Hourly Rate Calculator Australia | Free & Accurate for Professional Services
For Australian consultants, accountants, lawyers, designers and advisers who bill for expertise and need a defensible rate that reflects real utilisation.
Last updated 31 May 2026
Professional services firms live and die by the gap between the rate they charge and the hours they can actually bill, and this hourly rate calculator makes that gap visible. Whether you are a sole consultant, a small accounting practice or a boutique advisory firm, your true cost per billable hour is far higher than headline salary divided by 38 hours. Non-billable time dominates: business development, proposals, internal meetings, professional development to maintain CPD or CPE requirements, and the administrative drag of timesheets and invoicing. Add professional indemnity insurance, practising certificates, professional body memberships, premium software and an office, and your overheads climb quickly. This tool works backwards from the income and profit you want, layers your real overheads on top, and divides by genuinely billable hours, so you set a rate that survives a low-utilisation month rather than one built on wishful thinking.
How to use this tool
- 1
Enter your target annual income
Use the take-home figure you want before income tax but after business costs. Be honest: include enough to cover super you pay yourself (11.5% in 2025-26) and a buffer for slow months.
- 2
Add overheads and realistic billable hours
Total your annual overheads (software, insurance, accountant, vehicle, tools) and enter how many hours you can genuinely bill per week, not the hours you sit at the desk.
- 3
Set working weeks and read your rate
Subtract annual leave, sick days and public holidays from 52 weeks. The calculator instantly shows your recommended hourly rate, day rate and annual billable hours.
Why your hourly rate is never just income divided by hours
The single biggest mistake Australian sole traders make is dividing their desired income by a full working week. If you want $90,000 and assume 38 hours across 52 weeks, you land near $46 an hour and quietly go broke. Two realities break that maths. First, you cannot bill every hour. Quoting, invoicing, chasing payment, marketing, bookkeeping and travel are real work but no client pays for them, so genuinely billable time is often 50 to 65 percent of your week. Second, your business has costs the rate must absorb: public liability and professional indemnity insurance, accounting software like Xero or MYOB, your accountant, phone and internet, tools, a vehicle, and professional registration or memberships. A good hourly rate calculator folds both into one number. This tool starts from the income you actually want to keep, adds your overheads back on top, then divides by the hours you can truly bill across the weeks you actually work. The result is usually 40 to 80 percent higher than the naive figure, and it is the rate that keeps you solvent rather than busy and broke.
GST, super and tax: what your rate has to cover in Australia
Your hourly rate sits on top of several Australian obligations, so treat the calculator output as your ex-GST price. Once your turnover passes the $75,000 GST threshold you must register for GST and add 10 percent on top of your rate. That GST is not yours; you collect it and remit it to the ATO each BAS, so never bank it as income. Income tax then applies to your profit, not your revenue, which is why entering a realistic overheads figure matters: every legitimate deductible cost lowers the tax base. Superannuation is on you. As a sole trader you are not paid super by anyone, so to match an employee you should build at least 11.5 percent (the 2025-26 rate, rising to 12 percent from 1 July 2025) into your target income and contribute it yourself, claiming the deduction. Set aside roughly 25 to 30 percent of profit for income tax in a separate account so the annual or quarterly bill never blindsides you. Quoting and budgeting against the Australian financial year (1 July to 30 June) keeps your rate reviews, super contributions and tax planning aligned. Review the rate at least once a year as your costs and demand shift.
Billable hours: the number that quietly sets your income
Annual billable hours is the lever most people get wrong, and this calculator makes it visible. Start at 52 weeks, then subtract four weeks of annual leave, two weeks for sick days and quiet periods, and the roughly two weeks lost to Australia's public holidays once you spread them across the year. That leaves about 44 working weeks. Now apply a billable ratio. A consultant doing deep client work might bill 25 to 30 hours of a 40-hour week; a tradesperson on the tools might bill 30 to 35 but lose hours to travel and quoting. Multiply realistic weekly billable hours by working weeks and you get your annual billable hours, the denominator that decides everything. The trap is optimism: assume 38 billable hours over 52 weeks and your rate looks low and your income vanishes. The fix is conservatism. If you bill more than planned, you simply earn a buffer. Track your actual billable ratio for a month using a timer or your accounting software, then feed the real number back in. Most people are shocked by how low it is, and how much that single correction lifts the rate they should be charging.
From a one-off calculation to a quoting system that pays for itself
Working out your rate once is the easy part. The harder, more valuable work is applying it consistently: pricing every quote with current overheads, tracking billable versus unbillable hours so the ratio stays honest, flagging when overheads creep, and reviewing the rate each financial year. Most sole traders do this in a spreadsheet they update twice and then abandon, which is exactly when underpricing creeps back in. That is the kind of repetitive, rules-based admin that automation handles well. At Clever Ops we help Australian businesses connect their quoting, time tracking and accounting tools so the right rate flows into every quote automatically, overheads update in the background, and you get a prompt when it is time to review. If your pricing lives in your head or a stale spreadsheet, that is a bottleneck worth removing. Book a Free Assessment and we will map where your quoting and admin time is leaking, then show you what can be automated.
