Step 1: Calculate your gross revenue
Gross revenue is the total money your clients pay you in a month. Add up all payments received:
- All appointment payments (including deposits counted in the month they're redeemed)
- Retail product sales (if any)
- Training income (if you teach)
Step 2: Subtract your business expenses
Deduct all business expenses from your gross revenue to get your gross profit:
- Product and supply costs
- Rent / chair rent
- Insurance
- Software subscriptions
- Training (averaged monthly)
- Equipment depreciation (averaged monthly)
- Marketing costs
- Any other business costs

Step 3: Provision for tax
As a self-employed sole trader in the UK, you pay income tax and National Insurance on your profit (revenue minus allowable business expenses). The amount depends on your profit level and your Personal Allowance.
Step 4: Your net monthly income
Net monthly income = Gross revenue − Business expenses − Tax provision
This is your actual take-home pay — the money available for personal spending, saving, and investment.
Full worked example
| Item | Monthly amount |
|---|---|
| Gross revenue (22 clients/week × 4.3 weeks × £42 avg) | £3,970 |
| Product costs (approx. £5/client) | −£473 |
| Chair rent | −£400 |
| Insurance (monthly) | −£28 |
| Software and tools | −£25 |
| Training (averaged) | −£50 |
| Other costs | −£30 |
| Gross profit | £2,964 |
| Tax provision (approx. 25%) | −£741 |
| Net monthly income | £2,223 |
How to improve your monthly income
- Raise your prices — the most impactful single change
- Add more billable hours — one additional client per day × 4 weeks = significant monthly revenue increase
- Increase average appointment value — consistent add-on sales add up
- Reduce product waste — improving product efficiency reduces a significant variable cost
- Reduce overheads — audit what you pay for and whether it generates value

Do I need to pay tax as a self-employed nail tech?
In the UK, if you earn above the Personal Allowance threshold as a sole trader, you pay income tax and Class 4 National Insurance on your profits. You register with HMRC as self-employed and file a Self Assessment tax return annually. How much you pay depends on your profit level. This article is not tax advice — check HMRC.gov.uk or consult an accountant for your specific situation.
What's a realistic monthly income for a nail tech?
This varies enormously by location, experience, client volume, pricing, and business model. A full-time nail tech with a solid client base in a UK city might take home £1,800–£3,000+ per month after expenses. A part-time tech or someone building their client base will take home less. The calculation in this article lets you work out your specific number rather than relying on generalisations.
How do I handle irregular monthly income?
Income varies month to month for most nail techs — December is often high; January is often low. A useful approach: calculate your average monthly income over 3–6 months rather than relying on any single month. Keep a financial buffer (savings that cover 1–2 months of expenses) so a quiet month doesn't cause cash flow stress.
