The starting figures are placeholders, not market data: a take-home goal of £48,000, business costs of £3,200 and 65% billable time. Change them to match your situation.
Typical business costs for a web developer include IDE and cloud subscriptions, testing devices and hosting.
Worked example for a web developer in UK
With the starting figures above (£48,000 take-home, £3,200 costs, 22% tax, 65% billable, 40 hours a week, 6 weeks off), you would need about £64,738 in revenue a year. Across roughly 1,196 billable hours, that is about £54 an hour or £281 a day. If your billable share fell to 50% the hourly figure rises to about £70; at 80% it falls to about £44. These are illustrations of the formula, not market rates: replace every input with your own.
How web developers usually price work
Developers commonly work on hourly or day rates for ongoing work and fixed bids for tightly defined builds. Fixed bids carry risk, so many add a contingency and charge separately for discovery.
Where web developers lose money
- Fixed prices on projects with an unclear specification.
- Unpaid support after launch with no maintenance agreement.
- Absorbing third-party costs such as APIs, licences or hosting.
Write acceptance criteria, list what is out of scope, and agree how change requests are estimated and approved.
Tax and admin in UK
UK sole traders pay income tax plus Class 4 National Insurance on profits, filed through Self Assessment. Once turnover passes the VAT registration threshold (check the current figure on GOV.UK) you must charge VAT.
Remember to set aside money for the payment on account that can arrive in your first full tax year.
- Register as self-employed with HMRC and file a Self Assessment return each year.
- Payments on account can double your bill in the first year you owe tax, so a tax pot matters early.
- If you work through a client's systems, check IR35 rules for off-payroll working on GOV.UK.
Tax year: 6 April to 5 April. Authority: HMRC. Rules and thresholds change: confirm on the official site.
Questions
How much contingency should a web developer add to a fixed quote?
It depends on how well defined the work is. The calculator uses a 15% buffer as a starting point; raise it when requirements are vague or depend on third parties.
When do UK freelancers have to register for VAT?
When taxable turnover passes the VAT registration threshold. The figure changes, so read the current number on GOV.UK rather than relying on a copy elsewhere. You can also register voluntarily below it.
How the rate is calculated
Revenue needed = take-home income ÷ (1 − tax rate) + business costs. Billable hours = weekly hours × weeks worked × billable share. Hourly rate = revenue needed ÷ billable hours.
Why not just divide a salary by 2,080 hours?
An employee is paid for holidays, admin and downtime. A freelancer is not. Those hours still need to be covered by the hours you do bill.
Is the tax rate accurate?
No. It is a single flat estimate, because rules differ by country and income. Check with an accountant before you set prices.
