Car Accident Settlement Calculator

Every serious settlement estimate splits your claim into two buckets.

Economic damages are the costs you can document: medical bills, future medical care, lost wages, lost earning capacity, and out-of-pocket costs like prescriptions and mileage to appointments. These get added up, not estimated.

Non-economic damages (pain and suffering) don't come with a receipt, so the industry prices them as a multiple of your medical bills: roughly 1.5x to 2.5x for minor soft-tissue injuries, 2.5x to 3.5x for moderate injuries such as fractures or a herniated disc, and 3.5x to 5x or more for surgical, catastrophic, or permanent injuries.

The formula:

(Medical bills x multiplier) + lost wages x (1 - your fault share) = estimated settlement range

Three honest caveats.

1. The multiplier is a negotiating convention, not a law. Insurer valuation software weighs specific diagnoses, treatment types, and durations, and an adjuster can land below 1.5x on a claim with treatment gaps, regardless of what this formula says.
2. The formula can't see your policy limits. A $150,000 claim against a driver carrying a $25,000 minimum policy and no other assets usually settles for $25,000, unless your own underinsured motorist coverage fills the gap.
3. Fault rules differ by state. In pure comparative states your recovery shrinks by your fault percentage at any level. In modified comparative states it disappears entirely at a 50% or 51% threshold. In the small number of contributory negligence jurisdictions, even 1% fault can bar recovery outright.

A driver is rear-ended at a red light. She goes to the ER, gets X-rays, and is diagnosed with whiplash requiring eight weeks of physical therapy. Medical bills total $8,600. She misses two weeks of work at $950 per week, $1,900 in lost wages. The other driver is entirely at fault.

Now change one fact. If the insurer successfully argues she was 15% at fault for a delayed brake response, the range drops to roughly $19,900 to $23,500. If her whiplash instead required a cervical fusion, the injury moves into the severe tier and the range roughly triples. If the at-fault driver carried only a 25/50 minimum policy, her realistic recovery from that driver caps at $25,000, with any remainder turning to her own underinsured motorist coverage.

No government or insurance-industry primary source publishes settlement averages broken out by specific injury type. The table below shows how the multiplier method scales with severity; treat it as a framework, not a data-backed prediction.

It can: show you the same multiplier logic an adjuster uses, so you can judge whether an offer you've received is in a reasonable range. It can also flag the two things that most reduce a claim: a low fault share working against you, and a fault percentage high enough to trigger your state's bar rule.

It cannot: see your state's specific fault rule, your policy limits, the quality of your medical documentation, or how a specific insurer's internal claims software (tools like Colossus and its successors) will actually price your file. It also cannot predict litigation outcomes, and it isn't a substitute for reviewing your policy or your medical records with a professional.

This calculator is state-neutral by design, but four state-level rules sit on top of the formula and can swing the outcome more than the multiplier does.

Fault rule. Pure comparative states reduce your recovery by your exact fault percentage, at any level. Modified comparative states apply a hard bar, commonly at 50% or 51% fault, past which you recover nothing. A small number of contributory negligence states can bar recovery entirely at even 1% fault.

No-fault / PIP systems. Several states require your own insurer to pay your medical bills and lost wages first, regardless of fault, and restrict when you can sue for pain and suffering, typically until your injury crosses a state-defined severity threshold.

Statute of limitations. Every state sets a deadline to file a lawsuit if a claim doesn't settle. Deadlines vary meaningfully by state and by whether the case involves a government vehicle, so confirm your state's specific deadline before you assume you have time.

Damage caps. A handful of states cap non-economic damages in certain case types, which can override what the multiplier formula would otherwise produce.

We deliberately don't publish per-state numbers on this page, because a wrong deadline or a stale fault-rule figure on a page like this is a real harm, not just an inconvenience. Confirm your state's specific rules against a current primary source before relying on them.

The honest answer depends on where your claim falls.

Likely fine on your own: a minor injury, clear liability, finished treatment, and bills under roughly $10,000. Document everything, negotiate in writing, and use the range above to judge any offer.

Worth a consultation: treatment is ongoing, an insurer disputes your injury or a pre-existing condition, your damages may exceed the at-fault driver's policy limits, or a surgical recommendation is on the table. Most personal injury attorneys offer a free initial consultation and work on contingency, meaning no upfront fee, so the cost of finding out where you stand is usually your time, not your money.

The first month after a crash is when most of a claim's value gets protected or lost, well before any real negotiation starts.

1. Get the crash report number at the scene and photograph vehicles, positions, signals, and visible injuries.
2. See a doctor the same day, even if you feel fine. Delayed symptoms are common, not the exception.
3. Notify your own insurer promptly, since your UM/UIM and PIP rights can depend on timing, but avoid giving the other driver's insurer a recorded statement.
4. Keep every bill, explanation of benefits, pay stub, and mileage log. The economic half of your claim is built entirely from paper.
5. Run your numbers here before an adjuster gives you theirs.
6. Don't settle until treatment ends or a physician can estimate future care. You settle once, and you can't reopen the claim after you sign.

This calculator applies the industry multiplier method using the severity bands published across this site: 1.5x-2.5x for minor injuries, 2.5x-3.5x for moderate injuries, and 3.5x-5x for serious or permanent injuries, with lost wages added at face value and fault applied as a straight percentage reduction. This is a widely used industry convention for framing a claim's likely range, not a formula fixed by statute or backed by a single published dataset, and we say so throughout this page rather than presenting it as more precise than it is.
