Setting your day rate by feel — or by what you think clients will accept — is one of the most expensive habits in freelancing. Not because you're being ripped off, but because you're ripping yourself off.
The right approach is to work backwards from what you actually need to earn, then sense-check it against the market. Our interactive freelance calculator does exactly this — here's how the logic behind it works.
Why most freelancers undercharge
There are a few reasons this happens. The most common one is the salary comparison trap: you were on £50,000 as an employee, so £250/day feels like a lot because it "works out" to £65,000 a year. Except it doesn't — not once you account for the days you're not billing.
The second reason is fear. Quoting a higher rate feels like you're more likely to lose the work. Sometimes that's true. But it's also true that clients who push back hardest on rate are often the most difficult to work with, and the clients who are happy to pay a fair rate tend to be better ones.
The third reason is that nobody taught you the formula. So let's fix that.
The formula: work backwards from what you need
Your day rate isn't just your salary divided by 260 working days. That calculation ignores everything that makes freelancing different from employment.
Here's what actually needs to go into your number:
-
1
Start with your target annual income
What do you actually want to take home after tax? Work backwards from that. If you want £50,000 in your pocket, you need to gross roughly £70,000–£80,000 depending on your structure.
-
2
Subtract your non-billable days
You don't work 260 days a year. You take holiday. You get sick. You spend time on admin, pitching, and CPD. A realistic estimate is 20–30 non-billable days per year before you've even started.
-
3
Add a buffer for gaps between contracts
No freelancer is booked solid every week. A 15–20% buffer for time between clients is realistic, especially in your first year. That might mean 30–40 days a year where you're available but not earning.
-
4
Add your business costs
Software, accountancy, insurance, equipment, co-working space — these come out of your day rate, not on top of it. Add them up and divide by your billable days.
A worked example
Let's say you want to take home £55,000 after tax. Operating as a limited company, you'd need to gross around £78,000. Your annual business costs (accountant, software, insurance) come to about £3,500. And you're being realistic about billable days:
- 260 working days in the year
- Minus 25 days holiday
- Minus 5 days sick/admin
- Minus 40 days gap buffer (roughly 15%)
- = 190 billable days
Most people doing that calculation for the first time are surprised. It's higher than they expected. That's usually because they've been undercharging.
The UK average day rate for a mid-level freelancer in design, tech and marketing is roughly £350–£550/day. Senior specialists regularly charge £600–£900+. If your rate is significantly below those ranges and you have real experience, you're almost certainly undercharging.
How to sense-check your rate against the market
The formula tells you your floor — the minimum you need to charge to hit your financial goals. But the market sets the ceiling, and ideally you want to be somewhere in the middle of what clients in your sector expect to pay.
A few ways to calibrate:
- Talk to other freelancers. People are more open about rates than you'd think, especially in communities like Slack groups or at meetups. Ask peers what they charge.
- Look at job adverts for equivalent roles. If a senior designer role is paying £70,000 employed, a freelance day rate of £350–£450 is in the right ballpark.
- Check platforms like YunoJuno or Worksome for published rate ranges in your sector.
- Ask the client what budget they have before you quote. You'd be surprised how often they'll tell you — and it stops you quoting low when they were expecting to pay more.
What to do if your rate feels too high to say out loud
This is the real problem for most freelancers. The maths checks out, but quoting £450/day still feels awkward when you've been charging £300.
A few things worth remembering:
Clients aren't comparing you to employees. They're comparing you to the cost and hassle of hiring someone full-time, or to the other freelancers they've worked with. Your rate needs to feel reasonable in that context, not in the context of your old salary.
A higher rate often signals quality. Clients who have been burned by cheap freelancers before are sometimes actively reassured by a higher rate. It suggests you're established and serious.
You can increase gradually. If jumping to your correct rate feels too big a leap, raise it with new clients first. Keep existing clients at their current rate until contracts renew, then apply the increase. Most clients expect at least an annual increase.
"The day rate you're embarrassed to say is probably closer to your real rate than the one you've been defaulting to."
One more thing: review it every year
Your costs go up. Your experience grows. The market shifts. A day rate you set two years ago is almost certainly too low today — inflation alone has eroded it. Build in an annual review, ideally at the start of each tax year, and treat it like a pay rise negotiation with yourself.
If you're not sure where to start, the calculator below will show you the day rate you'd need to match a given salary — and what you'd actually take home once tax is factored in.
