Understanding your business costs is important for success, and one important aspect is this concept. This ratio shows how much of your sales are spent on variable expenses, which change with your production or sales levels. 

By keeping an eye on this ratio, you can make better decisions about pricing, budgeting, and improving your profit margins. In this blog, we'll simplify the concept of variable expenses and this, so you can easily apply this knowledge to your business. Let's get started!

Definition and Explanation of Variable Expenses

Variable expenses are business costs that fluctuate directly with the level of production or sales activity. In simpler terms, as a company produces or sells more, these expenses increase proportionally. Examples of variable expenses include:

  • Direct Materials: The raw materials used to manufacture a product. For instance, a bakery's flour, sugar, and eggs.

  • Direct Labor: The wages paid to workers directly involved in production. This could be assembly line workers or bakers in our bakery example.

  • Sales Commissions: Payments to salespeople based on their sales volume.

  • Variable Overhead Costs: Expenses that change with production levels, such as utilities used in manufacturing or shipping costs per unit sold.

Contrast Between Variable and Fixed Expenses

The key difference between variable and fixed expenses lies in their response to changes in production or sales volume. Fixed expenses, unlike variable expenses, remain constant regardless of activity levels. Examples of fixed expenses include:

  • Rent: The monthly lease payment for a building or office space.

  • Salaries: Fixed salaries paid to administrative staff, regardless of production levels.

  • Depreciation: The non-cash expense of spreading the cost of an asset over its useful life.

Significance of Distinct Expense Categories: Fixed vs. Variable

Understanding the distinction between fixed and variable expenses is crucial for businesses. It helps them:

  • Cost Control: Identify areas for potential cost savings. By analyzing variable expenses, companies can find ways to reduce material waste, negotiate better prices with suppliers, or optimize production processes.

  • Profit Planning: Predict future profits by estimating how variable expenses will change with different sales volumes.

  • Pricing Strategies: Set optimal product prices by considering how variable costs impact the contribution margin (the amount available to cover fixed costs and generate profit).

Understanding The Concept In Detail

understanding variable expense ratio

It is a financial metric that expresses a company's variable expenses as a percentage of its net sales. It's calculated by dividing the total variable expenses by the total net sales and multiplying by 100.

Formula: Variable Expense Ratio = (Variable Expenses / Net Sales) x 100

Significance in Financial Analysis

It is a valuable tool for financial analysts because it helps them assess:

  • Profitability: A lower amount indicates a higher contribution margin, leading to potentially greater profitability.

  • Efficiency: A high ratio suggests the company might be spending too much on variable costs per unit of production.

  • Industry Comparison: Compare a company's variable expense ratio to industry benchmarks to understand its relative cost efficiency.

The Role of VER in Cost-Volume-Profit (CVP) Analysis and Break-Even Point Analysis

It plays a key role in cost-volume-profit (CVP) analysis, which helps businesses understand the relationship between costs, sales volume, and profit. It's also crucial for break-even point analysis, which identifies the sales volume required to cover all costs (both fixed and variable) without generating a profit or loss.

Determining the Impact of Variable Expenses on Business Pricing Strategies and Profit Margins

Variable expenses significantly impact a company's pricing strategies and profit margins. Here's how:

  • Pricing: Businesses consider variable costs when setting product prices. A higher variable expense ratio may necessitate higher prices to maintain sufficient contribution margin.

  • Profit Margins: Variable expenses directly affect profit margins. By minimizing variable costs, companies can increase their profit margin on each unit sold.

Calculation

This part will provide an overview of the calculation method for it, including the formula and its interpretation. It will also discuss an alternative method for calculating the ratio using the concept of contribution margin.

Overview of Calculation Method

it is a straightforward metric that expresses a company's variable expenses as a percentage of its net sales. In simpler terms, it reveals how much of each sales dollar is consumed by variable costs.

Explanation of it Formula

The formula for calculating it is:

Variable Expense Ratio = (Variable Expenses / Net Sales) x 100

  • Variable Expenses: The total cost of expenses that fluctuate with production or sales volume.

  • Net Sales: The total revenue from sales after accounting for returns, allowances, and discounts.

Example: If a company incurs $10,000 in variable expenses and generates $50,000 in net sales, its variable expense ratio would be:

(Variable Expense Ratio = ($10,000 / $50,000) x 100) = 20%

This indicates that for every dollar of sales, 20 cents goes towards variable costs.

Alternative Method and Interpretation: 1 – Contribution Margin

There's an alternative way to calculate it using the concept of contribution margin:

Variable Expense Ratio = 1 - (Contribution Margin Ratio)

  • Contribution Margin Ratio: The percentage of sales revenue remaining after covering variable expenses. It represents the amount available to cover fixed costs and generate profit.

Important Considerations

When calculating it, it's crucial to consider the following:

  • Consistency in Time Period: Ensure both variable expenses and net sales figures are from the same time period (e.g., month, quarter, year).

  • Basis of Calculation: Clearly define whether variable expenses are based on cash payments, accruals, or another method.

