How to price trade jobs without guessing your margin

A full diary can hide weak pricing. You finish one job, collect materials for the next and spend the evening sending quotes. Money comes in, but it is difficult to tell which work is actually contributing enough to the business. The problem is often less about knowing what competitors charge and more about understanding what your own jobs consume.

Pricing trade work requires two different views. First, estimate the resources needed to deliver the agreed result. Then decide the selling price, considering the return the business needs and the value of the work to the customer. Mixing those views together makes it harder to explain a price or understand why a job underperformed.

This guide offers a practical method for small UK trade businesses. Every figure is an illustrative management example, not a recommended rate, market benchmark or tax calculation. The worked examples use amounts excluding VAT for comparability. Use your own records and appropriate accounting advice to decide how costs and tax should be treated in your business.

1. Begin with a scope you can estimate

A number becomes more useful when it describes a specific job. Before calculating a price, write down the result, the main tasks, the quantities and any assumptions that affect delivery. A vague brief produces a vague estimate, however sophisticated the spreadsheet looks.

Break the work into activities that can be checked. For a small installation, these might include preparation, removal, fitting, testing appropriate to the work and clearing away. For decorating, they might include protection, surface preparation, painting and final checks.

Then identify the uncertain parts. Is access confirmed? Have you inspected the existing condition? Is the customer supplying something that has not arrived? Uncertainty does not always mean refusing to quote, but it should influence what you investigate and how you describe the offer.

If you cannot explain the scope to another person, return to the enquiry before adding more precision to the figures. Our guide to writing a trade quote covers the customer-facing version of this work.

2. Estimate the labour the whole job will consume

Start with time, rather than immediately applying an hourly charge. How long will each activity take, and how many people are required? Two people for four hours represent eight labour hours, even if the customer sees a half-day visit.

Include work that belongs directly to the job but is easy to overlook: preparing equipment, collecting specific materials, setting up protection, clearing the site and making an agreed return visit. Decide consistently which activities you allocate to individual jobs and which you treat as general overhead.

Avoid counting the same time twice. If your labour allowance already includes a materials collection, do not also add that collection as a separate full block elsewhere. Consistency matters more than an impressive number of categories.

For unfamiliar work, use a range internally before settling on the customer proposal. Ask what would need to be true for the shorter duration and what could cause the longer one. That exposes assumptions you can check before committing to a price.

3. Separate hourly cost from customer charge rate

An hourly cost helps you understand what providing labour costs the business. A customer charge rate helps you decide what to sell that labour for. They serve different purposes and should be recorded separately.

How you calculate labour cost depends on the working arrangement and your management accounting approach. Employee wages alone may not capture every employment cost. Subcontractor costs may follow an agreed rate or a price for a package of work. An owner’s time also needs a consistent treatment if you want useful job comparisons.

Do not treat all money above a worker’s hourly pay as profit. The business still has costs beyond the immediate job. Equally, avoid loading the same overhead into several different parts of the estimate without noticing.

Write down what your rates include and review that basis periodically. In Jobsworth, team member cost and charge rates are configured separately, and existing records retain their saved rates when the settings change.

4. Price materials as quantities, not vague allowances

List the materials needed for the scope and use quantities you can trace. Include relevant consumables and any job-specific delivery or disposal costs in your estimate. A familiar headline item can distract from the smaller purchases that accumulate around it.

Check the purchasing basis. A supplier may sell a product by the pack when your estimate is expressed by the unit. Some items can be used on another job; others are effectively committed to this one. Make that distinction consciously rather than assigning a convenient round figure.

Treat waste and uncertainty sensibly for the particular work. There is no single percentage that is right for every trade, material or site condition. Use experience from similar jobs and adjust when the scope or access differs.

Keep cost and selling price visible internally. You may choose to sell materials with a margin, include them in a fixed job price or use another agreed approach. The customer offer should accurately describe that approach without requiring you to reveal the whole internal costing model.

5. Understand direct costs and overheads

Direct costs are costs you associate with delivering a particular piece of work. For a simple management example, these might include labour, materials and hired equipment. Overheads support the business more generally: software, insurance, office costs or other expenses that are not assigned to that individual job in your model.

The distinction depends partly on how you organise your records. A van expense might be allocated across jobs in one business and treated centrally in another. What matters for comparing jobs is using a consistent basis and understanding what the figures leave out.

Job gross profit is not the same as the money the owner can take home. A job can show a positive return after direct costs while contributing too little towards overheads and the wider business.

Use the job view to assess delivery and the business accounts to assess the overall result. Neither view completely replaces the other. If your job reports and accounts appear to disagree, check the cost definitions before assuming one of them is wrong.

6. Calculate markup and margin correctly

Markup and margin use the same profit amount but divide it by different numbers. Confusing them can produce a selling price that is lower than intended.

For a simplified job with £600 of direct costs and a selling price of £900:

Measure	Calculation	Result
Gross profit	£900 selling price − £600 direct costs	£300
Markup on direct costs	£300 ÷ £600	50%
Gross margin	£300 ÷ £900	33.3%

Adding 50% to the £600 cost gives a £900 selling price. It does not create a 50% margin. To obtain a 50% gross margin on that same cost base, the selling price would need to be £1,200.

