This calculator provides a planning estimate only. It is not personalised tax, legal or financial advice. Your actual rate may need to be higher depending on your market, VAT position, pension needs, tax liabilities and commercial risk.
A better rate starts with the right assumptions
Pricing only from your desired salary can leave a gap. A sustainable rate also pays for the time and costs required to run the business.
Set an income goal
Choose the annual amount you want the business to generate for you before your personal tax and National Insurance.
Add every business cost
Include subscriptions, insurance, professional fees, equipment, premises, vehicle costs and marketing.
Protect non-billable time
Quotes, bookkeeping, training, sales and administration take time but are rarely charged directly to a client.
Why billable hours matter
A 35-hour working week does not usually mean 35 chargeable hours. Sole traders also answer enquiries, prepare quotes, chase invoices, buy materials and keep records. If those hours are ignored, your apparent hourly rate can be misleading.
For many service businesses, a billable percentage between 50% and 75% is a useful starting point. Your figure depends on the work. A consultant on a long project may have a higher percentage than a tradesperson travelling between short jobs.
What should your costs include?
List both obvious expenses and irregular costs. Common examples include accountancy, bookkeeping software, phone bills, insurance, fuel, tools, licences, advertising, subcontractors and equipment replacement.
Convert quarterly or one-off costs into an annual total. If you use something partly for business and partly personally, ask your accountant what proportion may be allowable rather than assuming the full amount.
Turn the result into a commercial rate
The calculated figure is a minimum planning rate, not a price ceiling. Experience, urgency, specialist knowledge, local demand and the value delivered can all justify a higher rate.
Build in a contingency
A buffer can protect your cash flow when a client pays late, equipment fails or demand changes. It can also provide room for training and future investment. The default 10% is a starting point rather than a universal rule.
Choose hourly or day pricing
Hourly pricing suits uncertain workloads and short jobs. Day rates are often clearer for project work. Fixed fees can reward efficiency, but only when the scope and change process are well defined.
Review your rate regularly
Recalculate when costs rise, your VAT position changes, your service becomes more specialised or your available billable time falls. A quarterly review helps prevent a profitable-looking workload from becoming underpriced.
Keep your pricing clear
State whether your quote is hourly, daily or fixed. Explain what is included, when payment is due and how additional work will be approved. Clear written terms reduce uncertainty for both you and the client.
Remember tax and VAT
The calculator does not deduct Income Tax or National Insurance. It also excludes VAT. If you are VAT registered, your customer invoice may need VAT added to your net price. Keep a separate tax reserve and review it against current figures.
Use tidy records
Record income, expenses and time consistently. Good records show which services and customers produce a healthy return. They also make invoicing, Self Assessment and year-end discussions easier.
Who can use this calculator?
This free UK calculator is useful for freelancers, consultants, designers, cleaners, photographers, tutors, tradespeople and other self-employed professionals. It works best for service businesses that sell time or use time as the basis for quotes.
If you sell products or carry substantial materials, stock or subcontractor costs, treat those direct costs separately and check that your margin covers them. The hourly rate should reward your labour and contribute to business overheads.
Sole trader hourly rate FAQs
What hourly rate should a sole trader charge?
Your rate should cover business costs, non-billable working time, your target income and a suitable buffer. Market demand and the value of your work may support a rate above the calculator’s minimum.
What is a realistic billable percentage?
It varies by business. Many service providers start with 50% to 75%, then replace the estimate with actual time records. A lower percentage increases the hourly rate needed to reach the same revenue target.
Is tax included in the calculation?
No. The result is a business revenue planning figure before personal Income Tax and National Insurance. Your tax depends on your profits and circumstances.
Does the rate include VAT?
No. If you are VAT registered, VAT may need to be added to the price you charge. VAT collected is not business income.
How is the day rate calculated?
The indicative day rate is the hourly rate multiplied by 7.5 billable hours. Adjust your quoted day rate if your working day, travel time or service model is different.
Can tradespeople and freelancers use the tool?
Yes. It is suitable for most time-based services. Tradespeople should also add materials, travel and subcontractor costs where relevant to each job.
