Cost management in business: How to distinguish between total fixed costs and variable costs

Why Cost Structure Is the Key to Management’s Solution

In a highly competitive business world, knowing where the money flows and why is the golden key to survival. Smart managers must see a 360-degree view of the cost structure to set pricing strategies, make investment decisions, and maintain the company’s financial health. Whether amidst rising or falling markets, understanding fixed costs, variable costs, and their combination will serve as a tool to differentiate pathways in designing stable financial strategies.

Fixed Costs: The Burden That Must Be Carried

Definition: What Are Total Fixed Costs?

Total Fixed Costs are expenses that remain unchanged regardless of production capacity. Businesses must pay these every month, every year, without exception. They are like a mental burden that must be borne, whether sales are high or low.

Key Characteristics of Fixed Costs

Unrelated to Production Volume - Whether producing 100 units or 10,000 units today, these costs stay the same. This differs from variable costs, which fluctuate with the number of goods produced.

Stable and Predictable - Since they do not change, managers can confidently use these figures for long-term budgeting and financial planning.

Impact on Pricing and Profit - Knowing the total fixed costs is crucial for setting a selling price that covers basic costs and leaves a profit margin.

Examples of Total Fixed Costs in Business Operations

• Building and Factory Rent - Paid monthly as per contract, regardless of sales volume.

• Salaries of Permanent Staff - Full-time employees receive the same monthly salary whether the business is doing well or not.

• Insurance and Coverage Costs - Regular payments to protect assets and company contracts.

• Depreciation of Machinery and Equipment - Losses from usage over time, even if not actively used.

• Loan Interest Payments - If borrowed from banks or financial institutions, interest must be paid according to the plan.

Variable Costs: The Fluctuating Numbers

Definition: What Are Variable Costs?

Variable Costs are expenses that fluctuate depending on production levels. The more you produce, the higher the costs; the less you produce, the lower the costs. They are directly proportional to the scale of production and sales.

Special Characteristics of Variable Costs

Change with Production or Sales Levels - If sales increase by 50% this year, variable costs may also increase proportionally.

Provide Flexibility in Cost Management - Since they change with production, businesses can reduce these costs when sales are low.

Affect Profit per Unit - The more units produced, the lower the cost per unit (because higher production helps reduce per-unit costs), known as economies of scale.

Examples of Variable Costs in Production

• Raw Materials and Supplies - The more products made, the more raw materials and supplies are needed.

• Direct Labor Wages - Workers on the production line spend time as needed; more products require more labor hours.

• Energy and Resources for Production - Increased machinery use consumes more electricity, water, and other resources.

• Packaging and Shipping Costs - More products require more packaging and transportation expenses.

• Commissions and Incentives for Sales Teams - Higher sales lead to higher commissions and incentives.

How to Decide Between Investing in Total Fixed Costs or Variable Costs

Many companies face decisions on whether to make a large upfront investment (which increases total fixed costs but reduces variable costs) or to start small and expand gradually (by increasing variable costs while keeping fixed costs low).

For example, a company might decide whether to purchase expensive robotic machinery. If they buy it, depreciation and maintenance costs will be high (high total fixed costs), but labor costs will decrease (lower variable costs). This scenario suits businesses expecting continuous sales growth.

Conversely, if labor costs are already high, investing in automation might be more cost-effective.

Cost Total Analysis for Success

Combining Fixed and Variable Costs

Total Cost = Fixed Costs + Variable Costs

This simple formula is fundamental in business financial analysis because it helps determine the sales volume needed to break even, known as the (Break Even Point).

Practical Applications in Decision-Making

Pricing - Knowing total costs helps set appropriate prices to avoid losses or excessive margins.

Production Planning - If next month’s sales capacity is known, variable costs can be estimated accordingly.

Investment Evaluation - When considering new investments, compare how costs will shift.

Cost Control and Risk Identification - If fixed costs are very high, the business must sell more to cover expenses.

Summary and Practical Recommendations

Understanding the difference between Total Fixed Costs and Variable Costs is not just an accounting lesson but a vital skill for managers to steer their business through competition.

Remember:

• Total Fixed Costs provide stability but can be burdensome — they must be paid regardless of revenue.
• Variable Costs offer flexibility but increase with sales volume.
• Combining both gives a complete picture of the true cost structure.

A well-structured cost base enables a business to have sustainable growth, strong competitiveness, and a secure future. Now you know what total fixed costs and variable costs are. Next, try analyzing your own business using these concepts.
