Financial Leverage
The use of borrowed capital to amplify investment returns, magnifying both gains and losses.
What is Financial Leverage?
Financial leverage refers to the use of debt financing to increase the potential return on equity investment. When a company (or investor) borrows money to fund assets, any returns on those assets that exceed the borrowing cost flow entirely to equity holders — amplifying gains. However, if returns fall below the cost of debt, losses are magnified symmetrically. Financial leverage is measured by ratios such as debt-to-equity and debt-to-assets. High financial leverage increases the risk of financial distress or bankruptcy during downturns. Private equity firms routinely use financial leverage (leveraged buyouts) to amplify equity returns; households use it when taking mortgages; corporations use it to optimize their weighted average cost of capital.
Example
An investor purchases a $1 million rental property with $200,000 equity and an $800,000 mortgage (4:1 financial leverage). If the property value rises 10% to $1.1 million, the $100,000 gain represents a 50% return on the $200,000 equity investment — amplified 5x by leverage. If the property falls 10% to $900,000, the investor loses $100,000 — 50% of their equity. This asymmetry — same percentage move, but 5x the equity impact — defines financial leverage risk.
