Chemical Engineer Salary: Converting Hourly Rates to Annual Pay Under the Professional Employees Award
Under the Professional Employees Award 2020, a Level 1 graduate chemical engineer with a 4-year degree earns $34.57 per hour, equating to about $68,538 per year based on a 38-hour week.
Understanding the Chemical Engineer Salary Landscape
If you're a chemical engineer in Australia, your pay is likely governed by the Professional Employees Award 2020 (MA000065). This award sets minimum hourly rates for professional classifications, from graduate level through to experienced professionals. Knowing how to convert your hourly rate to an annual salary is essential for comparing job offers, budgeting, and understanding your entitlements.
This guide explains the conversion using a 38-hour week, a fortnightly perspective, and a 52-week year. We'll also cover tax, superannuation, and the difference between the National Minimum Wage and award rates.
Award Rates for Professional Employees
The Fair Work Commission's Professional Employees Award 2020 includes specific pay points for chemical engineers. As of 1 July 2026, the minimum annual wages for full-time employees are:
- Level 1 Graduate professional – Pay point 1.1 (3-year degree): $66,825 per year ($33.71 per hour)
- Level 1 Graduate professional – Pay point 1.1 (4 or 5-year degree): $68,538 per year ($34.57 per hour)
- Level 1 Graduate professional – Pay point 1.2: $69,688 per year ($35.15 per hour)
- Level 1 Graduate professional – Pay point 1.3: $72,590 per year ($36.62 per hour)
- Level 1 Graduate professional – Pay point 1.4: $76,267 per year ($38.47 per hour)
- Level 2 Experienced professional: $78,836 per year ($39.77 per hour)
- Level 3 Professional: $86,157 per year ($43.46 per hour)
- Level 4 Professional: $97,173 per year ($49.02 per hour)
- Level 5 Experienced medical research employee: $117,064 per year ($59.05 per hour)
These rates are the minimum. Many chemical engineers earn above award, but the award provides a solid baseline for your chemical engineer salary.
Converting Hourly to Annual: The 38-Hour Week
Most full-time professional roles in Australia are based on 38 ordinary hours per week. To convert an hourly rate to an annual salary, use this formula:
Annual gross pay = hourly rate × hours per week × 52
For a chemical engineer on $34.57 per hour working 38 hours:
$34.57 × 38 × 52 = $68,538 per year
If you work part-time or different hours, adjust the weekly figure. For example, a part-time engineer working 20 hours per week at the same rate would earn $34.57 × 20 × 52 = $35,953 per year.
Fortnightly and Weekly Pay
Many employers pay fortnightly. To find your fortnightly gross pay, multiply your weekly pay by 2. Using the $34.57 per hour example:
- Weekly: $34.57 × 38 = $1,313.66
- Fortnightly: $1,313.66 × 2 = $2,627.32
Your fortnightly pay before tax and other deductions is $2,627.32. This is useful for budgeting, as many bills are due monthly or fortnightly.
National Minimum Wage vs Award Rates
The National Minimum Wage from 1 July 2026 is $26.44 per hour, or $1,004.90 per week for a 38-hour week. However, award-covered employees like chemical engineers must be paid at least the award rate for their classification, which is higher than the minimum wage. For casual employees, a 25% loading applies, bringing the casual minimum to $33.05 per hour. Under the Professional Employees Award, casual chemical engineers receive the award hourly rate plus 25% loading.
Tax and Super Considerations
Your annual gross pay is not what you take home. The Australian Taxation Office (ATO) applies progressive tax rates for 2026–27:
- $0 – $18,200: Nil
- $18,201 – $45,000: 15% of excess over $18,200
- $45,001 – $135,000: $4,020 plus 30% of excess over $45,000
- $135,001 – $190,000: $31,020 plus 37% of excess over $135,000
- $190,001+: $51,420 plus 45% of excess over $190,000
Plus a Medicare levy of 2% (with possible reductions for low incomes). For a chemical engineer earning $68,538, the estimated tax (including Medicare) would be around $12,000–$13,000, leaving a take-home pay of roughly $55,000–$56,000 per year.
Superannuation is paid on top of your salary. Your employer must contribute 12% of your ordinary earnings into a super fund. For $68,538, that's $8,225 in super contributions, bringing total remuneration to $76,763. Super is not part of your take-home pay but is a valuable retirement savings.
Casual Loading and Other Factors
If you work as a casual chemical engineer, you receive a 25% loading on top of the base hourly rate. For a Level 1 graduate (4-year degree), the casual rate is $34.57 × 1.25 = $43.21 per hour. This compensates for not receiving paid leave or other entitlements. When converting to annual, use the casual hourly rate in the formula, but remember that casual hours may vary.
Using the Timesheet Tool
Our timesheet tool lets you enter your base hourly rate and optionally add the 25% casual loading. It calculates your weekly, fortnightly, and annual gross pay, along with estimated tax and super. For more detailed award rates, refer to our pay guides or reference tables.
Important Disclaimer
Annual pay shown 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.
