How the engine works

SoleTraderTax uses a 4-step sole trader pricing engine. Here's exactly how your charge-out rate is calculated.

1

Step 1

Reverse ATO Tax Calculation

Most tools calculate tax on a gross income. SoleTraderTax works backwards: given your desired take-home, it solves for the pre-tax income that, after ATO progressive brackets and Medicare levy, produces exactly what you want. This is done via binary search accurate to within $1.

Step 2

Add Business Overheads

Your charge-out rate must recover all business costs: vehicle, tools, insurance, software, marketing, and miscellaneous. These are annualised and added to your required taxable income to get total required revenue.

Step 3

Realistic Sole Trader Billable Hours

Sole traders don't bill 38 hours a week. Quoting, admin, travel, chasing payments, and quiet periods typically reduce billable hours to 20–25 per week. The default of 25 hrs × 46 weeks = 1,150 billable hours per year reflects this reality.

Step 4

Required Charge-Out Rate

Required revenue ÷ annual billable hours = your minimum charge-out rate. The calculator also shows a Minimum Safe rate (−10%) and a Premium rate (+15%) to give you a negotiating range.
