Forensic Science Salary: Converting Your Hourly Rate to Annual Pay
For a forensic scientist earning $35 per hour, the annual gross pay is approximately $69,160 based on a 38-hour week and 52 weeks per year.
Understanding the Hourly to Annual Conversion
When you’re offered a job in forensic science, the pay is often quoted as an hourly rate. To compare that with a salary or to plan your budget, you need to convert it to an annual figure. The standard approach is to multiply your hourly rate by the number of hours you work each week and then by 52 weeks in a year. For most full-time roles in Australia, the ordinary hours are 38 per week, as set by the Fair Work Act and many modern awards.
The Formula
Annual gross pay = hourly rate × hours per week × 52
For a forensic scientist working 38 hours a week, this becomes:
Annual gross pay = hourly rate × 38 × 52
If you’re paid fortnightly, your gross pay each fortnight is simply the weekly amount doubled:
Fortnightly gross pay = hourly rate × 38 × 2
This calculation assumes you work the same number of hours every week, with no unpaid overtime, no penalty rates, and no allowances. It’s a starting point for understanding your total remuneration.
Finding the Correct Hourly Rate for a Forensic Scientist
A forensic science salary isn’t a single figure—it depends on your classification, experience, and the award that covers your role. Many forensic scientists in Australia are employed under the Health Professionals and Support Services Award 2020. The Fair Work Commission’s Modern Awards Pay Database contains the minimum rates for each classification, including the changes that took effect from 1 October 2026 following the gender-based undervaluation review.
You can also use the Fair Work Ombudsman’s pay guides to find the minimum pay rates for your award. These guides include full-time, part-time, and casual rates, as well as monetary allowances and common penalty rates. For example, if you’re a casual forensic scientist, you’re entitled to a 25% casual loading on top of the base hourly rate. The National Minimum Wage from 1 July 2026 is $26.44 per hour for permanent employees and $33.05 per hour for casuals (including the 25% loading).
Award vs. Enterprise Agreement
If your employer has an enterprise agreement that covers you, the pay rates in that agreement apply instead of the award. Always check your employment contract and the applicable industrial instrument. The Fair Work Ombudsman’s Pay and Conditions Tool can help you determine the correct minimum rates.
From Hourly to Fortnightly and Annual
Let’s walk through an example. Suppose a forensic scientist earns $35 per hour under the Health Professionals and Support Services Award. Assuming a 38-hour week:
- Weekly gross: $35 × 38 = $1,330
- Fortnightly gross: $1,330 × 2 = $2,660
- Annual gross: $35 × 38 × 52 = $69,160
If the same employee is casual, the hourly rate would be $35 plus 25% loading = $43.75 per hour. Then:
- Annual gross (casual): $43.75 × 38 × 52 = $86,450
Remember that casual loading is paid in lieu of entitlements like paid leave. Our casual loading page explains this in more detail.
Using the Timesheet Tool
Our timesheet lets you enter your base hourly rate and optionally add the 25% casual loading. It then calculates your annual, fortnightly, and weekly gross pay instantly. Never enter a rate that already includes casual loading—use the checkbox instead.
Tax and Super Considerations
Once you have your annual gross figure, you need to estimate your take-home pay after tax and the superannuation your employer pays on top.
Tax (2026–27 Resident Rates)
| Taxable income | Tax on this income |
|---|---|
| $0 – $18,200 | Nil |
| $18,201 – $45,000 | 15c for each $1 over $18,200 |
| $45,001 – $135,000 | $4,020 plus 30c for each $1 over $45,000 |
| $135,001 – $190,000 | $31,020 plus 37c for each $1 over $135,000 |
| $190,001+ | $51,370 plus 45c for each $1 over $190,000 |
Plus the Medicare levy of 2% (using the 2025–26 single reduction thresholds as the 2026–27 thresholds were not confirmed here). For a $69,160 annual gross, the tax would be approximately:
- Tax on first $18,200: $0
- Tax on $18,201 to $45,000: ($45,000 - $18,200) × 0.15 = $4,020
- Tax on $45,001 to $69,160: ($69,160 - $45,000) × 0.30 = $7,248
- Total tax: $4,020 + $7,248 = $11,268
- Medicare levy (2% of $69,160): $1,383.20
- Total tax and Medicare: $12,651.20
Your estimated annual take-home pay would be $69,160 - $12,651.20 = $56,508.80.
Superannuation Guarantee
Your employer must pay superannuation of 12% of your ordinary earnings on top of your salary, up to the maximum contribution base of $270,830 per year. For a $69,160 salary, the super contribution is $69,160 × 0.12 = $8,299.20 per year. This is paid into your super fund and is not included in your take-home pay. See our super and packaging page for more details.
Important Disclaimer
The calculations above are estimates. They assume the same rate every week, no unpaid overtime, no penalty rates, no allowances, and no salary sacrifice. Tax uses 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.
Using the Reference Tables
For a more precise forensic science salary, consult the Fair Work Commission’s reference tables for your specific award classification. The Modern Awards Pay Database provides detailed spreadsheets of minimum rates, allowances, and penalty rates. The Fair Work Ombudsman’s pay guides are also updated regularly to reflect the latest wage reviews.
Key Takeaways
- Use the formula: hourly rate × hours per week × 52 for annual gross.
- For a 38-hour week, multiply hourly rate by 38 for weekly, then by 52 for annual.
- Fortnightly pay is weekly × 2.
- Check your award or enterprise agreement for the correct minimum rate.
- Casual employees get a 25% loading on top of the base rate.
- Super is 12% paid on top of ordinary earnings, up to the cap.
- Tax is progressive with the Medicare levy.
