What does a salary on-costs calculator Australia include?

A salary on-costs calculator typically adds employer obligations such as superannuation guarantee (12% from 1 July 2026), payroll tax, workers’ compensation insurance, and leave loading. It shows the total cost of employing someone, not just the gross salary. The legal minimum wage itself is only part of that cost.

How does the national minimum wage relate to a salary on-costs calculation?

The national minimum wage is the lowest hourly or weekly pay an award-free adult employee can receive before on-costs. When using a salary on-costs calculator, you enter the gross salary or wage, and the calculator adds super and other costs. The resulting total must be at least the minimum wage plus the 12% super (i.e., $29.61 per hour in total employer cost for a full-time adult).

Can a salary on-costs calculator tell me if I am underpaid?

No, a salary on-costs calculator only estimates total employer cost. To check if you are underpaid, you need to know your correct classification under a modern award or enterprise agreement. The Fair Work Ombudsman’s Pay and Conditions Tool is the official way to check your minimum entitlements. A salary on-costs calculator does not replace that.

Salary On-Costs Calculator Australia: Compare Your Rate with the Legal Minimum

The national minimum wage from 1 July 2026 is $26.44 per hour or $1,004.90 per week for adult award-free employees, with super of 12% on top.

Understanding the salary on-costs calculator Australia and the minimum wage

When you search for a salary on-costs calculator Australia, you are likely trying to work out the true cost of employing someone or to see how your own pay compares with the legal floor. This guide explains the key figures you need to know, starting with the national minimum wage and the extra costs an employer must pay on top.

The legal minimum wage for award-free adults

From 1 July 2026, the Fair Work Commission set the national minimum wage at $26.44 per hour or $1,004.90 per week for a full-time adult employee working 38 ordinary hours. This rate applies to national-system employees who are not covered by a modern award or enterprise agreement. The employer must also pay superannuation guarantee of 12% on top of ordinary time earnings, making the minimum total employer cost about $29.61 per hour.

How an award rate can differ

If you are covered by a modern award, the minimum hourly rate for your classification may be higher than the national minimum. For example, the award backstop from 1 July 2026 is also $26.44 per hour, but many award classifications are above that. Introductory rates for the first six months can be as low as $25.74 per hour. Always check the relevant award using the Fair Work Ombudsman’s resources. A salary on-costs calculator should let you enter your award rate to get an accurate total cost.

Survey averages and negotiated salaries

The Australian Bureau of Statistics (ABS) reported in May 2026 that full-time adult ordinary-time earnings averaged $2,083.70 per week, and all employees averaged $1,579.20 per week. These are survey averages, not legal minimums. A negotiated salary can be above or below these averages, but it must never fall below the applicable minimum wage or award rate. When using a salary on-costs calculator, remember that the average is not a floor.

What a salary on-costs calculator adds

A typical salary on-costs calculator includes:

Gross salary or wage
Superannuation guarantee (12% from 2026-27)
Payroll tax (varies by state and threshold)
Workers’ compensation insurance premium
Leave loading (if applicable)
Other costs such as fringe benefits tax or training levies

The result is the total employment cost. For a worker on the national minimum wage, the employer’s total cost is at least $29.61 per hour. If you are comparing a job offer, use the calculator to see the full picture.

Important distinctions

Legal minimum: Set by the Fair Work Commission, enforced by the Fair Work Ombudsman. It is the lowest lawful pay.
Award rate: A higher minimum set by a modern award for a specific industry or occupation.
Enterprise agreement rate: A negotiated rate that must pass the better-off-overall test.
Survey average: A statistical figure from the ABS, not a legal requirement.

A salary on-costs calculator cannot tell you which of these applies to you. For that, see Which minimum wage applies or check the Rate tables on this site.

Superannuation is an employer cost on top

Super guarantee is 12% of ordinary time earnings, paid by the employer into a super fund. It is not deducted from the employee’s gross wage. When you use a salary on-costs calculator, ensure it adds super as a separate line item. The national minimum wage figures on this site are before super; the total employer cost includes super.

When a lower rate is allowed

Not every worker must receive $26.44 per hour. Junior employees (under 21), apprentices, trainees, and some employees on introductory award rates can be paid less. For award-free juniors, the percentages range from 36.8% for under 16 to 97.7% for 20-year-olds. Apprentice and trainee rates follow the Miscellaneous Award. A salary on-costs calculator should allow you to enter these lower rates if applicable.

Using the calculator responsibly

A salary on-costs calculator is a tool for estimation. It does not replace legal advice or the Fair Work Ombudsman’s Pay and Conditions Tool. If you are unsure about your entitlements, consult the Guides on this site or contact the Fair Work Ombudsman directly.

Summary

The national minimum wage from 1 July 2026 is $26.44 per hour or $1,004.90 per week for adult award-free employees. Super of 12% is paid on top. A salary on-costs calculator Australia helps you see the total employer cost, but you must first know the correct minimum wage or award rate for your situation. Use the resources on this site to find that rate, then apply the calculator to get the full picture.
