Calculate the minimum rate you need to charge to hit your income goal
Many freelancers set rates based on what they "feel comfortable" charging rather than what they actually need. This calculator works backwards from your financial reality: your income goal, your taxes, your expenses, and your actual available hours.
Remember: as a freelancer, you pay both the employee AND employer portions of payroll taxes (15.3%), health insurance, equipment, software, and unpaid time for marketing and admin. All of these need to be baked into your rate.
Start with your desired annual take-home income, then work backwards: add self-employment taxes (around 15.3% in the US), business expenses, and health insurance. Divide the total by your actual billable hours per year — not your working hours. Most freelancers bill only 60–70% of their working time; the rest goes to admin, marketing, and unbillable work. This calculator does all of this automatically.
A billable hour is time spent directly working on client projects that you can charge for. Non-billable time includes business development, invoicing, responding to emails, professional development, and time between projects. If you work 40 hours a week but only 25 are billable, your effective billing ratio is 62.5%. Most freelancers overestimate their billable ratio, which leads to undercharging.
Yes — significantly more. As a freelancer you receive no paid holidays, no sick pay, no employer pension contributions, no employer National Insurance or payroll tax contributions, no employer health insurance, and you cover all your own equipment and software costs. A freelancer earning the equivalent of a £50,000 salary needs to bill approximately £70,000–£80,000 to take home the same amount after taxes and expenses.
Build downtime into your rate calculation. Reduce your billable weeks by 4–6 weeks per year to account for client gaps, slow seasons, and time needed to find new work. It's better to price this in upfront than to find yourself unable to cover expenses during quiet periods. Use the "weeks worked per year" field in this calculator to model different scenarios.
Day rates are common in contract and consulting work, especially in tech, design, and finance sectors. They reduce the awkwardness of tracking exact hours and signal seniority. An hourly rate works well for smaller projects or when scope is unpredictable. To convert: multiply your hourly rate by 7–8 hours for a day rate. Many freelancers charge both depending on the project type.
A sustainable freelance rate must account for costs employees never see because their employer absorbs them: employer National Insurance contributions, pension contributions, accountancy fees, professional indemnity insurance, software subscriptions, and non-billable time spent on business development, admin, and training. Freelancers must also fund their own holiday, sick leave, and unpaid time between contracts.
A common mistake is dividing a target annual salary by 52 weeks × 40 hours. A full-time freelancer realistically bills 60–70% of available hours at best — the rest goes to overhead. Someone targeting £50,000 working 46 billable weeks at 28 billable hours per week needs roughly £310/day before tax and overhead, not the £240/day a naive calculation would suggest.
If your engagement meets HMRC's IR35 "disguised employee" criteria, you'll owe income tax and National Insurance as if employed — eliminating the tax advantages of operating via a limited company. This materially changes what rate you need to achieve a given take-home. Clients in the public sector and large private-sector companies are legally required to determine IR35 status before engaging you. Inside-IR35 engagements typically require a 15–25% rate premium to match the net income of an equivalent outside-IR35 contract at the same headline rate.

One of the most common miscalculations freelancers make is treating their day rate or hourly rate as equivalent to the rate an employee earns. They're not comparable, because employees receive benefits that freelancers fund themselves: paid holiday, sick pay, employer NI contributions, pension contributions, equipment, software, training, and time spent on non-billable work such as admin, marketing, and client acquisition.
A useful rule of thumb: to match the true compensation of an equivalent employee, a freelancer's rate needs to be roughly 1.5–2× the employee's day rate. The higher end applies when benefits are generous, when significant non-billable time is involved, or when work is intermittent with gaps between contracts.
Employees in the UK receive a statutory minimum of 28 days paid annual leave. When a freelancer takes a day off, they earn nothing. To build in equivalent paid leave, you need to calculate your rate based on billable days only — not calendar working days.
A typical freelancer working 48 weeks per year (accounting for 4 weeks of holidays) has approximately 240 billable days — and that's before accounting for sick days, public holidays, and the reality that even on working days, not every hour is billable. Client work typically accounts for 60–75% of a freelancer's working time, with the rest spent on administration, proposals, invoicing, and business development.
Running the numbers: if your income goal is £60,000 and you have 200 realistic billable days per year at 7 hours each, your effective billable hours are 1,400. Before tax and expenses, you need a rate of approximately £43/hour just to hit your income target — before adding tax, NI, equipment, and any pension contributions.
As a sole trader in the UK, you pay Income Tax and Class 4 National Insurance on profits. For 2025/26, Class 4 NI is 6% on profits between £12,570 and £50,270, and 2% above that. You also pay Class 2 NI (a flat rate, currently £3.50/week for 2025/26) if profits exceed the Small Profits Threshold of £12,570. Class 2 contributions count toward your State Pension entitlement.
Self-assessment tax returns are due by 31 January following the tax year end. You'll pay tax in two instalments (payments on account) in January and July, plus a balancing payment the following January. New freelancers are sometimes caught off guard by this — it's possible to owe 18 months of tax within your first two tax years. Setting aside 25–30% of every invoice for tax is the standard recommendation.
Operating through a limited company allows some tax efficiency — you can pay yourself a low salary (minimising NI) and take the remainder as dividends, which are taxed at lower rates than employment income. The 2023 corporation tax changes (small profits rate 19%, main rate 25% for profits over £250,000) reduced but did not eliminate this advantage.
The additional administrative burden of a limited company — annual accounts, Corporation Tax returns, Companies House filings — typically costs £1,000–£3,000/year in accountancy fees. Factor this into your rate calculation, and consider whether the tax saving justifies the overhead. For lower earners (under £30,000 profit), the saving is often minimal.
