What is Cost? Classification, Examples, and How to Manage Costs Effectively

Costs are a factor that directly affects a business’s profit, selling price, and operational efficiency. Understanding what costs are, what types exist, and how to control them will help managers make more accurate financial decisions. This article will explain the concept of what costs are, common classification methods, and practical examples for easy application.

1. What are costs?

Costs are a crucial metric shown on the income statement and are used to evaluate a business’s overall performance. According to International Accounting Standards, business costs are defined as “a decrease in economic benefits during the accounting period through a reduction in asset value or an increase in liabilities.”

In simple terms, costs (expenses) include all the amounts a business must pay to achieve its ultimate business goals. 

Determining costs plays a crucial role in business management, as it provides the foundation for business owners to analyze and decide on the most profitable production and business options. Calculating and analyzing costs provides the necessary information to assess the business’s productivity and efficiency.

Additionally, this process helps business owners guide and make flexible decisions in each business stage to optimize business costs. This establishes the ability to shape business strategy and adapt to market fluctuations and the business environment.

2. Why is cost management important in a business?

Cost management is the financial “operating system” that helps a business increase its profit margin, optimize resource utilization efficiency, and create a competitive price advantage, thereby ensuring survival and sustainable development in a volatile business environment.

Here are some of the roles and the importance of cost management in a business: 

Optimize profitability

Effective cost management allows a business to minimize unnecessary expenses, thereby increasing profits without needing to raise product or service prices. At the same time, effectively controlling production, operational, personnel, and marketing costs helps the business maintain its profit margin while remaining competitive in the market.

Improve resource utilization efficiency 

Cost management allows a business to optimize the use of its resources (human, material, financial) to avoid waste. As a result, the business can allocate resources to higher-value activities, improving business performance.

Ensure competitiveness 

With good cost management, a business can keep its product/service prices competitive while still ensuring quality, maintaining, and expanding its market share. Additionally, businesses with lower costs often have an advantage in competitive pricing or creating attractive promotional strategies. 

Aid effective financial decision-making

Cost management provides detailed information about expenditures, thereby supporting leadership in making strategic decisions about investment, expansion, or cutting back on inefficient

activities. Based on cost analysis, the business can also evaluate the benefits of each activity against its costs, helping to improve the decision-making process. 

Manage financial risk 

Tracking and controlling costs helps a business avoid overspending, bad debts, or inefficient use of financial resources, thereby minimizing financial risk. 

Support financial planning and forecasting

Cost management is the foundation for a business to build financial plans, create budgets, and forecast finances for the future. With good cost control, a business can predict financial fluctuations and prepare effective response plans. 

3. General characteristics of costs

First, costs can be seen as the consumption of resources, including both tangible and intangible resources, as well as a business’s materials and labor.

Second, these costs must be closely related to the business’s operational purposes, not the personal expenses of individuals within the organization.

Third, to be considered a cost and reflected on the income statement, the following factors must be met:

• A decrease in future economic benefits, which may be related to a reduction in the value of assets or an increase in the liabilities the business must pay.
• That decrease must be measured accurately and reliably.
• The cost must adhere to the matching principle and correspond with the business’s revenue figures.

Finally, an important characteristic of costs is that they must be quantifiable in monetary terms and determined within a specific period.

4. How many types of business costs are there?

Business costs include all resource expenditures converted into monetary terms, typically classified based on their economic nature, relationship to production volume, or purpose of use to facilitate cost calculation and profit control. The following are common methods for classifying costs:

4.1. Classification of production costs by economic nature (cost elements)

To support the organization and management of costs based on their economic content and point of origin, costs are often classified by elements. This method helps in establishing and analyzing working capital norms, as well as in preparing, reviewing, and analyzing cost estimates.

According to current regulations in Vietnam, costs are divided into 7 main elements:

• Raw materials and materials: Includes the value of main raw materials, auxiliary materials, spare parts, and tools used in the production and business process.
• Fuel and power: Includes the amount of fuel and power used in the production and business process.
• Salaries and allowances: Reflects the total amount of salaries and allowances payable to employees.
• Social insurance, health insurance, and trade union fees: Includes contributions for social insurance, health insurance, and trade union welfare funds, calculated as a prescribed percentage of total salaries and allowances.
• Depreciation of fixed assets: Reflects the total depreciation of fixed assets to be recorded for the period, applicable to all fixed assets used in the production and business process.
• Cost of outsourced services: Includes the cost of outsourced services used in the production and business process.
• Other cash expenses: Reflects the total of other cash expenses not included in the previous elements, used in the production and business activities during the period.

4.2. Classification of production costs by economic purpose (cost items)

To facilitate the process of calculating product costs, costs are often classified into items based on their purpose and how they are allocated to each object. In this process, the total cost of a product typically includes 5 main cost items:

Direct material costs: Includes all costs of raw materials used directly in the production and manufacturing of products, labor, and services.

