What Is Operating Leverage?

Operating leverage is a measure of how a company's operating income changes in response to a change in sales revenue. It quantifies the proportion of fixed costs within a company's total cost structure. Companies with high operating leverage have a greater proportion of fixed costs relative to variable costs. This characteristic means that once a certain sales volume is achieved, small increases in revenue can lead to significantly larger increases in profit, as the high fixed costs are already covered. Conversely, a small decline in sales can result in a sharp drop in operating income, making operating leverage a key concept in corporate finance and financial analysis.

History and Origin

The concept of leverage, generally referring to the use of borrowed capital or fixed expenses to amplify returns, has roots in early business and financial analysis. Operating leverage, specifically, gained prominence as analysts began to dissect the components of a company's profitability and associated risks. Early academic discussions in the mid-20th century explored how different cost structures affected a firm's sensitivity to sales fluctuations. Researchers aimed to quantify the relationship between costs, sales, and profits, leading to formal definitions and measures of this operational sensitivity. The idea that fixed production costs behave much like financial leverage in magnifying risk and affecting expected returns has been put forward since at least the early 1970s.⁶ The analytical understanding of operating leverage has evolved, with some academic discussion pointing out the imprecision in definitions and measurement methods in various textbooks and scientific publications, highlighting ongoing efforts to refine the concept.⁴, ⁵

Key Takeaways

• Operating leverage measures the sensitivity of a company's operating income to changes in sales revenue.
• It is driven by the proportion of fixed costs versus variable costs in a firm's cost structure.
• High operating leverage can lead to magnified profits during sales increases but also amplified losses during sales decreases.
• Understanding a firm's operating leverage is crucial for assessing its business risk and potential profitability.
• Industries with significant investments in property, plant, and equipment, or high research and development expenses, often exhibit high operating leverage.

Formula and Calculation

The most common measure of operating leverage is the Degree of Operating Leverage (DOL). The DOL quantifies the percentage change in earnings before interest and taxes (EBIT) for a given percentage change in sales volume.

The formula for the Degree of Operating Leverage (DOL) is:

Alternatively, DOL can be calculated using the contribution margin approach:

Where:

• Sales = Total sales revenue
• Variable Costs = Costs that change in direct proportion to the volume of goods or services produced (e.g., cost of goods sold)
• Fixed Costs = Costs that do not change with the volume of goods or services produced within a relevant range (e.g., rent, depreciation, selling, general, and administrative expenses)
• Contribution Margin = Sales - Variable Costs
• EBIT = Earnings Before Interest and Taxes (Operating Income)

Interpreting the Operating Leverage

A higher Degree of Operating Leverage (DOL) indicates that a company has a larger proportion of fixed costs in its cost structure. This means that for every percentage point increase in sales, EBIT will increase by a greater percentage, potentially leading to substantial profitability gains. Conversely, a high DOL also implies that a small decrease in sales will lead to a proportionally larger decrease in EBIT, exposing the company to greater operating risk.

Companies with low operating leverage have a higher proportion of variable costs. Their EBIT will be less sensitive to changes in sales volume, meaning profits grow more slowly during periods of increasing sales but are also more resilient during downturns. The ideal level of operating leverage depends heavily on industry characteristics, market stability, and the company's ability to consistently generate sales above its break-even point. Investors and analysts evaluate DOL to understand the inherent risk and reward profile of a company's operations.

Hypothetical Example

Consider two hypothetical companies, Alpha Corp and Beta Corp, both in the manufacturing sector, with current annual sales of $1,000,000.

Alpha Corp (High Operating Leverage):

• Sales: $1,000,000
• Variable Costs: $300,000
• Fixed Costs: $500,000
• EBIT = Sales - Variable Costs - Fixed Costs = $1,000,000 - $300,000 - $500,000 = $200,000

DOL for Alpha Corp = ( $1,000,000 - $300,000 ) / $200,000 = $700,000 / $200,000 = 3.5

If Alpha Corp's sales increase by 10% to $1,100,000:

• New Variable Costs: $330,000 (30% of new sales)
• New Fixed Costs: $500,000 (remain constant)
• New EBIT = $1,100,000 - $330,000 - $500,000 = $270,000
• Percentage change in EBIT = (($270,000 - $200,000) / $200,000) * 100% = 35%

A 10% increase in sales led to a 35% increase in EBIT, which is 3.5 times the sales increase, aligning with the calculated DOL of 3.5.

Beta Corp (Low Operating Leverage):

• Sales: $1,000,000
• Variable Costs: $600,000
• Fixed Costs: $150,000
• EBIT = $1,000,000 - $600,000 - $150,000 = $250,000

DOL for Beta Corp = ( $1,000,000 - $600,000 ) / $250,000 = $400,000 / $250,000 = 1.6

If Beta Corp's sales increase by 10% to $1,100,000:

• New Variable Costs: $660,000 (60% of new sales)
• New Fixed Costs: $150,000 (remain constant)
• New EBIT = $1,100,000 - $660,000 - $150,000 = $290,000
• Percentage change in EBIT = (($290,000 - $250,000) / $250,000) * 100% = 16%

A 10% increase in sales led to a 16% increase in EBIT, which is 1.6 times the sales increase, consistent with the DOL of 1.6. This example illustrates how operating leverage amplifies changes in operating income based on the proportion of fixed costs.

