About this calculator
The Independent Chip Model (ICM) translates tournament chip counts into prize equity. Unlike chip-EV, ICM recognises that chips are not linearly valuable: doubling your stack does not double your prize equity when several places are paid. ICM Value = Σ P(finish in place k) × Payout(k). The finish probabilities follow the Malmuth-Harville method used by ICM software: P(1st) = yourChips / totalChips; for each later place, every possible higher finisher is removed and your share of the remaining chips is taken again. Payouts are the selected percentages of the prize pool for 1st, 2nd, 3rd and so on. Because only your own stack is entered, the other players are assumed to hold equal stacks; with very uneven stacks use full ICM software. ICM is below chip-EV for big stacks and above it for short stacks; with a winner-takes-all payout it equals chip share × prize pool.
How to use
Suppose you have 30,000 chips in a 3-player finish with 100,000 chips in play, a $1,000 prize pool and the top-heavy 65/25/10 structure ($650/$250/$100). The other two players are assumed to hold 35,000 each. P(1st) = 30,000 / 100,000 = 30% → 0.30 × $650 = $195. P(2nd) = 70% × 30,000 / (30,000 + 35,000) = 32.3% → 0.323 × $250 = $80.77. P(3rd) = 37.7% → 0.377 × $100 = $37.69. ICM value ≈ $313.46, slightly above your $300 chip equity because even third place is paid. With the default inputs (15,000 of 100,000 chips, 12 players, $10,000, top heavy) the ICM value is $1,446.73 against a $1,500 chip equity.
Frequently asked questions
Why is ICM important when making all-in decisions in poker tournaments?
ICM is critical because chips in a tournament do not have a fixed dollar value — losing all your chips means earning zero prize money, no matter how big your stack was. This creates a risk-aversion asymmetry: doubling up rarely doubles your ICM value, but busting always sets it to zero. Near the money bubble or at the final table, a call that is chip-EV positive can still be ICM-negative if the risk of elimination outweighs the chip gain. Understanding ICM helps you avoid costly all-in calls with marginal hands at high-pressure moments.
How does payout structure affect ICM calculations in a tournament?
The steeper and more top-heavy the payout structure, the more ICM rewards survival over chip accumulation. In a winner-take-all event, ICM collapses to chip equity since the only payout is first place. But in a typical tournament where 15–20% of players cash, avoiding elimination early can be worth more than winning a coin flip. Flat payout structures, by contrast, make aggressive chip accumulation more valuable since the monetary difference between finishing positions is smaller. Always input your tournament's exact payout ladder for the most accurate ICM valuation.
What is the difference between chip EV and ICM EV in tournament poker?
Chip EV (expected value) measures whether a decision gains or loses chips on average, treating each chip as equal in value. ICM EV accounts for the real monetary worth of those chips given the prize distribution and your current stack. A shove that gains 10,000 chips on average might be chip-EV positive but ICM-EV negative if it risks your entire stack in a spot where survival nets you a significant prize jump. Professional tournament players always think in ICM terms near the bubble and final table, using chip EV primarily in the early stages when ICM pressure is lower.
