What Is the Debt/Equity Ratio?
The Debt/Equity Ratio (D/E) measures the extent to which a company uses borrowed money compared to its own capital. It tells you how much debt the company carries for every dollar of shareholders' equity.
Formula:
D/E = Total Liabilities / Shareholders' Equity
A D/E below 1 means the company owes less than its equity — generally considered safe. A D/E above 2 indicates heavy reliance on debt — higher risk, but potentially higher returns if the business performs well.
Simple Explanation
You buy a house worth $300,000:
- Scenario A: You put down $200,000 and borrow $100,000. D/E = 0.5 (safe, manageable repayments)
- Scenario B: You put down $100,000 and borrow $200,000. D/E = 2.0 (high risk, heavy debt burden)
Both scenarios result in owning the same $300,000 house, but the person in Scenario B faces serious trouble if their income drops — they still must make interest payments regardless of economic conditions. D/E in business works the same way: high debt creates pressure from interest expenses, especially when revenue declines.
Real-World Example
Comparing D/E ratios of 3 listed real estate companies in Vietnam:
| Stock | Total Debt | Equity | D/E |
|---|---|---|---|
| VHM (Vinhomes) | 95,000B VND | 65,000B VND | 1.46 |
| NVL (Novaland) | 120,000B VND | 30,000B VND | 4.00 |
| KDH (Khang Dien) | 8,000B VND | 15,000B VND | 0.53 |
Analysis:
- KDH has the lowest D/E (0.53) — conservative capital structure with minimal financial risk. However, expansion may be slower.
- VHM sits at a moderate level (1.46) — reasonable for real estate, which is capital-intensive.
- NVL has a very high D/E (4.0) — debt is 4 times equity, creating significant risk if the property market stalls.
Note: These figures are illustrative. Always check the latest actual data.
D/E by Industry
Not all high D/E is bad — each industry has its own normal range:
- Banking: D/E of 8-12 is normal (they lend out depositors' money by nature)
- Real estate: D/E of 1-3 is common (capital-intensive project development)
- Technology / Consumer: D/E below 1 is ideal (asset-light business models)
Always compare D/E within the same sector — do not compare a bank to a tech company.
Why It Matters for Investors
Assessing bankruptcy risk. Companies with excessively high D/E face severe danger during economic downturns. In 2022-2023, many Vietnamese real estate companies with D/E above 3 experienced serious liquidity crises when the bond market froze.
Understanding leverage. High D/E means greater leverage. When business is good, leverage amplifies profits (high ROE). When things turn bad, leverage amplifies losses. Understanding D/E helps you assess whether "high ROE" comes from strong operations or simply from heavy borrowing.
A safety filter. When screening stocks, D/E is an effective risk filter. Eliminating companies with excessive D/E helps you focus on businesses with solid financial foundations.
