Most small businesses set their first price in about four minutes. They look at what a competitor charges, shade it slightly downward, and get on with the work. Then they spend the next three years wondering why a busy month doesn't turn into money in the bank.
The takeaway: there are only three real inputs to a price — your cost, your customer's perceived value, and the market's reference points — and a defensible price is built by using all three in a fixed order. Cost sets the floor you must not go below. Value sets the ceiling anyone will pay. The market tells you where inside that band you're positioned. Pick one of those and ignore the other two and you will either lose money on every sale or leave money on the table on every sale.
Step 1: Find the floor (what it actually costs you)
You cannot price anything until you know your unit cost, and most owners under-count it. There are two layers.
Direct costs are what one unit consumes: materials, packaging, the shipping you absorb, the payment-processor fee, subcontracted labour, the hours you personally put in valued at a real rate. For a service business, the hours are the direct cost.
Overheads are what the business consumes regardless: rent, software subscriptions, insurance, your admin time, accounting fees. These don't belong in unit cost directly, but they must be covered by the total contribution all your units generate.
A worked example, service side. Say you make hand-poured candles:
- Wax, wick, fragrance, vessel: £4.10
- Label and box: £0.70
- Your labour, 20 minutes at £18/hour: £6.00
- Payment fee, roughly 2% of a ~£28 sale: £0.56
Direct cost per unit: £11.36. That's the floor. Any price below it loses money on every single sale, and volume makes it worse rather than better.
Then ask the overhead question: if your fixed monthly costs are £1,200, and each candle contributes (price − £11.36), how many must you sell to cover them? At a £28 price the contribution is £16.64, so you need about 73 candles a month before you've earned a penny. That calculation is worth doing properly for any product you're serious about — the full method is in our break-even analysis guide.
Step 2: Don't confuse margin with markup
This is the single most expensive arithmetic mistake in small-business pricing, so it deserves its own section.
- Markup is profit as a percentage of cost: (price − cost) ÷ cost.
- Margin is profit as a percentage of price: (price − cost) ÷ price.
Take a £10 cost item sold at £13. That's a 30% markup — and a 23.1% margin. Not the same number, and the gap widens as the percentages rise. A 50% markup is a 33.3% margin. Doubling your cost gets you a 50% margin, not a 100% one.
Owners who apply "a 40% markup" while believing they've secured a 40% margin are running roughly 28.6% margins and building budgets on a number that doesn't exist. When it comes time to absorb a supplier increase or fund a discount, the cushion they thought they had isn't there.
The formula that matters, because it works backwards from the outcome you want:
price = cost ÷ (1 − target margin)
For that £11.36 candle at a 60% target margin: £11.36 ÷ 0.40 = £28.40. Note that a 60% margin means multiplying cost by 2.5, not by 1.6. If margin arithmetic still feels slippery, our profit margin guide walks through it slowly.
Step 3: Find the ceiling (what it's worth to them)
Cost tells you what you can't do. It tells you nothing about what you should do. Two businesses with identical costs can legitimately charge amounts that differ by a factor of three, because their customers are buying different things.
Value-based pricing means asking what the purchase is worth to the buyer:
- What does it replace, and what does that cost? A bookkeeping service priced against "the eight hours a month the owner currently spends" has a very different ceiling than one priced against "£25 an hour."
- What does it make or save? If your product plausibly earns a business £500 a month, £99 a month is an easy decision for them and a strong price for you.
- What's the cost of the problem going unsolved? Emergency and risk-reduction purchases carry higher ceilings than convenience ones.
- Who exactly is buying? The same product sold to a hobbyist and to a professional supports different prices, because the professional's alternative is more expensive.
The practical way to find the ceiling without guessing is to ask actual buyers. Not "what would you pay?" — people are poor at answering that. Ask what they use now, what it costs them, what annoys them about it, and what happened the last time they went without. The number falls out of those answers.
Value pricing is easiest to apply to services, expertise, custom work, and anything with a measurable outcome. It's hardest for undifferentiated physical goods, where the buyer can see fifty near-identical listings.
Step 4: Position within the market
Now look at competitors — third, not first. You're not copying their number; you're learning three things:
- The reference range. What buyers have been trained to expect. Price far outside it and you need an obvious reason, communicated clearly.
- What they include. A rival "cheaper" price that excludes delivery, setup, or support isn't cheaper. Compare total cost to the customer.
- The gaps. If everyone clusters at the budget end, there is often room at the premium end, and vice versa.
Then decide where you sit deliberately: budget (you must have a genuine cost advantage or you're just subsidising customers), mid-market (crowded, needs a clear reason to choose you), or premium (needs proof — quality, speed, specialisation, warranty, or service).
Beware the reflex of undercutting. Being 10% cheaper than the market is the easiest position to copy and the hardest to profit from. If your only differentiator is price, your customers' loyalty extends exactly as far as the next person willing to go lower.
Step 5: Choose the pricing model, not just the number
The structure often matters more than the figure:
- Flat / unit pricing. Simple, easy to compare, easy to be undercut on.
- Tiered (good-better-best). Three options reframe the customer's question from "yes or no" to "which one" — and the middle tier usually becomes the default. Widely used because it works; make sure each tier is genuinely different, not artificially crippled.
- Subscription / retainer. Trades some headline price for predictable cash flow, which is often the better trade for a small business.
- Bundles. Raise average order value and make direct price comparison harder, legitimately.
- Usage-based. Fair-feeling and scales with the customer, but makes your revenue harder to forecast.
Step 6: Sanity-check before you commit
Run the price through four tests:
- Break-even test. At this price and your realistic volume, do you clear fixed costs with room to spare?
- Discount test. Could you survive a 15% discount or a supplier cost increase? If not, the margin is too thin.
- Own-pay test. Does the total profit at plausible volume actually pay you? A price that keeps you busy and broke is a bad price.
- Round-number test. Adjust to a clean, credible figure. £28.40 becomes £29 — check that the rounding goes up, not down, and that the extra doesn't push you past a psychological threshold that matters in your category.
Then set a review date. Prices are decisions, not settings, and the question of when to move an existing one is covered in should you raise your prices.
FAQ
What's a good profit margin for a small business?
It varies enormously by sector, so any single "good" number is misleading. What's useful instead is your own trend and your own break-even: is your margin holding or eroding, and does it comfortably cover fixed costs at realistic volume? Compare yourself to your last quarter and to your industry's published norms rather than to a generic figure.
Should I price low at first to attract customers?
Introductory pricing can work if it's explicitly time-limited and you've checked you can survive it. The danger is anchoring — customers who joined at the low price treat it as the real one, and raising it later costs you goodwill you didn't budget for. A launch discount with a stated end date is safer than a permanently low price you hope to grow out of.
How do I raise a price without losing customers?
Give notice, explain what's changed, and where possible pair it with something added. Expect to lose a small number of the most price-sensitive customers — that is a normal and often profitable outcome, since those customers usually consume the most support for the least margin.
Do I include my own labour in the cost of a product I make myself?
Yes. Leaving your labour out makes a product look profitable when it is really being subsidised by unpaid work, and it hides the fact that you can't hire anyone to do it at that price. Value your hours at what you'd have to pay a replacement.
Cost-plus or value-based — which should I use?
Use both. Cost-plus establishes the floor you must clear; value-based establishes the ceiling the market will bear. Cost-plus alone systematically underprices anything valuable, and value-based alone can leave you selling above cost on paper while missing an overhead you forgot to count.
