What Is the Debt-to-Equity Ratio and How Do You Calculate It?
Debt-to-equity (D/E) is one of the most widely used measures of financial leverage. Here is how to calculate it, what a healthy range looks like, and how it changes across industries.
The debt-to-equity ratio compares how much a company has borrowed to how much shareholders have invested. It's a quick indicator of financial risk — but only meaningful in the context of the industry.
The Basic Calculation
D/E Ratio = Total Debt / Total Shareholders' Equity
Total Debt = all interest-bearing liabilities
(Bank loans, bonds, finance leases, overdrafts)
Excludes: trade payables, tax liabilities (these are operating liabilities)
Total Equity = all shareholders' equity on the balance sheet
(Share capital + retained earnings + other reserves)
Example from a company balance sheet:
Long-term debt: £850,000
Short-term bank borrowings: £150,000
Total debt: £1,000,000
Share capital: £200,000
Retained earnings: £800,000
Total equity: £1,000,000
D/E = £1,000,000 / £1,000,000 = 1.0
Interpreting the D/E Ratio
D/E = 0: no debt (entirely equity-financed)
D/E < 1: more equity than debt (conservative leverage)
D/E = 1: equal debt and equity
D/E > 1: more debt than equity (leveraged)
D/E > 3: highly leveraged (significant financial risk in downturns)
Context is everything:
D/E of 2.0 for a utility company: normal (stable cash flows support debt)
D/E of 2.0 for a tech startup: alarming (volatile revenues, high risk)
D/E of 4.0 for a bank: typical (banks lend out deposits = high leverage by design)
Industry D/E Benchmarks
SectorTypical D/E RangeReason
Technology (growth)0.1-0.5Asset-light, funded by equity
Consumer goods0.5-1.5Moderate, stable cash flows
Utilities1.5-3.0Predictable revenues support high debt
Real estate (REITs)1.0-2.5Property assets collateralise debt
Financial services5.0-15.0Leverage is core to the business model
Net D/E: A More Useful Variant
Net Debt = Total Debt - Cash and Cash Equivalents
Net D/E = Net Debt / Equity
A company with £1m debt but £800k cash:
Net debt: £200,000
Net D/E = £200,000 / £1,000,000 = 0.2 (much lower risk than gross D/E of 1.0)
"Net cash" position: when cash > debt, net D/E is negative
Many large tech companies are in net cash positions
(Apple, Microsoft, Alphabet — technically no net debt)
Net D/E is preferred by analysts because it reflects the ability
to repay debt immediately from available cash.
