Personal Injury Compensation Calculator (UK)

UK personal injury compensation is made up of general damages for the injury itself and special damages for your financial losses. Road traffic whiplash lasting up to two years uses a fixed legal tariff; other injuries are valued using the Judicial College Guidelines.

Calculator

What do you want to estimate?

Your accident and injury

Used for your 3-year time limit.

Choose the most serious injury. Awards for several injuries are not simply added together.

How serious is it?

From a medical report, offer or solicitor. Replaces the bracket above.

Changes the small claims limit. Neck and back injuries lasting up to 2 years use the whiplash calculator.

Your financial losses (special damages)

After tax, up to today.

Including unpaid help from family.

Trips to appointments, parking.

Private physio, prescriptions.

Damaged clothing, equipment.

Blame

For example 25% if not wearing a seatbelt made the injury worse.

This is an estimate, not legal advice. Real outcomes depend on evidence, fault, insurance and negotiation. Most claims must start within 3 years, so speak to a solicitor before relying on it.

How we calculate (v1.2.0)

At a glance

  • Whiplash tariff increased for accidents from 31 May 2025.
  • Judicial College Guidelines 18th edition published 9 April 2026.
  • Time limit is usually 3 years.
  • No win no fee success fees are capped at 25% of damages (excluding future losses).

General damages and special damages

General damagesPain, suffering and loss of amenityWhiplash tariff (road traffic, up to 2 years) or Judicial College Guidelines
Special damagesLost earnings, care, travel, treatment, other costsActual losses, supported by receipts and payslips

Worked example

A hypothetical driver injured in June 2025 has whiplash expected to last seven months (tariff: £965), loses £900 in earnings, pays £240 for private physiotherapy, £60 in travel and receives £150 of care from family. A court finds them 15% to blame for not wearing a seatbelt properly.

General damages after 15% reduction£820
Special damages after 15% reduction£1,148
Estimated total£1,968

Because the injury damages are under £5,000, this road traffic claim would normally go through the small claims track using the Official Injury Claim portal.

Compensation brackets for common injuries

For injuries outside the whiplash tariff, general damages come from the Judicial College Guidelines, 18th edition (April 2026). The table summarises the brackets the calculator uses. Awards within a bracket depend on the medical evidence, and financial losses are added on top.

Figures last checked 29 September 2026. Severe brain, spinal and multiple injuries are outside the scope of this calculator and need specialist advice. See also back injury compensation and special damages you can claim.

How a claim usually works

  1. Medical evidence: An independent medical report confirms the injury and prognosis.
  2. Letter of claim: The other side (usually their insurer) is told about the claim under the pre-action protocol.
  3. Liability decision: The insurer admits or denies fault, sometimes partly.
  4. Valuation and negotiation: Offers are exchanged based on the medical evidence and your losses.
  5. Court proceedings: Only if the claim does not settle, and they must be issued within the time limit.

Evidence you will need

  • Medical records and an independent medical report on your injury and recovery.
  • Photos of the scene and your injuries, and details of any witnesses.
  • Accident report forms (for example, the accident book at work) and any police reference.
  • Payslips, receipts and a simple record of travel and care provided by family.

Interim payments

If the other side has admitted fault but the claim is not yet settled, you can ask for an interim payment: part of your compensation paid early to cover costs such as lost earnings, care or private treatment.

Claiming for a child

A parent or guardian can bring a claim on a child's behalf as their "litigation friend". Any settlement for a child must be approved by a court, and the money is normally held until the child turns 18. Children have until their 21st birthday to claim themselves.

Assault and violent crime

If you were injured in a violent crime, you may be able to apply to the Criminal Injuries Compensation Authority (CICA), a government scheme with its own tariff of awards and a general 2-year time limit from the date of the incident. It works differently from the claims covered by this calculator.

Contributory negligence: when you were partly to blame

Compensation can be reduced by the percentage of blame the court gives you. A well-known example is not wearing a seatbelt: under the Court of Appeal's guidance in Froom v Butcher, the reduction is typically 25% if a seatbelt would have prevented the injury altogether, 15% if it would have made it less severe, and nothing if it would have made no difference.

Small claims and the Official Injury Claim portal

Road traffic injury claims where the injury damages are £5,000 or less usually go through the small claims track, often using the Official Injury Claim portal. For other injury claims the small claims limit is £1,000. In the small claims track you generally cannot recover your legal costs from the other side.

No win no fee

Most injury solicitors work under a conditional fee agreement. If the claim succeeds, the success fee taken from your compensation is capped at 25% of damages for pain, suffering and past losses. You may also pay for after-the-event insurance. Always ask for the exact percentage in writing before signing.

Scotland and Northern Ireland

This calculator applies the law of England and Wales. Scotland and Northern Ireland have separate courts and rules. The whiplash tariff, for example, does not apply there.

Frequently asked questions

How is personal injury compensation calculated in the UK?

Compensation has two parts. General damages cover pain, suffering and loss of amenity, and are based on the Judicial College Guidelines or, for road traffic whiplash, a fixed legal tariff. Special damages cover financial losses such as lost earnings, care and travel. The total can be reduced if you were partly to blame.

What is the whiplash tariff?

For road traffic accidents in England and Wales, whiplash injuries lasting up to two years are compensated using fixed amounts set in law. For accidents on or after 31 May 2025 the amounts range from £275 (up to 3 months) to £4,830 (18 to 24 months), slightly higher if you also have a minor psychological injury.

How long do I have to make a claim?

Usually 3 years from the date of the accident or from when you first knew the injury was linked to it. For children, the 3 years start on their 18th birthday. Different rules can apply to some claims.

What does contributory negligence mean?

If you were partly responsible, for example by not wearing a seatbelt, your compensation can be reduced by a percentage that reflects your share of blame.

How much does a no win no fee solicitor take?

In personal injury cases the success fee a solicitor can take from your compensation is capped by law at 25% of your damages for pain, suffering and past losses (future losses are excluded). Many firms charge less, so ask for the percentage in writing.