Direct labor costs: Includes salaries and direct allowances for production workers, as well as deductions directly related to salaries such as trade union fees, social insurance, health insurance, etc.

Manufacturing overhead: Includes costs related to supporting and managing production within the scope of production workshops and teams. Specifically:

• Workshop employee costs: Includes salary costs, payables, and salary-related deductions for workshop and production team employees.  
• Material costs: Includes the cost of materials used jointly by the production workshop for the purpose of supporting production management.
• Tool costs: Includes the cost of tools and equipment in the workshop used to support production and production management.
• Fixed asset depreciation costs: Includes all depreciation costs of fixed assets used in the production workshop.
• Cost of outsourced services: Includes costs of outsourced services used in the process of supporting and managing production.
• Other cash expenses: Includes direct cash payments used for supporting and managing production in the workshop.

Selling expenses: Costs related to the product consumption process, including advertising, delivery, transactions, sales commissions, sales staff, and other costs related to storing and selling the product.

General and administrative expenses: Includes costs related to supporting and managing business operations that are general in nature for the entire enterprise, such as administrative staff costs, administrative material costs, depreciation of shared fixed assets, various taxes and fees, and entertainment and conference expenses.

4.3. Classification of production costs by cost function

• Direct material costs: Includes the costs of both main and auxiliary raw materials used directly to manufacture the product.
• Direct labor costs: Includes all costs related to direct labor in production, including salaries, salary-related deductions, and salary-like allowances for workers directly involved in the production process.
• Manufacturing overhead: Includes all costs related to production support and management activities within the scope of a workshop or team. This can include workshop employee costs, raw material costs, tool and equipment costs, depreciation of equipment and workshops, outsourced service costs, and other cash expenses related to the production process.

4.4. Classification by cost content

• Raw material costs: Includes costs incurred during the business period related to the procurement of raw materials for the production process.
• Labor costs: Includes salaries, bonuses, and payroll deductions charged as expenses during the period, serving the production process.
• Depreciation costs of fixed assets: The value of wear and tear on fixed assets used during the business’s production period.
• Outsourced service costs: Costs incurred from using external services in the production process.
• Cash expenses: Includes expenses paid in cash during the business process.

4.5. Classification of costs by relationship to production volume

• Fixed costs: Costs that do not change in total with fluctuations in the unit’s level of activity.
• Variable costs: Costs that change in proportion to the unit’s level of production activity.

4.6. Classification of costs by relationship to profit

• Period costs: Costs incurred during a business period that affect the company’s profit. Includes both selling expenses and general administrative expenses.
• Product costs: Costs incurred in the process of creating the value of materials, assets, or finished goods. They are considered a type of current asset for the business and only become an expense when the product is sold.

4.7. Classification of costs by cost object and cost accumulation method

• Direct costs: Costs that are incurred and can be directly traced to a specific cost object.
• Indirect costs: Costs related to multiple cost objects, which must be accumulated and then allocated according to appropriate criteria.

5. The relationship between costs and business cash flow

In business, profit doesn’t guarantee survival, but cash flow always determines operations. Costs are a factor that directly impacts cash flow, causing a business to either maintain a “healthy” state with positive cash flow or face risks if costs spiral out of control.

5.1. The impact of costs on short-term cash flow

Expenses such as raw materials, employee salaries, office rent, marketing, etc., will immediately reduce cash flow for the period. If revenue and expenses are not balanced, a business can easily fall into a situation of “profit on paper but lacking cash to operate.”

For example: a sales company has high revenue but excessive accounts receivable, while operating costs must still be paid monthly → negative cash flow.

5.2. Investment costs and their impact on long-term cash flow

Large expenditures such as purchasing machinery, investing in technology, or expanding branches often “consume” a significant amount of cash flow in the short term. However, these form the foundation for creating long-term value. For instance, a manufacturing company invests in an automated production line: cash flow is immediately negative, but after a few years, labor costs decrease and productivity increases → more stable positive cash flow.

5.3. Managing costs to maintain positive cash flow

To maintain positive cash flow, businesses need to create clear budgets, forecast cash flow, and closely monitor unusual expenses. Cash flow management tools like accounting software, ERPs, or periodic cash flow reports help managers be more proactive. Cutting costs is not always the solution; sometimes, simply changing the timing of expenditures or renegotiating payment terms can help cash flow “breathe” more easily.

6. Common mistakes in recording costs

• Confusing costs with cash outflows

In many cases, business owners find it difficult to distinguish between the two important concepts of costs and cash outflows. Some people tend to treat all payments as costs, leading to a common mistake of considering all prepayments to suppliers as an expense in a single period, instead of allocating them correctly according to accounting methods.

• Confusion related to recording asset depreciation costs

In the early stages, newly established or inexperienced businesses often make mistakes related to recording asset depreciation costs. Some businesses have a habit of recording the entire value of an asset as an expense in the period it was purchased or not including it in production costs during business operations.

