Leverage: Operating Leverage, Financial Leverage and Combined Leverage

Leverage refers to the use of borrowed funds or fixed-cost inputs by a firm to magnify the potential return to equity shareholders. In financial management, leverage measures the relationship between a firm’s fixed costs (interest on debt, operating fixed costs) and its earnings. When a firm employs assets or funds that have fixed costs, a small change in sales can produce a proportionally larger change in earnings. This “multiplier effect” is the essence of leverage. However, leverage is a double-edged sword—it amplifies profits when sales increase but also magnifies losses when sales decline. The three main types are Operating Leverage (fixed operating costs), Financial Leverage (fixed financing costs), and Combined Leverage (both). Understanding leverage helps managers choose optimal capital structure, assess business risk, and maximize shareholder wealth while avoiding excessive risk.

Objectives of Leverage:

1. Increase in Profitability

The main objective of leverage is to increase the profitability of a business. By using borrowed funds or fixed cost sources, a company can earn higher returns on equity. When the return on investment is greater than the cost of borrowing, leverage helps in increasing profits. It allows the company to expand operations without using too much own capital. However, it must be used carefully to avoid losses. Thus, leverage helps in improving overall earnings and financial performance.

2. Wealth Maximization

Leverage aims at maximizing shareholders’ wealth. By increasing returns on equity, it enhances the value of shares in the market. Proper use of financial leverage leads to higher earnings per share. This attracts investors and increases the market value of the company. It ensures better returns to shareholders. Therefore, wealth maximization is an important objective of leverage in financial management.

3. Efficient Use of Capital

Leverage helps in making efficient use of available capital. Instead of relying only on owned funds, the company uses borrowed funds to finance its activities. This allows better utilization of resources and increases overall productivity. It helps in maintaining an optimal capital structure. Thus, leverage ensures that funds are used in the most effective manner.

4. Expansion of Business

Leverage supports business expansion by providing additional funds. Companies can undertake new projects, increase production, and enter new markets using borrowed capital. It reduces the need for raising equity, which may dilute ownership. This helps in faster growth and development. Therefore, leverage plays a key role in business expansion.

5. Tax Benefit

Interest on borrowed funds is treated as a business expense and is deducted from taxable income. This reduces the overall tax liability of the company. Leverage helps in saving taxes and increasing net profit. This benefit makes debt financing more attractive. Hence, tax advantage is one of the important objectives of using leverage.

Operating Leverage

Operating leverage measures the sensitivity of a firm’s earnings before interest and taxes (EBIT) to changes in sales revenue. It arises from the presence of fixed operating costs (rent, depreciation, salaries, insurance) in the cost structure. When a firm has high fixed costs relative to variable costs, a small percentage change in sales results in a larger percentage change in EBIT. High operating leverage amplifies profits during good times but magnifies losses during downturns. It is determined by the firm’s technology and cost structure, not by financing decisions.

Formula: The Degree of Operating Leverage (DOL) is calculated as:

DOL = Contribution / EBIT

Where Contribution = Sales – Variable Costs, and EBIT = Contribution – Fixed Operating Costs.

Alternatively: DOL = (% Change in EBIT) / (% Change in Sales)

A DOL of 3 means a 1% increase in sales will produce a 3% increase in EBIT.

Significance of Operating Leverage:

1. Helps in Profit Planning

Operating leverage helps management in planning profits effectively. It shows how changes in sales affect operating profit due to fixed costs. A higher operating leverage means a small increase in sales can lead to a large increase in profit. This helps managers set sales targets and pricing strategies. It also supports decision making related to cost structure. Therefore, operating leverage is important for proper profit planning.

2. Measures Business Risk

Operating leverage is useful in measuring business risk. A company with high fixed costs has high operating leverage, which increases risk. If sales decrease, profits may fall sharply. It helps management understand the level of risk involved in operations. By analyzing operating leverage, companies can control costs and reduce risk. Thus, it is an important tool for risk assessment.

3. Assists in Cost Control

Operating leverage highlights the importance of fixed and variable costs in a business. It helps management control costs by maintaining a proper balance between them. Companies can reduce fixed costs or increase efficiency to improve profitability. This leads to better cost management. Therefore, operating leverage plays a key role in controlling and managing business costs.

4. Improves Decision Making

Operating leverage supports better decision making by showing the impact of cost structure on profits. Management can decide whether to invest in fixed assets or reduce variable costs. It helps in choosing the best production method and pricing strategy. This improves overall business performance. Hence, it is useful in making effective managerial decisions.

5. Indicates Break Even Point

Operating leverage helps in understanding the break even point of a business. High operating leverage means a higher break even point, as fixed costs are more. It shows how much sales are required to cover costs. This helps in planning production and sales levels. Therefore, it is useful in analyzing break even and ensuring profitability.

6. Supports Business Expansion Decisions

Operating leverage helps in making decisions related to business expansion. It shows whether increasing fixed costs will lead to higher profits in the future. Companies can analyze the effect of expansion on earnings before making decisions. It ensures that expansion plans are financially viable. Thus, operating leverage is important for growth and expansion decisions.

