Cost accounting is a basic and special step in accounting. If you do not understand the nature of cost accounting, it will easily affect the accuracy of financial reports, distort management information, affect operational decisions and even lead to legal violations and tax risks.
The following article by Bizzi will provide a comprehensive view of the cost accounting process and how to control costs in a business.
What is cost accounting? The foundation of cost accounting
Cost accounting is the process of collecting, recording, classifying and summarizing expenses incurred in the production and business activities of an enterprise, in accordance with current accounting regulations. This accounting helps to fully and accurately reflect costs to:
- Calculate the cost of products and services
- Business performance evaluation
Here are some basic concepts related to cost accounting, which are useful if you are preparing training materials, writing an accounting blog, or clarifying financial management processes:
- Cost: Is the total amount of resource expenditure (money, raw materials, labor, services, etc.) that a business spends to achieve a specific goal (product production, service provision, sales activities, management, etc.).
- Cost Classification:
By constituent elements: raw material costs, labor costs, outsourced service costs, etc.
By function: production costs, sales costs, business management costs
According to the relationship with output: fixed costs, variable costs, mixed costs
- Cost of Goods Sold (COGS): Is the total direct cost of producing a product or completing a service. Cost is the final result of the production cost accounting process.
- Cost norms: Is a standard cost level established for a unit of product/service to serve the purpose of control and comparison with actual costs.
- Direct and indirect costs
Direct costs: Directly associated with a product, service, or project (such as raw materials, direct labor)
Indirect costs: Cannot be directly attributed, need to be allocated (such as electricity, machine maintenance, ...)
- Accounting price: Product and material prices are calculated by the business. (Contact: Product prices include expenses).
- Accounting voucher: A form that records details of transactions (including expense transactions).
- Accounting date: Date of recording, statistics and calculation of cost transactions.

What are the characteristics of cost accounting?
Below are the basic characteristics of cost accounting in business - extremely important to understand the correct role, implementation and application in financial management:
Mandatory and compliant with accounting standards
- Cost accounting must comply with current accounting principles and regimes issued by the Ministry of Finance (for example: Circular 200/2014/TT-BTC or Circular 133/2016/TT-BTC).
- This is a mandatory activity for all businesses, to ensure transparency, accuracy and legality.
Expenses are recorded on an accrual basis.
- This means that costs are recorded when they are incurred, regardless of when the money is actually spent.
- For example, when a business receives advertising services in April, the expense is recorded in April, even though it is paid in May.
Recorded in currency
- Although costs may arise from materials, labor or services, when accounting, all are converted and recorded in monetary value (VND or accepted foreign currency).
Costs are classified according to several criteria for analysis purposes:
- By element: raw materials, labor, depreciation, outsourced services, other costs
- By purpose of use: production costs, sales costs, management costs
- By nature: fixed costs, variable costs, direct costs, indirect costs
Is the basis for cost calculation, budget control and decision making.
- Cost accounting helps determine the cost of products and services, serving the purpose of building selling prices and profit planning.
- Helps managers track actual costs against budget, make decisions to adjust or optimize cash flow.
Require valid documents to ensure legality
- All expenses when accounting must have full and valid accounting documents: invoices, payment vouchers, contracts, handover and liquidation minutes, etc.
- This ensures that costs are accepted when settling taxes, avoiding audit risks.
Accounting method
Cost accounting is the way businesses record, classify and track production and business costs. Choosing the right method will help businesses calculate costs accurately and control costs more effectively. Below are the common methods:
| Method | Characteristic | Advantage | Disadvantages |
| Direct costing method | Only include variable costs (costs that vary with output) in product cost. Fixed costs are not allocated to products but recorded separately in the period. |
Easy to control costs according to output fluctuations.
Suitable for businesses that need to analyze profits by product line. |
Does not fully reflect actual costs, especially fixed costs. |
| Full costing/Absorption costing | Include both fixed and variable costs in product cost. | Indicate full cost – required for selling price determination. Used in standard financial reporting. |
It is difficult to determine the real profit per product if the fixed costs are large. |
| Standard costing | Apply cost norms (materials, labor, production costs) to calculate the cost, then compare with reality. |
Helps businesses control costs and analyze variances easily.
Very suitable for mass production, processing industry. |
If the deviation is large, it may cause errors in the report. |
| Job order costing | If the deviation is large, it may cause errors in the report. | Very suitable for businesses that work on orders and do not produce in bulk (printing, interior design, construction, etc.). |
It is time consuming to track each order separately.
|
| Process costing | For continuous production, repetitive processes (eg food, chemicals). Calculate average cost by production stage. |
Suitable for mass production, helps simplify accounting.
