Personal injury settlements aren’t calculated using a formula. They are the product of a documented assessment of every category of loss a person has suffered, adjusted for risk factors, and then negotiated under a structured pre-court or court process. This article explains what goes into that assessment, how each component is valued, and what causes the final figure to be higher or lower.
The Framework: How Queensland Law Approaches Damages
Compensation in personal injury claims is assessed under the Civil Liability Act 2003 (QLD), which sets out the principles governing damages across public liability and common law claims generally. Separate legislative frameworks apply to WorkCover claims under the Workers’ Compensation and Rehabilitation Act 2003 (QLD), and to compulsory third party motor vehicle claims under the Motor Accident Insurance Act 1994 (QLD). The underlying principle across all of them is the same: compensation should, as much as possible, restore the claimant to the position they would have been in if the injury hadn’t occurred.
The Civil Liability Act divides damages into economic loss (loss of earnings, medical costs etc) and non-economic loss (pain and suffering). Both categories of damages are assessed separately, then combined to arrive at an overall value for the claim. Each type of loss is also subject to its own limits and thresholds under the Act.
| THE COMPENSATORY PRINCIPLE |
|---|
| The goal of personal injury damages is to make people whole again, not to penalise the at-fault party. Under Queensland law, damages aren’t awarded as punishment against the defendant. They’re awarded to reimburse the injured party for losses incurred as a result of the accident. This means that the monetary value of the claim is tied directly to evidence of actual losses suffered: medical records, proof of lost earnings, expert reports, and so on. An objectively serious injury that hasn’t been documented very well will support a much weaker claim than the same injury with excellent paperwork. |
The Heads of Damage: What Can Be Claimed
Each compensable category of loss in a personal injury claim is called a head of damage. Courts and insurers assess each head separately, using evidence specific to that head. The heads available depend on the type of claim and the applicable legislative framework.
Economic Loss
- Past Lost Income: Income already lost between the date of injury and the date of settlement. Calculated using evidence of the claimant’s pre-injury earnings: payslips, tax returns, and employment records. Periods of total incapacity are assessed separately from partial incapacity. The income loss is calculated net of tax, because the claimant would have paid tax on those earnings. Superannuation contributions lost during incapacity are accounted for separately.
- Future Loss of Earning Capacity: The injury’s effect on claimant’s capacity to earn income into the future. Unlike past lost income, loss of earning capacity considers how much a person would be able to earn after settlement, rather than how much they were earning before the accident. Calculated from date of settlement to expected end of working life. Estimated by calculating claimant’s likely lifetime earnings without the injury, then subtracting their projected earning capacity with the injury, and discounting the resulting stream of losses to present value (i.e. as a lump sum). Future loss of earning capacity claims are usually supported by vocational and economic expert evidence.
- Past Medical Expenses: All reasonable medical, hospital, pharmaceutical, physiotherapy, psychology, and allied health costs incurred from the date of injury to settlement. Includes costs already paid and any outstanding accounts. Where Medicare or private health insurance have contributed to treatment costs, those recoveries are accounted for in the calculation.
- Future Medical Expenses: Projected costs of medical treatment the claimant will require in the future as a result of the injury. Based on medical evidence about what treatment (if any) the claimant will need in the future. Discounted to present value using the prescribed discount rate.
- Care and Assistance: Costs of care required as a result of the injury. Covers both professional care services and care provided without charge by family members or friends (called gratuitous care). Gratuitous care is calculated at a rate prescribed under the Civil Liability Act 2003 (QLD), subject to a minimum threshold of hours per week before it becomes compensable. Evidence of the claimant’s functional limitations and records of care provided are required. Care and Assistance is generally not allowed in claims against WorkCover.
- Home Modifications: Costs of modifying the claimant’s home to accommodate a permanent disability. Relevant where the injury has caused lasting mobility impairment or other functional limitations requiring structural changes to the home. Supported by occupational therapy assessments and contractor quotes.
- Out-of-Pocket Expenses: Any other expenses incurred by the claimant because of the accident. Travel expenses to attend medical appointments; aids and equipment; over-the-counter medication costs; and other similar expenses that can be documented with receipts or reasonable estimates.
Non-economic loss: pain and suffering
In Queensland, compensation for pain, suffering and loss of enjoyment of life is usually referred to as general damages. This is the part of a personal injury claim that compensates an injured person for the physical pain, psychological impact, loss of amenity and reduced quality of life caused by the injury. It is assessed separately from economic losses, such as lost income, treatment expenses and care.
For most Queensland personal injury claims, general damages are assessed by reference to an Injury Scale Value, or ISV. The ISV system is set out in the relevant Queensland legislation and regulations. An injury is matched to a category in the ISV tables, and then given a numerical value that reflects the seriousness of the injury and its impact on the injured person’s life.
