6.4 - Tax-Integrated Pricing: What Margin Do You Need?
Most beauty workers set prices by looking at what other people charge and picking a number that feels right. That's not pricing - that's guessing. And it's why so many self-employed beauty professionals work flat out and still can't figure out where the money goes. This guide works backwards from the take-home pay you actually want, adds every cost and tax you'll face, and tells you what you need to charge per treatment to hit your target. The numbers might surprise you.
Quick rule of thumb: if your average treatment price is below £41, you're almost certainly not hitting £30,000 take-home. Do the maths before you set another price.
Tip for new starters: Do this calculation before you set a single price. Most new beauty workers guess their prices, then spend months wondering why they're broke. Thirty minutes with a calculator now saves you a year of working for less than minimum wage.
The problem with copying other people's prices
When you set your prices based on what others charge, you're assuming:
- Their costs are the same as yours (they're not)
- They've done the maths (most haven't)
- They're earning a decent living (many aren't)
- Their business model is the same as yours (it isn't)
The nail tech down the road charging £25 for a full set might be working from her mum's spare room with no rent, no insurance, and no idea she owes HMRC £3,000. Copying her prices means copying her mistakes.
The only way to price properly is to start with what you want to earn, add everything that sits on top of it, and work out what you need to charge to make the numbers work.
Worked example: "I want to take home £30,000"
Let's build this from the ground up. £30,000 take-home (net profit after all business costs and tax) is a reasonable starting target for a sole trader. It's not luxury money - it's a modest living. Let's see what it takes to get there.
Step 1: Your personal tax and NI
These figures are based on 2025/26 tax year rates and thresholds. Your actual figures may differ slightly - check with your accountant.
| Tax / NI | How it works | Amount on £30,000 profit |
|---|---|---|
| Income tax | Personal allowance: £12,570 (0%). Basic rate: 20% on £12,571-£50,270. | £30,000 - £12,570 = £17,430 x 20% = £3,486 |
| Class 4 NI | 6% on profits between £12,570 and £50,270 (2025/26 rate) | £17,430 x 6% = £1,046 |
| Class 2 NI | Flat rate ~£3.50/week (2025-26 rate) (voluntary from 2024/25, but worth paying for state pension credits) | 52 x £3.50 = £182 (2025-26 rate) |
Total tax and NI on £30,000 profit: ~£4,711
So to take home £30,000, you need to earn at least £34,711 in profit (after business expenses, before tax).
But that's profit after expenses. Now let's add the expenses.
Step 2: Your business costs
These are typical annual costs for a self-employed beauty professional. Your actual costs will vary - adjust the numbers to match your situation.
| Cost | Monthly | Annual |
|---|---|---|
| Chair rent / room rent | £800-1,000 | £10,400 |
| Products and consumables | £200 | £2,400 |
| Insurance (public liability + professional indemnity) | £25 | £300 |
| Accountant / bookkeeping | £42 | £500 |
| CPD / training courses | £42 | £500 |
| Phone, WiFi, marketing | £50 | £600 |
| Booking software | £25 | £300 |
| Equipment replacement / maintenance | £25 | £300 |
| PPE and laundry | £15 | £180 |
| Miscellaneous (parking, printing, waste disposal) | £20 | £240 |
Total annual business costs: ~£15,720
Step 3: Add it all up
| Component | Amount |
|---|---|
| Take-home pay (your target) | £30,000 |
| Income tax | £3,486 |
| Class 4 NI | £1,046 |
| Class 2 NI | £182 |
| Business costs | £15,720 |
| Total gross revenue needed | £50,431 |
To take home £30,000, you need to bring in approximately £50,431 in revenue. That's your annual turnover target.
Step 4: What does that mean per treatment?
Now divide by the number of treatments you can realistically do in a year.
Working days: 48 weeks (4 weeks off for holidays, sickness, and quiet periods) x 5 days = 240 working days.
Treatments per day: Realistically, 4-6 depending on service length. Let's use 5.
Total treatments per year: 240 x 5 = 1,200 treatments
Minimum average price per treatment: £50,431 / 1,200 = £42.03
Round up: you need an average treatment price of at least £42 to take home £30,000.
Let that sink in
If your average treatment price is below £42, you're not hitting £30k take-home. Not even close. And that's assuming:
- You work 5 days a week, 48 weeks a year
- You do 5 treatments every single working day (no gaps, no no-shows, no quiet Tuesdays)
- Your costs match the estimates above (many practitioners' costs are higher)
In reality, most self-employed beauty professionals have:
- Gaps in the diary (especially mid-week)
- No-shows and late cancellations
- Quiet months (January, post-summer)
- Higher costs than they realise
Which means you probably need an average treatment price closer to £45-50 to reliably hit £30,000 take-home.
What if you want more than £30,000?
