Contractor Calculator Australia 2026 — Rate and Pay Guide
A contractor calculator converts between three numbers: an employee salary, a contract rate (hourly or daily), and the money that actually lands in your bank account. Give it one and it works out the other two, after super, unpaid leave, GST, income tax and running costs.
Most people search for a "contractor calc" at one specific moment. They've just been offered a day rate, or they're about to quote one, and they genuinely can't tell whether the number is generous or a pay cut wearing a nice suit. A $600 day rate sounds enormous next to a $120,000 salary. Strip out the forty-odd days a year you won't bill, the super nobody pays for you, and the GST that was never yours, and it's close to line-ball.
The trap is that most contractor calculators on page one of Google are British or American. They model IR35, dividend tax and 401(k)s. Run an Australian rate through one and the answer is wrong before you've finished typing. This guide covers the arithmetic that actually applies here — in Sydney, Melbourne, Brisbane or anywhere else you're invoicing from — and you can check your own numbers against Leadkit's free Australian tax and GST calculators as you read.

Key takeaways
- To match a $120,000 salary you need roughly $670–$765 a day, or $84–$96 an hour excluding GST — that's salary plus 12% super, spread across 220 billable days, then loaded for downtime and self-funded overheads.
- 220 billable days is the realistic ceiling, not 260. Four weeks annual leave, ten days personal leave and around eleven public holidays are days an employee gets paid for and a contractor does not.
- The Super Guarantee has been 12% since 1 July 2025. As a contractor you fund it yourself, so it belongs inside the rate rather than as a nice thought at tax time.
- GST registration is compulsory once your turnover reaches $75,000 a year. GST sits on top of your rate and is remitted to the ATO — it is never your income.
- "Limited company" is a British term; Australia's equivalent is a Pty Ltd. UK contractor limited company calculators model IR35 and dividend tax, neither of which exists here, so they give the wrong answer entirely.
- A useful rule of thumb: 62–71 cents in every ex-GST dollar you invoice ends up as take-home cash after income tax, the Medicare levy and business running costs — before you set anything aside for super.

What is a contractor calculator? {#what-is-a-contractor-calculator}
A contractor calculator is a tool that translates between salary, contract rate and take-home pay using current tax, super and GST settings. There are two distinct jobs hiding under the one search term, and knowing which one you need saves a lot of confusion.
Rate conversion answers "what should I charge?". It takes the salary you'd otherwise earn, grosses it up for super and unpaid leave, and spits out an hourly or daily figure. This is the calculation you want before you accept an offer or send a quote.
Pay calculation answers "what do I actually keep?". It takes a rate you're already charging and strips out income tax, the Medicare levy and business expenses to land on a net number.
Both matter, and they run in opposite directions. Quote using only the second one and you'll undercharge, because take-home maths never tells you what the downtime and the self-funded super are worth.
What contract rate replaces your salary? {#contractor-rate-table}
As a rough guide, an Australian contract rate needs to be 35–45% above the equivalent salary's hourly figure to leave you no worse off. Here's what that looks like across common salary bands, excluding GST.
| Equivalent salary | Salary + 12% super | Day rate (ex GST) | Hourly rate (ex GST) |
|---|---|---|---|
| $80,000 | $89,600 | $450 – $510 | $56 – $64 |
| $100,000 | $112,000 | $560 – $635 | $70 – $80 |
| $120,000 | $134,400 | $670 – $765 | $84 – $96 |
| $150,000 | $168,000 | $840 – $955 | $105 – $119 |
| $200,000 | $224,000 | $1,120 – $1,275 | $140 – $160 |
Methodology: each row takes the salary, adds the 12% Super Guarantee, divides by 220 billable days, then applies a 10–25% loading for unbilled admin, insurance, tools, software and the gaps between contracts. Hourly figures assume an 8-hour billable day. The tax, super and threshold settings are the same 2025–26 ATO values that sit inside Leadkit's own income tax calculator — this is Leadkit's tool, not neutral third-party research, and we've said so plainly.
