How Do I Price My Product or Service?
A practical guide to pricing decisions: cost, margin, customer value, competitive context, willingness to pay, pricing model, and discount discipline.
The short answer
There is no universal formula for pricing — the right price depends on your costs, the value the customer places on the outcome, what alternatives they have, and how you want the business to run. The sensible approach is to work through each factor deliberately, set a price with a clear rationale, and then test and adjust it with real customers rather than guessing once and leaving it unchanged.
- Start from cost and required margin, but do not stop there
- Price reflects the value of the outcome to the customer, not just your effort
- Understand what else the customer could do instead, and at what price
- Decide deliberately between recurring and one-off pricing models
- Protect your price with discount discipline, and test changes properly
Why there is no single correct way to price
Pricing advice often promises a formula — cost plus a fixed percentage, or match the market rate — as though one method applies to every business. It does not. A price that works for a low-cost, high-volume product will be wrong for a specialist service sold to a small number of clients, and a price copied from a competitor may ignore real differences in your costs, your positioning, or the value you actually deliver. Pricing is a judgement built from several factors, not a lookup.
The more useful approach is to work through the factors below in order, arrive at a price with a clear rationale behind it, and treat that price as a considered starting point rather than a permanent decision. Prices can and should be revisited as you learn more about what customers are actually willing to pay and how your costs behave at different volumes.
What does it actually cost me to deliver this?
Before anything else, know your true cost of delivery — materials, time, subcontracted work, and a fair allocation of overheads such as software, insurance, or premises. It is common to undercount cost by leaving out your own time or small recurring expenses, which makes a price look profitable on paper when it is not once everything is accounted for. If a service genuinely costs £40 in time and materials to deliver, pricing it at £45 leaves almost nothing to cover the overheads, tax, and risk involved in running the business.
Cost sets a floor, not a target. Pricing exactly at cost, or just above it, leaves no room for the business to absorb the unexpected — a slow month, a bad debt, a price rise from a supplier — and no margin to reinvest in growth. Establish your cost clearly first, then treat it as the minimum below which a sale actively loses the business money, rather than as the basis for the final price.
What gross margin do I actually need?
Gross margin is the gap between what you charge and what it costs to deliver, and it is what funds everything else the business needs: your own income, marketing, admin, tax, and a buffer for the unexpected. A price can look reasonable in isolation and still leave a margin too thin to sustain the business once all of its running costs are considered, not just the direct cost of a single sale.
Work out, realistically, what margin the business needs across its sales as a whole to cover its running costs and leave something over, then check whether your intended price delivers that margin at a volume of sales you can realistically expect. If it does not, the choice is to raise the price, reduce the cost of delivery, or accept that the business model needs rethinking — not to proceed on numbers that do not add up and hope trading improves them.
How do I price based on the value to the customer, not just my effort?
Customers do not pay for your time or ingredients; they pay for the outcome your product or service produces for them. A repair that takes twenty minutes can be worth a great deal to a customer if it prevents a far larger loss, while a service that takes many hours may be worth little if the outcome is marginal. Where possible, think about what the customer gains — money saved, time saved, risk avoided, revenue generated, a problem removed — and price with that outcome in mind, rather than defaulting to effort-based pricing.
This is particularly relevant for services and B2B offers, where the customer's own commercial outcome can often be estimated, even roughly. A proposition that saves a business a meaningful, quantifiable cost each month supports a very different price to one whose benefit is vague or hard to attribute. Being able to explain the value in the customer's own terms also makes the price easier to justify in a sales conversation.
What is the competitive context, and how much should it drive my price?
Understanding what else is available to your customer — direct competitors, substitutes, or simply doing nothing — gives you a realistic sense of the range within which your price needs to sit. If a very similar offer is readily available at a noticeably lower price, a customer needs a clear reason to pay more, whether that is quality, service, speed, or trust. If there is little genuine alternative, there is more room to price according to value rather than matching a market rate.
Competitive context is information, not instruction. Matching a competitor's price without understanding your own costs or differentiation can leave you with an unsustainable margin, and underpricing relative to the market can signal lower quality even when that is not the case. Use what you learn about alternatives to sense-check your price, not to set it automatically.
How do I find out what customers are actually willing to pay?
Willingness to pay is rarely obvious from the outside, and it is one of the few parts of pricing that benefits from direct testing rather than estimation alone. Early, honest conversations with prospective customers — asking what they currently pay for alternatives, or how they would value solving the problem — give a useful starting signal, though people often answer hypothetically worded questions about price less reliably than they behave when actually asked to pay.
A more reliable test is offering the product or service at a real price to real prospects and observing what happens: do they buy, hesitate, or push back, and at what point does resistance appear. Small, early sales at a considered price tell you more than a survey ever will. Where you can, test more than one price point across a small number of genuine sales conversations before settling on a figure for wider use.
Which pricing model actually fits what I am selling?
The pricing model — how you charge, not just how much — shapes customer behaviour and business stability as much as the figure itself. Options include a flat one-off fee, hourly or time-based charging, tiered packages, usage-based pricing, or a subscription. Each suits different circumstances: a subscription fits something delivering ongoing value with ongoing cost to you, while a one-off fee suits a self-contained piece of work with a clear endpoint.
Choose a model that matches how the customer experiences value and how your own costs actually behave, rather than defaulting to whatever is most common in your sector. A model mismatched to the underlying delivery — for example, a subscription for something with no ongoing cost or engagement to justify it — tends to create friction or churn that a simple price change cannot fix.
Should I price for recurring revenue or one-off transactions?
Recurring revenue — subscriptions, retainers, repeat contracts — gives a business more predictable income and generally supports planning, hiring, and investment decisions with more confidence than one-off sales alone. It usually commands a different pricing logic too: a lower regular amount can be worth more over time than a single larger payment, provided retention is genuinely strong rather than assumed.
One-off, transactional pricing suits businesses where the customer's need is genuinely occasional rather than ongoing, and trying to force a recurring model onto an occasional need tends to produce poor retention and reputational friction. Be honest about which category your offer actually falls into, based on how customers actually use it, rather than choosing a model because recurring revenue sounds more attractive on paper.
How do I avoid discounting away my margin?
Discounting is often used as a quick way to close a hesitant sale, but habitual discounting erodes margin and quietly resets what customers expect to pay, making the full price harder to charge later. Before offering a discount, be clear about why the customer is hesitating — price is not always the real objection — and whether a discount actually solves that, or simply postpones the same resistance at a lower margin.
Where a discount is used, it should be deliberate and bounded: tied to a specific reason such as volume, an early commitment, or a trial period, with a defined end point, rather than offered as a general concession whenever a customer pushes back. Protecting your price in early sales conversations is also protecting the business's ability to sustain itself once the discount period ends.
How often should I test and revisit my price?
A price set at launch, based on the best information available at the time, should not be treated as fixed indefinitely. As you gather more evidence — conversion rates at the current price, customer feedback, changes in your own costs, or a clearer understanding of the value delivered — revisit the price deliberately rather than leaving it unchanged out of habit or discomfort about raising it.
Changing a price, particularly raising it, feels uncomfortable, but an under-priced offer that converts easily is not necessarily a success if it leaves the business unable to sustain itself. Treat pricing as an ongoing commercial decision to be reviewed periodically with real data, in the same way you would review costs or marketing spend, rather than a one-time choice made at the very start and never revisited.
