How to Calculate Your Engineering Salary: Hourly to Annual Guide
For a full-time engineer on the Professional Employees Award, the annual salary is the hourly rate multiplied by 38 hours per week and 52 weeks, with super paid on top.
Introduction
If you’re an engineer in Australia, understanding how your hourly rate translates into an annual salary is essential for budgeting, negotiating, and planning your tax. This guide uses the latest Fair Work Ombudsman pay guides and the Professional Employees Award 2020 to show you exactly how to convert your engineering salary from hourly to annual, including the 38-hour week, casual loading, superannuation, and the tax you’ll pay.
The 38-Hour Week and Annual Conversion
The standard full-time working week under most awards, including the Professional Employees Award, is 38 ordinary hours. To calculate your annual gross pay, use the formula:
Annual gross = hourly rate × hours per week × 52
For example, a Level 1 graduate engineer (3-year degree) on $33.71 per hour earns:
$33.71 × 38 × 52 = $66,825 per year
This matches the annual wage in the award table. The same formula works for any hourly rate. If you work part-time, adjust the hours per week accordingly. For a fortnightly figure, simply multiply the weekly pay by 2.
Engineering Salary Under the Professional Employees Award
The Professional Employees Award 2020 sets minimum rates for engineers, scientists, and medical researchers. Here are key classifications:
| Classification | Hourly rate | Annual wage (38 hours) |
|---|---|---|
| Level 1 Graduate (3-year degree) | $33.71 | $66,825 |
| Level 1 Graduate (4 or 5-year degree) | $34.57 | $68,538 |
| Level 2 Experienced professional | $39.77 | $78,836 |
| Level 3 Professional/Senior | $43.46 | $86,157 |
| Level 4 Professional | $49.02 | $97,173 |
| Level 5 Experienced medical research | $59.05 | $117,064 |
These rates are the minimum – your actual engineering salary may be higher depending on experience, location, and enterprise agreements. Always check the pay guides on the Fair Work Ombudsman website for the latest figures.
Casual Loading and Superannuation
If you’re a casual engineer, you receive a 25% loading on top of the minimum hourly rate. For instance, a Level 2 casual would earn $39.77 × 1.25 = $49.71 per hour. This loading replaces entitlements like annual leave and sick leave.
Superannuation is paid on top of your ordinary earnings. From 1 July 2026, the super guarantee is 12% of your ordinary time earnings, up to the maximum contribution base of $270,830 per year. For a full-time engineer on $78,836, the employer contributes an extra $9,460.32 annually. This is not deducted from your pay – it’s additional.
Tax and Medicare on Your Annual Figure
Once you have your annual gross salary, you can estimate your take-home pay using the 2026–27 resident tax rates:
- Nil tax on the first $18,200
- 15% on income from $18,201 to $45,000
- 30% on income from $45,001 to $135,000
- 37% on income from $135,001 to $190,000
- 45% on income above $190,000
Plus the Medicare levy of 2% (with possible reductions for low-income earners). For a Level 2 engineer earning $78,836:
- Tax: $18,200 × 0% + ($45,000 – $18,200) × 15% + ($78,836 – $45,000) × 30% = $0 + $4,020 + $10,150.80 = $14,170.80
- Medicare: $78,836 × 2% = $1,576.72
- Total deductions: $15,747.52
- Estimated annual take-home: $63,088.48

Using the Timesheet Calculator
Our the timesheet calculator lets you enter your base hourly rate and optionally add casual loading. It then shows your annual, monthly, fortnightly, and weekly gross pay, along with estimated tax and super. The calculator uses the same 38-hour week assumption and the latest tax scales. It’s a quick way to see how your engineering salary stacks up.
Summary
Converting your engineering salary from hourly to annual is straightforward: multiply by 38 and by 52. The Professional Employees Award provides clear minimum rates, and the National Minimum Wage ($26.44 per hour) serves as a floor for award-free workers. Always check the award that applies to you, and remember that super is paid on top. For a full picture, use our hourly conversion guide and the timesheet calculator.
Disclaimer: Annual pay here is hourly rate × hours per week × 52. It assumes the same rate every week, no unpaid overtime, no penalty rates, no allowances, and no salary sacrifice. Super is estimated at 12% of ordinary earnings only, paid on top, and stops at the $270,830 maximum contribution base. Tax is the 2026–27 resident scale with the full tax-free threshold. Medicare uses the 2025–26 single reduction thresholds because the 2026–27 reduction thresholds were not confirmed here. HELP, the Medicare levy surcharge, and salary packaging are not deducted. This is an estimate, not a determination of your pay or tax.
