How to Calculate Your Freelance Hourly Rate
The biggest mistake new freelancers make is taking their old corporate salary and dividing it by 2,080 hours (40 hours x 52 weeks). This mathematically guarantees failure because it ignores self-employment taxes, business overhead, vacation time, and the reality of unbillable hours.
The Mathematical Formula Used
To find a sustainable rate, you must work backward from your true costs, add a buffer for profit (so your business can grow), account for heavy taxation, and divide by realistic working hours.
Gross Revenue = (Costs + Profit Margin) / (1 - Tax Rate)
Hourly Rate = Gross Revenue / (Weekly Billable Hours × Weeks Worked)
A Quick Practical Example
Let's say you need $3,000/mo to live, and your software subscriptions cost $500/mo. Your base annual cost is $42,000.
- You want a 20% profit margin to save for a house. (Target: $52,500)
- You will pay roughly 25% in taxes. (Gross Target: $70,000)
- You want 4 weeks of vacation, working 48 weeks.
- You spend half your week doing admin, so you only have 25 billable hours a week.
- Total billable hours: 1,200/year.
- Result: $70,000 / 1,200 = $58.33 / hour.
If you charged $25/hr based on your old job, you would quickly go out of business.
