Car Accident Settlement Calculator

Car accident settlements are typically calculated using the multiplier method: Total Settlement = (Medical Bills + Lost Wages) x Severity Multiplier. The multiplier ranges from 1.5x for minor injuries to 7x or more for catastrophic injuries. This calculator uses real medical cost data from CMS Medicare fee schedules to estimate the medical bill component.

Average car accident settlements vary widely by injury type. Whiplash averages $18,950, concussions average $25,000, and traumatic brain injuries can settle for $500,000 or more. With attorney representation, the average settlement is $77,600 compared to $17,600 without an attorney (Insurance Research Council 2025).

The pain and suffering multiplier is a number (typically 1.5 to 7) that insurance companies multiply your economic damages by to calculate non-economic damages. Mild injuries use a 1.5-2x multiplier, moderate injuries 2-3x, severe injuries 3-5x, and catastrophic injuries 5-7x or higher.

According to the Insurance Research Council (2025), claimants with attorney representation receive an average of $77,600 vs $17,600 without an attorney — 4.4x more. Most personal injury attorneys work on contingency (no upfront cost), making legal representation financially accessible for most injury victims.

Most car accident claims settle within 6-18 months. Minor injury claims may settle in 3-6 months. Claims involving surgery, permanent injuries, or disputed liability may take 1-3 years. It's generally advisable to reach maximum medical improvement (MMI) before settling to ensure all medical costs are accounted for.
