Revenue vs profit
Revenue is the total money your business takes in from client payments. If you do 20 appointments at £45 each, your weekly revenue is £900.
Profit is what's left after you subtract your costs. Your £900 revenue minus £250 in overheads (products, insurance, rent, software) = £650 profit.
Profit margin is the percentage: £650 ÷ £900 = 72% profit margin. For every £1 of revenue, you keep 72p. Understanding this number helps you make better pricing, service, and investment decisions.
Gross profit margin
Gross profit margin = (Revenue − Product/direct costs) ÷ Revenue × 100
For nail techs, product costs include: gel, acrylic products, tips/forms, disposables, and any other materials used directly in the service. If your gel manicure service costs £40 and you use £5 of product, your gross margin is (£40 − £5) ÷ £40 = 87.5%.
Net profit margin
Net profit margin = (Revenue − All costs) ÷ Revenue × 100
All costs includes: product costs, rent/chair rent, insurance (professional indemnity + public liability), training, equipment depreciation, booking software, marketing, continuing education, and any other business expenses. What's left is your net profit — your income before tax.
Worked example
| Item | Monthly figure |
|---|---|
| Revenue (20 clients/week × 4 weeks × £45) | £3,600 |
| Product costs (estimated £5/client) | −£400 |
| Chair rent / room hire | −£400 |
| Insurance | −£30 |
| Booking software | −£20 |
| Training / CPD | −£50 (averaged monthly) |
| Other business costs | −£50 |
| Net profit (before tax) | £2,650 |
| Net margin | 74% |

How to improve your margin
Margin improves when either revenue goes up or costs go down. The most practical levers:
| Lever | How it works |
|---|---|
| Raise prices | Affects every appointment immediately; high impact on margin |
| Improve product efficiency | Track how much product you actually use per service; waste adds up |
| Add high-margin add-ons | Chrome, nail art, cuticle treatments: low material cost, meaningful additional revenue |
| Reduce overheads | Negotiate chair rent; switch to a lower-cost booking platform; bulk-buy supplies |
| Fill your calendar | Fixed costs (rent, insurance) stay the same whether you do 15 or 25 clients per week — more clients per week = better fixed-cost coverage |

What's a typical profit margin for a nail tech?
This varies widely by business model, pricing, and overheads. A home-based nail tech with low overheads and good product efficiency might achieve 60–75% net margins. A nail tech renting a chair in a salon, paying for insurance, training, and substantial product costs might sit at 40–55%. These are illustrative ranges, not guarantees — your actual margin depends entirely on your specific costs and revenue.
Should I calculate margin per service or overall?
Both are useful. Per-service margin shows you which services are most profitable (and which might be underpriced relative to their costs). Overall margin shows you whether your business is healthy at the total level. Start with overall, then drill into per-service margins when you want to optimise your pricing or service menu.
Is margin the same as take-home pay?
Not quite. Net profit margin is the percentage of revenue left after expenses — but for a sole trader, "profit" is your pre-tax income. From that, you'll pay income tax and National Insurance (in the UK), and you might reinvest some into the business. Your actual take-home is net profit minus tax. How to calculate your monthly income: see the linked article.