The ISV is not simply a medical percentage. It is a legal assessment that takes into account matters such as the nature and severity of the injury, the extent of pain and suffering, any permanent impairment, the effect on work and daily activities, treatment required, prognosis, and the way the injury has affected the person’s enjoyment of life. More serious injuries attract a higher ISV.
Once the appropriate ISV is assessed, the dollar value of general damages is calculated by reference to the applicable statutory table or indexation notice. This means that general damages in many Queensland claims are not calculated in the same open-ended way as some other heads of damage. The amount depends heavily on the injury category, the ISV range, and the evidence about how the injury has affected the claimant.
| HOW NON-ECONOMIC LOSS IS ASSESSED IN PRACTICE |
|---|
| Medical evidence from a specialist, addressing the functional and lifestyle impact of the injury, is the foundation of any non-economic loss claim. The assessment looks at pre-injury compared to post-injury life: activities no longer possible, relationships affected, sleep disruption and pain levels, and psychological impact. Insurers obtain their own medical opinion. The gap between the parties’ assessments of non-economic loss is often a significant negotiation point at the compulsory conference. |
Present Value: How Future Losses Are Discounted
Compensation for future losses is expressed in present terms. This means that instead of adding up all the years of lost income as a big dollar figure, it is discounted back to what it would be worth in a lump sum today. Essentially, if the claimant receives a lump sum payment now (and invests it sensibly), it should grow to equal the amount of the future losses over time. Think of it like the insurance companies are giving you the interest you’d lose if they paid out over time, as a lump sum.
The discount rate applied to future losses in Queensland is set out in the Civil Liability Act 2003 (QLD).
WORKED EXAMPLE | How present value discounting works
Hypothetical scenario (illustrative only. Not a prediction of any specific outcome.)
- Claimant is 35 years old. Pre-injury income: $80,000 per year after tax.
- Post-injury earning capacity: $40,000 per year.
- Annual income difference: $40,000.
- Estimated remaining working life: 30 years.
Raw sum over 30 years: $40,000 x 30 = $1,200,000
After applying the prescribed discount rate, the present value lump sum is substantially less than $1,200,000, because the claimant receives the money now rather than spread across 30 future years.
The calculation looks like this: $769.23 (weekly loss) x 30 year 5% discount multiplier (822) = $632,307.69
The exact present value depends on the rate in force at the time of settlement.
An actuary or economist calculates the figure using standard discount tables.
WHY PRESENT VALUE MATTERS
A small change in the prescribed discount rate, or the estimated future income figure, or the assumed retirement age produces a big change in the present value of future loss.
All these inputs are often contested in large claims. This is why economic and actuarial evidence plays an important role when future income loss is a major component of the claim.
What Reduces a Settlement Figure
The gross value of a claim is the sum of all heads of damage calculated at full value. The settlement figure is rarely the gross value. There are several factors that regularly reduce the amount which a claimant will receive.
Contributory negligence
If the claimant was partly at fault for their own injury because they failed to take reasonable care for their own safety, the settlement amount is reduced by their proportionate share of fault. Under the Civil Liability Act 2003 (QLD), contributory negligence is quantified as a percentage reduction and applied proportionally. So if a claim was quantified at $400,000 and the claimant was found to be 25% responsible for their own injuries, they would receive $300,000.
Insurers will often raise contributory negligence as a negotiation tactic. Whether it would be successful at trial depends on the particular facts. Just because contributory negligence is raised, it will not automatically reduce any claim.
Litigation risk discount
Even a strong claim carries some risk of not fully succeeding if it proceeds to trial. A settlement reflects a negotiated resolution of that risk. The insurer applies a discount representing the chance the claim might fail or succeed for less, and the claimant accepts a figure that avoids the cost and uncertainty of litigation.
For a claim with strong liability and clear causation, the risk discount is modest. For a claim where liability is contested or causation is disputed, the discount is larger.
Offsets and statutory repayments
Certain payments received during the claim period may need to be repaid from the settlement or reduce the damages calculated. In WorkCover matters, statutory benefits received reduce the amount available under a common law claim. Medicare may have a recovery right against personal injury settlements for treatment costs it funded. Social security payments received from Centrelink during incapacity can reduce certain heads of damage. These offsets are calculated and applied before the net payment is made.
Statutory caps and thresholds
Several heads of damage are subject to legislative caps or thresholds. Non-economic loss is subject to a maximum amount under the Civil Liability Act 2003 (QLD). Future income loss calculations use the prescribed discount rate regardless of what an individual actuary might recommend. Some claim types have a cap on the rate at which future income loss can be calculated. These legislative limits are fixed and apply to all claims of the relevant type.
