What is Whole Person Impairment (WPI) in Workers Compensation?
When diving into the world of workers compensation claims, you’ll often hear the term ‘Whole Person Impairment’ (WPI). If you’ve been hurt or gotten sick because of your job, your WPI percentage is essential for figuring out what types of compensation you’re entitled to and figuring out your compensation.
What is Whole Person Impairment?
Whole Person Impairment (WPI) measures how an injury or illness affects your overall health. It assesses both physical and psychological conditions, showing not just the seriousness of your injury but also how it affects your mood, daily activities, and overall quality of life.
In Queensland, WPI is referred to as DPI (Degree of Permanent Impairment). To keep things straightforward, we’ll stick with the term WPI for the rest of this post.
Why WPI can make or break your claim
Your WPI isn’t just a medical score — it's the key to a life-changing payout. In Australia, every state has its own 'threshold' that dictates what you're allowed to claim.
If you're below the threshold, you're stuck with basic weekly payments that may be capped after a year or two. But if you're above the threshold, you unlock the right to sue for hundreds of thousands of dollars, covering things like future lost income, superannuation, and pain and suffering.
Being 1% short of the threshold can cost you your entire settlement. That’s why having an expert lawyer audit your WPI score isn't just a good idea — it’s a financial necessity.

How is WPI assessed?
Your WPI is evaluated by an independent doctor who specialises in your type of injury. If your condition is psychological, a registered psychiatrist will conduct the WPI assessment instead.
The evaluation follows specific guidelines that can vary slightly depending on your state. Typically, the assessor will consider:
- Whether your condition has stabilised, meaning it's unlikely to change with time or further treatment.
- How your injury or condition affects your daily life.
- The established medical guidelines and criteria for permanent impairment in your state.
- Any previous injuries, pre-existing conditions, or other factors that might contribute to your impairment.
After reviewing all the information, your WPI is calculated based on your state’s guidelines and a report is prepared outlining your WPI percentage and any recommendations for future treatment or care.

The ‘hidden’ percentages that build your WPI
Most lawyers just look at your main injury and call it a day. But a WPI threshold isn’t usually reached with one big number — it’s built piece by piece. An experienced lawyer digs into the secondary impacts of your injury.
- How does any scarring impact you? It’s not just about a mark; it’s about how a scar affects your self-esteem and your life. A real conversation about scarring can add the final 1% or 2% you need to cross the threshold.
- Does your medication cause issues? Are your painkillers causing digestive issues or stomach problems? Under the AMA-5 guidelines, these side effects are valid percentages that belong in your claim.
- Are you having trouble sleeping? If your injury or a psychological condition has ruined your ability to sleep, that is a loss of function and can be added to your WPI percentage.
These are just a few of leading questions a good lawyer will ask to unearth every impact of your injury. By connecting these dots under the AMA-5 rules, we’ll build your WPI percentage by percentage until you hit the threshold for a lump sum payout.
What is WPI in workers compensation claims?
If you’re injured or ill because of work, you’re usually entitled to basic workers compensation payments, no matter your impairment level. This includes:
- Weekly wage-replacement payments (up to 95% of your pre-injury income).
- Medical costs.
- Rehabilitation and other support services.
- Travel expenses to and from treatment.
These weekly payments typically last for a set period, which varies depending on which state you’re in. To keep receiving payments beyond this period, you’ll need to meet the minimum WPI percentage shown in the table below.
| State | Threshold | What happens to your payments |
| NSW | 21% | If you hit 21%, your weekly payments can continue until you retire. If you’re under this, the insurer can stop your payments after 5 years. |
| VIC | 21% | Payments usually stop at 130 weeks (around 2.5 years). To keep receiving payments, you need to be at 21% and unable to return to work. |
| QLD | 20% DPI | If you reach 20%, you can take your lump sum and still sue for negligence. If you’re under 20%, you usually have to choose one or the other. |
WPI ratings for common workplace injuries
From our experience, these are some of the most common workplace conditions and the approximate WPI you could receive for each:
- Amputated finger: usually in the range of 20% to 30%, based on which finger is amputated. For example, losing a thumb usually results in a higher percentage than losing a pinkie.
- Back injury: generally between 10% and 30%.
- Knee injury (e.g. ACL tear): usually between 10% and 20%.
- Shoulder injury (rotator cuff tear): typically between 10% and 30%.
- Severe burns: usually from 30% to 60%, depending on how severe the burns are and which parts of the body are affected.
- Multiple injuries (e.g. fractured arm and leg): you can combine the WPI from multiple injuries into one total percentage.
- Hearing loss in both ears (binaural): your WPI is half your percentage of binaural hearing loss, e.g. if you have 30% binaural hearing loss, your WPI is 15%.
- Loss of vision in one eye: 30% to 40%.
- Psychological injury (e.g. PTSD): this varies hugely, from as little as 5% up to 65%, depending on the severity of the psychological injury and how it impacts your daily life and functioning.
It’s important to remember that these figures are general estimates and should be viewed as starting points. The exact WPI rating depends on your specific condition, how severe it is, and which state you live in. For a more precise estimate of your potential WPI, chat with an expert workers compensation lawyer.
What if my injury or illness is permanent?
On top of your weekly payments, you might also be able to get a WPI lump sum if your injury is permanent and you hit your state’s minimum threshold.
The table below shows the WPI percentage you need in each state.
| State | Minimum threshold |
| New South Wales | • Physical injuries: 11%
• Psychological injuries: 15% |
| Victoria | • Spinal injuries: 5%
• Other physical injuries: 10%
• Psychological injuries: 30%
|
| Queensland | 0% |
If your state doesn’t set a minimum WPI requirement, the size of your lump sum payment will still depend on the severity of your condition. In other words, the more serious your impairment, the larger your payout is likely to be.
What happens if employer negligence caused my injury?
If your employer’s negligence led to your injury, you may have a common law damages claim. To be eligible, you’ll typically need to meet your state’s minimum WPI threshold.
| State | WPI threshold |
| New South Wales | 15% |
| Victoria | 30% or pass a ‘serious injury’ test |
| Queensland | 0% |
It’s important to know that even in states without a minimum WPI, your level of impairment will still affect your compensation.
