How to Calculate Your Freelance Profit Margin
Your freelance profit margin tells you what percentage of your revenue you actually keep as income. It's the single most important number for understanding your freelance business health.
The formula is simple:
Profit Margin = (Revenue - All Costs) ÷ Revenue × 100
But "all costs" is where most freelancers get it wrong. You need to include:
- Business expenses — software, equipment, office costs, travel, insurance
- Income Tax — based on your taxable profit (revenue minus allowable expenses)
- National Insurance — Class 2 (£3.45/week) and Class 4 (6% on £12,570-£50,270, 2% above)
- Pension contributions — unlike employees, no one contributes for you
- Student loan repayments — if applicable
What's a Good Freelance Profit Margin?
For UK service-based freelancers (designers, developers, writers, consultants):
- 60%+ = Excellent — You're running a highly efficient business
- 50-60% = Good — Healthy and sustainable
- 40-50% = Average — Room for improvement
- Below 40% = Warning — You may need to raise rates or cut costs
Freelancers with physical products or significant material costs will naturally have lower margins — aim for 25-40% in those cases.
5 Ways to Improve Your Freelance Profit Margin
- Raise your rates — Even a 10% increase goes straight to your bottom line. Use our Day Rate Calculator to benchmark.
- Claim all allowable expenses — Many freelancers miss legitimate deductions. Read our complete guide to freelancer tax deductions.
- Use the trading allowance — If your expenses are under £1,000, the trading allowance may be simpler.
- Move to value-based pricing — Charge based on outcomes, not hours. Higher margins with less work.
- Audit subscriptions quarterly — Software costs creep up. Cancel anything you haven't used in 60 days.