Financial Leverage

Financial leverage refers to the use of fixed-cost sources of finance (debt, preference shares) in a firm’s capital structure to magnify the returns to equity shareholders. It arises when a firm borrows funds at a fixed rate of interest and invests them in assets that earn a higher rate of return. The difference between the return on assets and the cost of debt accrues to equity shareholders. Financial leverage amplifies earnings per share (EPS) when operating profits are rising but can drastically reduce or wipe out EPS during downturns. It directly affects the financial risk of the firm.

Formula: The Degree of Financial Leverage (DFL) is calculated as:

DFL = EBIT / EBT

Where EBIT = Earnings Before Interest and Taxes, and EBT = Earnings Before Tax (EBIT – Interest).

Alternatively: DFL = (% Change in EPS) / (% Change in EBIT)

A DFL of 2 means a 1% change in EBIT will produce a 2% change in EPS.

Significance of Financial Leverage:

1. Improves Return on Equity

Financial leverage helps in increasing return on equity by using borrowed funds. When the return on investment is higher than the cost of debt, shareholders earn more profit. This increases earnings per share and overall profitability. It allows the company to generate higher returns without increasing equity capital. Therefore, financial leverage is important for improving shareholders’ returns.

2. Helps in Capital Structure Planning

Financial leverage plays an important role in designing the capital structure of a company. It helps in deciding the right mix of debt and equity. Proper use of debt reduces overall cost of capital and increases firm value. It ensures efficient financing of business activities. Thus, financial leverage is significant in capital structure decisions.

3. Provides Tax Benefits

Interest on borrowed funds is treated as an expense and is deducted from taxable income. This reduces the tax burden of the company. Financial leverage helps in saving taxes and increasing net profit. It makes debt financing more attractive compared to equity. Hence, tax benefit is a major significance of financial leverage.

4. Assists in Business Expansion

Financial leverage provides additional funds for expansion and growth. Companies can invest in new projects, increase production, and enter new markets using borrowed capital. It reduces the need to issue new shares, which may dilute ownership. Therefore, financial leverage supports business expansion and development.

5. Maintains Control

Financial leverage helps in maintaining control of the company. By using debt instead of equity, the company avoids issuing new shares. This prevents dilution of ownership and voting rights. Existing shareholders can retain control over management decisions. Thus, financial leverage is useful in preserving ownership control.

6. Increases Financial Risk Awareness

Financial leverage helps in understanding financial risk. Higher debt increases fixed obligations like interest payments, which raises financial risk. It makes management more careful in decision making. By analyzing leverage, companies can maintain a balance between risk and return. Therefore, it is significant for managing financial risk.

Combined Leverage:

Combined leverage (also known as total leverage) measures the overall sensitivity of a firm’s earnings per share (EPS) to changes in sales revenue. It is the product of operating leverage and financial leverage. Operating leverage magnifies the effect of sales changes on EBIT (earnings before interest and taxes), while financial leverage further magnifies the effect of EBIT changes on EPS. Combined leverage captures the total risk of the firm—both business risk (from operating leverage) and financial risk (from financial leverage). High combined leverage means a small change in sales produces a very large change in EPS, offering high potential returns but also high downside risk.

Formula: The Degree of Combined Leverage (DCL) is calculated as:

DCL = DOL × DFL

Alternatively: DCL = Contribution / EBT

Where Contribution = Sales – Variable Costs, and EBT = Earnings Before Tax (EBIT – Interest).

Also: DCL = (% Change in EPS) / (% Change in Sales)

Significance of  Combined Leverage:

1. Measures Total Risk

Combined leverage measures the overall risk of a business by combining operating and financial leverage. It shows the effect of both fixed operating costs and fixed financial costs on earnings. A high combined leverage indicates higher total risk, as small changes in sales can cause large changes in profit. This helps management understand the total risk position of the company. Therefore, it is important for evaluating business risk.

2. Helps in Profit Planning

Combined leverage helps in planning profits by showing the relationship between sales and earnings per share. It indicates how changes in sales will affect overall profitability. Management can set realistic sales targets to achieve desired profit levels. It also helps in forecasting future earnings. Thus, combined leverage is useful for effective profit planning.

3. Assists in Decision Making

Combined leverage supports managerial decision making by providing a complete view of cost structure. It helps in deciding the level of fixed and variable costs as well as debt and equity mix. Management can choose strategies that maximize returns and minimize risk. Therefore, it improves the quality of business decisions.

4. Evaluates Impact of Sales Changes

Combined leverage shows how sensitive profits are to changes in sales. Even a small increase or decrease in sales can have a large impact on earnings. This helps companies prepare for fluctuations in demand. It is useful in analyzing best case and worst case situations. Hence, it helps in understanding the impact of sales variations.

5. Aids in Financial Planning

Combined leverage is important for overall financial planning. It helps in balancing operating and financial leverage to achieve stability. Companies can plan their financing and cost structure more effectively. It ensures proper coordination between operational and financial decisions. Therefore, it plays a key role in financial planning.

6. Supports Growth Decisions

Combined leverage helps in making decisions related to growth and expansion. It shows whether increasing fixed costs and debt will improve profitability. Management can analyze the effect of expansion on risk and return. This ensures that growth decisions are financially sound. Thus, combined leverage supports long term business growth.
