Personal Injury Settlement Calculator

Introduction to multiplier-method injury settlement estimates

This personal injury settlement calculator builds a rough multiplier-method scenario out of the numbers you already have on paper: treatment bills, missed pay, repair invoices, an assumed fault share, and the liability limit on the other side's policy. It exists so you can see the arithmetic that sits underneath a negotiation, not so it can tell you what a claim is worth. Nothing on this page is legal advice, and settlement values vary enormously by jurisdiction, by insurer, and by the evidence in an individual file. For guidance about a specific claim, consult a licensed attorney in your state.

American injury claims are usually described in two buckets. Special damages are the losses that come with a receipt or a pay record, such as medical bills and lost earnings. General damages are the losses that do not, such as physical pain, emotional distress, and the loss of ordinary activities. Adjusters and plaintiff lawyers sometimes approximate general damages by multiplying a specials figure by a number between roughly 1 and 5. That shorthand is a negotiating convention, not a rule of law: no statute sets a multiplier, and no court is bound by one.

Because the convention is so widely repeated, it is worth understanding precisely. The calculator below implements it carefully, keeps property damage out of the multiplied base, and then applies the two adjustments that most often separate a headline number from an actual check: comparative fault and the policy limit.

How to use the injury settlement calculator

Fill in the amounts you can support with documents, choose the base and the multiplier deliberately, then read the breakdown rather than only the headline figure.

1. Medical expenses. Enter injury-related treatment billed to date: emergency care, imaging, physician visits, surgery, physical therapy, prescriptions, and durable equipment. Use billed amounts consistently, and note whether your state lets a claimant recover billed charges or only amounts actually paid.
2. Lost income. Enter earnings you missed because of the injury, supported by pay stubs, an employer letter, or, for self-employed claimants, tax records and invoices.
3. Property damage. Enter vehicle repair or total-loss value and any damaged belongings. This amount is added to the economic total but is deliberately excluded from the multiplied base.
4. Multiplier base. Choose whether the multiplier is applied to medical expenses alone, the most common convention, or to medical expenses plus lost income, which some practitioners prefer for claims where time off work is the main measure of disruption.
5. Pain and suffering multiplier. Pick a value that you could defend with records. A 4x multiplier on a soft-tissue strain that resolved in three weeks is not a defensible position.
6. Your comparative fault share. Optional. Enter the percentage of fault you expect to be assigned to yourself; leave it blank or at zero if fault is not contested.
7. Policy limit. Optional. Enter the at-fault party's per-person bodily injury limit if you know it. The result is capped at that number.
8. Attorney contingency fee. Optional. Enter the percentage in the fee agreement to see the amount remaining after the fee alone.

The settlement formula: special damages, multiplier, and general damages

The calculator separates economic damages from the multiplied base on purpose. Write for medical expenses, for lost income, for property damage, and for the multiplier. Economic damages, also called special damages, are the plain sum:

General damages are approximated by multiplying the selected base , which is either or , by the multiplier:

The gross claim value is the sum of the two:

This is the important correction over the cruder version of the formula, in which the whole economic total including property damage is multiplied. Multiplying a vehicle repair bill by a pain-and-suffering multiplier treats sheet metal as evidence of human suffering, which no adjuster will accept and which can inflate an estimate by many thousands of dollars.

Comparative fault, the policy limit, and the contingency fee

Two adjustments usually stand between the gross claim value and a real payment. If you bear a share of fault , expressed as a fraction, most states reduce recovery proportionally, and liability insurance pays no more than the applicable per-person limit :

Finally, a contingency fee at rate is taken from the recovery, leaving an amount before case costs and liens:

Comparative negligence rules differ. A pure comparative jurisdiction reduces recovery by the claimant's fault share no matter how large it is. Modified comparative jurisdictions bar recovery entirely once the claimant's share crosses 50 or 51 percent, and a small number of jurisdictions still apply contributory negligence, under which even a small share of fault can defeat the claim. The calculator performs the pure comparative arithmetic only; it does not know which rule your state uses.

