Fixed Costs vs Variable Costs

Understanding the difference between fixed and variable costs is critical for individuals and businesses alike. Whether you’re managing your household budget or analyzing company expenses, these two types of costs play a significant role in decision-making, cash flow management, and profitability. 

Knowing the difference between the two helps businesses predict cash flow, determine pricing strategies, and manage expenses effectively.

What are Fixed Costs?

Fixed costs are expenses that remain unchanged, regardless of how much a business produces or sells. These costs are predictable, making them easier to plan and budget for. However, since they don’t fluctuate with production levels, they can strain cash flow during slow periods. 

Examples of Fixed Costs:

Rent or Lease Payments

Imagine a bakery renting a commercial space for $2,000 a month. Whether the barkery produces 10 cakes or 10,000 cakes, the rent remains the same. 

Salaries for Permanent Staff

Fixed salaries are paid consistently to full-time employees, regardless of business activity. For instance, the bakery’s manager earns $4,000 every month, whether it’s peak wedding season or a slow winter month. 

Loan Payments

Suppose the bakery took a loan to buy an industrial oven, with monthly repayments of $1,500. These payments remain constant whether the oven is used for 100 hours or sits idle. 

Depreciation

The cost of fixed assets, such as machinery or vehicles, is spread over time as depreciation. For example, the industrial oven might lose $200 in value every month, irrespective of usage. 

What are Variable Costs?

Variable costs, on the other hand, are expenses that fluctuate with production levels or business activity. If production increases, variable costs rise proportionately. Conversely, if production decreases or halts, variable costs drop. 

Example of Variable Costs:

Raw Materials

Let’s say a bakery produces muffins alongside cakes. Each muffin costs $1.50 in raw materials (flour, sugar, butter, etc.). If the bakery produces 500 muffins, the total raw material cost will be: 500 muffins x $1.50 = $750

Utility Costs

Electricity and gas are critical for running ovens and lights. If the bakery increases production, energy usage rises. Conversely, during downtime, utility costs drop significantly. For example, the bakery might pay $300 for electricity in a busy month and $150 during slower months.

Packaging

Packaging costs scale with production. If each box costs $0.50 and the bakery ships 1,000 cupcakes, packaging costs a total of $500. Fewer orders mean fewer expenses.

Commissions

In businesses with commission-based roles, costs increase with sales. For example, if a salesperson earns a 5% commission on cupcake orders, a $1,000 order costs the bakery $50 in commissions. No sales? No commission cost. 

To maintain healthy cash flow, businesses need to strike a balance between fixed and variable costs:

• Plan for Fixed Costs: Ensure consistent cash reserves to cover fixed obligations during slow periods. Consider negotiating fixed costs like rent or salaries to make them more manageable. 
• Monitor Variable Costs: Keep a close eye on expenses that scale with production. Look for ways to optimize processes, reduce waste, and improve cost efficiency. 
• Forecast Cash Flow: Historical data to predict periods of high and low revenue, and adjust spending accordingly. 

How Can Businesses Reduce Variable Expenses?

Reducing variable expenses requires strategic action to optimize operations without compromising quality. Here are some things businesses can do:

• Identify Cost Drivers: Analyze what factors influence variable costs the most—raw materials, energy usage, or labor.
• Optimize Processes: Implement automation to reduce manual work and increase efficiency.
• Negotiate with Vendors: Work with suppliers to secure long-term contracts, bulk discounts, or better payment terms.
• Monitor Usage and Waste: Track resources like energy, raw materials, and supplies to identify areas of waste.