Fair enough. £30,000 is modest. Let's run the numbers for different take-home targets.
| Take-home target | Tax + NI | Business costs | Gross revenue needed | Per treatment (1,200/year) |
|---|---|---|---|---|
| £20,000 | £2,711 | £15,720 | £38,431 | £32.03 |
| £25,000 | £3,711 | £15,720 | £44,431 | £37.03 |
| £30,000 | £4,711 | £15,720 | £50,431 | £42.03 |
| £35,000 | £5,711 | £15,720 | £56,431 | £47.03 |
| £40,000 | £6,711 | £15,720 | £62,431 | £52.03 |
| £45,000 | £7,711 | £15,720 | £68,431 | £57.03 |
| £50,000 | £8,711 | £15,720 | £74,431 | £62.03 |
Notes on the tax calculation: These are simplified. As your profit approaches and exceeds the higher rate threshold (£50,270 in 2025/26), the tax rate on additional income jumps from 20% to 40%, and NI changes too. If you're targeting above £50,000, get your accountant to run the exact numbers.
Adjusting for your reality
If you work fewer days
| Days per week | Working days/year | Treatments/year (at 5/day) | Min. per treatment (£30k target) |
|---|---|---|---|
| 5 | 240 | 1,200 | £42 |
| 4 | 192 | 960 | £53 |
| 3 | 144 | 720 | £70 |
Working 3 days a week and taking home £30k means your average treatment price needs to be £70. That's not impossible - but it requires premium pricing, premium services, or longer, higher-value treatments.
If you do fewer treatments per day
| Treatments/day | Treatments/year (240 days) | Min. per treatment (£30k target) |
|---|---|---|
| 6 | 1,440 | £35 |
| 5 | 1,200 | £42 |
| 4 | 960 | £53 |
| 3 | 720 | £70 |
If you only manage 3-4 treatments a day (because of longer service times, gaps, or admin), your per-treatment price needs to be significantly higher.
If your costs are higher
The £15,720 business cost figure is moderate. If you're in London or the South East, your chair rent alone could be £15,000-18,000/year. If you use premium products, your product costs are higher. If you've recently invested in equipment or training, your costs are higher in the short term.
Adjust the numbers for your actual costs. Every £1,000 of extra annual cost adds about £0.83 to your required per-treatment price (at 1,200 treatments/year).
If your costs are lower
Home-based workers with no chair rent have significantly lower costs. If you remove the £10,400 chair rent from the calculation:
- Business costs: ~£5,320
- Gross revenue needed for £30k take-home: ~£40,031
- Per treatment (1,200/year): ~£33.36
Home-based workers need less revenue to hit the same take-home - but that doesn't mean they should charge less. Lower costs mean higher margins, which mean more money in your pocket at the same prices. Don't give away your cost advantage in lower prices. Keep it as profit.
Mobile workers: don't forget travel
If you're mobile, add travel costs:
| Cost | Annual estimate |
|---|---|
| Fuel / mileage (HMRC allows 45p/mile for first 10,000 miles) | £2,000-4,000 |
| Vehicle maintenance and wear | £500-1,000 |
| Parking | £200-500 |
| Travel time (unpaid - this is the big one) | N/A in £, but reduces your available treatment hours |
If you drive 30 minutes each way to a client, that's 1 hour of unpaid time per appointment. If you do 5 clients a day, that's 5 hours of travel - making your working day 10+ hours. Either:
- Charge a travel fee (£5-15 per visit)
- Build travel cost into your treatment prices
- Cluster bookings geographically to reduce travel time
Tip for new starters: If your average treatment price comes out below £35, something is wrong. Go back and check you've included everything, especially tax, NI, and your own time for admin and cleaning.
The pension problem
None of the calculations above include pension contributions. As a self-employed person, you have no employer pension. If you want to retire with any financial security, you need to save for it yourself.
A rule of thumb: save 10-15% of your gross income for retirement. On £50,431 gross, that's £5,043-7,565/year. Add that to your costs and your per-treatment price needs to go up again.
| With pension | Gross revenue needed | Per treatment (1,200/year) |
|---|---|---|
| No pension | £50,431 | £42 |
| 10% pension (£5,043) | £55,474 | £46 |
| 15% pension (£7,565) | £57,996 | £48 |
This is why so many self-employed beauty workers have no pension savings. The numbers feel impossible. But the solution isn't to ignore pensions - it's to charge properly.
The formula
Here's the formula to calculate your own per-treatment price:
Per treatment = (Take-home target + Tax + NI + Business costs + Pension) / Realistic annual treatments
Fill in your own numbers. Be honest about realistic annual treatments - not "if I'm fully booked every day" but "what I actually did last year, including gaps, no-shows, and quiet weeks."
What this means for your price list
Your price list probably has a range of services at different prices. You don't need every service to hit the minimum per-treatment price - you need the average across all services to hit it.
Example mix:
- 30% of appointments are gel nails at £35 = £10.50 weighted
- 20% are acrylic full sets at £45 = £9.00 weighted
- 15% are lash extensions at £65 = £9.75 weighted
- 15% are brow shape and tint at £18 = £2.70 weighted
- 10% are waxing at £25 = £2.50 weighted
- 10% are facials at £55 = £5.50 weighted
- Weighted average: £39.95
If your target is £42, this mix falls short. You'd need to either raise prices across the board, reduce low-value services, or add higher-value services to push the average up.
What to do next
- Decide your take-home target. Be realistic but don't sell yourself short.
- Calculate your actual annual business costs (use your last tax return or bank statements).
- Work out your tax and NI (use HMRC's self-employed tax calculator or ask your accountant).
- Count your realistic annual treatments (actual, not theoretical).
- Divide total required revenue by treatments. That's your minimum average price.
- Compare it to your current average price. If there's a gap, you know what to do.
