Pricing a product or service feels like it should be simple: figure out what it costs, add a bit on top, done. In practice, businesses price themselves into difficulty with surprising regularity — sometimes charging too little to remain viable, sometimes charging too much to remain competitive, and frequently confusing margin with markup in ways that produce entirely the wrong answer.
Good pricing starts with understanding your numbers. Once those are clear, there are several approaches that suit different business models and markets. Let's go through them systematically.
Cost-Plus Pricing: The Foundation
Cost-plus pricing is the most straightforward method: calculate your total cost to produce or deliver something, then add a margin on top. Simple in principle, but the execution is where businesses go wrong — usually by forgetting to include all costs.
Your cost includes direct costs (materials, labour directly attributed to this product or job), indirect costs (overheads — rent, utilities, admin, insurance, marketing, your own time), and the cost of any returns, warranty claims, or support that the product generates. Many small businesses calculate cost based on direct costs alone, add a margin, and wonder why they're working hard but not making money. It's because the overheads aren't being covered.
Use our profit margin calculator to check that your prices are generating the margin you think they are. Enter your selling price and cost, and the calculator shows gross margin percentage — the real health metric for pricing decisions.
Markup vs Margin: The Confusion That Costs Businesses
These two terms are frequently used interchangeably. They're not the same thing, and confusing them can cause you to significantly underprice.
Markup is calculated on cost: if something costs £50 and you apply a 50% markup, you sell it for £75. Your profit is £25.
Margin is calculated on the selling price: that same £25 profit on a £75 sale price is a 33% margin.
The problem arises when a business aims for a 50% margin but applies a 50% markup. The actual margin at 50% markup is only 33%. On a high volume of transactions this gap becomes material very quickly. If you're targeting a specific margin, calculate your required selling price from margin — not from markup.
Break-Even Analysis: The Number That Anchors Everything
Before worrying about profitability, you need to know your break-even point: the volume of sales at which revenue equals total costs, producing neither profit nor loss. Below this point you lose money. Above it you make money.
Break-even is calculated as: Fixed Costs ÷ Contribution Margin per Unit (where contribution margin = selling price minus variable costs per unit).
Our break-even calculator automates this calculation. Enter your fixed monthly costs, your variable cost per unit, and your selling price, and you'll see exactly how many sales you need to make before you start generating profit. Use it to sanity-check pricing decisions: if your break-even requires you to sell 2,000 units per month but your realistic market is 400 units, the pricing model doesn't work regardless of how attractive the margin looks on paper.
Value-Based Pricing
Cost-plus tells you your floor — the minimum viable price. Value-based pricing looks at the ceiling: what is the product or service actually worth to the customer? A business consultant who saves a company £200,000 per year through operational improvements is not priced on their cost (time and expertise) — they're priced on the value they deliver.
Value-based pricing requires understanding your customer's alternatives. If they could achieve the same outcome by hiring a member of staff at £40,000 per year, hiring you at £30,000 still makes sense for them — and you could justifiably charge more than your direct time cost suggests.
For product businesses, the question is: what is the buyer's willingness to pay? This often exceeds cost-plus by a significant margin in markets where the product is differentiated, where alternatives are limited, or where emotional or status value is embedded in the purchase.
Competitive Pricing
Pricing at, above, or below competitors is a strategic choice, not just a market constraint. Pricing above the market signals quality and exclusivity but requires that positioning to be credible — customers must believe the premium is justified. Pricing below the market is a race to the bottom unless your cost base is genuinely lower or you're pursuing market share as a strategic priority.
Matching competitor pricing is the default for commoditised markets where differentiation is minimal. In these markets, cost efficiency is the critical variable — you need a cost base that allows you to make money at the market price, or you need to exit the commodity segment.
Psychological Pricing
Human beings don't evaluate prices rationally. £9.99 consistently outperforms £10 in purchase conversion despite the difference being trivial. Premium prices can actually increase perceived value — a wine priced at £40 tastes better to most people than the same wine priced at £15. Anchoring effects mean that showing a higher price first (struck through with a discount) increases purchase likelihood even when buyers know the tactic.
None of these effects override fundamentals — if your price is genuinely too high for the value delivered, no amount of psychological framing rescues it. But they're worth understanding and deploying where relevant.
The Federation of Small Businesses has useful guidance on pricing strategies for small businesses including sector-specific considerations worth reviewing before setting or revising your pricing.
Review Pricing Regularly
Costs change. Markets shift. Competitors adjust. A price that was right 18 months ago may no longer reflect your cost base or your market position. Build pricing reviews into your annual planning cycle — and when costs increase significantly, don't absorb them silently. Customers generally accept price increases that are explained clearly, far better than businesses assume they will.
