Australia Contractor Day Rate Calculator

Moving from permanent to contracting needs roughly a 25%-30% rate premium just to break even, once you account for unpaid leave, self-funded super and the lack of job security. A A$150,000 base salary works out to about $885/day as a sole trader. Enter your own numbers below, or flip it around to see what a day rate is worth in permanent salary terms.

A modelling tool, not a quote. The contractor loading is a market rule of thumb (15%-20% PAYG/agency, 25%-35% sole trader) for unpaid leave, insurance, admin overhead and bench time; actual rates depend on skills demand, contract length and negotiating leverage. Uses the FY26/27 12% Super Guarantee rate and 10% GST. Not personalised financial or tax advice.

How to calculate your Australian day rate

Start from the "rule of 220 billable days": a standard working year has 260 days (52 weeks x 5 days), but you don't get paid for all of them as a contractor. Subtract 20 days of annual leave (about 7.7% of the year), 10 public holidays (about 3.8%, though this ranges 10-13 depending on your state), and 10 sick or carer's days (another 3.8%), and you land at roughly 220 billable days, before accounting for any gaps between contracts.

From there, your rate needs a loading on top of the equivalent permanent salary to cover what a permanent employee gets for free: paid leave, superannuation, insurance, equipment and job security. Multiply your target base salary by your loading factor, then divide by your billable days. A sole trader carrying their own insurance, accounting and self-funded super typically needs a 25%-35% loading; a contractor on PAYG or labour-hire agency payroll, where the agency already pays super, workers' compensation and payroll tax, generally only needs 15%-20% to cover the unpaid-leave gap.

Understanding superannuation and GST for contractors

Superannuation

Whether your day rate includes the 12% Super Guarantee depends entirely on how the contract is worded. "Plus super" means super is paid on top of your quoted rate; "inclusive of super" means it comes out of it. The difference is worth well over 10% of your annual income, so always clarify which basis a rate is quoted on before comparing offers. The calculator above shows both figures for every quote.

GST

You must register for GST once your annual turnover reaches $75,000, which most full-time contractors cross quickly. Once registered, you add 10% to your invoices; that GST passes through to the ATO rather than being extra income, but registration also lets you claim GST credits on business expenses like equipment and software. Below the threshold, registering is optional.

Frequently asked questions

1

What is a good contractor loading percentage in Australia?

25% to 30% is standard for sole traders and independent contractors, to compensate for unpaid leave, self-funded super, insurance and the lack of job security. If you're paid through a recruitment agency on PAYG payroll, the agency already handles super, workers' compensation and payroll tax, so a lower 15%-20% loading is enough since it only needs to cover unpaid leave.

2

How do I calculate my day rate from my current salary?

Multiply your target base salary by your contractor loading factor (1 plus your loading %), then divide by your realistic billable days for the year (220 is a common default). For example, a A$150,000 base salary with a 30% sole trader loading over 220 billable days works out to roughly $885/day. The calculator above runs this for your own numbers, plus the reverse: enter a day rate to see the permanent salary it's equivalent to.

3

How do I convert my daily rate to an hourly rate?

Divide your day rate by your standard billable hours per day, typically 7.5 or 8 hours. A A$800/day rate at 7.5 hours works out to roughly A$107/hour; at 8 hours it's A$100/hour. Most Australian contracts bill by the day rather than the hour, so this is mainly useful for comparing against hourly-rate roles or part-day engagements.

4

Does a contractor day rate include superannuation?

It depends entirely on how the contract is worded. Recruitment agency contracts often specify "day rate + super" (super is paid on top) or "day rate inclusive of super" (the 12% Super Guarantee comes out of the quoted rate). Always confirm which basis you're being quoted before accepting a rate, since the difference is worth over 10% of your annual income. The calculator shows both figures so you can compare rates quoted either way on a like-for-like basis.

5

Do I need to charge GST on top of my day rate?

You must register for GST once your annual turnover reaches $75,000, which most full-time contractors will cross well within a year. Once registered, you add 10% GST to your invoices on top of your rate; you collect it from the client and remit it to the ATO (it isn't extra income for you), but you can also claim GST credits back on business expenses. Below the threshold, registration is optional.

6

What's the difference between a sole trader and a PAYG agency contractor?

As a sole trader or independent contractor, you invoice clients directly, handle your own public liability and indemnity insurance, pay your own accounting costs, and fund your own super, so your loading needs to be higher (25%-35%). On PAYG or labour hire agency payroll, the agency runs you through their payroll, pays the 12% Super Guarantee, workers' compensation and payroll tax on your behalf, and you're taxed like an employee on each pay run, so a smaller 15%-20% loading is usually enough to cover just the unpaid leave gap.

7

Why is the standard billable-day year only 220 days, not 260?

A full Australian working year is 260 days (52 weeks x 5 days), but a contractor doesn't get paid for all of them. Subtract 20 days annual leave, 10 public holidays (this varies 10-13 by state), and 10 sick or carer's days, and you land at roughly 220 billable days. Many contractors also budget extra downtime for gaps between contracts, which is why the calculator lets you adjust billable days from 200 to 230 depending on how much bench time you expect.

8

Is there a superannuation cap I should know about as a high-earning contractor?

Yes. The ATO sets a Maximum Super Contribution Base per quarter, above which an employer isn't required to pay the 12% Super Guarantee on the excess. It only applies to employees and PAYG-payroll contractors above roughly A$260,000/year equivalent; independent sole traders billing direct aren't bound by it and can choose to contribute more or less to their own fund as they see fit.
