Calculate your minimum viable rate by dividing your gross income target (net income needed plus approximately 35-40% for tax and NI) by your annual billable hours (typically 60-70% of working hours). Research market rates for your skill level and sector. Most freelancers undercharge when starting — often by 20-40%. A project rate based on value delivered is frequently more lucrative than a day rate. Review rates at minimum annually.
Pricing is the part of freelancing that most people find most uncomfortable — and the part that has the largest single impact on whether the business is financially sustainable. Setting rates too low leaves you overworked and underpaid; setting them too high without clear communication of value loses work you could have won. Here is a methodology based on real numbers rather than guesswork.
Step One: Calculate Your Floor Rate
Before researching market rates, understand what you need to earn to make the business viable:
- Set your target net (take-home) income — include all personal costs and savings.
- Gross up for tax and NI: add approximately 35-40% to convert net income to gross (varies by income level — get your accountant to calculate your specific position).
- Estimate annual billable hours: from your total working days (typically 220-230/year), subtract time for admin, marketing, professional development, and holidays. Most freelancers bill 55-65% of working time. At 220 days × 7 hours × 60%: approximately 924 billable hours/year.
- Divide gross income target by billable hours.
Example: target take-home £45,000. Gross income needed at 38% tax/NI: approximately £63,000. Divided by 924 billable hours: minimum hourly rate approximately £68/hour.
This is your floor. Market research determines where above this floor you can price.
Step Two: Research Market Rates
Sources for market rate data:
- Industry salary surveys converted to day rates (multiply annual salary by approximately 1.5-2× to account for self-employment costs and lack of benefits)
- Freelancing forums and community rate surveys
- Recruiters placing contractors in your field — they have clear market benchmarks
- Job boards listing day rates for similar contract roles
- Peers in your network — many freelancers will share rates in trusted communities
Rates vary significantly by specialism, experience, sector, and geography. London rates typically run 20-30% above equivalent work elsewhere.
Choosing Your Pricing Model
Day rate
Standard for consulting and contract work. Transparent and easy for clients to compare. Risk: scope creep where you do more than a day's work for a day's pay.
Project rate
You charge a fixed price for a defined deliverable. Rewards efficiency — complete it in less time, earn more per hour. Requires precise scope definition to avoid unpaid overruns. Preferred by experienced freelancers because it decouples income from time.
Retainer
Recurring monthly payment for a defined scope of ongoing work. Provides income predictability for you and priority access for the client. Usually involves some discount versus pure day-rate billing in exchange for the certainty.
The Undercharging Trap
Most new freelancers charge less than their market-rate peers — sometimes by 30-50%. The underlying logic — "lower rates win more work" — is partially true but creates persistent problems: attracting price-sensitive clients who are often the most demanding, an inability to invest in development that would justify higher rates, and permanent psychological difficulty raising rates with established clients.
A more effective approach: set rates based on your calculation and market research, communicate them with confidence, and accept that some prospects will not engage at your rates. The clients who don't engage at your rates generally aren't the most valuable clients anyway.

Frequently Asked Questions
How often should I raise my rates?
Review annually at minimum. Inflation alone justifies regular increases. As your experience, skills, and reputation develop, rates should increase materially. Give existing long-term clients advance notice (4-6 weeks) and frame increases in the context of your development and market conditions.
Should I charge the same rate to all clients?
Not necessarily. Large corporate clients often have larger budgets and higher expectations of quality and professionalism — pricing to reflect this is reasonable. Clients requesting quick turnaround, unusual working hours, or work outside your normal scope may warrant premium rates.
