Whiplash Settlement Calculator, from your losses, your share of fault and your state's rules.
Estimate a whiplash settlement after a car crash, see whether your state's no-fault rules limit a pain and suffering claim, and read your filing deadline.
How whiplash settlements are calculated
This calculator adds up the losses you enter, multiplies the injury losses for pain and suffering, and then applies your share of fault, your state's rules and any policy limit you give it. Here's what each step actually does to your number.
What the formula returns at these inputs
These are outputs of the calculator on this page, not settlements anyone received. Each row feeds the inputs described into the same formula the calculator runs, and the last column is the number it returns. We hold no dataset of closed cases, so we publish the formula working instead of figures we cannot source.
Every row is run in Arizona with no share of fault assigned to the claimant. No coverage ceiling is applied, because we would be inventing the at-fault party's policy. Arizona is used because our state-law data records it as a pure comparative fault jurisdiction with no damages cap of any kind, so nothing here is clipped by a state limit and you can see the formula itself. Pick your own state in the calculator above and the number moves. Economic damages include property damage, which the formula adds to the total but never multiplies.
What whiplash is
MedlinePlus, the National Library of Medicine's health site, names the injury plainly.
“Whiplash, a soft tissue injury to the neck, is also called neck sprain or strain.” (MedlinePlus, Neck Injuries and Disorders (Last updated August 4, 2026)) The name comes from the motion: in a crash, the head can be thrown one way and snapped back the other, and the neck takes the strain.
On care, the same page says: “Treatment depends on the cause, but may include applying ice, taking pain relievers, getting physical therapy or wearing a cervical collar.” (MedlinePlus, Neck Injuries and Disorders (Last updated August 4, 2026))
Pain and stiffness can take time to show after a crash, and the injury is not seen on a photograph of a car. That is why a whiplash claim leans on the medical record: what was reported, when, and what treatment followed.
This page is for whiplash from a crash. If the injury came from a fall, a sport or another accident, the pain and suffering calculator on this site fits better, because it uses the general injury period and not the motor-vehicle rules.
Whiplash and no-fault insurance
In a no-fault state, whether you can sue the other driver for pain and suffering can turn on the injury itself.
A no-fault state limits a suit for pain and suffering against the at-fault driver unless the injury meets a threshold the state sets, or lets a policy election decide it. In thirteen jurisdictions the calculator prints that line beside its figure, read from the state's own law, with a link to where the car accident page quotes the threshold's words.
A soft-tissue injury may or may not meet a state's threshold, and the calculator cannot know which side yours falls on, so it does not change the figure. It says, next to the figure, that the figure is one you may not be able to sue for, and why.
Your own policy can pay some costs first under a no-fault system, whatever the threshold says about a suit. The car accident page on this site quotes each state's rule on personal injury protection and medical payments coverage.
How the whiplash settlement estimate is built
The calculator prices the claim from your figures and starts on the soft-tissue injury type, which you can change.
Enter the medical costs, the pay lost, and the damage to your vehicle, then the severity, the length of recovery and your share of fault. The pain-and-suffering factor runs from 1.0x to 5.0x, and the injury type adjusts it.
The calculator also asks for the at-fault driver's policy limit, because a claim against a driver is paid within the coverage that driver carries. Where your state has rules on uninsured drivers, the result prints them beside the figure.
Then it takes out a contingency fee, case costs and medical liens at fixed rates, which are stand-ins and not what your lawyer will charge. The result is a range from your own figures, not a promise of what an insurer will pay.
Documenting a whiplash injury
A whiplash claim is built on records made at the time.
Get checked after a crash, even if the pain seems minor at first, and tell the doctor about every symptom: neck pain and stiffness, headaches, pain into the shoulders or arms, dizziness, trouble sleeping. Ask for copies of the records, the imaging reports and the bills.
Follow the treatment plan, and keep every appointment you can. If you miss one, write down why. Keep a short daily record of pain, of what you could not do, and of the work you missed.
Photograph both vehicles and the scene, keep the police report and the repair estimates, and write down the names of witnesses.
Talking to the insurer about a whiplash claim
What you say early can follow the claim to the end.
You can be asked for a recorded statement by the other driver's insurer. You can ask what it will be used for, decline until you have your records together, or ask a lawyer first. Describe the facts of the crash, and do not guess about your injury or say you are fine before a doctor has seen you.
An insurer can ask you to sign an authorization for your medical records. Read what it covers: an authorization limited to the crash and the injury is different from one that reaches every record of your life.
An early offer can come before the injury has settled down. Before you accept one, compare it with the costs so far and the treatment still ahead, which is what the calculator adds up.
When the clock starts on a whiplash claim
The filing period is the one your state sets for a motor-vehicle injury claim, as on the car accident page.
The calculator counts from the date of the crash and shows the period for a car accident claim in the state you pick, with the disclosures that go with it where a state's motor-vehicle provision sets its own period.
A no-fault state can also set deadlines for a claim on your own policy, and those can be much shorter than the period to sue. Read your policy and report the crash to your insurer promptly.
If the injury did not come from a crash, the motor-vehicle rules do not apply, and the pain and suffering calculator on this site shows the general period.
Before you settle a whiplash claim
This site is not a law firm, does not refer anyone to a lawyer, and cannot say what a lawyer would recover.
A settlement is final. Before you sign a release, make sure the treatment has run its course or that the costs still ahead are in the figure, and check whether a no-fault threshold limits the claim in your state.
A lawyer who handles car accident claims in your state can say whether your injury meets the state's threshold, what the other driver's coverage is, and whether the offer reflects the claim. Bring your records, your daily notes, the police report, the insurers' letters, and the figure this calculator shows.
What actually moves your settlement
Two cases with the same medical bills can settle for very different amounts. These are the variables that pull them apart.
Whiplash settlement: filing deadlines by state
Once this deadline passes, your case is gone, regardless of how strong it was. The calculator counts each period from the date of the incident, and a lawyer in your state can confirm when yours began.
