What Is Job Costing?
Job costing is the process of calculating the true cost of a job before you quote a price. It includes labour, materials and overheads, along with your desired profit margin. Without proper job costing, it’s easy to underprice work and reduce your earnings.
Why Job Costing Is Important
Many tradespeople only consider labour and materials when pricing jobs. However, this ignores overhead costs such as fuel, insurance, tools, admin time and vehicle expenses. These costs can significantly impact your profitability if not included.
This calculator ensures you recover all costs and apply a profit margin on top, helping you run a more sustainable business.
Example Job Cost Calculation
Here’s a simple example:
- 2 workers
- 8 hours each

This would produce:
- Labour Cost: £400
- Overhead Cost: £105
- Total Job Cost: £805
- Profit Amount: £161
- Final Quote Price: £966
- Profit Margin: 16.67%
