Simple answer
The debt-to-equity (D/E) ratio compares a company's total debt to its shareholder equity, showing how much of the business is financed by borrowing versus owner capital.
Why this matters
High leverage magnifies both gains and losses. Understanding D/E helps you assess financial risk and sustainability.
Good signs
A lower ratio means less reported debt relative to book equity; it does not establish liquidity or repayment capacity.
Warning signs
A high ratio, or very small or negative equity, needs investigation alongside cash flow, debt maturities and covenants.
Easy mistake to make
Comparing D/E across industries without context, or ignoring off-balance-sheet obligations.
How Wall Street Score helps
WallStreetScore's Financial Strength category incorporates leverage assessment into the overall score.
Use the same definition of debt
Hypothetical interest-bearing debt of $300 million divided by $200 million book equity gives debt-to-equity of 1.5. Total liabilities are not necessarily the same as debt: trade payables and other obligations may be included in one provider's measure and excluded from another.
Check the numerator, balance-sheet date and currency. Distinguish total equity from equity attributable to common shareholders. Ratios from different definitions should not be ranked as if they were interchangeable.
Understand a small or negative denominator
With unchanged $300 million debt, a decline in equity from $200 million to $100 million raises D/E from 1.5 to 3.0. The change does not prove that the company borrowed more. Losses, distributions, repurchases and accounting adjustments can change equity.
At negative $50 million equity, D/E is −6.0. That is not negative borrowing or evidence of low leverage. Review why equity is negative and use other measures; a zero denominator makes the ratio undefined.
Inspect the repayment schedule
D/E does not show when debt must be repaid. Compare cash available for use, recurring operating cash flows, required capital spending and upcoming maturities. Restricted cash and undrawn facilities are not interchangeable with unrestricted cash.
No universal D/E cutoff proves a company is safe. Banks, insurers and industrial businesses have different financing structures. Read the debt notes for variable rates, collateral, covenant restrictions and refinancing needs, then use interest coverage as an additional measure rather than a replacement.
