Pricing for Profit
Why cost-plus pricing quietly bankrupts good businesses, and a straightforward method for pricing that protects your margin instead of just covering your costs.

The short answer
Price is a profit decision, not a cost sum
Most small businesses price by adding a bit onto what something cost them. That feels safe, but it only works if every cost has been counted — and most owners forget their own time, their overheads, and the jobs that go wrong. If your pricing is essentially a multiplication of your direct costs, you're missing the bigger picture that sustains your business in the long run.
Pricing for profit means starting at the other end. Decide what profit the business needs to be worth running, work out the volume you can realistically sell, and build the price from there. The market then tells you whether that price is credible — but you never start from cost alone. This approach ensures that every job contributes to your financial goals, not just covers its own cost.
If you only price to cover costs, you are running a charity for your customers. Profit is not what is left over at the end; profit is the first line you write into the quote. This mindset shift can transform your pricing strategy from reactive to proactive, ensuring that your business thrives rather than merely survives.
The four inputs you actually need
Before you can price anything sensibly, you need four figures in front of you at the same time. These figures provide the foundation for a price that reflects the true value of your services and the sustainability of your business model.
Direct costs include everything that is specifically tied to the job — materials, subcontractors, and transaction fees. Ignoring these leads to underpricing and eating into personal profits. Properly accounting for direct costs ensures that each job covers its immediate expenses, freeing your margin to support the business's broader needs.
Your time, properly costed — not the minimum wage, but a realistic day or hourly rate that reflects what you would need to pay someone to replace you. By recognizing the value of your time, you prevent burnout and maintain a professional standard that supports growth.
- Direct cost — materials, subcontractors, transaction fees: costs that only exist because you did this specific job.
- Your time, properly costed — not the minimum wage, but a realistic day or hourly rate that reflects what you would need to pay someone to replace you.
- A fair share of overheads — rent, software, insurance, admin time — spread across the work you expect to do in a year.
- The profit you need — not what is left over by accident, but a deliberate percentage set aside before anything else is spent.
Why 'what the market charges' is not a strategy on its own
Checking competitor prices tells you what is possible, not what you need. A competitor with lower overheads, cheaper labour, or a loss-leading strategy can charge less than you and still be fine — while the same price would ruin you. Blindly mirroring market prices can lead to unsustainable pricing structures and long-term financial strain.
Use market prices as a sense check after you have built your own number from costs and required profit, not as the starting point. If your required price is well above the market, that is a signal to change the offer, the costs, or the customer — not to quietly absorb the gap yourself. This approach is about maintaining integrity, both in your financial health and your market position.
Often, the market rate is set by businesses that are themselves failing to price for profit and will be bankrupt within two years. You do not want to anchor your pricing to a sinking ship. Instead, focus on ensuring your pricing aligns with your strategic goals and long-term sustainability.
Worked example: A joiner pricing a fitted wardrobe job
- Materials and hardware
- £420
- Labour, 3 days at a realistic day rate of £220
- £660
- Overhead allowance (van, insurance, tools, admin)
- £140
- Full cost
- £1,220
- Required profit margin, 20%
- £305
- Price to quote
- £1,525
Illustrative example. Pricing from cost-plus-a-bit at £1,220 plus a vague 10% would have produced £1,342 — undercharging by £183 once the day rate and overhead allowance are properly included, not just materials. This method demonstrates how critical it is to factor in all aspects of your cost structure to avoid unintentional underpricing and ensure sustainable profitability.
What to do, in order
- 1
Cost your own time honestly
Work out a day or hourly rate that reflects what replacing you would cost, including time you do not bill. This prevents undervaluing your business and ensures that your pricing reflects the true value of your expertise.
- 2
Add a real overhead allowance
Spread your annual overheads across your realistic billable days, and add that per-job. Failing to account for overheads can transform a seemingly profitable job into a liability, impacting your bottom line.
- 3
Set the profit percentage before quoting
Decide the margin the business needs — commonly 15-25% for services — and add it deliberately. This prevents treating profit as an afterthought and reinforces your business's ability to invest in growth and innovation.
- 4
Sense-check against the market
Compare the resulting price to what competitors charge, and understand any gap rather than closing it silently. This ensures competitive advantage without compromising your financial viability.
- 5
Quote the number and hold it
Discount only if you also reduce scope, cost, or accept a lower margin knowingly. This approach prevents profit erosion and reinforces the value of your service in clients’ perception.
- 6
Review prices at least twice a year
Costs and overheads move even when you do not notice, and prices should move with them. Regular reviews prevent profit margins from quietly slipping over time, ensuring long-term sustainability.
Common mistakes
- Pricing from materials cost alone and forgetting labour and overhead entirely.
- Copying a competitor's price without knowing their cost base or margin.
- Treating profit as whatever is left over, rather than a figure decided in advance.
- Never revisiting prices once set, even as costs rise year on year.
- Discounting to win work without reducing scope, eroding margin on every job that follows.
- Neglecting to factor in unexpected costs such as project overruns or reworks, which can turn a profitable project into a loss.
- Assuming high volume will compensate low margins without considering the increased wear on resources and potential quality dips.
- Underestimating the cumulative impact of small, systematic pricing errors that can erode annual profits significantly.

Frequently asked questions
- Should I price the same for every customer?
- Not necessarily. Different customers cost you different amounts to serve — in time, risk, and admin. It is reasonable to price differently as long as each price still covers full cost plus your required margin. Tailored pricing strategies can also be used as a strategic tool to reward loyalty or incentivize long-term relationships.
- What if my required price is above what customers will pay?
- That is useful information, not a reason to cut your margin quietly. It usually means the offer, the target customer, or the cost base needs to change, rather than the profit you are prepared to accept. Adjusting your business model to align with market realities can enhance competitiveness and profitability.
- How often should I review my pricing?
- At least twice a year, and immediately after any significant change in your costs, such as a supplier price rise or a jump in overheads. Regular reviews ensure your pricing strategy remains compatible with current market conditions and your own operational needs.
- How do I incorporate fluctuating costs into pricing?
- Develop a pricing strategy that includes a buffer for cost fluctuations. This can mean setting a flexible pricing system based on cost indexes or renegotiating contracts that allow for price adjustments. The goal is to ensure unexpected changes don’t immediately erode your margins.
- What is the best way to communicate price increases to clients?
- Clearly and transparently explain the reasons for the increase, detailing any changes in cost and the value you continue to provide. It's also effective to give clients advance notice and offer to answer any questions they might have. This approach maintains trust and helps manage client expectations.
