PIAWE Calculator - How To Calculate Your Weekly Earnings

The Workers Compensation Amendment Regulation 2018 (Amendment Regulation) has amended the Workers Compensation Act to make significant changes to the calculation of pre-injury average weekly earnings (PIAWE).

In this guide, we break down everything you need to know about PIAWE and how to calculate your weekly earnings.

PIAWE (pre-injury average weekly earnings) should be a fairly simple calculation however insurers regularly get it wrong.

What is PIAWE?

PIAWE (pre-injury average weekly earnings) is defined as; “The weekly average of the gross pre-injury earnings received by the worker during the period of 52 weeks before the injury in any employment in which the worker was engaged at the time of injury.”

Based on the definition of PIAWE, the insurer is required to obtain a copy of the pay slips for the 52 weeks immediately prior to the injury and calculate the average gross weekly earnings received by the worker during that period.

How Is PIAWE Calculated?

PIAWE is a fairly simple calculation however insurers regularly get it wrong.

It includes the calculation of “pre-injury average weekly earnings” and also the workers ordinary earnings as well as any overtime and/or shift allowance payment. The insurer must make a decision in writing in relation to the PIAWE rate and notify the worker of this decision.

What if I disagree with my PIAWE?

If you disagree with the amount calculated by the insurer, this can be challenged through the Workers Compensation Commission and you should discuss this with a lawyer.

Recent PIAWE Changes

The significant change that has been made by the amending regulations is that for those that are injured on or after 26 October 2018, overtime and shift allowances are no longer excluded from the calculation of the PIAWE rate after receiving 52 weeks of weekly compensation payments.

For anyone injured prior to 26 October 2018, the PIAWE is recalculated after you have received 52 weeks of weekly compensation benefits to reduce the PIAWE rate by excluding any overtime or shift allowance from the calculation.

This often resulted in a significant reduction in the weekly amount of compensation entitled to an injured worker. Often workers rely heavily on receiving overtime and shift allowance in their weekly wage.

This has been recognised by the government and changes made to the calculation of the PIAWE rate but only for people injured on or after 26 October 2018.

What Are The 4 Systems Of Determining the PIAWE Rate?

There are therefore 4 different systems for determining the PIAWE rate, depending on the date and circumstances of your injury.

  1. Coal Miners have a different method of calculating average weekly earnings.
  2. Exempt workers under the Workers Compensation Act (such as emergency workers) have a different method of calculating average weekly earnings.
  3. Those workers injured before 26 October 2018 as noted above.
  4. Those workers now injured on or after 26 October 2018 as noted above.

The government has simplified the calculation of weekly payments and made it much fairer by allowing a worker to receive essentially 80% of their pre-injury average weekly earnings including overtime and shift allowance.

PIAWE Calculation Examples

Example 1:

If you are trying to figure out your compensation for the first 52 weeks you will need to include your pre-injury ordinary earnings and any overtime or allowances.

Week 1
Ordinary Earnings / Week: $800.00
Overtime / Week: $300.00
Allowances / Week: $45.00
Total: $1145.00

 

Week 2
Ordinary Earnings / Week: $900.00
Overtime / Week: $150.00
Allowances / Week: $45.00
Total: $1095.00

You may have earnt a different amount of money each week. In order to calculate the average you will need to get the totals from the 52 weeks prior to the injury date. You then need to add the totals together and divide them by 52.

Total earnings for 52 weeks ÷ 52= PIAWE

Example 2:

If you are trying to figure out your compensation after the first 52 weeks you will need to exclude any overtime and allowances. You can only use your ordinary earnings.

Week 1
Ordinary Earnings / Week: $800.00
Total: $800.00
Week 2
Ordinary Earnings / Week: $900.00
Total: $900.00

In order to calculate the average you will need to get the totals from the 52 weeks prior to the accident date. You then need to add the totals together and then divide them by 52.

Total earnings for 52 weeks ÷ 52 = PIAWE

My last stage of Workers compensation claim was managed by Emma Perkins, Natasha Stojanovic, Rebecca Dunshea and Kelli Robinson at Garling and Co. Lawyers who went the extra mile with their service... from the beginning to the end of 3 years of my case. I have become very anxious with almost everything after a workplace injury and a lot of times I probably ask more questions than I need to, but Emma Perkins always finds clear answers to my questions in a short time and explains to me patiently even using her mealtime or between her meeting and make me feel that I have been very well take care and supported. I am so grateful and extremely satisfied. The excellent service, attitude, and culture of Metthew Garling and his team are second to none with a very high success rate. If you going to battle with your workplace injury for a short or long period, you are better off with Garling and Co. lawyers who are able back you up every step of the way.

Work cover fund is GOVT’S money but insurer think that it is from their 14th generation. So only they can have it. Not only that, people from the work, IME doctor from insurer, back to work... coordinator from work, Rehab provider from any side push the worker as hard as possible that the worker (doesn’t matter how the workers mental or psychical condition) either go back to his pre injury duty or leave the job.More over on that very bumpy any difficult journey some of them only treat the worker as a MONEY MAKING MECHINE .in some point worker feels like, no rooms to breath. On that moment need someone to support legally, someone to care, someone to relive.On my case I believe that, somehow, I manage to make my God happy. That’s why God sends me to Matthew Gerling and his team Allison, Rebecca and Nathan, and all of GARLING & co Lawyers.I am not good enough in English, can’t express my gratitude.Matthew, Allison, Rebecca and Nathan, please accept my appreciation and pass it to others.read more
