How to Calculate Pricing for a UK Small Business
A simple, repeatable pricing process for UK small businesses — combining costs, margin and break-even into one clear formula.
The three things every price has to cover
- Direct cost — what it costs you to deliver one unit (product cost, your time, packaging)
- Margin — the profit you keep on every sale to cover overheads and pay yourself
- Buffer — a small cushion for discounts, scope creep, quiet weeks and unexpected costs
If your price misses any of these, you'll be busy but unprofitable.
The simple pricing formula
Price = Cost ÷ (1 − target margin)
Then add: 5–10% buffer
To hit a 40% margin on a £30 cost: £30 ÷ (1 − 0.40) = £50. Add a 10% buffer → £55. That's your quote.
Worked example: product business
- Cost to make: £12
- Target margin: 50%
- Price = £12 ÷ 0.5 = £24
- +10% buffer = £26
£26 is the retail price. The buffer absorbs the inevitable promotion or shipping refund.
Worked example: service business
- Daily cost (your time, software, admin): £300
- Target margin: 40%
- Price = £300 ÷ 0.6 = £500/day
- +10% buffer = £550/day

Combine pricing with break-even
A price isn't safe until you know how many you need to sell. Use the Break-even Calculator to check whether the volume needed at your price is realistic.
If your break-even is 400 units a month but you sell 100, your price is too low, your costs are too high — or both.
Check the margin you're actually getting
After picking a price, plug it back into the Profit Margin Calculator to confirm the real margin. This catches the classic mistake of confusing margin and markup — see the full guide on Markup vs Margin Explained.
Common pricing mistakes
- Pricing by gut feel — every quote should start from a number, not a vibe
- Forgetting the buffer — every business takes some hits; price for them
- Confusing margin and markup — a 30% markup is only a 23% margin
- Not factoring your own time — your hours are a cost, even if you don't pay yourself a salary
- Matching competitors blindly — their costs aren't your costs

Frequently asked questions
What's a simple pricing formula for a UK small business?
Start with cost, add your target margin, then add a buffer for variability. The simple form is: Price = Cost ÷ (1 − target margin), then add 5–10% for scope creep, discounts and quiet periods.Should I price based on cost or based on value?
Both. Cost sets the floor — never sell below it. Value sets the ceiling — what the market will pay. The price you actually quote should sit comfortably between the two.How do I know if my prices are too low?
Three warning signs: you're always busy but never profitable, clients accept your quotes immediately without negotiation, and you can't take a holiday without losing money. All point to under-pricing.Do I need to factor VAT into my pricing?
Only if you're VAT registered. If you are, decide whether your headline price is VAT-inclusive (consumer-facing) or VAT-exclusive (B2B). Use the VAT Calculator to add or remove VAT on any figure.
