Illinois Prejudgment Interest Rate in Personal Injury and Wrongful Death

In Illinois, prejudgment interest on damages in personal injury and wrongful death actions accrues at the rate set by statute. The governing authority, 815 ILCS 205/2, establishes that the interest rate is 5% per year. This interest begins to run from the date the action was filed, not from the date of the injury, and applies only to the amount of damages awarded at trial. The statute does not apply to every case; it sets out specific conditions and exceptions that determine when the right to interest attaches. The worked example below illustrates how the 5% rate is calculated over time. For an estimate tailored to your case, use the DocketMath calculator.