This is a price indication only. Your accountant will confirm the final position after looking at your actual circumstances.
How does a contractor calculator work in Australia? {#contractor-calculator-australia}
An Australian contractor calculator has to handle four local settings that overseas tools get wrong: the 12% Super Guarantee, the $75,000 GST registration threshold, the ATO resident tax brackets, and the 2% Medicare levy.
The 2025–26 resident brackets are the backbone of every take-home figure below:
| Taxable income | Rate on that slice |
|---|---|
| $0 – $18,200 | Nil |
| $18,201 – $45,000 | 16% |
| $45,001 – $135,000 | 30% |
| $135,001 – $190,000 | 37% |
| $190,001 and above | 45% |
On top of that sits the Medicare levy at 2%, and the Medicare Levy Surcharge if your income clears $97,000 without private hospital cover. If you're carrying a HELP debt, repayments from 2025–26 are worked out on a marginal basis — 15% on the slice between $67,000 and $125,000, then 17% above that — rather than the old whole-of-income rate. Current figures are always on the Australian Taxation Office site.
Across the estimates generated through Leadkit's tax and fee calculators, the line people consistently forget isn't income tax — it's the super they used to receive without ever seeing it on a payslip.
How do you work out a contractor hourly rate in Australia? {#contractor-hourly-rate}
Take the salary you want, add 12% super, divide by 220 billable days, divide by your billable hours per day, then add 10–25% for overheads. That's the whole calculation, and it's the one a contractor hourly rate calculator runs behind the scenes.
Worked through with a $120,000 target:
- $120,000 + 12% super = $134,400 total package value
- $134,400 ÷ 220 billable days = $611 a day at bare parity
- $611 ÷ 8 hours = $76 an hour before overheads
- Add a 10–25% loading = $84–$96 an hour ex GST
The loading isn't padding. It covers professional indemnity and public liability insurance, your laptop and tools, accounting fees, software subscriptions, and the unbilled hours you spend quoting, chasing invoices and doing your BAS — the Business Activity Statement you lodge to report GST and PAYG instalments. If you'd like a sense of what the accounting side costs, Leadkit's accounting services fee calculator gives a quick indication.
Quoting a trade job rather than a professional day rate? The same logic applies but the inputs differ — our guide on how to price trade jobs in Australia walks through materials, margin and travel.
How do you turn an hourly rate into a day rate? {#contractor-day-rate}
Multiply your hourly rate by billable hours per day — usually 8 — and then decide whether the day is capped or open-ended. That second part is where contractors quietly lose money.
A day rate is a fixed price for a day's work. If the client's definition of "a day" is ten hours and yours is eight, your effective hourly rate drops 20% without a single word being said about it. Put the hours in writing.
Three things worth settling before you agree to a daily figure:
- What counts as a day. Eight hours is the Australian default. Anything past that should be pro-rata or overtime.
- Half days. Most contractors charge 60% of a day rate for a half day, because the travel and set-up don't halve.
- Minimum engagement. A one-day booking costs you the same admin as a three-month one. Many contractors set a two-day minimum.
Day rates suit clients because they're predictable, and they suit you because they stop the endless quarter-hour accounting. The risk sits entirely in scope creep, so define the day tightly.
What does a contractor cost compared with an employee? {#contractor-cost}
A contractor on $700 a day costs a business around $154,000 a year, while a $120,000 employee costs roughly $141,000 once super, payroll tax and workers compensation are added. The gap is smaller than most hiring managers assume, and it's the argument that wins you the rate.
| Cost component | $120,000 employee | Contractor at $700/day |
|---|---|---|
| Base salary or fees | $120,000 | $154,000 |
| Super Guarantee (12%) | $14,400 | Included in the rate |
| Payroll tax and workers comp (~5%) | ~$6,700 | Nil |
| Paid leave (6 weeks equivalent) | Included | Nil — you only pay days worked |
| Recruitment and onboarding | Amortised, ongoing | Per engagement |
| Approximate annual cost | ~$141,100 | ~$154,000 |
Indicative figures only — payroll tax rates and thresholds differ by state, and your accountant will confirm the actual position.
