Employee Cost Calculator Australia: Real Cost per Hour

An employee cost calculator for Australia works out the true cost of employing someone, not just their gross salary. You enter the annual salary and a few details like superannuation, leave loading, and on-costs, and it returns the total yearly cost and the real cost per hour or per day. This figure matters because the gap between the salary you advertise and what you actually pay can be 15–30% higher once mandatory and optional costs are added.

Formula

The calculator uses a standard on-cost model. The total annual cost is:

Total Cost = Salary × (1 + Super% + Workers Comp% + Payroll Tax%) + Leave Loading Amount + Other Costs

Where:

• Salary – gross annual salary in AUD (before tax).
• Super% – the Superannuation Guarantee rate (currently 11.5% for 2024–25, rising to 12% by 2025–26).
• Workers Comp% – workers compensation insurance premium as a percentage of wages (varies by industry and state).
• Payroll Tax% – state payroll tax rate (only applies if your total wages exceed the threshold; rates vary from 1.5% to 6.5%).
• Leave Loading% – extra pay on annual leave (typically 17.5% for awards, but can be 0 if not applicable).
• Leave Loading Amount – calculated as Salary × (Leave Loading% / 100) × (4 weeks of leave / 52 weeks).
• Other Costs – any additional costs like training, equipment, uniforms, or fringe benefits.

The hourly cost divides the total by the number of working hours in a year: 38 hours per week × 52 weeks = 1,976 hours (or 2,080 if you use 40 hours).

Worked Example

Using the default values from the calculator:

1. Start with a gross salary of $80,000.
2. Add superannuation at 11.5%: $80,000 × 0.115 = $9,200.
3. Add workers comp at 2.0%: $80,000 × 0.02 = $1,600.
4. Add payroll tax at 4.85%: $80,000 × 0.0485 = $3,880.
5. Calculate leave loading: $80,000 × 17.5% × (4/52) = $80,000 × 0.175 × 0.076923 = $1,076.92.
6. Add other costs: $2,000.
7. Total = $80,000 + $9,200 + $1,600 + $3,880 + $1,076.92 + $2,000 = $97,756.92.
8. Hourly cost = $97,756.92 / (38 × 52) = $97,756.92 / 1,976 = $49.47 per hour.
9. Daily cost = $49.47 × 7.6 = $375.97 per day.

So an $80,000 salary actually costs about $97,757 per year, or roughly $49.47 per hour.

Why the True Cost Matters

Many small business owners budget based on the gross salary and are surprised when their accountant shows a much higher figure. The difference can affect cash flow, pricing, and hiring decisions. For example, if you’re comparing a full-time employee to a contractor, the contractor’s rate may look higher, but once you add super, leave, workers comp, and payroll tax, the employee often costs more than you think. Knowing the real cost helps you set realistic budgets, decide between hiring and outsourcing, and price your goods or services correctly.

What to Include in Your Calculation

Here are the typical components that make up the true cost of an employee in Australia:

• Superannuation Guarantee – compulsory contribution of 11.5% of ordinary time earnings (2024–25), paid at least quarterly.
• Payroll tax – state-based tax on wages above a threshold (e.g., in NSW the threshold is $1.2 million, so most small businesses don’t pay it).
• Workers compensation insurance – premium varies by industry and state; can range from 1% to 10% of wages.
• Annual leave loading – extra 17.5% on top of the 4 weeks of annual leave, if the award or agreement requires it.
• Leave entitlements – annual leave (4 weeks), personal/carer’s leave (10 days), and long service leave (after 10 years). These are paid days where the employee isn’t producing revenue.
• Other on-costs – recruitment, training, uniforms, tools, phone, laptop, parking, and fringe benefits tax (FBT) if you provide certain benefits.

Common Mistakes and Misconceptions

One common mistake is forgetting that super is calculated on ordinary time earnings, not just base salary – so overtime, bonuses, and commissions may also attract super. Another is assuming payroll tax applies to every business; in most states, you only pay it if your total wages exceed a threshold (e.g., $1.2 million in NSW, $1.3 million in Victoria). Also, many people confuse the hourly cost with the wage rate – the hourly cost is what the business pays, not what the employee takes home. Finally, leave loading is often overlooked because it’s not a weekly cost, but it adds up when the employee takes leave.

How to Use the Calculator Effectively

Start with the gross annual salary, then adjust the super rate to the current legal minimum (11.5% for 2024–25, but check if your award requires more). For workers comp, use the rate from your insurer – it varies by industry (e.g., office work is low, construction is high). Payroll tax rate should be set to 0 if your business is below the threshold; otherwise, use your state’s rate. Leave loading is 17.5% for most award-covered employees, but 0 for some salaried roles. Add any other costs you actually incur, like training or equipment. The result gives you a realistic annual cost, which you can then divide by the number of hours the employee actually works (excluding leave) to get a true hourly cost.

Limitations of the Calculator

This calculator provides an estimate, not a precise quote. It doesn’t account for the cost of leave days (which reduce productive hours), long service leave accrual, or the opportunity cost of management time. It also assumes a full-time, permanent employee – for part-time or casual, the calculations differ (casuals get a 25% loading instead of paid leave). Tax deductions and GST credits are not included because they vary by business. For a full financial analysis, consult an accountant or use payroll software that includes all on-costs.

Frequently Asked Questions

How much does an employee really cost in Australia?

On average, the total cost is about 15–30% above the gross salary. For an $80,000 salary, that’s roughly $92,000–$104,000 per year, depending on super, workers comp, and payroll tax. The calculator above gives a precise figure based on your inputs.

Is superannuation included in the salary?

No. The advertised salary is usually exclusive of super. The employer must pay super on top of the salary, currently 11.5% of ordinary time earnings. So if you advertise $80,000, the super cost is an additional $9,200.

What is the difference between employee cost and contractor cost?

An employee costs you super, leave, workers comp, and payroll tax, while a contractor typically invoices you a flat rate with no extra on-costs. However, contractors may charge a higher hourly rate to cover their own overheads. Compare the total cost per hour of an employee (using this calculator) with the contractor’s rate to see which is cheaper.

Do I have to pay payroll tax for a small business?

Only if your total wages exceed the threshold in your state. For example, in NSW the threshold is $1.2 million per year, so most small businesses don’t pay it. If you’re below the threshold, set the payroll tax rate to 0 in the calculator.

How do I calculate the cost of a casual employee?

Casuals get a 25% loading instead of paid leave, so the formula is simpler: total cost = (hourly rate × 1.25) × hours worked, plus super and workers comp. There’s no leave loading or annual leave accrual. Use a different calculator or adjust the inputs manually.

What is the current super guarantee rate?

For the 2024–25 financial year, it’s 11.5%. It increases to 12% from 1 July 2025. Always check the ATO website for the current rate, as it has been rising gradually.
