Debt to equity by industry is useful only when peers share a clear debt definition, equity basis and reporting date. Build a comparable peer workbook, calculate a median and pooled ratio, and explain changes caused by the equity denominator.
Debt to equity by industry compares a company's defined debt balance with shareholders' equity among suitable peers. The comparison needs a shared numerator, denominator and reporting date before an industry average means anything. Use it to investigate differences in financing and capital structure, then assess the company's own cash obligations separately.
Debt to equity ratio used here = Interest-bearing borrowings and finance lease liabilities / Total book shareholders' equity
This article excludes operating lease liabilities, trade payables and other nonborrowed liabilities. That is a stated analytical convention, not a universal accounting definition. The SEC's financial statements guide, for example, presents debt to equity using total liabilities divided by shareholders' equity. Both numerators can be useful, but mixing them destroys comparability.
Put the definition above the peer table. Specify whether preferred equity and noncontrolling interests are included in the denominator. Use consolidated figures on both sides, with the same treatment for each company.
Book equity is not market capitalization. A workbook mixing those bases can make a share-price movement look like a change in balance-sheet financing. Use the debt to equity ratio guide for the underlying calculation, then keep this comparison focused on matching peers and interpreting the distribution.
Start with companies doing similar work. The Census Bureau explains NAICS as a classification of establishments based on their production processes. A shared classification is a useful starting filter; it does not guarantee that whole companies have the same business mix or funding needs.
For every candidate, record the main activity, business size, reporting period, accounting basis, acquisition history and ownership structure. A manufacturer that owns its facilities may have different financing from a peer outsourcing production. A diversified parent can carry a financing subsidiary that a pure operating company lacks.
| Business characteristic | Why it affects comparability | What to record in the workbook |
|---|---|---|
| Owned plants and equipment | Borrowing may fund long-lived operating assets | Asset ownership and lease policy |
| Seasonal inventory | Short-term debt can peak before sales turn into cash | Fiscal close and seasonal position |
| Recurring service contracts | Cash timing can differ from a goods business | Billing and collection structure |
| Acquisitions or distributions | Debt and equity may change independently of operations | Material capital transactions |
Keep banks outside this operating-company table; bank debt to equity needs its own treatment. For the specific manufacturing sector, the aerospace and defense comparison addresses a different peer boundary.
The following companies are illustrative US industrial parts manufacturers, all measured on September 30, 2026. They are selected teaching examples, not published industry averages. Debt includes finance leases and excludes operating leases under the convention above; equity is positive consolidated book equity.
| Peer | Short-term borrowings (USD) | Long-term borrowings (USD) | Finance leases (USD) | Included debt (USD) | Book equity (USD) | Debt/equity |
|---|---|---|---|---|---|---|
| Manufacturer A | 1,000,000 | 3,000,000 | 1,000,000 | 5,000,000 | 5,000,000 | 1.00x |
| Manufacturer B | 600,000 | 1,400,000 | 0 | 2,000,000 | 4,000,000 | 0.50x |
| Manufacturer C | 500,000 | 1,500,000 | 0 | 2,000,000 | 1,000,000 | 2.00x |
| Peer totals | 2,100,000 | 5,900,000 | 1,000,000 | 9,000,000 | 10,000,000 | 0.90x pooled |
For each row, add the borrowing and lease columns, then divide by equity. Manufacturer A is (1,000,000 + 3,000,000 + 1,000,000) / 5,000,000 = 1.00x. Manufacturer C has less debt than A but a higher ratio because its equity base is much smaller.
The totals prove the numerator: 2,100,000 + 5,900,000 + 1,000,000 = $9,000,000. Each company's included debt must also reconcile to its balance sheet and supporting notes before it enters a peer statistic.
| Peer summary | Calculation | Result |
|---|---|---|
| Median company ratio | Middle of 0.50, 1.00 and 2.00 | 1.00x |
| Simple mean company ratio | (0.50 + 1.00 + 2.00) / 3 | 1.17x |
| Pooled debt/equity | 9,000,000 / 10,000,000 | 0.90x |
Ratios are rounded to two decimal places after calculation. The simple mean is 1.166666... before rounding.
The median describes the middle selected business. The pooled figure describes all selected debt relative to all selected equity. As a cross-check, the equity-weighted calculation gives the same pooled result: (5,000,000 × 1.00 + 4,000,000 × 0.50 + 1,000,000 × 2.00) / 10,000,000 = 0.90x.
Suppose your company sits outside the peer sample with the following balances. The second column shows an independent cash-funded share repurchase, assuming no other change.
| Balance or calculation | Original close | After repurchase |
|---|---|---|
| Short-term borrowings (USD) | 500,000 | 500,000 |
| Long-term borrowings (USD) | 2,250,000 | 2,250,000 |
| Finance leases (USD) | 250,000 | 250,000 |
| Included debt (USD) | 3,000,000 | 3,000,000 |
| Cash-funded repurchase reducing equity (USD) | 0 | 500,000 |
| Book equity (USD) | 2,500,000 | 2,000,000 |
| Debt/equity | 1.20x | 1.50x |
The original 1.20x exceeds the selected peer median of 1.00x. After the repurchase, 3,000,000 / (2,500,000 − 500,000) = 1.50x, although debt is unchanged. A borrowing explanation would miss the denominator movement.
If cash balances differ materially across peers, compare net debt to equity separately under one eligibility policy. Do not subtract cash for selected companies while leaving everyone else on gross debt.
Finance should own the definition and reconciliation. Treasury can explain borrowing and cash movements; the controller can explain equity transactions and reporting classifications. The resulting review should identify why the gap exists and which obligations need attention, rather than declare that the company must match a median.
Bring a peer balance-sheet workbook with reporting dates, debt components, equity and inclusion decisions. Covirage maps the columns, its tools compute and check the consistent ratios, and the external AI model explains the comparison with every figure traced to its rows. Create a free Covirage account and bring a sample of your own data; account creation takes about a minute.
See the file-based approach for finance teams.
Start with a dated set of comparable businesses and a consistent calculation. Then examine cash generation, debt maturities and equity movements. A peer median shows the center of that selected group; it does not establish the borrowing level your business can sustain.
A median describes the middle company and is less affected by unusually high ratios. A simple average gives each company equal weight. A pooled ratio divides combined debt by combined equity. Label the statistic because each answers a different question.
They belong if the published definition uses total liabilities. They do not belong in a measure defined as interest-bearing borrowings and specified lease liabilities. Read the source methodology and recalculate peers on one basis before comparing their reported ratios.
Show them separately and explain the exclusion from any positive-equity peer statistic. A negative ratio caused by negative equity does not indicate low leverage. Record how many companies were excluded so readers can judge whether the remaining group is representative.
