Freelancer Day Rate Calculator
Work out what day rate you need to charge as a freelancer or contractor, or see what a given day rate could realistically earn you over a year.
How Your Working Year Breaks Down
Freelancer Day Rate Calculator UK
Our Freelancer Day Rate Calculator helps self-employed people, contractors and freelancers work out what to charge, or what a given day rate could realistically earn over a year. Unlike a simple pay conversion tool, it accounts for the things an employer normally absorbs on an employee’s behalf: unpaid holidays, sick days, admin time, business costs and a safety margin.
What Is a Freelance Day Rate?
A day rate is the amount a freelancer or contractor charges for a full day of work, typically used for project-based or contract work rather than hourly billing. It needs to cover not just your time, but everything a salaried employee’s pay packet indirectly includes: paid holiday, sick leave, pension contributions, insurance, equipment and the periods between contracts when there’s no billable work at all.
Why You Can’t Just Divide a Salary by Working Days
Employee salary and freelance revenue aren’t directly comparable. An employee earning £40,000 a year is paid that amount whether or not they’re at their desk every single day – holidays, bank holidays and sick leave are already built into their pay. A freelancer aiming for the same £40,000 has to earn it entirely from the days they actually bill a client, while still taking time off, doing admin, and covering their own business costs. Simply dividing £40,000 by 260 working days would significantly understate what needs to be charged per day.
Holidays and Bank Holidays
Freelancers don’t get paid annual leave, so every holiday day is a day of unbilled time that still needs to be accounted for somewhere in the rate. The same applies to bank holidays – if you don’t work them, they reduce your available billing days just as much as booked holiday does. The number of bank holidays varies across the UK: England and Wales typically have 8 a year, while Scotland and Northern Ireland observe a different set of dates and totals, so adjust the figure in the calculator to match where you work.
Sick Days and Buffer Time
Without employer sick pay, illness or unexpected downtime directly reduces your income unless you’ve planned for it. Building in a number of sick/buffer days – even if you don’t end up using them all – means an unplanned week off doesn’t blow a hole in your annual income.
Non-Billable Time
Not every working day is spent on billable client work. Freelancers typically spend a meaningful share of their time on things clients don’t directly pay for: quoting and proposals, invoicing and bookkeeping, marketing, finding new clients, admin, and professional development. This calculator lets you set that as a percentage of your available working days, so it’s factored into the rate rather than quietly eating into your income.
Business Expenses
Running as a freelancer or contractor comes with costs an employee doesn’t have to think about: software subscriptions, insurance, equipment, accountancy fees, phone and internet, and potentially home office costs. These need to be covered by your day rate before you’ve earned anything toward your actual income target.
Why Include a Safety or Contingency Buffer?
A safety/contingency buffer adds a percentage on top of your income and expenses target. It isn’t extra profit for its own sake – it’s an additional revenue margin to cover unexpected costs, downtime between contracts, and periods where your actual billable utilisation falls short of what you planned for. Even a modest buffer makes a rate noticeably more resilient over a full year.
Converting a Day Rate to an Hourly Rate
To convert a day rate to an hourly equivalent, divide it by the number of hours you typically work in a day. A £400 day rate over a 7.5-hour day works out to roughly £53.33 an hour – useful for comparing against hourly contract offers, though remember the day rate already has your non-billable time and expenses baked in, while a raw hourly comparison may not.
Working Backwards From a Day Rate
If you already know what day rate the market will bear, use “What could I earn at this day rate?” mode to see the annual, monthly and weekly revenue that rate could realistically generate once your actual billable days are accounted for – not the inflated figure you’d get by simply multiplying the day rate by 260.
Freelance Revenue vs Personal Take-Home Pay
This calculator deals entirely in gross freelance revenue – the money your business brings in before personal Income Tax, National Insurance, or how you choose to pay yourself (sole trader drawings or limited company salary/dividends). Your actual personal take-home pay will be lower once tax is applied. For that, use the Self Assessment Tax Calculator or National Insurance Calculator alongside this tool.
Why Real Income Depends on Consistent Billable Work
All of the figures here assume every billable day is actually sold to a client at your target rate. In practice, freelance income is rarely perfectly smooth – there can be gaps between contracts, slow months, or periods of part-time billing. Treat the results as a target rate and a useful benchmark, not a guaranteed annual income.
Frequently Asked Questions
How do I calculate my freelance day rate?
Work out your realistic billable days per year by subtracting annual leave, bank holidays and sick/buffer days from your total working days, then reducing further for non-billable admin time. Divide your target income plus business expenses plus a safety buffer by that billable-days figure. This calculator does that calculation for you in “What day rate should I charge?” mode.
What is a good freelance day rate?
There’s no single “correct” day rate – it depends on your industry, experience, location, market demand and personal income needs. This calculator won’t tell you what the market will pay, but it will show you the rate you personally need to charge to hit a given income target after accounting for time off, non-billable work and expenses.
How many billable days does a freelancer work per year?
It varies widely, but after accounting for holidays, bank holidays, sick/buffer days and non-billable admin time, many freelancers find their realistic billable days fall well below their total working days – often somewhere in the 150-200 day range on a standard working year, though this depends entirely on your own circumstances. Use the calculator’s breakdown to see your own figure.
Should freelancers charge for holidays?
Freelancers don’t typically invoice clients for holiday time directly, but the cost of taking unpaid leave needs to be built into the day rate charged on billable days. That’s exactly what subtracting annual leave and bank holidays from your available days achieves in this calculator.
How much should I allow for non-billable time?
This varies by how you work and how established your client base is. Newer freelancers spending more time on marketing and finding clients may need a higher percentage; those with steady, long-term contracts may need less. 15% can be a useful starting assumption, but adjust it to reflect your own circumstances.
What expenses should I include when calculating my day rate?
Typical freelance business expenses include software and subscriptions, professional insurance, equipment, accountancy fees, phone and internet, marketing costs, and a share of home office running costs if relevant. Include anything the business genuinely needs to pay for regardless of how much work comes in.
How do I convert a day rate to an hourly rate?
Divide the day rate by the number of hours in your working day. A £450 day rate over 7.5 hours is £60 an hour. This calculator shows the equivalent hourly rate automatically in both modes.
How much is a £500 day rate per year?
It depends entirely on how many days you actually bill. £500 x 260 working days would be £130,000, but that ignores holidays, bank holidays, sick days and non-billable time. Once realistic billable days are factored in, the actual annual revenue is typically significantly lower. Use “What could I earn at this day rate?” mode with your own assumptions to see a realistic figure.
Is freelance day rate the same as salary?
No. A day rate is gross business revenue for each billed day, out of which you still need to cover business expenses, unpaid time off, and personal Income Tax and National Insurance. A salary is normally quoted as a gross figure too – the amount before Income Tax, National Insurance and other deductions – with net salary being what’s actually received after those deductions. Either way, salary is a fixed amount an employer commits to paying regardless of day-to-day billing, which isn’t the case for freelance revenue. The two aren’t directly comparable without adjusting for these differences.
Does this calculator include income tax and National Insurance?
No. All figures in this calculator are gross freelance revenue before personal Income Tax and National Insurance. For an estimate of your tax position, use the Self Assessment Tax Calculator or National Insurance Calculator alongside this tool.