Worked example: a rear-end collision with $9,400 in medical bills

Suppose an emergency-department visit, imaging, and twelve weeks of physical therapy total $9,400 in medical expenses. The claimant missed six weeks of work worth $4,200, and the vehicle repair came to $3,100. Economic damages are therefore $9,400 + $4,200 + $3,100 = $16,700.

The claimant selects medical expenses plus lost income as the base, so , and chooses a multiplier of 2.5 for a documented soft-tissue injury with a long course of therapy. General damages are $13,600 x 2.5 = $34,000, and the gross claim value is $16,700 + $34,000 = $50,700.

Now apply the adjustments. The insurer argues the claimant braked late and assigns a 20 percent fault share, reducing the figure to $50,700 x 0.80 = $40,560. The at-fault driver carries a $50,000 per-person limit, which does not bite here because $40,560 is below it. With a 33 percent contingency fee, the fee is $13,384.80 and the amount remaining before case costs and liens is $27,175.20.

Change one assumption and watch the estimate move. Using medical expenses only as the base gives general damages of $9,400 x 2.5 = $23,500 and a gross value of $40,200 rather than $50,700 — a difference of $10,500 that comes purely from a convention nobody has legislated. That sensitivity is the single most important thing to understand about the multiplier method.

Choosing a pain-and-suffering multiplier you can defend

The multiplier is the input with the largest proportional effect on the output, and it is the input with the least objective support. The bands below are illustrative descriptions of how the convention is usually discussed, not legal standards, and an adjuster is free to reject any of them.

Two files with identical bills can support very different multipliers. Consistent treatment, a clear causal chain from the incident to the diagnosis, and contemporaneous notes about daily limits push the defensible range up. A gap in treatment, a pre-existing condition affecting the same body part, or a disputed liability picture pushes it down, sometimes sharply.

What this injury settlement calculator includes and omits

The model is deliberately small. The table below shows exactly what it does and does not represent, so you can tell which parts of a real claim still need professional analysis.

Limitations and assumptions behind this settlement estimate

Read the result with these limitations and assumptions firmly in mind:

• The multiplier is an assumption, not a measurement. No statute, regulation, or court rule sets it. Two reasonable people can pick numbers a full point apart from the same medical chart.
• Inputs are taken at face value. The calculator does not test whether an expense is injury related, medically necessary, causally connected, or recoverable in your state.
• Jurisdiction is not modeled. Comparative negligence rules, non-economic damage caps, collateral source rules, no-fault thresholds, and filing deadlines all vary and none of them are applied here.
• Collectability is ignored. A judgment against an uninsured or insolvent defendant may recover nothing regardless of the number this page prints.
• Liens and case costs are excluded. Health insurers, Medicare, Medicaid, and medical providers may assert reimbursement rights that come out of the settlement before you see it.
• No legal relationship is created. Using this calculator is not legal advice and does not create an attorney-client relationship with anyone.

Do not accept or reject a settlement offer because it is above or below this calculator's output, particularly where injuries are serious, treatment is ongoing, or liability is contested.

When to talk with a personal injury lawyer

A lawyer can evaluate the facts this arithmetic cannot see: whether the treatment record supports causation, how a local jury has historically valued a similar injury, whether an additional defendant or policy is available, and how close the filing deadline is. Legal advice is especially worth seeking when:

• Injuries are severe, permanent, or still under active treatment.
• Medical bills and lost income are large relative to the known coverage.
• Fault is disputed, or more than one party or insurer may be responsible.
• An insurer denies the claim, delays, or offers an amount that does not match the documented losses.
• A statute of limitations may be approaching; missing it can end the claim entirely.

Many personal injury attorneys evaluate claims at no charge and work on contingency. If cost is a barrier, state and local legal aid organizations and bar association referral services can help you find representation.

The fault adjustment follows the pure form described at comparative negligence, and filing deadlines are summarized at statute of limitations. Liability limits are explained by the Insurance Information Institute in Auto insurance basics. If you need help finding counsel, see USA.gov legal aid. The multiplier itself is a negotiating convention with no statutory basis, which is why this page asks you to choose it.
