What is cost price?
A cost price is the sum of the expenses incurred by a company to produce and distribute a good or service. By subtracting the turnover generated by this good or service from the cost price, we can evaluate its profitability.
In other words, costing gives you an accurate view of what each product or service you offer actually costs, helping you set your selling prices and maximize your profitability.
The importance of cost price
Cost of living is a key indicator for any company looking to control its finances and optimize its margins. Knowing how to calculate and adjust your cost of living is essential to identify areas where you can save money, optimize your processes and ultimately, strengthen the profitability of your company.

Differentiate between direct and indirect costs
To correctly calculate your cost price, it is crucial to distinguish between direct and indirect costs.
Direct costs include everything that goes into producing a good or service. This includes raw materials, labor used specifically to create the product, and any other resources directly involved. For example, in a manufacturing plant, this might be physical components, specific machinery, or the time of employees responsible for assembly.
Indirect costs, on the other hand, concern the distribution and marketing of a good or service. These can include transportation costs, packaging costs, energy costs, administration costs, rental of premises or even equipment maintenance. These costs can be difficult to attribute precisely to each unit produced, but their impact on your margins should not be underestimated.
By correctly categorizing these two types of costs, you will be able to establish a solid basis for accurately calculating your cost price. This also allows you to better visualize where expenses are concentrated and identify areas for optimization.
How to calculate unit cost price
The calculation of unit cost is based on a simple but essential formula:
Unit cost price = Total direct and indirect costs / Number of units produced
Concrete example: Let's say you manufacture chairs. The raw materials (wood, screws, glue) and associated labor cost $50,000 for a production of 1,000 chairs. Your indirect costs (electricity, rent, maintenance) are $10,000. So the cost per chair calculation would be:
Cost per chair = 50,000 (direct costs) + 10,000 (indirect costs) / 1,000 = $60 per chair
This simple calculation allows you to set a selling price that not only covers your expenses but also generates a profit margin. However, the reality can be more complex, especially in cases of multi-level assemblies or products with multiple components. This is where an ERP can really make a difference, by automating cost tracking and ensuring that all necessary data is taken into account, from the beginning to the end of the production process.
Cost price for a complex assembly
When it comes to complex assemblies, calculating cost becomes trickier. In these situations, there are often multiple levels of production or assembly, each with its own associated costs. For example, if you are manufacturing a product with multiple subcomponents that are manufactured separately, it is important to properly allocate the costs to each stage.
Example of a complex assembly: Consider an industrial machine composed of several modules. Each module has its own direct costs (electronic components, wiring, labor) and indirect costs (electricity, machine tool maintenance). To calculate the total cost of the machine, you must first calculate the cost of each module separately and then add them together to obtain the overall cost.

Optimizing your profitability with cost price
Once your cost price is well calculated, the next step is to identify optimization levers to improve the profitability of your business. Here are some strategies to reduce your costs and maximize your margins:
- Reduction of direct costs
Look for suppliers with better terms, negotiate volume discounts or explore alternatives to the raw materials used. Optimizing labor productivity or automating certain production processes can also reduce your direct costs. - Optimization of indirect costs
Analyze your operational expenses: energy, logistics, inventory management. For example, better inventory management through an ERP can reduce storage costs and minimize losses related to expired or obsolete inventory. - Automation and process management via ERP
By adopting an ERP, you can not only automate your cost calculation, but also quickly identify the highest cost items. This allows you to react in real time to fluctuations in raw material prices or changes in demand and optimize your margins without delay. - Identify the right price using unit cost price
Once you have established your unit cost, it becomes easier to set a competitive selling price. This must not only cover all costs, but also generate an acceptable profit margin based on the market and competition. This approach allows you to adjust your prices more precisely and ensure that you are not selling your products or services at a loss or below the desired margins.
By following these paths, you can transform your cost price calculation into a real lever for continuous improvement. The ultimate goal is to use this data to make informed decisions, reduce your production costs and improve your margins while ensuring optimal service or product quality.