  • Sales Revenue Treatment: Determine if net sales or gross sales are used in the calculation. Most commonly, net sales (after deductions) are preferred.

Challenges in Accurately Measuring Variable Expenses

Accurately measuring variable expenses can be challenging due to:

  • Mixed Costs: Certain expenses may have both fixed and variable elements (e.g., utilities). Isolating the variable portion requires careful analysis.

  • Estimation: Variable costs may be estimated based on historical data or production forecasts, introducing potential inaccuracies.

The Right Formula

This part will present the mathematical formula for calculating it and introduce the contribution margin ratio as a related metric.

The Mathematical Formula 

As discussed earlier, the mathematical formula for calculating it is:

Variable Expense Ratio = (Variable Expenses / Net Sales) x 100

This formula provides a clear and concise way to express the relationship between variable costs and sales revenue.

Introduction of a Related Metric: Contribution Margin and its Significance

The contribution margin ratio is a closely related metric to it. It's calculated as:

Contribution Margin Ratio = (Sales Revenue - Variable Expenses) / Sales Revenue

The contribution margin ratio signifies the portion of sales revenue remaining after covering variable expenses. It essentially highlights the company's ability to generate profit after accounting for variable costs.

Examples and Calculation

This part will explain how to calculate it using a step-by-step approach and provide an example calculation. It will also discuss the impact of it on profitability and verify the calculation using the contribution margin ratio.

Explanation of How to Calculate (Step-by-Step)

Calculating it is a straightforward process. Here's a step-by-step approach:

  1. Gather Data: Identify the company's total variable expenses and net sales for a specific period (month, quarter, year). Ensure both figures are from the same time frame.

  2. Apply the Formula: Use the formula: Variable Expense Ratio = (Variable Expenses / Net Sales) x 100.

  3. Calculate and Interpret: Plug in the gathered data and perform the calculation. The resulting percentage represents it. A lower ratio indicates a smaller portion of sales revenue consumed by variable costs, potentially leading to higher profitability.

Example Calculation: A Company Scenario

Let's consider a company, ABC Inc., with the following figures for the last quarter:

  • Variable Expenses: $25,000
  • Net Sales: $100,000

Following the steps above:

  1. Data: Variable Expenses = $25,000, Net Sales = $100,000 (both from the last quarter).

  2. Formula: Variable Expense Ratio = ($25,000 / $100,000) x 100.

  3. Calculation and Interpretation: it is 25% (25,000 / 100,000 x 100). This means that for every dollar of sales, ABC Inc. incurs 25 cents in variable costs.

Using Standard and Alternative Formulas for Verification

We can verify the calculation using the alternative formula based on contribution margin ratio:

  1. Contribution Margin Ratio = (Sales Revenue - Variable Expenses) / Sales Revenue

  2. Contribution Margin Ratio = ($100,000 - $25,000) / $100,000 = 75%

  3. VER = 1 - Contribution Margin Ratio

  4. VER = 1 - 75% = 25%

Impact on Profitability: High vs. Low VER

A company's VER significantly impacts its profitability. Here's a breakdown:

  • High Variable Expense Ratio (e.g., above 70%): A high ratio suggests a large portion of sales revenue is consumed by variable costs. This can limit contribution margin and potentially lead to lower profitability. Companies with high VER may need to explore cost-reduction strategies or adjust pricing to maintain profit margins.

  • Low VER (e.g., below 30%): A low ratio indicates a smaller portion of sales revenue is spent on variable costs. This allows for a higher contribution margin and potentially greater profitability. However, a very low ratio might suggest underinvestment in variable factors like production or sales efforts.

Determining a Good VER

This depends on factors such as industry, business model, and market conditions. It will also analyze how different business scenarios can affect the desirable ratio.

Dependence on Business Model and Market Conditions

There's no single "good" amount that applies universally. The ideal ratio depends on several factors, including:

  • Industry: Labor-intensive industries like manufacturing might naturally have higher variable expense ratios compared to service industries.

  • Business Model: Companies with low-cost, high-volume production (e.g., retail) may have a different optimal ratio than those with customized, high-margin products.

  • Market Conditions: Fluctuations in raw material prices or labor costs can impact a company's variable expenses and influence the desirable ratio.

Analyzing How Different Business Scenarios Affect the Desirable Ratio?

  • Company A: A high-volume clothing manufacturer might target a lower VER (around 50%) due to economies of scale in production.

  • Company B: A consulting firm offering customized services might target a higher VER (around 70%) as employee salaries (a variable cost) form a significant expense.

Reasons Why Accountants and Financial Analysts Track This Ratio

Accountants and financial analysts track it for several reasons:

  • Cost Management: Monitoring the ratio helps identify areas for potential cost reduction in variable expenses.

  • Profitability Analysis: Understanding it is crucial for assessing a company's profit potential and contribution margin.

  • Industry Comparison: Comparing a company's VER to industry benchmarks provides insights into its relative cost efficiency.
