ICM Calculator

In cash games, chips equal dollars. Double your stack, double your money. Tournaments break that relationship. The moment you enter an MTT, the connection between your chip count and your share of the prize pool becomes non-linear. A player holding 50% of the chips at a three-handed final table is the favorite to win, but their equity in the prize pool is not 50%. It is less, because the other two players still have non-zero probabilities of finishing in every remaining position.

The Independent Chip Model is the math that accounts for this. ICM takes a set of stack sizes and a payout structure, calculates the probability of each player finishing in each position, and converts those probabilities into dollar equity. The output tells you what each seat is worth right now, regardless of what happens next. Every additional chip you accumulate is worth slightly less than the one before it, and every chip you lose costs slightly more than you gained from the last one you won.

That asymmetry affects every decision at a final table: whether to call an all-in, whether to accept a deal, and how aggressively to play near a pay jump. The calculator below lets you see it for yourself. For a deeper look at the math behind the model, including the Malmuth-Harville method and a worked example, see the full ICM theory lesson.

Three Ways to Split a Prize Pool

ICM chop distributes money according to each player's ICM equity. It accounts for the diminishing marginal value of chips and generally favors shorter stacks, whose chips are worth proportionally more per unit.

Chip chop guarantees every player the last-place prize, then divides the remaining pool by chip count. If you hold 40% of the chips, you get 40% of the excess above the minimum payout. This overpays the chip leader because going from 40% to 80% of chips does not double your expected payout.

Hybrid deals blend ICM and chip chop at a negotiated ratio. The slider in the calculator above models any blend. Hybrids are the most common in practice because they represent the middle ground between what the math says and what the big stack is willing to accept.

When to Accept a Deal

• You are a shorter stack near a significant pay jump
• Remaining players are similarly skilled, reducing any edge from playing on
• Fatigue is a factor and your hourly rate from continued play does not justify the risk

When to Play It Out

• You have a meaningful skill edge over the remaining field
• Pay jumps are not severe relative to your stack
• You are the chip leader and the ICM deal undervalues your position

The practical test: calculate your ICM equity above, then ask whether your expected hourly rate from continued play exceeds the guaranteed deal amount divided by expected hours of remaining play. If you cannot confidently answer yes, the deal is the better choice.

Reserving a portion of the prize pool for the eventual winner (the "money on table" option) keeps the game competitive after a deal. Most agreements leave 5% to 15% of first-place money on the table to keep everyone playing their best.

But deal-making only answers one question: what is your seat worth if everyone agrees to stop? It does not tell you whether to call the chip leader's shove or fold into a pay jump. That decision depends on the bubble factor: the ratio of how much you stand to lose by busting to how much you stand to gain by doubling up.

You are fourth of six at a final table. The deal calculator says your seat is worth $12,400. The chip leader open-shoves from the button. You look down at ace-king. In a cash game this is a snap call. At this final table, it might be a fold.

Bubble factor quantifies why. It measures the ratio between the equity you lose if you bust and the equity you gain if you double up. If your bubble factor against the chip leader is 2.0, you need 67% equity in the hand to justify calling, not 50%. The higher the bubble factor, the tighter your calling range needs to be, because the penalty for elimination outweighs the reward for accumulation.

The heat map below calculates the bubble factor for every possible confrontation at your table. Enter the same stacks and payouts, and see exactly where the pressure is highest.

Everything above assumes a graduated payout structure: first place gets more than second, second gets more than third, and so on. Satellites break that assumption. When four players win identical $10,000 seats, finishing first pays the same as finishing fourth, and the only boundary that matters is whether you win a seat or bust short of one.

This changes the math in ways that standard ICM cannot capture. In a regular tournament, doubling your stack always increases your equity. In a satellite with 5 players and 4 seats, a short stack with 5% of the chips might already have 40% equity, because folding into a seat is more likely than busting out. Accumulating more chips above the survival threshold adds almost nothing. Losing chips below it is catastrophic.

The calculator below uses a satellite-specific ICM model that accounts for equal payouts. Enter your satellite structure and see how equity distribution differs from what the standard model would predict.

ICM equity tells you what your seat is worth. Bubble factor measures what it costs to risk that seat. Satellite ICM covers the cases where the standard model no longer applies. Together, these three calculations cover the full range of tournament decisions: negotiating deals, calling all-ins, and adjusting your strategy when the payout structure flattens.

None of these tools account for skill edges, positional advantages, or blind level dynamics. They are mathematical baselines, not substitutes for judgment. The value is in knowing where the math puts you before you decide whether to deviate from it.