How the Claim Type Affects the Calculation
The legislative framework governing a claim determines which heads of damage are available, what thresholds apply, and whether statutory entitlements run alongside or separately from a common law damages assessment.
| Claim Type | What Is Assessed | Legislative Framework |
|---|---|---|
| WorkCover (statutory claim) | Weekly compensation at a percentage of pre-injury earnings, subject to a statutory cap and maximum payment period. Funded medical and rehabilitation expenses. Lump sum for permanent impairment calculated by applying a prescribed dollar rate to the assessed degree of permanent impairment (DPI). Fault is not required for the statutory claim. | Workers’ Compensation and Rehabilitation Act 2003 (QLD) |
| WorkCover (common law claim) | Full assessment of economic and non-economic loss. Past and future income loss, medical expenses, (limited) care costs, and pain and suffering . Requires establishing employer negligence. Calculated under the general damages framework. The statutory and common law pathways interact: statutory payments received are offset against common law damages. | Workers’ Compensation and Rehabilitation Act 2003 (QLD) and Civil Liability Act 2003 (QLD) |
| CTP Motor Vehicle (Queensland) | All injured persons where the other party is at fault access full common law damages. There is no classification in Queensland CTP that restricts or limits access to the common law pathway, apart from proving the other driver was at fault. Where the insurer admits liability, rehabilitation expenses are funded upfront while the claim is assessed. Full assessment covers past and future income loss, medical and rehabilitation expenses, care costs, and pain and suffering (subject to the CLA 2003 threshold). | Motor Accident Insurance Act 1994 (QLD) and Civil Liability Act 2003 (QLD) |
| Public Liability | Full common law assessment. Medical and hospital expenses, lost income, care costs, home modifications, and pain and suffering (subject to CLA 2003 threshold). Fault must be established. Pre-court process under PIPA. The same heads of damage are available as for other common law personal injury claims. | Civil Liability Act 2003 (QLD) and Personal Injuries Proceedings Act 2002 (QLD) |
Settlement vs Judgment: Why Most Claims Resolve Without Court
The vast majority of Queensland personal injury claims are resolved by negotiated settlement rather than by a court judgment. A settlement is a binding agreement reached between the parties, typically at or before the compulsory conference required under PIPA. A judgment is a court’s determination of the claim’s value after a full hearing.
Both parties generally have incentives to settle. For the claimant, settlement provides certainty, avoids the time and cost of proceedings, and avoids the risk of a lower judgment. For the insurer, settlement avoids litigation costs, delay, and the possibility of a higher award than was offered.
The compulsory conference
Queensland’s pre-court process under PIPA requires the parties to exchange evidence and attend a compulsory conference before any court proceedings can commence. The compulsory conference is a structured negotiation with a professional mediator. Both parties attend with their legal representatives, and the insurer is expected to come with authority to settle.
The conference is the point at which both sides have seen each other’s medical and financial evidence and can negotiate with a realistic view of how the claim would be assessed at trial. Most claims resolve here. If settlement is not reached, the parties note the conference has failed and court proceedings become available.
WHY A SETTLEMENT MIGHT BE LESS THAN THE THEORETICAL MAXIMUM
A settlement reflects a negotiated outcome, not a court’s finding of full value. Factors that commonly produce a settlement below the gross calculated value include: disputed or uncertain liability, contested medical causation, contributory negligence, uncertainty in future projections, and the cost and risk of litigation. A settlement that properly accounts for these factors is often a better outcome than an uncertain and costly trial.
Legal representation and the calculation
Assessing the value of a personal injury claim is not a mechanical exercise. It requires understanding how courts and insurers approach specific types of injury and loss, how to structure and present medical and financial evidence, and how to respond to the insurer’s liability arguments and expert opinions. The evidence assembled, the submissions made at the compulsory conference, and the timing of negotiations all affect the outcome.
Claims that proceed without legal representation consistently settle for less than represented claims. Unrepresented claimants do not have access to the actuarial, vocational, and medical experts needed to establish the full value of a claim, and do not have the legal knowledge to identify and challenge insurer positions that are incorrect or overstated.
The Deed of Release: Why Timing Matters
Once a settlement is reached, the parties sign a deed of release. This is a binding contract under which the claimant releases the respondent from any further claims arising from the same accident in exchange for the agreed payment. Signing the deed ends the claim permanently.
