 are common on the money bubble, meaning you need 50% more equity to call than chip-EV would suggest.
What are common mistakes when applying ICM in tournaments?
Ignoring ICM completely in cash-game-style 'chip-EV' play near pay jumps is the most expensive mistake — many players burn buy-ins by calling all-ins that are chip-EV positive but ICM-EV negative. Using chip share × prize pool (chip-EV) instead of ICM near pay jumps misstates stack values by 5–15%, enough to flip close decisions. Applying ICM to deep-stack early levels wastes effort because ICM equity ≈ chip equity when no pay jumps loom. Forgetting that opponents' calling ranges also tighten under ICM means your shoves should widen against ICM-aware opponents (less called) but tighten against calling stations. Treating cash chops or final-table deals as if ICM equals dollar value ignores the negotiation premium big stacks typically command in chops. Finally, using ICM in non-tournament formats (cash games, heads-up SnGs) is mathematically meaningless.
When should I NOT use ICM calculations?
Cash games have no payout structure — every chip equals one dollar, so chip-EV and dollar-EV are identical and ICM is irrelevant. Winner-take-all tournaments are also a chip-EV exercise because there is only one prize and your equity scales linearly with chips. Early-stage MTTs with thousands of players remaining have such uniform payouts relative to stack size that ICM is approximately equal to chip-EV. Re-buy tournament periods reset the stack landscape on each rebuy, breaking the ICM assumption of fixed total chips. Final-table deals (chops) involve negotiation and intangible factors that pure ICM doesn't capture — many big stacks negotiate above their ICM equity, and short stacks below. Live tournaments with significant ICM impact also have meta-game factors (table image, physical reads, fatigue) that ICM-based solvers can't model.
