Understanding Job Costing for Bespoke Manufacturers
Job costing is the process of calculating every expense associated with a specific manufacturing job (materials, labour, overheads, and waste) so you can set a selling price that delivers a healthy margin. For bespoke manufacturers, this is particularly important because no two jobs are the same. A fitted kitchen, a set of bespoke shelving, or a commercial shop-fit each require different materials, different labour hours, and different levels of complexity.
Why Overhead Costs Matter
The most common mistake workshops make is underestimating overhead costs. Rent, utilities, insurance, tooling wear, and vehicle running costs all eat into your margin but are easy to overlook when quoting. A good rule of thumb is to apply an overhead percentage of 20–35% on top of your direct labour cost. This calculator helps you factor that in automatically.
Accounting for Material Waste
Waste allowance is another area where many workshops get caught out. Off-cuts, defective boards, and rework can easily add 8–15% to your raw material costs. By building waste into your calculations upfront, you avoid the unpleasant surprise of a job that looked profitable on paper but broke even in practice.
Setting Your Profit Margin
Once you know your true cost, choosing a profit margin becomes a strategic decision rather than a guess. Most UK bespoke manufacturers target margins between 25% and 40%, depending on the complexity of the work and the competitive landscape. Use this calculator to experiment with different margin levels and see how they affect your recommended price.

Frequently Asked Questions
What should I include in my overhead percentage?
Overhead covers all indirect costs that keep your workshop running but are not tied to a specific job. This includes rent, utilities, insurance, equipment depreciation, vehicle costs, and administrative salaries. Most bespoke manufacturers set overhead at 20–35% of direct labour costs.
What profit margin should I target?
This depends on your market and the complexity of the work. UK bespoke manufacturers typically target 25–40%. Simpler, higher-volume work may justify a lower margin, while complex one-off projects should command a higher one to account for design time and risk.
How do I account for waste in my calculations?
Add a waste allowance as a percentage of your total material cost. For standard panel-based work, 8–12% is typical. For projects involving natural timber, stone, or other irregular materials, 12–18% may be more appropriate. This covers off-cuts, defects, and any rework.
