I just noticed that many people still don’t understand the difference between fixed cost and variable costs, which is very important if you want to manage your business successfully.

Put simply, fixed costs are costs that do not change no matter whether you sell more or less. For example, office rent, salaries of permanent employees, insurance, and loan interest. These costs have to be paid every month whether or not the business has income.

Variable costs are the opposite. They increase or decrease depending on the volume of production or sales. The more you produce, the higher the costs. Examples include raw materials, direct labor, packaging, transportation, or sales commissions.

Why do you need to know this? Because understanding fixed costs and variable costs helps you make better decisions—whether it’s pricing products, planning production, or reducing costs appropriately.

Think about it: if you know how much fixed costs are, you’ll know at least how many products you need to sell to cover your basic costs. This is what’s called the break-even point.

As for variable costs, if you can reduce them, it means the cost per unit of the product will decrease, leading to higher profits. Sometimes, companies invest in new machinery to reduce variable labor costs. Even if fixed costs increase, in the long run it may be worth it.

Combining fixed costs and variable costs is called total cost. This is the figure that tells you how much money is needed to run the business. This information helps you analyze whether your business will make a profit or incur losses when conditions in the market change.

In summary, if you want to manage your business better, you need to understand the difference between fixed cost and variable costs, because it is an essential foundation for all business decisions.