Utilisation, leverage and rate-setting in Australian professional services
In professional services the word that decides profitability is utilisation: the share of your available hours you actually bill. Even strong consultants and advisers rarely exceed 70 to 75 percent, and many sit closer to 55 to 60 percent once business development, CPD, proposals, internal admin and recovery from non-paying scope creep are counted. The professional bodies make this worse in the right way: CPA Australia, CA ANZ, the Law Society and similar require ongoing professional development hours that are essential but unbillable. Feed an honest billable figure into the calculator and your required rate jumps, which is precisely the point, because clients in this sector buy outcomes and credibility, not the lowest hourly number. Your overheads list should include professional indemnity insurance (often mandatory to practise), a practising certificate or registration, professional membership fees, premium research and practice-management software, and any office or staff costs. If you employ junior staff, remember their charge-out rate funds their salary plus on-costs including the 11.5 percent superannuation guarantee rising to 12 percent from 1 July 2025, payroll tax once you cross your state threshold, leave loading and supervision time. Once you have a defensible rate, consider productising it as fixed-fee packages or retainers; clients value the certainty, and you escape the trap of selling hours. Review every financial year against rising insurance and salary costs so your margin does not quietly erode.
Worked example
Mara is a freelance UX designer in Brisbane who recently went out on her own. She wants to know what to charge so she keeps a healthy income after costs.
- Target annual income
- $95,000
- Annual business overheads
- $18,000
- Billable hours per week
- 26
- Working weeks per year
- 45
Recommended hourly rate: $97/hr (ex-GST) | Equivalent day rate: $773 | Annual billable hours: 1,170
Mara needs $113,000 total ($95,000 income plus $18,000 overheads) across 1,170 billable hours, giving roughly $97 an hour before GST. Note how low her billable hours are: 26 a week over 45 weeks, not the 38 by 52 she first assumed. Had she used that optimistic figure, her rate would have looked like $57 and left nothing for super or tax. Once registered for GST she invoices clients $107 an hour, remitting the $10 to the ATO.
Who uses this tool
Solo management consultant
An ex-corporate strategy consultant assumes their $180,000 salary translates to a simple hourly figure, but the calculator with a realistic 22-hour billable week and full overheads reveals they need to charge $260 an hour to match it, reshaping how they price retainers.
Small accounting practice principal
A practice owner sets associate charge-out rates by entering each staff member's target contribution, salary on-costs including super and payroll tax, and a 65 percent utilisation assumption, producing rates that genuinely cover the cost of the team rather than guesswork.
Boutique law or advisory firm
A two-partner advisory firm uses the day rate output to move from time-based billing to fixed-fee project pricing, giving clients budget certainty while protecting the firm's margin against scope creep on complex engagements.
Frequently asked questions
How is my recommended hourly rate calculated?
The calculator adds your target annual income to your annual business overheads, then divides that total by your annual billable hours (billable hours per week multiplied by working weeks per year). This works backwards from what you need to earn and spend, rather than guessing a rate, so the figure genuinely covers your costs and the income you want to keep before income tax.
Should I add GST to the rate this calculator gives me?
Yes, if you are registered for GST. The output is your ex-GST rate. Once your turnover passes the $75,000 threshold you must register and add 10 percent on top when invoicing. That GST is collected for the ATO and remitted at BAS time, so never treat it as part of your income or your hourly rate.
Does the calculator account for superannuation?
Not automatically, because sole traders pay their own super. The cleanest approach is to build at least 11.5 percent (the 2025-26 rate) into your target annual income figure, then contribute that to your fund yourself and claim the deduction. That way your hourly rate generates enough to fund retirement the same way an employer would.
How many billable hours should I actually enter?
Enter the hours you can genuinely invoice, not the hours you work. Most sole traders bill only 50 to 65 percent of their week once quoting, admin, marketing and travel are removed. A 40-hour week often yields 24 to 30 billable hours. Underestimating here is safer than overestimating, which inflates your hours and pushes your rate too low.
How many working weeks should I assume per year?
Start at 52, then subtract about four weeks of annual leave, two weeks for sick days and quiet periods, and roughly two weeks for Australian public holidays. That leaves around 44 working weeks. Adjust for your own situation: someone taking minimal leave might use 46 to 48, while a parent or seasonal worker may use fewer.
How often should I recalculate my hourly rate?
At least once each Australian financial year, ideally in May or June before 1 July, so your new rate aligns with rising super rates, insurance renewals and software price increases. Recalculate sooner if your overheads jump, your billable ratio changes, or demand for your work outstrips your capacity, which is a clear signal to raise prices.
