What is ICM?

The Independent Chip Model (ICM) is the standard way to convert poker tournament chip stacks into real-money equity. Unlike a cash game where a chip is worth its face value, tournament chips have diminishing dollar value: doubling your stack rarely doubles your prize-pool equity, because most of the money is concentrated near the top of the payout structure.

ICM treats the remaining tournament as a probabilistic finishing-order problem. The chance any player finishes first is proportional to their share of all remaining chips. Conditional on that finish, the chance of each other player finishing second is proportional to their share of the remaining chips — and so on down to the last paid position. Sum every (probability × prize) across positions and you get that player's dollar equity.

P(player wins) = stack / total chips  ·  P(2nd | someone wins) = stack / (total − winner's stack)

When ICM matters

• Final-table deals. The most common live use. When the remaining players want to chop the prize pool, ICM is the neutral baseline that everyone (chip leader, short stack, middle stacks) can agree is mathematically fair. Big stacks usually want to negotiate above the ICM number; short stacks at or above ICM.
• Bubble decisions. Near the money, short stacks fold premium hands they'd snap-call in a cash game because losing eliminates them before any prize, while folding lets them ladder up as other short stacks bust. ICM quantifies the cost of busting.
• Pay-jump pressure. Whenever a meaningful prize jump is one or two eliminations away, the player closest to busting plays tightest and the chip leader plays loosest (re-stealing pressure). ICM equity tells you exactly how big each pay jump actually is in dollars.
• Satellite play. Pure ICM is sharpest when the top X positions all win the same prize (a seat) and everyone else gets nothing — finishing first has the same value as finishing X-th, so the equity math is wildly different from a normal MTT.

How to read the results

For each player the calculator shows four numbers:

• Chips — the stack you entered, with its share of all remaining chips below.
• ICM equity — the dollar value of that stack right now, given the prize pool and structure. Players' ICM equities always sum to exactly the prize pool.
• Chip-EV — what the stack would be worth if every chip had equal cash value (stack / total chips × prize pool). This is what a beginner intuitively assumes.
• Δ (ICM − Chip-EV) — the gap. Positive Δ means ICM benefits this player vs the naive chip-share answer; negative Δ means ICM hurts them.

The classic ICM pattern: short stacks have positive Δ, the chip leader has negative Δ. A short stack only needs to outlast a couple of opponents to ladder up a pay jump; the chip leader can't physically win more than first place, so their excess chips above what they need to win are worth less per chip than the chips a short stack holds.

Using ICM for a final-table deal

The fairest baseline deal is: each player gets their current ICM equity in cash. Both sides usually adjust from there:

• Chip leader leverage. The big stack typically refuses pure ICM (since they have skill edge + the most chip equity already), and pushes for a deal closer to the chip-EV number, leaving 1st-place money on the table to play for.
• "Save deals." Each player locks in a minimum (often their ICM number rounded down), and the remainder is played out for an agreed top-end prize. Reduces variance for everyone without fully ending the tournament.
• ICM-plus-skill adjustment. Players who think they have a skill edge ask for 5–15% above their ICM. Players who admit they're outmatched at the table take 5–15% below in exchange for locking in the deal.

Limitations to remember

• No skill model. ICM assumes every chip plays the same regardless of who holds it. In reality a skilled player extracts more from their stack than an amateur does.
• No blind-level awareness. A short stack 3 BBs deep at the bubble is in much worse shape than a short stack 30 BBs deep. ICM treats both as the same chip count.
• Position blind. ICM doesn't know who's about to post the big blind or who has positional advantage post-flop.
• Calculation cost. Exact ICM is O(n!) — this calculator handles up to 10 players. For more players you'd want a Monte Carlo approximation.
