Car Accident Settlement Calculator

How this calculator works — the multiplier method, step by step

There is no secret database of settlement values. What insurance adjusters actually do — and what this tool reproduces — is a two-part calculation:

1. Add up your special damages. These are the provable dollar losses: medical bills to date, reasonably expected future treatment, and income you lost while recovering. Property damage is tracked separately because it is usually paid on its own, without a pain multiplier.
2. Multiply by a severity factor (1.5–5) for pain and suffering. A soft-tissue injury with a full recovery sits at the bottom of the range. Surgery, permanent impairment, or disfigurement push the multiplier up. The result is added on top of your economic damages.

Worked example: $8,500 in medical bills, $2,000 in projected future treatment, and $3,200 in lost wages is $13,700 in special damages. At a ×2 multiplier (moderate injury, months of treatment), pain and suffering adds $27,400. With $6,000 in vehicle damage, the case totals roughly $47,100 — and the calculator shows a ±20% negotiation band around that midpoint, because that is realistically where offers and demands land.

For context on what documented losses look like nationally: the Insurance Information Institute reports the average bodily-injury liability claim reached $28,278 in 2024 (property damage: $6,770), and the National Safety Council estimates the average economic cost of a disabling-injury crash at about $174,000. Those are documented costs, not settlement promises — but they show why serious-injury claims are worth many times a minor one. We explain the full national picture in our average car accident settlement guide.

What actually moves your number

Two cases with identical medical bills can settle for very different amounts. These are the levers adjusters and lawyers actually argue about:

• Fault. Every state discounts your recovery by your share of blame — and some cut you off entirely past a threshold (see the state rules below).
• Policy limits. You generally cannot collect more than the at-fault driver's coverage plus your own underinsured-motorist coverage, no matter what a calculator says. This is why the first document a lawyer requests is the insurance declarations page.
• Documentation. Consistent treatment records, no gaps, and a clear diagnosis raise the credible multiplier. Missed appointments and late reporting lower it.
• Who is on the other side. Claims involving commercial vehicles carry higher policy limits and more negligence theories — a truck accident claim is a different animal from a fender bender.

State rules that change the math

The multiplier method is universal; the legal rules around it are not. In the states we cover in depth:

• Texas — modified comparative fault with a 51% bar (Tex. Civ. Prac. & Rem. Code § 33.001): if you are more than half at fault you recover nothing, and anything less reduces your award proportionally. Two-year filing deadline (§ 16.003).
• Georgia — modified comparative fault with a 50% bar (O.C.G.A. § 51-12-33) and a two-year deadline (§ 9-3-33). Claims against government entities carry short ante litem notice windows.
• Arizona — pure comparative fault (A.R.S. § 12-2505): you can recover even if you were 90% at fault, reduced by your percentage. Two-year deadline (§ 12-542).
• Florida — no-fault state: your own PIP pays first regardless of fault, and you must cross the serious-injury threshold (Fla. Stat. § 627.737(2)) to claim pain and suffering from the at-fault driver. Since HB 837 (2023), being over 50% at fault bars recovery, and the deadline is two years (§ 95.11(5)(a)).

From estimate to money in hand

The calculator's range is a gross number. Before comparing offers, understand what comes out of a settlement: attorney fees (typically 33–40% on contingency — Florida caps them on a sliding scale under Bar Rule 4-1.5(f)(4)(B)), case costs, and repayment of medical liens. Our guides walk through the rest of the journey: how long a settlement takes, whether your settlement is taxable, and how injury type drives documented costs.
