What to factor into your full-stack developer rate
Unbilled time
You can’t bill every working day. Holidays, public holidays, sick days and the admin, sales calls, proposals and learning between projects all eat into the year — most freelancers bill around 200 days, not 250.
Business overheads
Software, equipment and its depreciation, professional indemnity and public liability insurance, accounting, a workspace and marketing typically add 15–30% on top of the income you actually want to keep.
Pension and benefits
No employer is funding your pension, paid leave or sick pay any more. Replace them yourself by building a pension contribution and a cushion into the rate.
Tax and structure
UK freelancers usually work as a sole trader or through a limited company. for client engagements, IR35 status changes who pays employer national insurance — get a status determination in writing.
Profit and buffer
A 10–20% margin on top isn’t greed — it funds quiet periods, late payers, equipment replacement and growth. Without it you have a job, not a business.
How to justify your rate (without discounting)
- Lead with the outcome, not the hours — what does solving this problem as a full-stack developer actually earn or save the client?
- Anchor to the value of the project and the cost of getting it wrong, not to your old salary.
- Bring proof: relevant work, case studies, measurable results and testimonials that de-risk hiring you.
- Quote a fixed scope with clear deliverables so the conversation is about value, not a daily number.
- If price is a sticking point, reduce the scope — never your rate. Discounting trains clients to expect it.
- Charge a deposit and bill in stages so cash flow and risk stay balanced.

Freelance full-stack developer rates: FAQs
How much should a freelance full-stack developer charge in the UK?
A freelance full-stack developer in the UK typically works out around £525 per day, with most landing between £450 and £675. That benchmark is based on advertised contractor rates. Your own number depends on your target income, overheads and how many days you can bill — use the calculator above to set it.
What hourly rate does that work out to for a full-stack developer?
At a typical day rate of £525 and a 7.5-hour billable day, that is roughly £70 per hour. Charging by the day or by fixed project scope is usually better than hourly, because it ties your price to value rather than time.
How do I work out my freelance full-stack developer day rate?
Start from the income you want before personal tax, add the costs an employer used to cover (pension, overheads, paid time off), add a profit buffer, then divide by the days you can realistically bill in a year. The calculator above does exactly this and shows every step.
Should I charge a day rate or per project?
A day rate is easy to compare and good for open-ended or embedded work. Fixed-scope project pricing is usually better paid because it’s tied to the value delivered rather than time spent — but only quote it once the scope is clear. Use your day rate as the floor underneath any project quote.
How do I avoid underpricing myself as a full-stack developer?
Know your break-even rate — the point below which you’re working at a loss once costs and unbilled time are counted. The calculator flags it for you. If a client or platform pushes below it, walk away or cut scope; never accept work that loses you money.
