Debt-to-Equity Ratio
A debt-to-equity ratio of 1.0 means a company finances itself with exactly as much borrowed money as owner money: total debt divided by shareholders' equity, both straight off the balance sheet. At 0.3 the balance sheet is conservative; at 2.5 the lenders own most of the risk.
The ratio is only meaningful against the sector. Utilities and telecoms run at 1.5-2.0x comfortably because regulated cash flows service the debt; a software company at the same level would be an outlier. Comparing a bank's D/E to a retailer's tells you nothing — banks are leverage machines by design.
Two distortions to check before trusting the number. Buybacks shrink the equity denominator, so a shareholder-friendly company can look more levered every year without borrowing a dollar. And when buybacks push equity negative, the ratio breaks entirely — several large consumer brands report negative equity while carrying investment-grade credit ratings. Debt-to-EBITDA is the cross-check that keeps working.
A manufacturer carries $600M of total debt against $400M of shareholders' equity: D/E = 600 / 400 = 1.5. Its competitor has $600M of debt on $1.2B of equity: 600 / 1,200 = 0.5. Same debt load, very different cushion if earnings roll over.
