How do I convert my hourly rate to an annual salary?

Multiply your hourly rate by the number of hours you work each week, then by 52. For a standard full-time week of 38 hours, the formula is: hourly rate × 38 × 52. This gives your gross annual pay before tax and super. For example, $45 per hour × 38 × 52 = $88,920 per year.

What is the national minimum wage for 2026–27?

From 1 July 2026, the national minimum wage is $26.44 per hour, or $1,004.90 per week for 38 ordinary hours. Casual employees receive a 25% loading, making the casual rate $33.05 per hour. These rates are set by the Fair Work Commission.

Q: Does superannuation count as part of my salary?

No. Superannuation is paid on top of your salary. From 1 July 2026, the super guarantee is 12% of your ordinary earnings, up to the maximum contribution base of $270,830 per year. For a biologist earning $88,920, the employer would contribute an extra $10,670.40 into your super fund, but this is not included in your take-home pay.

For a biologist earning $45 per hour, the annual gross pay is approximately $88,920 based on 38 hours per week, before tax and super.

Understanding the Hourly to Annual Conversion

If you’re a biologist considering a job offer or negotiating your pay, converting an hourly rate to an annual salary is a straightforward calculation. The standard formula used across Australia is:

Annual gross pay = hourly rate × hours per week × 52

This assumes you work the same number of hours every week, with no unpaid overtime, penalty rates, or allowances. For full-time work, the typical week is 38 ordinary hours, as defined by the Fair Work Act. You can use the timesheet to quickly run your own numbers.

Why 38 Hours?

The 38-hour week is the standard for the national system. The Fair Work Commission sets the national minimum wage based on 38 hours. If you work more or fewer hours, adjust the formula accordingly. For part-time or casual roles, your weekly hours may vary.

Biologist Salary: What Does a Biologist Earn?

A “biologist salary” can vary widely depending on experience, sector (government, private, research), and location. The Australian Bureau of Statistics reports that full-time adult average weekly ordinary time earnings were $2,083.70 per week in May 2026. That equates to roughly $108,352 per year. Many professional biologists fall near or above this figure, especially those covered by awards such as the Professional Employees Award or the Health Professionals and Support Services Award.

For a biologist earning $45 per hour, the annual gross pay is $88,920. At $55 per hour, it becomes $108,680. These figures are before tax and super. You can compare your rate against the national minimum wage of $26.44 per hour, or check the relevant pay guides for your industry.

Award Rates vs. Minimum Wage

Most biologists are covered by an award or enterprise agreement, which sets minimum pay rates higher than the national minimum wage. The Fair Work Ombudsman publishes pay guides for each award. For example, the Health Professionals and Support Services Award includes classification levels for scientists. Always check your award to ensure you’re receiving at least the correct minimum rate.

Casual Loading and Superannuation

If you work as a casual biologist, your hourly rate should include a 25% casual loading on top of the base rate. Never enter a rate that already includes loading into the calculator; instead, use the base rate and tick the casual loading option. For the national minimum wage, the casual rate is $33.05 per hour.

Superannuation is paid on top of your gross pay. The super guarantee is 12% of your ordinary earnings, up to the maximum contribution base of $270,830 per year. For a biologist earning $88,920, the employer contributes an extra $10,670.40 into your super fund. This is not part of your take-home pay. See super and packaging for more details.

Tax and Take-Home Pay

Your annual gross pay is not what you take home. The Australian Taxation Office applies progressive tax rates for 2026–27:

Nil 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 is generally 2% of your taxable income. For a biologist earning $88,920, the estimated tax (including Medicare) would be around $19,500, leaving a take-home pay of about $69,420 per year.

Fortnightly Pay

Many employers pay fortnightly. To find your fortnightly gross, multiply your weekly pay by 2. For $45 per hour at 38 hours, weekly pay is $1,710, so fortnightly gross is $3,420. After tax, your fortnightly take-home would be roughly $2,670.

Using the Calculator

Our hourly conversion tool lets you enter your base hourly rate and see the annual, monthly, fortnightly, and weekly figures. It also estimates tax and super. Remember: the calculator assumes a consistent 38-hour week, no overtime, and no salary sacrifice. It’s a guide, not a binding determination.

For more detailed comparisons, refer to average pay data from the ABS or check the minimum wage page for the latest rates. If you’re a casual worker, see casual loading for how the 25% loading applies.

Final Thoughts

Understanding your biologist salary in annual terms helps you compare job offers and negotiate effectively. Always verify your award coverage and check the Fair Work Ombudsman’s pay guides for the most accurate rates. The formula is simple, but the context—tax, super, and loadings—makes the full picture clearer.
