Just realized that cost structure in business is really important. Whether it’s fixed costs or variable costs, they truly affect a business’s decision-making and competitiveness.

In fact, fixed cost means costs that do not change with the level of production, and you have to pay them no matter how much the business produces or sells. It’s like a burden you carry with you—unavoidable. For example, land rent, employee salaries, insurance, loan interest, or depreciation of equipment. All of these occur every month or every year, whether sales are high or low.

As for what “fixed cost” means in Thai, it’s simply “fixed costs” (ต้นทุนคงที่). This is different from variable costs, which change according to the level of production—for example, raw materials, direct labor costs, packaging, transportation, or sales commissions. The more you produce, the higher these costs become.

For financial planning, understanding what fixed costs are and what types they have is extremely important, because it helps you calculate total costs accurately and apply that information to set the right prices for products or services.

Combining fixed costs and variable costs gives you a clear overview of the overall costs you need to bear—necessary for making decisions about investments, production planning, cost control, and evaluating competitiveness.

This topic might sound complicated, but once you understand it, it really helps—whether it’s business decision-making or planning for long-term growth. Knowledge of costs is the foundation of effective business management.
