Return on Equity
To demonstrate financial leverage, a great financial metric to use is return on equity. If a company has net income of $100,000 and equity of $10,000, its current return on equity is $100,000 / $10,000, or 10. Assume that the company needs $10,000 in new capital. It could issue stock or personally invest the capital as equity.
Using the same figures above, its return on equity is $100,000 / $20,000, or 5. This means less revenue is earned for every dollar of equity. Alternatively, the company could borrow money.
By incurring debt, equity remains unchanged, and its return on equity remains 10. However, the company is now in a riskier financial position because it has a legal obligation to pay back the loan. It must now use cash flow from operations to pay back the loan.
However, whatever profits that are earned are extended to fewer owners, meaning higher income for each owner.