The 9% premium buys the client flexibility: no redundancy exposure, no leave liability on the balance sheet, and the ability to end the engagement at the end of a contract. That's what you're actually selling, and it's a perfectly reasonable thing to say out loud in a rate negotiation.
One caution: the arrangement has to be genuine. Labelling someone a contractor when the working relationship is really employment is sham contracting, and it's unlawful. The Fair Work Ombudsman sets out the tests, and the ATO applies its own personal services income (PSI) rules — which can attribute your company's income straight back to you personally if most of your earnings come from your own skills and you fail the results test.
Is there a contractor limited company calculator for Australia? {#contractor-limited-company}
No — and you don't need one, because "limited company" is a British structure that doesn't exist in Australian law. This is the single most common mistake in the contractor calculator search results.
In the UK, a contractor limited company calculator models IR35 status, corporation tax, and the salary-versus-dividend split that makes UK contracting worth structuring around. None of it applies here. Australia has no IR35, and franking credits mean the dividend arbitrage that drives UK contractor tax planning largely washes out.
Australian contractors have three realistic structures:
- Sole trader with an ABN. Simplest and cheapest. Business income is taxed at your personal marginal rate, and you're personally liable for the debts.
- Pty Ltd company. The closest thing to a UK limited company. Company tax is 25% for a base rate entity, but profits distributed to you are taxed at your marginal rate with franking credits attached, so the total tax is broadly similar. Costs a few thousand a year to run. Registration and ongoing obligations sit with ASIC.
- Trust. Used where there's genuine income to distribute across beneficiaries. PSI rules limit how useful this is for one-person contracting.
For most single-person contractors the structure changes the paperwork far more than the tax bill. Get advice before spending money on a company you may not need.
How does a contractor pay calculator work out take-home pay? {#contractor-pay-calculator}
It starts with invoiced revenue excluding GST, subtracts business expenses to get taxable income, then applies the ATO brackets and the Medicare levy. Here's the full path across common day rates, assuming 220 billable days and business running costs of about 8% of revenue.
| Day rate (ex GST) | Annual revenue | Taxable income | Tax + Medicare levy | Net cash | Per month |
|---|---|---|---|---|---|
| $500 | $110,000 | $101,200 | $23,172 | $78,028 | $6,502 |
| $600 | $132,000 | $121,440 | $29,649 | $91,791 | $7,649 |
| $700 | $154,000 | $141,680 | $36,594 | $105,087 | $8,757 |
| $800 | $176,000 | $161,920 | $44,486 | $117,433 | $9,786 |
| $1,000 | $220,000 | $202,400 | $61,266 | $141,134 | $11,761 |
| $1,200 | $264,000 | $242,880 | $80,292 | $162,588 | $13,549 |
Methodology: figures use the 2025–26 ATO resident brackets and the 2% Medicare levy, with private hospital cover assumed and no study loan. GST is excluded throughout, because GST you collect is never yours. Net cash is before you set anything aside for super — the concessional contributions cap is $30,000 for 2025–26, and personal deductible contributions reduce the taxable income figure in column three.
This is a price indication only. Your accountant will confirm your final position.
Two things the table makes obvious. The proportion you keep falls as you earn more, from about 71 cents in the dollar at $500 a day to 62 cents at $1,200 — that's the progressive brackets doing their job. And the jump from $500 to $600 a day adds nearly $14,000 to your pocket, which is the strongest argument going for spending an afternoon on your rate rather than your invoicing.
If you're registered for GST, add 10% on top of every rate above and set it aside the day it arrives. Our GST calculator guide covers the mechanics.
What do contractors get wrong when pricing a rate? {#common-mistakes}
The most expensive mistake is dividing a salary by 260 working days instead of 220 billable ones. It looks like a rounding error and costs about 18% of your income.
The others, in rough order of how much they cost:
- Treating GST as income. It isn't. It's the ATO's money passing through your account. Register once turnover hits $75,000 and quarantine it immediately.
