How car accident settlements are calculated
Settlements can feel like a black box, but adjusters and attorneys follow a fairly consistent formula. Here is the same logic our settlement calculator uses, explained step by step.
Step 1 — Add up your economic damages
Economic damages (also called "special damages") are the losses you can prove with paperwork. They include:
- Medical expenses — ambulance, emergency room, hospital stays, surgery, imaging, prescriptions, physical therapy, and follow-up visits.
- Future medical costs — ongoing treatment your doctor expects, such as additional surgery or long-term rehabilitation.
- Lost wages — income you missed while you were unable to work.
- Loss of earning capacity — if your injury permanently limits the work you can do.
- Property damage — vehicle repair or replacement and other damaged belongings.
Because these come with bills, pay stubs and estimates, they are the least disputed part of a claim and form its foundation.
Step 2 — Estimate non-economic damages
Non-economic damages ("general damages") compensate for intangible harm: physical pain, emotional distress, anxiety, loss of enjoyment of life, and disfigurement. Because there is no invoice for suffering, adjusters typically rely on one of two methods:
- The multiplier method — multiply your injury-related economic damages by a factor from about 1.5 to 5, depending on severity. This is the most common approach and the one our calculator uses. Read more on the pain and suffering multiplier page.
- The per diem method — assign a daily dollar amount to your suffering and multiply it by the number of days you are affected.
Step 3 — Apply comparative fault
If you were partly responsible for the crash, most states reduce your recovery under comparative negligence rules. The three main systems are:
| Rule | What it means |
|---|---|
| Pure comparative | You can recover even if 99% at fault, minus your share. |
| Modified (50% bar) | You recover only if you are less than 50% at fault. |
| Modified (51% bar) | You recover only if you are 50% or less at fault. |
A handful of states still use strict "contributory negligence," where even 1% of fault can bar recovery. Your state's rule can dramatically change the outcome.
Step 4 — Check the policy limits
A settlement is only as large as the money available to pay it. If the at-fault driver carries a policy that caps bodily injury coverage at, say, $50,000, that limit often becomes the practical ceiling — unless the driver has significant personal assets or you have underinsured motorist coverage of your own.
Step 5 — Negotiate
The first offer from an insurer is rarely the final number. Documentation, medical records, consistency, and persistence all influence where a claim lands. Serious or disputed cases are where a personal injury attorney most often adds value.
