WorkCover Premium Calculator Australia

What the workcover premium calculator does

The workcover premium calculator turns a wages figure into the workers compensation cost an employer actually books, using the average premium rate for the state where the work is performed or the industry rate from your own policy schedule. It adds superannuation to the remuneration base the way most schemes do, applies any claims experience factor, and then reports the annual, GST-inclusive and monthly figures side by side.

It is a budgeting tool, not a quote. The number that ultimately appears on your renewal is set by your insurer or scheme agent from your industry classification and your claims record. What the calculator gives you is a defensible figure to plan around, and a way to test what a change in wages, state or claims performance would do to it.

How workers compensation premiums are built

Every Australian scheme uses the same skeleton. A rate is applied to remuneration, and adjustments are layered on top.

Remuneration is broader than base salary. It generally takes in wages, salaries, allowances, overtime, bonuses, commissions, directors fees, the grossed-up taxable value of fringe benefits, and employer superannuation contributions. Payments to some contractors deemed to be workers are also caught, which surprises businesses that assumed a contract removed the exposure.

The rate is set from your industry classification, a code describing what your business actually does, not what it is called. Office-based professional services sit at the bottom of the range; construction, agriculture, road transport, manufacturing and aged care sit near the top. The gap between the two ends is a multiple, not a few points, which is why classifying correctly matters more than negotiating.

The experience adjustment applies once an employer is large enough for their own claims to be statistically meaningful. Below that threshold, the industry rate is applied as published and the premium moves only with wages.

Why the state matters

Workers compensation is a state responsibility, so an employer operating across borders is dealing with several schemes at once. New South Wales, Victoria, Queensland, South Australia and Western Australia each run their own arrangements, with different definitions of remuneration, different thresholds for experience rating, different treatment of contractors and different renewal cycles. The Northern Territory and the Australian Capital Territory operate privately underwritten schemes.

The practical consequence is that the same employee costs a different amount depending on where they work, and cover has to be held in each state where you have workers. The calculator applies one state at a time, so a multi-state employer should run it once for each state with the wages attributable to that state.

The formula behind the result

Remuneration base is wages plus employer super, where the scheme counts it. Base premium is the remuneration base multiplied by the premium rate. Annual premium is the base premium multiplied by the experience factor. The GST-inclusive figure is the annual premium multiplied by one plus the GST rate.

The premium as a share of wages is reported separately from the rate itself, and the two are not the same number. Because super is inside the base but outside the wages figure, the effective cost per dollar of wages is always a little higher than the headline rate.

Reading your result

Look first at the premium as a share of wages. That is the figure to carry into a chargeout rate or a job cost, because it is expressed against the number you already budget with.

Then look at the premium on superannuation. It is the part employers most often forget when they cost a pay rise: lifting wages lifts super, and lifting super lifts the premium, so the true marginal cost of a raise is larger than the raise plus super alone.

Finally, compare your premium with the premium at the state average rate. A business sitting well above the average is either in a genuinely hazardous industry or carrying a loading it may be able to work down. A business sitting well below it should check the classification is right, because an under-classified policy can be re-rated retrospectively.

Reducing the premium legitimately

• Check your industry classification against what the business actually does now, not what it did when the policy was written.
• Report injuries early and manage return to work actively. In experience-rated schemes the cost of a claim is driven by its duration far more than by its severity at the outset.
• Keep the wages declaration accurate. Over-declaring wastes money immediately; under-declaring produces an adjustment and, in several schemes, a penalty.
• Review contractor arrangements. Deemed-worker rules capture more relationships than most employers expect, and an unexpected inclusion at audit is expensive.
• Ask what the renewal assumed. Premiums are usually struck on estimated wages and reconciled to actual at the end of the period, so an estimate that no longer reflects your headcount is worth correcting during the year rather than after it.

Limitations to keep in mind

• The seeded rates are scheme averages. Your real rate is industry-classified and can be several times higher or lower, so enter it whenever you have it.
• Scheme-specific mechanics, including minimum and maximum premiums, apprentice and small-employer concessions, dust disease levies, and the exact experience-rating formula, are not modelled.
• Remuneration definitions differ between states, particularly on contractors and fringe benefits.
• The tool covers one state at a time.

The state average rates, the super guarantee rate and the GST rate this tool uses are kept up to date, so the estimate reflects current settings. Treat the output as an estimate for budgeting, and confirm the premium with your scheme agent, insurer or broker before you rely on it.
