Debt-to-Equity Ratio Calculator (D/E)

Formula

How this is calculated

The debt-to-equity ratio divides all interest-bearing liabilities by the book value of shareholders' equity. A D/E of 1.0 means debt equals equity; a D/E of 2.0 means the company has borrowed twice its equity base. Higher D/E signals greater financial leverage — amplifying returns on equity when the company earns more than the cost of debt, but magnifying losses and raising distress risk when earnings fall or refinancing tightens.

Financial analysts distinguish two approaches: using total liabilities (current and non-current, including trade payables and deferred taxes) gives 'accounting leverage'; using only interest-bearing financial debt (loans, bonds, notes) gives 'financial leverage'. The latter is more useful for capital-structure comparisons between companies and is the approach most often implied when analysts discuss the D/E ratio.

Industry context matters enormously. Technology companies often run D/E below 0.5; industrials 0.5–1.5; utilities and telecoms 1–3; and banks typically 10–20 because deposits are treated as liabilities by accounting convention. Negative equity — from retained losses or aggressive buybacks — makes D/E negative or undefined. The calculator requires non-zero equity to prevent division by zero.