When working backwards from a target margin, the formula is: selling price equals direct cost divided by one minus the target margin expressed as a decimal. For a 40% margin on £600, that is £600 divided by 0.60, giving £1,000. The example explains the arithmetic; it does not prescribe a suitable target for your trade.

7. Work through a complete small-job example

Imagine a fictional repair job with a clear scope. The business expects eight labour hours at an internal cost of £25 per hour, £180 of materials and £20 of other direct costs. Total estimated direct cost is therefore £400.

The customer price is £650, excluding VAT in this example. Estimated gross profit is £250. That represents a markup of 62.5% on direct costs and a gross margin of approximately 38.5% on sales.

After the job, the records show ten labour hours at the saved £25 cost rate, £195 of materials and the same £20 of other direct costs. Actual recorded direct cost is £465. If the selling price remains £650, gross profit is £185 and gross margin is approximately 28.5%.

The business has not necessarily made a bad decision by taking the job. It has discovered a £65 difference worth understanding. Two additional labour hours account for £50 and materials account for £15. That is a much more useful conversation than saying the job “felt a bit tight”.

8. Investigate differences before changing every rate

A cost overrun can have several causes. The estimate may have been too optimistic, the scope may have changed, access may have been delayed or the team may have needed to correct something. Each explanation calls for a different response.

If preparation consistently takes longer than allowed, improve the estimating template. If customers frequently add work, improve the change conversation and record the agreement. If the team repeatedly arrives without essential materials, review preparation and scheduling.

Raising every price may increase income, but it will not tell you why a particular job went wrong. First separate a pricing issue from a delivery issue. You can then decide whether the rate, the process or both need attention.

Use notes as well as numbers. A short explanation recorded during the work is often more useful than trying to reconstruct the cause several weeks later. Compare similar jobs where possible, and avoid drawing a firm conclusion from one unusually difficult visit.

9. Record billable and non-billable time honestly

Time records are useful when they describe what happened. If you only record hours that will appear on an invoice, you can lose sight of the effort required to deliver fixed-price work or resolve problems.

Keep billable and non-billable classifications separate from whether the time mattered. A return visit may be non-billable but still reveal a cost worth understanding. Internal preparation may be essential even when it is not shown as a separate customer charge.

Give the team a simple way to record time with enough context to make sense later. Avoid a complicated list of categories nobody can reliably choose between. A clear link to the job and a short note may provide most of the value.

Review the entries before importing charges into an invoice draft. A time record is evidence for managing the work; whether and how it is billed follows the customer agreement. Do not silently convert every recorded hour into an extra charge on a fixed-price job.

10. Keep changes visible before they become surprises

When a customer asks for something outside the agreed scope, pause long enough to explain its effect. Record the requested change, any additional work, the price implication and the decision. Keep it connected to the original job.

This is particularly useful when a small request sounds easy but changes the sequence. Adding one item might mean another delivery, a second person or a return visit. The cost is not always the item itself.

Avoid using an internal cost variance as an automatic reason to increase the customer’s bill. Your estimate and the agreed customer price are different records. If the business underestimated a defined scope, that requires a different conversation from genuinely additional work.

Business Companion’s supplying-services guidance, for England and Wales, discusses changing a contract by agreement. Build your working process around clear communication and recorded agreement, with terms appropriate to the customers and locations you serve.

11. Review pricing with a small, consistent scorecard

Choose a manageable set of completed jobs and compare them using the same definitions. Record quoted value, estimated direct cost, recorded direct cost, labour hours and a short explanation of significant differences.

Then group the findings in a way that supports a decision. You might compare repair visits with installations, work close to your base with distant jobs, or familiar services with less predictable ones. The purpose is to improve your next estimate, not produce a complicated report.

Look at accepted and declined quotes alongside delivered jobs. A high acceptance rate is not automatically evidence of good pricing if the resulting work contributes too little. A lower acceptance rate may still support a healthy business if the jobs won fit your capacity and earn an appropriate return.

Keep the review grounded in your own records. External pricing anecdotes can prompt questions, but they do not tell you another business’s cost base, scope or customer mix.

12. Put the method into your next five quotes

You do not need to rebuild your entire business overnight. Choose a familiar type of work and use a consistent estimating structure for the next five quotes. Record the main labour activities, material quantities, assumptions and selling price.

For the jobs you win, capture actual time and costs. Set a short review after completion and identify one improvement. After several comparable jobs, your estimate should be based more on evidence and less on a remembered good day.

Keep the information connected from quote to job to invoice. Jobsworth’s time, materials and estimating workflow supports separate rates, estimates, time records and selected charges imported into invoice drafts. That connection makes the comparison easier to revisit.

The useful outcome is a price you understand and a job you can learn from. When you know what the work required, what you charged and why the result differed, the next commercial decision becomes clearer.
