Hourly Billing Rate Calculator
The hourly billing rate is the price a trades business charges customers per working hour. It covers labor costs, overheads, owner salary, profit, and risk allowances and must generate enough to cover all operating costs and a reasonable return.
Based on the Chamber of Crafts costing scheme: total costs ÷ productive hours × (1 + profit% + risk%).
How do you interpret the result?
The calculated hourly billing rate is your minimum rate for covering all costs. If your current hourly rate is below this, you are working below cost. The net billing rate is your target price before VAT. Market conditions and customer mix determine whether it can be achieved.
Not included: material surcharge, subcontracted services, and project-specific line items.