Practical Applications

Operating leverage is a vital metric used across various facets of financial analysis and strategic planning. In investing, analysts assess a company's operating leverage to understand its earnings volatility and potential for magnified returns or losses in different economic cycles. Companies with high operating leverage, such as airlines or heavy manufacturers, can see their return on assets swing widely with changes in demand, as significant capital outlays for aircraft or machinery represent large fixed costs.

For internal management, understanding operating leverage informs decisions related to production methods, technology adoption, and pricing strategies. Businesses might choose to automate processes (increasing fixed costs) to gain higher operating leverage, aiming for greater profitability at higher volumes. Conversely, they might opt for more flexible, variable-cost-intensive models to reduce their exposure to sales downturns. Academic research also explores how operating leverage influences a firm's capital structure and profitability, noting a potential negative relationship between operating and financial leverage due to a substitution effect.², ³ Furthermore, the Federal Reserve has published insights on how fixed cost dynamics impact investment decisions, implicitly connecting to the strategic implications of operating leverage for businesses.

Limitations and Criticisms

While operating leverage is a powerful analytical tool, it has limitations. One criticism is that the distinction between fixed and variable costs can be blurry in the real world, as some costs are "semi-variable" or "step-fixed," changing only after certain thresholds. This makes precise calculation and interpretation challenging. Furthermore, the Degree of Operating Leverage (DOL) is calculated at a specific sales level and can change significantly as sales volumes move away from the break-even point.

Another point of contention in academic circles is the relationship between operating leverage and systematic risk. Some research suggests a direct link, where higher operating leverage implies greater sensitivity to market-wide economic fluctuations. However, other studies have found that operating leverage may not have a significant effect on systematic risk for all listed companies, indicating the complexity and context-dependency of its impact.¹ It's important for financial professionals to conduct a comprehensive sensitivity analysis and consider qualitative factors alongside quantitative measures when evaluating a firm's operating leverage. Over-reliance on operating leverage figures without considering market volatility or competitive dynamics can lead to misjudgments regarding a company's long-term solvency or potential for shareholder value creation.

Operating Leverage vs. Financial Leverage

Operating leverage and financial leverage are distinct yet related concepts in finance, both dealing with the use of fixed costs to amplify returns, but from different parts of a company's operations.

Operating leverage focuses on the impact of a company's operational cost structure—specifically, the proportion of fixed operating costs versus variable operating costs—on its earnings before interest and taxes (EBIT). A high degree of operating leverage means that a small change in sales leads to a larger percentage change in operating income.

Financial leverage, on the other hand, deals with the use of borrowed capital (debt) to finance assets. It measures the extent to which a company's assets are financed by debt, and how changes in EBIT affect earnings per share (EPS). Companies with high financial leverage have significant interest expenses (a fixed financial cost) that can amplify the impact of changes in EBIT on net income and EPS.

The confusion between the two often arises because both introduce fixed costs (operational for operating leverage, interest for financial leverage) that amplify returns and risks. However, operating leverage relates to a company's core business operations and its ability to generate profit from sales, while financial leverage relates to its financing decisions and the distribution of that profit to shareholders after debt obligations. It's possible for a company to have high operating leverage but low financial leverage, or vice versa, influencing its overall risk profile.

FAQs

What does high operating leverage mean for a business?

High operating leverage means a business has a large proportion of fixed costs relative to its variable costs. This amplifies the impact of sales changes on operating income; a small increase in sales can lead to a much larger increase in profits, but a small decrease in sales can result in a proportionally larger decline in profits. It implies higher business risk.

Is operating leverage good or bad?

Operating leverage is neither inherently good nor bad; its desirability depends on the context. In a growing market with stable or increasing revenue, high operating leverage can lead to substantial profitability. However, in volatile markets or during economic downturns, high operating leverage can expose a company to significant losses due to its inability to quickly reduce fixed expenses.

How do companies manage their operating leverage?

Companies manage operating leverage by adjusting their cost structure. This can involve decisions to automate production (increasing fixed costs) versus using more labor (increasing variable costs), or outsourcing certain functions. The goal is often to strike a balance between maximizing profit potential during good times and maintaining flexibility to minimize losses during challenging periods.

Does operating leverage affect a company's stock price?

Yes, operating leverage can affect a company's stock price indirectly. Investors consider operating leverage when assessing a company's risk profile and earnings volatility. Companies with high operating leverage might be seen as riskier but with higher upside potential, which can influence investor sentiment and, consequently, the stock's valuation. However, many other factors also influence stock prices.
