30% covers income tax plus the Medicare levy around the median full-time wage; remember super is your job now, not an employer top-up.

| Level | Hourly | Day rate | Project floor |
|---|---|---|---|
| Junior×0.7 | $115 | $875 | $4,375 |
| Mid-level×1 | $165 | $1,250 | $6,250 |
| Senior×1.4 | $230 | $1,725 | $8,625 |
Junior ×0.7 and senior ×1.4 income multipliers, consistent with typical published salary spreads. The project floor is one reserved week (5 × day rate) — the smallest engagement worth switching contexts for.
The calculation starts from the median full-time salary and adds what employment quietly includes. Overhead (25%) covers the costs an employer would carry — equipment, software, insurance, workspace, accounting. A tax set-aside (30%) is applied on top of income plus overhead. 30% covers income tax plus the Medicare levy around the median full-time wage; remember super is your job now, not an employer top-up.
hourly = ($110,000 + overhead + tax buffer) ÷ (46 weeks × 40 hrs × 60% billable) = $178,750 ÷ 1,104 hrs → $165/hr (rounded up to the nearest 5)
The divisor is the part most people get wrong. 60% billable time is a healthy, sustainable utilisation for an established freelancer — proposals, marketing, admin, and invoicing are real work that no client pays for. And 46 working weeks assumes six weeks of holidays, sick days, and quiet spells; freelancers who plan for 52 fund their time off with debt.
Senior freelance developers rarely bill hourly for whole projects — day rates and weekly retainers are the norm, and value-priced fixed bids win the highest effective rates.
