Production Cost Calculation: Real Order Margin

Key points at a glance:

To assess the profitability of orders objectively, it is important for a manager to distinguish between production and operating costs. If management accounting in production is carried out using the method of averaging costs at the end of the month or in standalone Excel spreadsheets with manual data entry, the company is presented with a distorted margin, where profitable items offset loss-making ones.

1. Key definitions: production and operating costs

To avoid confusion in terms, let's distinguish the key concepts of production accounting:

Production Cost (Production Cost / Cost of Goods Manufactured)

These are direct and indirect costs associated exclusively with the production process within the shop. They are tied to each batch and unit of goods produced. While the goods are in stock and not sold, these costs are capitalized (remain in the assets of the enterprise as finished goods).

The production cost includes three main blocks:

1. Direct material costs: raw materials, supplies, purchased semi-finished products that become the basis of the product.

2. Direct labor costs: the salary of workers (with deductions/EUC) who directly produce this product (carpenters, turners, seamstresses).

3. General production costs (GPC): costs for organizing and managing production within the shop (depreciation of shop machines, electricity for equipment operation, salary of the shift foreman/shop manager, equipment repair).

Operating Cost / Total Cost

This is a broader concept that includes production costs + all other costs associated with the current activities of the enterprise for a certain period (excluding financial costs, such as interest on loans, and income tax).

It shows how much it cost not just to manufacture the product, but also to maintain the company that developed it, issued the documents, promoted it, and sold it.

In addition to production costs, the following are added here:

Administrative expenses: salaries of the director, accountants, lawyers; rent and heating of the head office, stationery, communication and IT infrastructure costs.
Sales costs (marketing and logistics): targeted and contextual advertising, packaging of finished products in sales warehouses, delivery to the client, salaries of sales managers, maintenance of branded stores/showrooms.
Other operating expenses: bad debts, inventory impairment losses, operating leases, etc.

Example: furniture factory (batch of chairs)

Let's see how the money is distributed using the example of a batch of 100 wooden chairs (of which 96 turned out to be of good quality and 4 were defective):

1. Costs that form the production cost of a batch and 1 chair:

Wood (oak), varnish, screws, glue — 100 UAH per chair (direct materials).
The salary of the carpenter who sawed and assembled the chair is 50 UAH (direct salary).
Depreciation of the sawing machine in the workshop and electricity - 20 UAH (ZVV).
The salary of a shift foreman in the shop is 10 UAH (ZVV).

Total production cost of the batch (including defects): UAH 18,000 .

Production cost of 1 high-quality chair (taking into account 4% defect): UAH 187.50 (UAH 18,000 / 96 high-quality chairs).

2. Costs added to form operating costs:

Delivery of the chair by truck to the buyer's warehouse — 15 UAH (sales costs).
Targeted furniture advertising on Instagram — 10 UAH (final for 1 unit) (sales costs).
The share of the salary of the plant director and chief accountant is 25 UAH (administrative expenses).
Rent of the office where the sales department is located — UAH 5 (share in terms of the total number of products for the month) (administrative expenses).

Total added operating costs for 1 chair: 55 UAH .

3. Final calculation:

Production cost of 1 high-quality chair: UAH 187.50.
Operating (full) cost of 1 high-quality chair: 187.50 UAH + 55 UAH = 242.50 UAH .

💡 Why is this critical for a director or owner?

If the director sells a chair for 210 UAH, focusing only on the planned production cost (180 UAH), he will think that the factory is operating in the red (+30 UAH). But taking into account the shortage and real operating costs (242.50 UAH), the company actually suffers losses of 32.50 UAH on each chair , since the income does not cover the maintenance of the office, accounting, and advertising.

2. Why spreadsheets and accounting programs do not provide operational management of the shop

To make the right decisions, the manager needs cost data at the time of the transaction. However, classic tools have significant limitations:

Features of working with Excel. Excel is a great and flexible tool for financial modeling, analytics, and primary calculations. However, when scaling production, stand-alone spreadsheets lack automatic synchronization with the shop and warehouse in real time. Dynamic changes (the appearance of defects, changes in line load) require constant manual data entry, which creates the risk of human error and information inconsistency between departments.
Accounting features. Accounting systems (such as BAS) are designed primarily for financial and tax reporting. Depending on the settings and accounting policies, the accurate calculation of the full cost, taking into account all overhead costs (rent, depreciation, administrative staff) is often tied to the closing of reporting periods. Production, on the other hand, needs a tool for operational management and accurate facts for each batch in real time.

