How to Calculate Your Freelance Day Rate in the UK

Why Guessing Is Expensive

A day rate set by intuition or industry gossip is usually wrong in one direction or the other. Too low, and you're working harder than you need to for income that won't support a sustainable business. Too high without the experience to back it up, and you lose work. Starting from your actual costs removes the guesswork.

Step 1: Work Out Your Annual Target Income

Start with what you need to take home after tax. Include your personal living costs (rent or mortgage, food, transport, bills), a reasonable savings buffer, and whatever you want beyond the basics. Be honest. Most people underestimate what they actually spend.

Let's say you need £35,000 in take-home income.

Step 2: Gross Up for Tax and National Insurance

That £35,000 is after tax. To know what you need to earn before tax, you need to work backwards through the tax calculation. At a rough level, a sole trader needing £35,000 net needs to earn approximately £47,000 to £50,000 in profit after expenses, depending on their specific situation.

Add your allowable business expenses on top of this figure. Typical expenses for a freelancer might be £3,000 to £5,000 a year. So your target gross turnover is around £52,000 to £55,000.

Step 3: Add Pension Contributions

If you want to save for retirement, add your target pension contribution to the gross figure. Even 5% of income is worth adding here, because it's money you need to earn before you can save it.

Step 4: Work Out Your Billable Days

A standard working year has around 260 working days. Subtract:

• Holiday (20 to 25 days is standard)
• Bank holidays (8 days)
• Sick days and contingency (5 to 10 days)
• Non-billable time: business development, admin, CPD (typically 20 to 30% of your working time)

A realistic billable day count for a solo freelancer is around 160 to 180 days per year. 200 is possible but leaves very little buffer.

Step 5: Divide Target Income by Billable Days

If your target turnover is £54,000 and you have 170 billable days, your minimum day rate is £54,000 / 170 = £318 per day.

This is your floor, not your ceiling. If the market rate in your sector is higher, charge the market rate. The calculation simply tells you the minimum below which you can't operate sustainably.

Hourly Rate from Day Rate

If clients ask for an hourly rate, divide your day rate by the number of hours in your working day. Most freelancers use 7 or 7.5 hours. At £318 per day and 7 hours, that's £45.43 per hour. You might round this to £45 or £50 depending on the context.

Revisit It Annually

Inflation, increased experience, and rising costs all mean your rate needs to go up over time. Review it every year and raise it. A 5 to 10 percent increase annually is modest and defensible. New clients will accept your current rate as normal; for existing clients, give a month's notice.
