Debt-to-Equity Ratio (D/E)
A balance-sheet leverage ratio whose result depends on the debt definition and can be meaningless with zero or negative equity.
Debt-to-equity (D/E) compares a selected debt measure with shareholders' equity. Analysts may use interest-bearing debt or total liabilities, so the numerator must be stated. The ratio describes balance-sheet leverage under accounting values; it does not by itself determine solvency or risk.
Frequently Asked Questions
Should D/E use total debt or total liabilities?
Both conventions exist. Interest-bearing debt focuses on financing obligations, while total liabilities is broader. Results are not comparable unless the numerator, equity class, consolidation scope, and date are consistent.
What if shareholders' equity is zero or negative?
The ratio is undefined at zero equity and often not economically meaningful with negative equity. A negative D/E is not automatically low leverage or a favorable signal.
What is a good debt-to-equity ratio?
There is no universal threshold. Sustainable leverage depends on cash-flow stability, interest coverage, maturities, covenants, collateral, currency, regulation, asset duration, and access to refinancing.
Can D/E be compared across industries?
Only with caution. Banks, insurers, utilities, real estate firms, manufacturers, and software companies have different funding structures and accounting conventions. Peer comparisons should use consistent definitions.