Comparison of cost accounting tools

Criterion	Spreadsheets	Accounting	Management systems (using the example of CRM Genesis solutions)
Main purpose	Flexible financial modeling, calculations and analytics	Financial and tax reporting of the enterprise	Operational control of the shop, dispatching and batch margin
Data entry	Manual input (high risk of human error)	Based on primary documents and acts	Automatic or semi-automatic fixation at stages/operations
Cost breakdown	Depends on the complexity of the model built	By company, divisions or nomenclature groups	Detailed: order, batch, shift, worker
Workshop operating hours	Offline (requires manual update)	Ex post factum (after documents are processed)	In real time (at the time of the operation)

3. 7 mandatory elements of a production management system from CRM Genesis

To see real, not imaginary, marginality, a modern operational accounting system (using the example of solutions implemented by the CRM Genesis team) must automate 7 key elements:

Digital technical charts (BOM). Clear basic product composition and sequence of technological operations.
Addressed write-off of materials. Consolidation of raw materials and actual shortages for a specific order on the day of release.
Accounting for operating time. Recording real-time equipment operation and personnel workload.
Automatic overhead allocation. Correct allocation of electricity or depreciation costs (for example, proportionally to the operating time of equipment for a specific order).
Plan-actual analysis of batches. Instant detection of deviations of actual costs from the established norm.
Batch accounting of raw materials. Writing off materials at the actual price of a specific purchase, rather than at the "average price for the warehouse."
Work in Progress (WIP) Accounting. Transparent control of residues and semi-finished products that are between technological processes.

4. Quick test: are you calculating the real cost?

The 20-Order Rule: Take the last 20 completed orders. Try to collect the input parameters of the production cost (raw materials, workers' salaries, depreciation, electricity, scrap) for each of them within one hour.

If you confidently collect accurate figures for all 20 orders in 1 hour - congratulations, you are doing well with operational management! Otherwise, there is no managed cost at the enterprise yet, and pricing decisions are made blindly.

Take the ready-made template for calculation:

To avoid wasting time creating formulas in spreadsheets, use our ready-made Interactive template “Cost Cost Quick Test: 20 Orders” in Google Sheets . Enter the parameters and the dashboard will automatically calculate the production cost of the batch, the cost of the unit taking into account defects, and the final margin.

5. Step-by-step plan for implementing cost accounting on a pilot batch

Implementing automated accounting at once across the entire plant is risky. The optimal way is to work out the full cycle on one product or one production line (pilot batch).

Goal: to improve the accuracy of technical charts, train staff in the discipline of recording, and obtain the first transparent planned-actual cost without stopping the entire enterprise.
What's at the output: a ready-made, proven methodology that can be scaled flawlessly to all other SKUs.

4 actions to take in 1 week:

We prepare the first 2 points in advance (this takes 1-2 hours)

Basic reference books. Daily task: organizing the nomenclature of raw materials, finished products, and units of measurement.
Pilot technical charts. Daily task: creating accurate regulatory specifications (BOM / Bill of Materials ) and route maps for one selected product. Conducting control measurements of time and material consumption.

We do 3 and 4 systematically every day for a week:

Recording discipline. Daily task: setting up daily recording of output, scrap, time worked and raw material consumption directly during the task. Masters learn to enter data immediately, not “sometime later.”
Plan-Actual Analysis. Daily task: summarizing data from the first test batch, comparing the estimated cost with the actual fact, analyzing the causes of deviations, adjusting processes, and preparing for system scaling.

When you have a complete and accurate accounting of the production cost of each batch and unit, you can proceed to calculating the operating (total) cost , adding administrative and sales expenses for the period. We will describe how to do this correctly in a separate article, so subscribe to us so as not to miss a new article.

For companies that want to test this approach without risk, CRM Genesis experts offer the "1 Day in Production" format - an express audit of the current situation in the shop and recommendations for improving processes.

The service itself is free, and the departure conditions depend on the location:

Kyiv and the region (up to 30 km from Kyiv): a specialist's visit is completely free.
Other regions of Ukraine (more than 30 km from Kyiv): the customer covers only the actual travel and accommodation costs of the specialist.

6. 6 typical mistakes when calculating cost

Overall cost averaging. Consolidation of all company costs into a "single basket" at the end of the period without reference to specific batches of orders.
Equal distribution of overhead costs. Charging the same share of depreciation or electricity for simple products and technologically complex items.
Defect outside the technical sheet. Writing off spoiled raw materials to the company's general losses instead of reflecting losses on the specific batch where this defect occurred.
Using the planned purchase price. Calculating the cost at "desired" prices instead of taking into account actual invoices from suppliers.
Ignoring changeover time. Not taking into account equipment downtime and resource costs when switching lines from producing one product to another.
Errors in accounting for labor costs. Calculating wages at average or planned rates instead of recording the actual time worked by workers for a specific order.

Frequently asked questions

Why is average cost dangerous for business?

The average cost is dangerous because it completely distorts the real marginality of individual batches. With this approach, high-margin products actually subsidize hidden loss-making positions that should have been discontinued or increased in price long ago. CRM Genesis analysts recommend completely abandoning the “boiler” method in favor of daily batch cost accounting.

Does a specialized production system replace an accounting program?

No, a specialized production system does not replace accounting software, but works in conjunction with it. For example, the CRM Genesis team sets up seamless integration between the shop's operational circuit (where technical charts, production processes, and defects are recorded in real time) and the accounting program for tax reporting.

How to correctly distribute workshop overhead costs?

Directly tie them to an objective cost factor — most often to equipment operating time (machine hours) or worker time on a specific operation, rather than dividing them equally among all products.
