What Is Leverage?

Leverage in finance refers to the strategic use of borrowed capital, or debt, to amplify the potential returns on an investment. It is a core concept within corporate finance and plays a significant role in how companies and investors finance their assets and operations. By employing leverage, an entity aims to generate greater earnings from an investment than the cost of borrowing the funds. This technique can magnify both gains and losses, making it a powerful but potentially risky financial tool. Companies use leverage to fund expansions, acquisitions, or simply to increase their overall asset base without issuing additional equity.

History and Origin

The fundamental concept of using borrowed capital to enhance potential returns has roots dating back to ancient civilizations, where merchants would borrow funds to finance trade expeditions with the expectation of generating greater value upon their return. The emergence of modern banking institutions in the 17th century further facilitated the widespread use of debt financing for various ventures⁴. The term "leverage" itself derives from the physics principle of a lever, which amplifies a small input force into a greater output force, metaphorically representing how borrowed money can amplify financial outcomes. Over centuries, the application of leverage evolved from rudimentary forms of debt to the sophisticated financial instruments seen today.

Key Takeaways

• Leverage involves using borrowed funds to increase the potential return on an investment or project.
• It can amplify both positive gains and negative losses.
• Key measures of leverage include debt-to-equity and debt-to-assets ratios.
• While offering the potential for higher returns, excessive leverage significantly increases risk and the likelihood of bankruptcy.
• Regulators impose limits on leverage, particularly in the banking sector, to maintain financial stability.

Formula and Calculation

Leverage can be measured in several ways using financial ratios. Two common ratios are the Debt-to-Equity Ratio and the Debt-to-Assets Ratio.

Debt-to-Equity Ratio (D/E): This ratio indicates the proportion of debt and equity a company uses to finance its assets.

• Total Debt: Includes both short-term and long-term liabilities on the balance sheet.
• Shareholders' Equity: The capital contributed by owners plus retained earnings.

Debt-to-Assets Ratio: This ratio shows the proportion of a company's assets that are financed by debt.

• Total Assets: The sum of all economic resources controlled by the company.

Interpreting the Leverage

Interpreting a company's leverage involves understanding its capital structure and risk profile. A higher leverage ratio generally indicates a greater reliance on debt financing. While this can boost return on equity during prosperous times, it also exposes the company to higher financial risk, as it must meet its fixed interest expense obligations regardless of its profitability.

For example, a company with a high debt-to-equity ratio might achieve higher returns for shareholders if the return on its assets exceeds the cost of its debt. Conversely, if returns fall below the cost of debt, the magnified effect of leverage will lead to a disproportionately larger decline in shareholder returns, and could threaten the company's solvency. The ideal level of leverage varies significantly by industry, business model, and economic conditions. Companies in stable industries with predictable cash flows may be able to sustain higher levels of leverage than those in volatile sectors.

Hypothetical Example

Consider Company A and Company B, both operating with $1,000,000 in total assets.

• Company A (Low Leverage): Has $200,000 in debt and $800,000 in equity.
  • Debt-to-Equity Ratio = $200,000 / $800,000 = 0.25
  • Debt-to-Assets Ratio = $200,000 / $1,000,000 = 0.20
• Company B (High Leverage): Has $700,000 in debt and $300,000 in equity.
  • Debt-to-Equity Ratio = $700,000 / $300,000 = 2.33
  • Debt-to-Assets Ratio = $700,000 / $1,000,000 = 0.70

Assume both companies generate $150,000 in earnings before interest and taxes (EBIT) and face a 10% interest rate on their debt.

• Company A:
  • Interest Expense: $200,000 * 10% = $20,000
  • Earnings Before Tax: $150,000 - $20,000 = $130,000
• Company B:
  • Interest Expense: $700,000 * 10% = $70,000
  • Earnings Before Tax: $150,000 - $70,000 = $80,000

In a good year, Company B, with its higher leverage, will likely show a higher return on its smaller equity base, demonstrating the magnifying effect of leverage on profitability. However, if EBIT drops, Company B's earnings would be much more severely impacted due to its larger fixed interest obligations.

Practical Applications

Leverage is widely applied across various aspects of finance and investing:

• Corporate Finance: Companies use leverage to finance operations and growth, balancing the tax benefits of debt with the risks of financial distress.
• Real Estate: Investors often use mortgages to leverage their real estate purchases, allowing them to control a larger property with a smaller initial investment.
• Private Equity: Private equity firms frequently employ high levels of leverage in their acquisitions to enhance returns for their investors.
• Derivatives and Margin Trading: In securities markets, investors use options, futures, and margin accounts to apply leverage, multiplying their buying power or exposure to assets.
• Financial Regulation: Regulators, such as the Bank for International Settlements (BIS), implement specific rules, like the Basel III leverage ratio, to limit excessive leverage in the banking sector and safeguard global financial stability³. These regulations aim to prevent the build-up of systemic risk that can arise from highly leveraged financial institutions.

Limitations and Criticisms

While offering significant opportunities, leverage comes with substantial drawbacks and criticisms:

• Amplified Losses: Just as leverage can magnify gains, it equally magnifies losses. A small decline in the value of a leveraged asset can lead to a much larger percentage loss on the equity invested, potentially exceeding the initial investment.
• Increased Risk of Default: High levels of leverage increase a company's fixed financial obligations (interest payments). If revenues decline or costs increase, the company may struggle to meet these payments, leading to financial distress or bankruptcy.
• Market Volatility: Highly leveraged entities are more susceptible to market downturns. During periods of economic contraction, the value of assets may fall, triggering margin calls or forcing liquidations at unfavorable prices.
• Systemic Risk: Excessive leverage within the financial system can contribute to systemic crises. The 2007-2009 financial crisis, for instance, was significantly exacerbated by the build-up of excessive leverage in the banking sector, leading to widespread defaults and a severe economic contraction². Critics argue that the interconnectedness of highly leveraged institutions can create a cascade effect during times of stress.
• Impact on Performance: Academic research suggests a nuanced relationship between leverage and firm performance. While moderate leverage can enhance firm value, excessive debt may lead to diminished profitability and undermine long-term sustainability, particularly in volatile markets¹.

Leverage vs. Margin

While often used interchangeably, leverage and margin have distinct meanings, particularly in trading.

In essence, margin is a specific mechanism by which investors can obtain leverage in the securities markets. When an investor buys on margin, they are using leverage.

FAQs

What are the main types of leverage?

The two main types are financial leverage and operating leverage. Financial leverage involves using borrowed funds (debt) to finance assets, while operating leverage refers to a company's proportion of fixed costs to variable costs. A high degree of operating leverage means a large portion of costs are fixed, amplifying changes in sales revenue into larger changes in operating income.

Is leverage always risky?

Leverage inherently involves risk because it amplifies both gains and losses. While it can lead to higher returns on equity, it also increases fixed financial obligations and the potential for magnified losses if an investment performs poorly. The level of risk depends on various factors, including the amount of debt used, the stability of cash flows, and market conditions.

How do companies decide how much leverage to use?

Companies aim to find an optimal capital structure that balances the benefits of debt (like tax deductibility of interest expense) with the costs and risks of financial distress. This decision considers factors such as industry norms, business stability, growth opportunities, and access to different forms of financing. Financial managers often use various financial ratios and financial modeling to assess the impact of different leverage levels.

Can individuals use leverage?

Yes, individuals commonly use leverage, often without realizing it. Examples include taking out a mortgage to buy a home, using a credit card for purchases, or investing in the stock market using a margin account. Each of these involves borrowing money to acquire an asset or make a purchase, with the expectation that the benefits outweigh the borrowing costs.
