Income Goals, Billable Hours & Tax Buffer
Freelance Required Hourly Rate Formula
Transparent mathematical methodology explained in plain English.
Hourly Rate = [ (Target Income / (1 - TaxRate)) + Annual Expenses + Profit Buffer ] / (Billable Hours × Weeks Worked)Converts your personal net take-home income goal into gross freelance revenue, adjusting for self-employment taxes, health insurance, non-billable overhead, and unbilled administrative hours.
Variables Explained:
- Target Income: Desired annual personal take-home pay after taxes and business expenses.
- Tax Rate: Estimated combined income and self-employment tax rate (typically 25%–35%).
- Annual Expenses: Business software, equipment, health insurance, legal, and accounting.
- Billable Hours: Realistic weekly hours spent directly on client projects (usually 25–35 hours).
$90,000 Target Take-Home with 30 Billable Hours/Week & 48 Weeks Worked
Calculating freelance rates with 25% tax and $12,000 annual overhead.
- Total annual billable hours = 30 × 48 = 1,440 hours.
- Pre-tax personal income needed = $90,000 / (1 - 0.25) = $120,000.
- Profit buffer (10%) = $120,000 × 0.10 = $12,000.
- Gross revenue needed = $120,000 + $12,000 (expenses) + $12,000 (buffer) = $144,000.
- Target Hourly Rate = $144,000 / 1,440 = $100.00 / hour.
- Day Rate (8 hrs) = $800.00; Monthly billing = $12,000 / month.
Câu Hỏi Thường Gặp (FAQ): Máy Tính Giá Theo Giờ Freelance
Click any question below to expand quick answers, formulas, and expert tips.
Why shouldn’t freelancers assume 40 billable hours per week?
Freelancers spend 20% to 35% of their working hours on non-billable administration: sales proposals, client onboarding, invoicing, bookkeeping, and marketing. Budgeting 25 to 30 billable hours provides a realistic baseline.
How much should I set aside for self-employment taxes?
In the US and many OECD countries, independent contractors pay both employer and employee portions of social security/medicare taxes in addition to income tax. A safe guideline is reserving 25% to 35% of net freelance earnings.
What should be included in annual freelance expenses?
Hardware (laptop, monitors), software subscriptions (Adobe, GitHub, Figma, accounting), health and dental insurance, co-working/home office costs, accounting fees, and professional education.
Should I quote hourly rates or project-based fixed fees?
While this calculator establishes your baseline hourly cost floor, quoting value-based fixed project fees is often more lucrative once you know your delivery speed and client value.
