If you want to understand the business deeply, you need to know the costs well first because they are the foundation for decisions about pricing, investment, and growth planning. Today, let's talk about fixed costs and variable costs, which are very important in business management.

Starting with fixed costs, these are expenses that must be paid whether the business sells a lot or a little, such as office rent, employee salaries, insurance, loan interest, or depreciation of equipment. Any cost that is fixed is something that must be paid regardless of whether the business is active or not because it is a long-term obligation that must be continuously borne.

On the other hand, variable costs increase as production or sales increase and decrease when production decreases, such as raw materials, direct labor wages, energy costs, packaging, and transportation. These types of costs are more flexible because they follow the volume of production.

Why is it important to distinguish clearly? Because knowing which costs are fixed and which are variable helps us set appropriate product prices. If the business sells at a price that does not cover fixed costs, it will lose money even though it still has to pay rent, salaries, and other expenses.

Analyzing mixed costs (including both types) is therefore crucial for decision-making in areas such as machinery investment, production planning, or assessing how market changes will impact profits. Sometimes, when direct labor costs are high, a business might decide to invest in machinery to achieve more stable fixed costs.

To manage a business well, you must understand both fixed and variable costs because they affect competitiveness and financial stability. Whether it’s controlling costs, planning production, or analyzing risks, all of these depend on a deep understanding of the cost structure of the business.
