Contractor Hourly vs Daily Rate Calculator Australia 2025-26

Contractors in Australia usually compare offers as either an hourly rate or a day rate. The fastest way to check the numbers is to use the Contractor Pay Calculator with your pay cycle, hours per day, work weeks, days off, GST setting, super setting and tax options.

This guide shows how to convert contractor day rate to hourly rate, compare hourly rate to day rate, and estimate the annual salary equivalent before you accept a contract.

Day rate to hourly rate formula

To convert a contractor day rate to hourly rate, divide the day rate by the billable hours in a standard day:

Day rate	Hours per day	Hourly equivalent
$600	7.5	$80.00
$750	7.5	$100.00
$900	8	$112.50

If a client quotes a $750 day rate and expects 7.5 billable hours, the hourly equivalent is $100. If the contract regularly stretches to 9 or 10 hours, the effective hourly rate drops, so clarify expected hours before comparing offers.

Hourly rate to day rate formula

To convert hourly rate to day rate, multiply the hourly rate by the expected billable hours:

Hourly rate	Hours per day	Day rate equivalent
$75	7.5	$562.50
$100	7.5	$750.00
$120	8	$960.00

Hourly contracts can be better when project scope changes often because every extra billable hour is paid. Daily contracts can be simpler when the work pattern is stable and the client wants a fixed daily budget.

Estimate the annual salary equivalent

The salary equivalent depends on how many weeks you realistically bill. A simple gross-income estimate is:

day rate x billable days per week x billable weeks per year

For example, $750 per day x 5 days x 46 billable weeks is $172,500 in gross contract income. That is not the same as an employee salary because a contractor may need to allow for unpaid leave, sick days, public holidays, professional insurance, accounting costs, equipment, training and business administration time.

The Contractor Pay Calculator lets you adjust total work weeks and days off so you can compare a contractor rate with an employee salary on a more realistic basis.

Allow for GST, super and tax set-aside

Contract rates can be quoted plus GST or including GST. If the rate includes GST, remove the GST component before comparing your actual income. If your contracting business is registered for GST, keep GST separate from your own earnings because it may need to be remitted through BAS.

Super is another important comparison point. Employees usually receive super on top of ordinary time earnings, while independent contractors often need to price retirement savings into their own rate. If you want a salary-equivalent comparison, test both "includes super" and "plus super" assumptions.

Tax set-aside matters because contractors may not have PAYG withholding taken from every payment. Put aside income tax, Medicare levy and any HELP/HECS repayment from each invoice or pay cycle so the gross contract rate does not feel larger than the eventual take-home amount.

Quick comparison example

Suppose you are comparing two offers:

Offer	Gross contract income before settings
$95 per hour x 7.5 hours x 5 days x 46 weeks	$163,875
$750 per day x 5 days x 46 weeks	$172,500

The day rate looks higher in this example, but the better offer depends on whether either rate includes GST, whether super is expected inside the rate, how many days are actually billable, and how much non-billable work you absorb.

Use the calculator before negotiating

Before you accept a rate, check:

Whether the quote is hourly or daily.
The expected billable hours in a day.
Whether the rate is plus GST or GST-inclusive.
Whether super is included, paid separately, or self-funded.
How many weeks and days off you should exclude from billable income.
Your likely tax set-aside for income tax, Medicare levy and study-loan repayments.

Then run the scenario in the Contractor Pay Calculator and compare daily, weekly, fortnightly, monthly and annual results before negotiating your final rate.