- Forgetting PAYG instalments. After your first year of contracting the ATO asks for tax quarterly rather than annually. The year you transition can feel like paying tax twice.
- Skipping super entirely. Nobody makes you contribute, which is exactly why so many contractors don't. Modelling the gap on a super projection calculator is a sobering ten minutes.
- Never raising the rate. Contractor rates are re-set at each renewal, not by an annual review. The Australian Bureau of Statistics wage price and CPI series give you a defensible number to anchor the conversation.
- Under-insuring. Professional indemnity and public liability are often contractual requirements, and they belong in your overhead loading.
Frequently asked questions {#faqs}
Q: What day rate equals a $100,000 salary in Australia?
A: Roughly $560–$635 a day excluding GST. The maths: $100,000 plus 12% super is $112,000 of total package value, divided by 220 billable days gives $509 a day at bare parity, and a 10–25% loading for insurance, tools, admin and time between contracts lifts it into the $560–$635 band. The lower end assumes a long, stable engagement with minimal downtime; the upper end suits short contracts where you're carrying real gaps. Whichever end you land on, sanity-check what it leaves you after tax and super before you sign anything.
Q: How many billable days are there in a contracting year?
A: About 220. There are roughly 260 weekdays in a year, and a contractor loses the twenty days of annual leave, ten days of personal leave and eleven or so public holidays that an employee is paid for regardless. If you also expect a few weeks between contracts, model 200 rather than 220 — it's the difference between a rate that holds up and one that quietly doesn't.
Q: Do I need to register for GST as a contractor?
A: You must register once your turnover reaches $75,000 in a twelve-month period, and you can register voluntarily below that. Registering means adding 10% to every invoice, lodging a BAS, and claiming GST credits on business purchases. Voluntary registration is often worth it if your clients are businesses, since they claim the GST back and your rate reads the same to them either way.
Q: Is a contractor calculator accurate for tradies as well as consultants?
A: The salary-to-rate conversion works for any contractor, but tradies usually price by job rather than by day, so materials, travel and site time change the picture. If you quote fixed-price work, an embedded quote calculator on your website is more useful — Leadkit has ready-made ones across more than 200 calculators covering trades, construction and professional services.
Q: What's the difference between an ABN contractor and an employee?
A: An employee works in someone else's business under their direction; a contractor runs their own business and is paid for a result. The practical differences are that contractors invoice rather than receive a payslip, fund their own super and leave, carry their own insurance, and can generally delegate the work. The label on the contract doesn't decide it — the substance of the relationship does, and the Fair Work Ombudsman and ATO both apply their own tests.
Q: Should I charge more for a short contract than a long one?
A: Yes. A two-week engagement carries the same sales and onboarding cost as a six-month one, spread across a fraction of the billing. Most experienced contractors add 15–30% for engagements under a month, and are comfortable discounting slightly for anything beyond six months where the pipeline risk largely disappears.
Q: How much should I set aside for tax as a contractor?
A: Between 25% and 35% of your ex-GST revenue covers income tax and the Medicare levy for most contractors earning $100,000 to $200,000. At $154,000 of revenue the combined bill works out around 24% of what you invoice; at $264,000 it's closer to 30%. Add another 10% on top if you're not carrying private hospital cover and expect to pay the Medicare Levy Surcharge, and keep GST in a separate account entirely.
Q: Does the contractor rate include super?
A: It should. Unless your contract explicitly says otherwise, a contract rate is the total amount you're paid, and the 12% Super Guarantee that an employer would have paid on top of a salary is yours to fund. That's why the rate table above adds super to the salary before dividing by billable days rather than after. Be aware that some contracts — particularly through agencies — do specify super separately, so read the payment clause before you compare offers.
Ready to work out your contract rate?
Pricing a contract rate isn't complicated, but it is unforgiving. The difference between dividing by 220 and dividing by 260, or between remembering super and forgetting it, is the difference between a contract that pays better than the job you left and one that just feels like it does.
Run your number both ways: what you need to charge, and what you'd keep. If the two don't agree, the rate is wrong, not the maths.
