How to Calculate Cost Price?

What is the cost price?

The cost price is the total cost incurred by a company or organisation to produce a good or provide a service, traced to a unit produced or sold.

It includes all direct costs (raw materials, labour directly linked to production) and indirect costs (rent, electricity, administration, marketing, depreciation).

Put simply: this is what the product or service actually "costs" the company before it is sold.

Controlling your cost price allows you to:

• Set a consistent selling price;

• Avoid selling at a loss;

• Analyse actual profitability;

• Explore costs by product/service, activity, machine, customer, marketing strategy, etc;

• Analyse the feasibility and profitability of future projects;

• Establish a value for products / work in progress and finished products;

• Parameterise indirect costs in the various manufacturing systems (ERP / MRP);

• Pilot the company's performance.

Difference between cost price, selling price and gross margin

These concepts are often confused, even though they play very different roles in management.

• Cost price: Sum of all the expenses required to produce a good or service. It is an internal figure, specific to the company.

• Selling price: Amount invoiced to the customer. It depends on the market, competition, perceived value and sales strategy.

• Gross margin: Difference between selling price and cost price. It measures the direct profitability of a product or service.

A profitable business is one where the selling price is higher than the cost, with a sufficient margin to cover its financial objectives.

Costing: case of a product vs. case of a service

The costing principle is the same, but its composition varies according to the activity.

For a product (industry, commerce, craft)

The cost price is mainly based on :

• raw materials;

• production labour;

• manufacturing costs;

• storage and logistics;

• machinery depreciation.

• sales, administration and financial expenses.

For a service (firm, consultant, service SME)

The cost price is often dominated by :

• work time (salaries, social charges);

• overheads (premises, software, insurance);

• sales, administration and financial expenses.

In services, time is becoming the main unit of cost, making the calculation even more strategic.

What is the costing formula?

The simplest and most widely used formula for calculating a unit cost is :

Cost = (Direct costs + Indirect costs)/(Quantity produced)

Explanation line by line

Direct expenses

These are costs directly linked to the production of a good or the provision of a service.

Examples : raw materials, direct labour, consumables, production-related transport.

Indirect costs

These are costs that are necessary for the operation of the business, but cannot be directly attributed to a product/service without a breakdown.

Examples : rent, electricity, administration, marketing, insurance, depreciation.

Quantity produced

This is the number of units actually produced (or sold, if more relevant) over a given period.

Examples : 100 units manufactured, 40 projects delivered, 120 billable hours, 300 services completed.

The result gives a unit cost: what 1 unit (1 product, 1 service, 1 hour, 1 mandate...) costs on average.

Example in figures

Let's imagine an SME that manufactures products and produces 100 units over the course of a month.

• Direct costs: $3,500

• Indirect costs: $1,500

• Quantity produced: 100 units

Cost = (3500+1500)/100 = 5000/100 = 50

Cost per unit = $50 per unit.

The main costing methods

The choice of method depends on the type of activity, the level of precision required and the management objectives.

Here are the three methods most commonly used in companies.

The full cost method

The full cost method involves including all expenses, whether direct or indirect, fixed or variable, in the cost calculation.

Indirect costs are allocated using distribution keys (surface area, hours worked, volume produced, sales, etc.).

This is the most "classic" and widespread method.

Benefits

• A comprehensive and realistic view of the real cost.

• Allows you to check whether a product or service covers all expenses.

• Indispensable for avoiding selling at a loss.

• Often required for comprehensive financial analyses.

Limits

• Sometimes arbitrary allocation of overheads.

• Less suited to fine-grained analysis of profitability by product.

• Little reactive for quick decisions.

The variable cost method

The variable cost method retains only those expenses that vary directly with the level of activity (raw materials, variable labour, commissions, production-related energy).

Fixed costs (rent, administration, insurance) are excluded from the unit cost calculation and analysed separately.

It highlights the variable cost margin.

Interest in short-term decisions

This method is particularly useful for :

• Accepting or refusing a one-off order.

• Analysing the impact of a change in volume.

• Taking quick decisions (promotion, temporary price).

• Calculating a break-even point.

On the other hand, it does not show whether the business covers all its fixed costs over the long term.

The ABC method (Activity-Based Costing)

is based on a different logic: costs are not allocated directly to products, but by activity (e.g. logistics, customer support, production, sales management).

Each activity consumes resources, and it is this consumption that is then allocated to products or services.

It provides a much more accurate and detailed picture of costs.

From theoretical calculation to a truly profitable decision

There are many tools available today for calculating costs: spreadsheets, accounting software, ERP, etc. These solutions are useful and are often an essential first step.

But in the reality of a business, the real challenge is not to make a calculation, but to know whether that calculation is accurate, complete and really usable for making the right decisions. The quality of the data, the choice of activities and the identification of the right allocation units are all important factors in the costing methodology.

Incorrect costing (e.g. overlooked expenses, poor allocation, unrealistic volumes) can distort :

• Your selling prices;

• Your actual margin;

• Your strategic decisions

• And ultimately, the financial health of your business.

It is precisely to avoid these blind spots that Mallette's experts work with you to assess the cost of your products and services, taking into account your operational reality, your cost structure and your business objectives.

Thanks to a structured and professional analysis, you'll get a reliable vision that's aligned with your company's real performance, far beyond a simple theoretical calculation.