A deed of release can only be set aside in very limited circumstances, such as fraud or a mutual mistake about a fundamental fact that existed at the time of signing. The fact that a condition worsens after settlement, or that a new diagnosis emerges later, does not allow the deed to be set aside.
| SETTLING BEFORE THE FULL PICTURE IS KNOWN |
|---|
| Settling before the full extent of an injury is established is one of the most common causes of under compensation in personal injury claims. If there is genuine medical uncertainty about prognosis, about the permanency of a condition, or about future treatment needs, those questions should be resolved before settlement is finalised. The right time to settle is when the evidence of loss is complete, not when the insurer makes its first offer or when the claimant wants the process to be over. |
Frequently Asked Questions
Personal injury settlements in Queensland are calculated by assessing each compensable category of loss, called a head of damage, using evidence specific to that category. Economic losses include past and future income loss, medical and rehabilitation expenses, care costs, and out-of-pocket expenses. Non-economic loss covers pain and suffering, under the Civil Liability Act 2003 (QLD) or Workers Compensation and Rehabilitation Act 2003 (Qld). Future losses are discounted to present value using a legislated discount rate. The resulting gross figure is then adjusted for contributory negligence, litigation risk, and any applicable statutory offsets. The adjusted figure forms the basis for negotiation at the compulsory conference.
Not a precise formula, more of a guideline. Under the Civil Liability Act 2003 (QLD) and Workers Compensation and Rehabilitation Act 2003 (Qld), the injury is calculated with reference to the injury scale value. Medical evidence by a treating specialist that addresses not just the injury, but the functional and lifestyle limitations it imposes will form the basis for assessment.
Future income loss, also called loss of earning capacity, is calculated by estimating the claimant’s likely pre-injury earnings over their remaining working life, then subtracting their estimated post-injury earning capacity over the same period. The resulting annual difference is applied over the number of years remaining and then discounted to a present lump sum value using the rate prescribed under the Civil Liability Act 2003 (QLD) and Workers Compensation and Rehabilitation Act 2003 (Qld).
Medical and economic/actuarial expert evidence is generally required to support significant claims for future income loss. Many factors will impact calculation of future loss of income including age, occupation, career progression to date, likely promotion path and post injury work capacity.
The amount you are offered in settlement will almost never match the pre-discounts calculated value of your claim. This is because the calculated value almost always reflects the maximum you could receive should you obtain a perfect result at trial – which is extremely rare. The factors that lead to reductions include; the risk that parts of your claim may not succeed at trial, your level of contributory negligence (if any), the savings both parties make by not engaging in lengthy and costly litigation, and unforeseen changes to future costs and needs. If an insurer offered every claimant who sued full value for the amount calculated at the outset of a claim, they would likely go bankrupt. Cases which involve no risk of an adverse outcome at trial are very rare. Assessing whether a settlement offer adequately compensates considers, at least in part, the very real risk that your claim could receive nothing at trial.
Statutory damages entitlements are set amounts defined by legislation. In the Workers’ Compensation scheme (commonly referred to as WorkCover), statutory benefits include weekly payments made as a percentage of pre-tax income, set amounts for defined categories of medical expenses, and a lump sum calculated at a rate set by regulation applied to the assessed impairment. Common law damages are assessed on an individual basis according to the unique facts of each injured person’s loss. Common law claims allow for compensation of pain and suffering, economic loss including future earning capacity, and care costs at amounts commensurate with actual loss instead of fixed statutory rates. In Queensland CTP claims the At-Fault party is always insured so all injured persons can access the common law pathway.
Only in very limited circumstances. A signed deed of release is a binding contract. The claim cannot be reopened because a condition worsens, because a new medical issue is identified, or because the claimant later believes they settled for too little. The only grounds that might allow a deed to be set aside are fraud, or a mutual mistake about a fundamental fact that existed at the time of settlement but was not known to the parties. These are high bars. Settling before the full extent of injury and prognosis is known carries real and permanent financial risk.
If the claimant contributed to their own injury by failing to take reasonable care for their own safety, their compensation is reduced by the proportion of fault attributed to them under the Civil Liability Act 2003 (QLD). A finding of 20% contributory negligence reduces a $300,000 claim to $240,000 received. The reduction is proportional and does not eliminate a claim unless the degree of contributory negligence is assessed at 100%, which is reserved for extreme cases. Insurers routinely raise contributory negligence as a negotiating position. Whether it would succeed at trial depends on the specific facts.
Personal injury compensation payments are generally not subject to income tax in Australia. The ATO does not consider compensation payments for personal injuries to be assessable income, whether that income is received as a lump sum payout or paid over time. Interest on received compensation, however, is taxable. Interest represents income earned by investing those settlement funds and is not considered compensation. If you have specific questions regarding the taxation of structured settlements it would be prudent to obtain independent financial advice.