• Not fully recording all business expenses

In many cases, businesses may overlook actual expenses that have been incurred and meet all the conditions for cost recognition. A typical example is not including the business owner’s salary in administrative expenses. This can lead to distortions in the cost structure and an inaccurate assessment of the business’s profitability.

• Confusing costs with the value of purchased inventory

Another common mistake is failing to distinguish between the value of purchased inventory and costs. For example, recording the entire value of raw materials imported into the warehouse as a production cost in one period, when in reality, it only becomes a cost when the raw materials are used in production.

• Recording costs only upon receiving an invoice

Some businesses may mistakenly believe that costs can only be recorded upon receiving an invoice from the seller. However, a cost must be recorded when it meets three conditions: it reduces the value of an asset or increases a liability, it can be reliably determined, and it adheres to the matching principle with revenue. This is crucial for ensuring accuracy and transparency in the business’s financial management.

7. Related concepts – fees and charges

7.1 Information about fees

According to Article 3, Clause 1 of Law No. 97/2015/QH13, a Fee is defined as an amount of money that organizations and individuals must pay for the primary purpose of offsetting costs and for service when receiving public services from state agencies, public service units, and organizations authorized by competent state agencies to provide them. The fees are detailed in the List of Fees issued with this Law.

Example: Fee for providing business information, fee for certifying the origin of goods, etc.

The main purpose of collecting fees is to offset costs and serve the community when individuals and organizations receive public services from authorized agencies and organizations.

Determining the fee level is a process based on the principle of ensuring cost recovery and must reflect the State’s socio-economic development policies in each period. The determination of fee levels must also comply with the principles of ensuring fairness, publicity, transparency, and equality in the rights and obligations of citizens.

The competent units for collecting fees include state agencies, public service units, and organizations authorized by competent state agencies. After collecting the fees, these units will:

• Deduct if there are operating costs covered by the fee revenue;
• Retain a portion or all of the collected fee amount to cover the operating costs of providing the service. This is usually done based on an estimate approved by a competent state agency for public service units.
• The remainder will be submitted to the State Budget.

7.2 Information about charges

According to Clause 2, Article 3 of Law No. 97/2015/QH13, a charge is a fixed amount of money that organizations and individuals must pay when receiving public services from a state agency, serving state management work as specified in the List of Charges issued with this Law.

Example: Residency registration charge, national ID card issuance charge, etc.

The purpose of a charge is not to offset costs. The level of the charge is determined on the basis of ensuring fairness, publicity, transparency, and equality in the rights and obligations of citizens.

State agencies are the only units authorized to collect charges, and these collections are subsequently submitted in full to the State Budget.

The cost indicator is a crucial factor in a business, and business owners need to monitor it regularly and continuously. Tracking the cost situation by period, by office/branch, by each cost item, and comparing incurred costs will help business owners get an accurate and timely overview, thereby making appropriate decisions.

8. Some suggestions for minimizing costs and increasing profits in a business

Every business wants to optimize its expenses to reduce this figure as much as possible. In the current era of digital transformation, business management software has emerged to help businesses manage certain stages of their operations. As a result, operations are managed in a unified, logical, and fast manner, saving manpower, preventing losses, and reducing unnecessary costs.

In addition, many businesses today have integrated information technology into their activities, such as e-invoices, online accounting software, e-taxes, e-insurance, remote contract signing, etc.

Other ways to reduce costs include optimizing material and facility costs and limiting unnecessary expenditures.

9. Frequently Asked Questions About Costs

How to quickly distinguish between Costs and Expenditures?

– Costs (Expenses): The value of resources consumed to generate revenue within a period (payment may not have been made immediately, e.g., depreciation).

– Expenditures (Expenditure): The actual act of disbursing cash or assets to purchase something (it may not be recorded as a cost immediately, e.g., prepaying rent for one year).

Why does a business show a profit on its reports but run out of cash in reality?

This is the “phantom profit, real loss” phenomenon, caused by the mismatch between revenue/costs and cash flow. The business might recognize revenue but has not yet collected the cash (large accounts receivable), or recognize depreciation expenses (a non-cash expense) while having to repay loan principals (a cash outflow that is not recorded as a cost).

Fixed costs vs. variable costs: which is more dangerous during market fluctuations?

Fixed costs (rent, fixed salaries) are more dangerous. When revenue declines, these costs remain the same, putting immense pressure on cash flow. Meanwhile, variable costs automatically decrease in line with business volume.

Does cutting costs always lead to sustainable profit growth?

Not necessarily. If drastic cuts are made to value-creating costs (such as training, quality of raw materials, customer care), the business will suffer from reduced productivity and lose customers in the long run. Sustainable profit growth comes from optimizing wasteful spending, not cutting investment costs.

What is the most effective way to control hidden costs?

The best way is to digitize your management processes. When activities from HR and finance to production are carried out on a unified software platform, wasteful expenses (downtime, data errors, material loss) will be transparently tracked through real-time reports for timely resolution.
