Freelance Rate Calculator — Methodology

Step-by-step calculation

Set a sustainable freelance hourly rate from your income goal, business expenses, billable hours, and desired profit margin.

1. 1

   Set your annual income target

   Your desired take-home — before adding the tax buffer the calculator will remind you about.

2. 2

   Enter realistic billable hours per week

   Most experienced freelancers bill 20–25 hours per week, not 40. Be honest.

3. 3

   Add annual overhead and weeks off

   Software, equipment, insurance, accountant fees — plus 5–8 weeks for holidays and sick days.

4. 4

   Set your desired profit margin

   10–20% above the floor is typical. This is your buffer for slow months.

5. 5

   Read minimum and recommended rates

   Quote at or above the recommended rate. Treat the minimum as the floor, not the target.

Assumptions and overrides

Tax-buffer guidance reflects each region's typical self-employment tax burden. US 25–30% (SE tax + federal + state), UK 20–30% (income tax + Class 2/4 NI), SA 25–35% (provisional tax). Verify against your individual situation.

Every region default on the calculator is editable. If your effective rate, fee, or threshold differs from the headline figure shown, type your own number into the field — the calculator recomputes instantly without leaving this page.
