Pricing and calculation
Policy premiums are collected to cover the cost of claims and associated expenses when someone is injured at work.
The premium you pay for your workers compensation policy is determined by a number of different factors.
- the wages you pay to your workers
- your premium risk category or categories
- claims experience (the cost of workers compensation claims)
- the size of your business (based on wages).
Calculating your premium
Your base premium is determined by multiplying your wages by your premium risk category rate. That premium is then adjusted for your size (based on your wage roll) and finally, discounted or increased based on how your claims experience compares to the other employers in your risk category.
Your premium calculation sheet that is sent with your renewal notice each year clearly sets out the premium formula and enables you to see how your performance compares to others in your premium risk category or categories. It also provides you with a clearer view of how your own injury prevention and injury management performance affects your final premium rate.
Premium capping arrangements 2020-21
On 14 May 2020, the Coal Mines Insurance Board (Board) met to consider the premium pricing matters for the 2020-21 policy year. In addition to the usual considerations, the Board also took into account the unique health, social and economic circumstances arising from the COVID-19 pandemic and potential impacts on the NSW coal industry.
Consequently, the Board made the following decisions for the 2020-21 policy year:
- To hold the CMI Scheme target premium collection rate at the 2019-20 rate.
- That the existing premium rate movement capping arrangements of +/-30% be retained and then cease from the 2021-22 policy year.

The minimum premium rate
The minimum premium rate ensures all employers pay their fair share of the Scheme’s administration costs. This includes the fixed costs of underwriting each policy and other non-claim related expenses.
For the 2023-24 policy year the minimum premium rate is set at 1.06 per cent.
The minimum premium payable on any CMI policy including short term periods of insurance is $200.00 + (Plus Mine & Petroleum Site Safety Levy if applicable) + GST.
Premium categories that reflect your risk
Coal Mines Insurance (CMI) allocates covered wages to six premium risk categories that best reflect the specific risk exposures associated with different activities undertaken across the coal industry.
The multi-category policy model allows policyholders to declare wages in more than one premium risk category and have their final policy premium rate calculated on that basis. This means that your policy premium rate will be closely aligned to the overall risk profile of your business.
Questions to ask yourself when determining your risk category(ies):
- What are my day to day business activities whilst on a coal mine?
- Where on a mine site are my activities performed? e.g. underground, in the pit of an open cut mine, coal preparation plant, workshop, office etc.
- If my business activities are performed in different areas of a mine site or both on and off a mine site, how much time do I spend on each activity?
- What activities do I perform whilst not on a coal mine that is related to the coal mining industry?
