How to Calculate Your Charge-Out Rate as a Contractor or Tradesperson

How do you calculate a charge-out rate, step by step?

The method is the same for a sole trader with a van and a firm of twenty-five. It turns the cost of running the business into a figure every chargeable hour must carry, then adds labour and profit.

The six steps below take about an hour the first time, if you have last year's accounts or bank statements to hand.

• 1. List a full year of overheads: every cost that would still exist if you had no jobs this month.
• 2. Count productive hours: people on the tools x paid hours per week x the productive share of those hours x working weeks per year.
• 3. Divide overheads by productive hours. That is your overhead recovery rate per hour.
• 4. Work out direct labour cost per productive hour: wages plus employer on-costs, divided by productive hours.
• 5. Add the two. That is your break-even cost per hour: charge less and every hour loses money.
• 6. Divide the break-even cost by (1 minus your target net margin). That is your true charge-out rate. Compare it with the market, then decide.

What counts as an overhead for a trades business?

An overhead is a cost of running the business that no single job pays for directly. The test is simple: would this cost still be there in a month with no jobs? If yes, it is an overhead. If it exists only because of a particular job, it is a direct cost and belongs in that job's price.

The overheads small contractors most often forget are their own time spent quoting, ordering and chasing; fuel and travel not charged to jobs; small tools and consumables; apprentice college days; and a replacement fund for tools and plant. Leave them out and your rate assumes you work evenings for free and never replace a mitre saw.

How many productive hours does a tradesperson really have?

Fewer than most owners think. A tradesperson paid for 40 hours a week does not spend 40 hours on work you can charge for. Travel between jobs, loading the van, collecting materials, waiting for deliveries, weather, training, yard tidying and putting right callbacks all take paid time that no client pays for directly.

The productive share is the part of paid time that can be charged to jobs. If you do not know yours, look at four weeks of timesheets and divide the hours booked to jobs by the hours paid. Then remove holidays, public holidays, sickness and quiet weeks to get working weeks per year.

This number matters as much as your overheads. Raising the productive share, for example by having materials delivered rather than collected, lowers the overhead recovery rate without cutting a single cost. Research on the industry points the same way: the McKinsey Global Institute's 2017 report Reinventing Construction found construction labour productivity grew about 1% a year over two decades, against 2.8% for the world economy, and much of the gap is about planning and organisation.

What does a worked example look like?

Here is a composite five-person renovation firm: the owner on the tools half the week, two employed carpenter-builders, an apprentice counted as a full-time equivalent, and a part-time office manager whose wage is an overhead. Figures are in GBP but the arithmetic works in any currency.

Read the table from top to bottom. The first three lines are the overhead recovery calculation; the next two add labour to reach break-even; the last two add the target profit and convert the result into a day rate for quoting. Change any input, such as one more person on the tools or a productive share of 70% instead of 75%, and every line below it moves. That sensitivity is the point: it shows which lever matters most for your firm.

• The firm had been charging 40.00 an hour, so each hour worked cost the business about 5.50 before any profit.
• At 40.00 an hour, 4,830 hours bring in about 193,200 of labour revenue; at 50.55 they bring in about 244,200. The difference is roughly the gap between a small loss and a planned profit.

What is the difference between markup and margin?

Markup is what you add to cost. Margin is the share of the selling price you keep. They are easy to confuse, and confusing them quietly costs money: a 25% markup on cost gives only a 20% margin on the price.

Set your targets as margins, because margin is what your accounts show. When you need the markup that produces a margin, use markup = margin / (1 - margin). The charge-out rate method above divides by (1 - margin) for exactly this reason.

Should you charge the same rate for every type of job?

The charge-out rate is a floor, not the whole pricing strategy. Different types of work carry different risks, payment terms and productivity. A bathroom refit your team has done a hundred times may earn more per crew-week than an extension that runs over. Work with long payment terms or retentions ties up cash, so it needs a higher margin, not a lower one.

Small jobs need special care. A one-hour repair takes far more than an hour once you count travel there and back, booking, invoicing and chasing. In the worked example, a one-hour job really took 2.75 hours of paid time and about 20 of van and parking costs, so the least it could cost was about 159 before tax. That is why many contractors set a minimum job value and a call-out or visit charge.

Market conditions matter too. The Federation of Master Builders and CIOB State of Trade survey for July to December 2025 reported a net +22% of micro and SME building firms seeing rising workloads. Busy markets are when a clear rate and a willingness to say no to poorly paid work pay off most.

How does your charge-out rate connect to cash and hiring?

A correct rate makes a profit on paper. Cash arrives only when clients pay. Deposits, stage payments and a consistent chase process turn the rate into money in the bank. In the UK, for example, the statutory interest rate on late business-to-business payments is 8% plus the Bank of England base rate unless a contract sets another rate, but rules differ by country and some do not apply to homeowners, so check with a lawyer before you rely on them.

Your rate also informs hiring. An employee costs the same whether busy or not; a subcontractor costs more per hour but only when booked. Comparing the two at your real workload gives a break-even point. Cost is not the only test: whether someone is an employee or self-employed depends on the facts of the working relationship. In the United States, the IRS looks at behavioural control, financial control and the type of relationship. In the UK, contractors in the Construction Industry Scheme deduct 20% from registered subcontractors' payments, 30% from unregistered ones and nothing from those with gross payment status. Check your accountant for your own country.

What are the common mistakes when setting a charge-out rate?

• Copying competitors' rates without knowing your own costs.
• Leaving your own quoting and admin time out of overheads.
• Assuming every paid hour is chargeable.
• Adding a markup and calling it a margin.
• Pricing small jobs by the hour on site and ignoring travel and admin.
• Forgetting a replacement fund for vans, tools and plant.
• Calculating the rate once and never again after the crew, vans or overheads change.
• Cutting the rate to win work in a busy market instead of choosing better-fitting jobs.

How often should you review your rate?

Recalculate whenever something structural changes: a new van, a new hire, a new yard, a pay rise, or a clear change in productive share. Otherwise, check it at a monthly business review against actual margins by job type, and in full once a year with your accounts.

When you do raise the rate, do it deliberately. Update every quote template and price list the same week, brief whoever answers the phone, and apply the new rate to new enquiries first so existing clients hear about it from you with notice. Then watch two numbers for the next eight weeks: quote win rate and gross margin by job type. If the win rate falls but margin per crew-week rises, the business is usually better off. If both fall, look at scope clarity, response time and job fit before you look at the rate again.

A spreadsheet makes this a five-minute job: change the overhead list or the hours, and the rate updates. The Small Contractor Business Kit from Bodhih Training includes a workbook that does this, alongside pricing by job type, a cash forecast and debt chasing.
