Illinois Medical Malpractice Settlement Calculator
Estimate a medical malpractice settlement under Illinois law. The calculator applies this jurisdiction's own comparative fault rule and damages ceilings, and every figure below is the one our verified data holds, with the statute behind it and the date we checked it.
What Illinois law does to your claim
Four things in state law shape a malpractice claim: how long you have to file, what must happen before you file, what happens if you were partly at fault, and whether the state puts a ceiling on what a jury can award. Here is what we hold for this one.
Illinois bars recovery if plaintiff is 51% or more at fault.

The Illinois General Assembly's statute site did not answer this session. So this page does not say whether Illinois requires a notice to the provider, an expert's affidavit or a review panel before a malpractice suit. That is a gap in our research, not a finding that nothing is required. Ask a licensed Illinois attorney before you file.
None on record means our verified data holds no figure of this kind for this state. It is not a finding that no limit could apply to your claim.
What partial fault costs you in Illinois
The same claim, fracture with surgery, several months of recovery, run through the calculator above four times, with nothing changed but the share of fault assigned to the claimant. The numbers are the engine's output, not an editorial claim about what these cases are worth.
One case, run through the calculator above four times with only the claimant's share of fault changed, under Illinois law. No coverage ceiling is applied, because we would be inventing the at-fault party's policy. These shares illustrate the rule; they are not an estimate of your own fault.
Every Illinois deadline we hold
A claim can be more than one kind of case, and the clock is different for each. These are the Illinois periods in our verified data, with the statute behind each one. A deadline is the outside limit, never a target, and other rules can shorten it.

Every count below is read from our state-law data across all 51 jurisdictions, so it moves when the data does. What you will not find here is an average settlement figure: the only one we could compute is a model, and a model presented as a measurement is not a fact.
- 24 of the 51 jurisdictions we track apply modified comparative negligence with a 51% bar, and Illinois is one of them.
- Its 2 years to file is the same as the most common deadline in the country, which 31 jurisdictions use. Across the 51 jurisdictions the deadline for this case type runs from 1 year to 4 years.
- We have read the official text of 26 jurisdictions' rules on what must come before a malpractice suit, and 25 of them require something: a notice to the provider, an expert's affidavit, certificate or opinion, or a review panel. We have not read Illinois's.
- 23 of the 51 jurisdictions limit medical malpractice non-economic damages in our data and Illinois is not among them, so an estimate here is not held down by a ceiling we hold.
Comparisons are drawn from the legal levers that actually move a case value, not from closed-case data, which we do not hold. See the full methodology
