D/E ratio — the leverage measure that runs every credit decision

10 Things to Know About D/E

Frequently asked questions

• Should I include short-term debt?+

  Yes — include all interest-bearing debt regardless of maturity. Long-term debt + current portion of long-term debt + commercial paper + short-term bank loans + finance leases. Exclude operating leases (which under ASC 842 / IFRS 16 now appear on the balance sheet but are operating obligations not financing), trade payables, and accrued expenses. The economic question D/E answers is "how much fixed-cost financing commits the firm" — all interest-bearing debt counts.

• What\'s "net" D/E?+

  Net D/E = (Total Debt − Cash) ÷ Equity. Subtracting cash makes sense because cash sitting on the balance sheet can immediately pay down debt — it effectively offsets debt at the same risk-free rate. For Apple (~$60B net cash), gross D/E ≈ 1.5 but net D/E ≈ 0.1 — totally different leverage story. For firms with material cash piles (Apple, Microsoft, Berkshire, large tech), net D/E is the meaningful number. For firms with modest cash, the gross-net distinction barely matters. Always specify which version you\'re using.

• Why do banks have such high D/E?+

  Banks are inherently leveraged businesses — they take deposits (liabilities/debt) and make loans (assets). A bank with $10B in deposits + $1B in equity has D/E of 10. Basel III regulations set minimum capital ratios that effectively constrain bank D/E to roughly 10-15× (Tier 1 capital ratio typically 8-12%). For banks, D/E doesn\'t convey financial distress signals the way it does for non-financials — the leverage is structural, not strategic. Bank credit analysis uses different metrics: NIM (net interest margin), CET1 ratio, NPL ratio, liquidity coverage ratio.

• What if equity is negative?+

  Negative book equity means accumulated losses exceed paid-in capital — D/E becomes mathematically meaningless (negative or undefined). Common in distressed firms, recent IPOs after large losses, or firms with large share buybacks reducing equity below paid-in capital. For these, use (a) market D/E if market equity is still positive (the firm has option value but accounting equity is gone), (b) Total Debt / Total Assets as an alternative leverage measure, (c) Total Debt / EBITDA which compares debt to cash-generation capacity. McDonald\'s, Boeing post-737 MAX, Starbucks at points have had negative book equity due to buybacks — none distressed, but D/E unhelpful.

• What\'s a "covenant" and how does D/E relate?+

  Loan covenants are conditions in the loan agreement that the borrower must maintain. Maintenance covenants require ongoing compliance — e.g. "D/E must remain below 2.5". Breaching triggers default → accelerated repayment or renegotiation. Incurrence covenants only activate at specific events (new debt issuance, dividends, M&A). D/E covenants are typically book-based because book values are auditable and don\'t fluctuate daily with markets. If your firm is approaching a covenant D/E ceiling, that\'s a credit-distress signal even if absolute leverage looks moderate.

• How does D/E feed into WACC?+

  D/E sets the weights in WACC. Recall WACC = (E/V) · re + (D/V) · rd · (1−Tc), where V = D + E. So WACC weights are derived directly from your D/E. Higher D/E → more weight on after-tax cost of debt → lower WACC (because debt is cheaper than equity). But higher D/E also raises rd (lenders demand more for leveraged firms) and raises re (equity becomes riskier with more debt above it). The WACC-D/E relationship is U-shaped: too little debt = expensive WACC (no tax shield); too much debt = expensive WACC (distress costs); optimum somewhere in the middle. See our WACC calculator (RT-FIN-222) to compute the full effect.

• Is preferred stock debt or equity?+

  Technically equity but economically often closer to debt. Cumulative preferred with fixed dividends behaves like perpetual debt — most analysts treat it as debt for capital structure analysis. Convertible preferred straddles depending on the conversion likelihood. Mandatory convertible behaves like equity. For D/E precision, separate preferred stock into a third bucket; for quick analysis, add preferred to either debt or equity based on its dominant economic nature. Most equity research adds preferred to debt for WACC purposes.

• Is anything I enter saved?+

  No. Debt, equity, market cap — every input stays in your browser. Book D/E, market D/E, debt-to-capital, equity multiplier computations all run as client-side JavaScript. Open DevTools → Network when you click Calculate and you\'ll see zero outbound requests. Safe for confidential capital-structure analysis.

• Where can I read more about capital structure?+

  Foundational: Modigliani F, Miller MH "The Cost of Capital, Corporation Finance and the Theory of Investment." American Economic Review 1958. The 1963 follow-up added corporate taxes. Trade-Off Theory: Myers SC "The Capital Structure Puzzle." JoF 1984. Brealey-Myers-Allen, Principles of Corporate Finance, Ch.17-19. Industry benchmarks: Damodaran data archive. ASEAN-specific: MAS, BNM, BI annual financial stability reports cover regional leverage trends.

• How does ASEAN capital structure differ from US?+

  ASEAN firms tend to carry less debt than US peers, for structural reasons: (a) higher local borrowing costs (rd is materially higher), (b) family-controlled firms preferring equity cushion, (c) less-developed corporate bond markets historically (banks dominate), (d) currency-mismatch risk on foreign-currency debt. Singapore: most listed companies 0.2-0.6 D/E except banks and utilities. Malaysia: similar range. Indonesia: 0.4-1.0 with some sectors (state-owned enterprises) higher. Vietnam: younger market, more bank financing, 0.6-1.5 typical. Hong Kong: more developed bond market, leverage closer to US norms.
