Personal Injury Compensation Calculator (UK)

This is the master personal injury compensation calculator covering all injury types — from minor soft-tissue injuries through to catastrophic brain and spinal injuries. The calculator uses the Judicial College Guidelines (18th edition) to estimate the general damages bracket for your injury, then adds any special damages (lost earnings, treatment costs, care) to give you a combined estimated range.

If you know what specific injury type you want to calculate for, the dedicated calculators for whiplash, back injury, broken bones, and so on may be more relevant. This master tool is best when you want a quick estimate without selecting a specific body part first, or when your injuries span multiple categories.

Estimate your compensation

Personal injury compensation calculator

Based on the Judicial College Guidelines, 18th edition (2026).

How This Calculator Works

You select the type of injury from the dropdown, then choose the severity that best matches your experience. The tool maps your selections to the relevant Judicial College bracket and shows three figures — the low, middle, and high points of that bracket. Selecting your recovery time refines the position within the bracket: shorter recoveries and fuller recoveries point towards the lower end, longer or permanent symptoms towards the upper end. The special damages section is optional but produces a more complete estimate.

Factors That Affect Your Personal Injury Claim

The figure the calculator produces is a starting point. Several factors push the actual settlement higher or lower:

  • Severity and permanence — permanent symptoms shift figures towards the top of the bracket
  • Impact on work — inability to return to your previous occupation substantially increases the claim
  • Impact on daily life — loss of hobbies, sports, family activities, and independence
  • Need for ongoing treatment — surgery, physiotherapy, psychological therapy
  • Care requirements — paid carers or family care valued at commercial rates
  • Equipment and adaptations — wheelchairs, prosthetics, home modifications
  • Pre-existing conditions — these can complicate causation but rarely defeat a claim
  • Contributory negligence — if you were partly at fault, your compensation is reduced by that percentage

What This Calculator Doesn’t Capture

The calculator does not account for: future medical complications, the psychological impact of the injury (sometimes a separate PTSD claim), interim payments already received, court costs, or the negotiating dynamic between your solicitor and the insurer. It also assumes liability is established — if liability is contested, the realistic settlement may be lower or the case may proceed to court.

Next Steps

If the calculator estimate suggests a worthwhile claim, the next step is to speak to a specialist personal injury solicitor. Most work on no win no fee arrangements, which means you pay nothing if the claim is unsuccessful and a capped percentage of compensation (maximum 25 per cent under the LASPO 2012 framework) if it succeeds. A specialist will give you a more precise figure after reviewing your medical records and the accident circumstances.

Common Questions

What are the Judicial College Guidelines?

The Judicial College Guidelines for the Assessment of General Damages in Personal Injury Cases (currently 18th edition, published April 2026) are the reference work used by judges, solicitors, and insurers across England and Wales to value personal injury claims. They set out compensation brackets for every category of injury, from minor soft tissue damage to catastrophic brain injury. Brackets reflect typical court awards and are updated every two to three years to reflect inflation and emerging case law.

How accurate is this calculator?

The calculator gives a directional estimate based on published guidelines. Actual settlements vary based on the specific facts of each case, the strength of evidence, the prognosis at the point of settlement, contributory negligence findings, and the negotiating position of the insurer. The figure should be treated as a starting point for understanding the range of possible outcomes — a specialist solicitor will give you a more precise figure after reviewing your medical evidence and circumstances.

What counts as special damages?

Special damages are the financial losses caused by your injury — lost earnings (past and future), medical and rehabilitation costs, care costs (whether paid carers or unpaid family care valued at commercial rates), travel to medical appointments, equipment and aids, and home or vehicle adaptations where needed. These are added to your general damages (pain, suffering, loss of amenity) to produce the total claim value.

Should I use this calculator or a specific injury calculator?

Use this master calculator for a quick overview or where you have multiple injuries. Use a dedicated calculator (whiplash, back injury, broken bone, etc) where you have a single specific injury — the dedicated calculators ask more relevant questions and produce a more refined estimate. Either way, the underlying JC Guidelines data is the same.

How long until I see the actual compensation?

Straightforward cases typically settle within 6-12 months. More complex cases, particularly those involving long-term prognosis assessments or contested liability, can take 2-3 years. Catastrophic injury cases sometimes take longer still because final settlement isn’t calculated until the full extent of lifetime impact is known.
