How to Calculate Your Freelance Hourly Rate
The starting point is your desired take-home pay, not your gross income. Add back the income tax and National Insurance you will owe, then add your annual business expenses including software, equipment, insurance, accounting fees and marketing. This gives you the total annual revenue you need to generate. Next, calculate your available billable hours by starting with 52 weeks, subtracting holiday weeks, bank holidays, an allowance for sick days and the time you spend on non-billable activities such as admin, marketing, invoicing and business development.
Most freelancers find that only 60 to 70 per cent of their working time is directly billable to clients. A freelancer working 48 weeks per year, 8 hours per day, 5 days per week has 1,920 gross working hours. At 65 per cent utilisation, that gives 1,248 billable hours. Dividing your required annual revenue by these billable hours gives the hourly rate you need to charge. This figure is almost always higher than people expect, which is why so many freelancers struggle financially by underpricing their services.
Freelance Rates vs Employed Salaries
A freelancer charging 50 pounds per hour is not equivalent to an employee earning the same amount. An employer pays additional costs on top of salary, including employer NI contributions, pension contributions, holiday pay, sick pay, office space, equipment and training. These typically add 20 to 40 per cent to the base salary cost. A freelancer at 50 pounds per hour, after accounting for tax, expenses, holiday, non-billable time and pension provision, might take home the equivalent of a 35,000 to 40,000 pound salary.
When negotiating rates with clients, framing your hourly rate in the context of the total employment cost they would incur for a permanent hire helps justify what might initially seem like a high number. Additionally, freelancers bring flexibility, specialist expertise and no long-term commitment, which has tangible value for the client beyond the hourly rate comparison.
When to Raise Your Rates
If you are fully booked for more than three months ahead, regularly turning down work, or receiving no pushback on pricing from prospective clients, these are strong signals that your rates are too low. Raise your rates for new clients first while honouring existing agreements, and give current clients reasonable notice of any increase. Most established freelancers review and adjust their rates annually, at minimum keeping pace with inflation and reflecting their growing experience and expertise.
