The debt to capital ratio shows debt as a share of debt plus equity. Calculate it from a balance-sheet export, reconcile the inputs, and distinguish financing changes from changes in retained earnings.
The debt to capital ratio is debt divided by debt plus shareholders' equity. It shows the share of the defined capital base provided by debt: $3,000,000 of debt and $4,500,000 of equity produce a 40.0% ratio. Start with a consistent debt definition, because including every liability answers a different question.
Debt to capital ratio = Total debt / (Total debt + Shareholders' equity)
Capital = Total debt + Shareholders' equity
For a balance-sheet comparison, use book values for both inputs at the same reporting date. Aswath Damodaran's financial definitions give the book debt ratio as book debt divided by book debt plus book equity, and distinguish it from a market-value ratio. Changing the equity basis changes the measure even when borrowing stays constant.
Here, debt includes short-term borrowings, current maturities of long-term borrowings, noncurrent borrowings, and recognized finance and operating lease liabilities. Ordinary trade payables, accrued wages, taxes payable, and deferred revenue remain outside debt. Record this policy beside the calculation; a credit agreement or peer dataset may use another scope.
The debt ratio uses an asset denominator. Keep that separate from the capital denominator here, and use solvency ratios when the question is whether cash generation supports the obligations.
Use the balance-sheet workbook and debt schedule for the same entity and date. Keep the account code, account description, closing balance, currency, consolidation status, and mapping to debt, equity, or excluded liabilities. Borrowings split between current and noncurrent sections must appear once each.
This illustrative US manufacturer's September 30, 2026 export contains these balances. Amounts are USD; percentages throughout are rounded to two decimal places unless a table shows one.
| Balance-sheet row | Closing balance (USD) | Calculation treatment |
|---|---|---|
| Revolving credit facility | 300,000 | Debt |
| Current maturities of term debt | 200,000 | Debt |
| Noncurrent term debt and notes | 2,100,000 | Debt |
| Current and noncurrent lease liabilities | 400,000 | Debt |
| Trade payables and other liabilities | 1,500,000 | Excluded from debt |
| Shareholders' equity | 4,500,000 | Equity |
| Total assets | 9,000,000 | Reconciliation only |
Do not add the current maturities again if the debt schedule already reports a total including them. Likewise, a schedule headed total lease liabilities may already contain both maturity classifications. The mapping is what prevents the same obligation entering twice.
| Step | Calculation | Result |
|---|---|---|
| Total debt (USD) | 300,000 + 200,000 + 2,100,000 + 400,000 | 3,000,000 |
| Capital (USD) | 3,000,000 + 4,500,000 | 7,500,000 |
| Debt share | 3,000,000 / 7,500,000 | 40.0% |
| Equity share | 4,500,000 / 7,500,000 | 60.0% |
| Total liabilities (USD) | 3,000,000 + 1,500,000 | 4,500,000 |
| Balance-sheet check (USD) | 9,000,000 - 4,500,000 - 4,500,000 | 0 |
The first proof is 40.0% + 60.0% = 100.0%. The second is that assets equal liabilities plus equity, the identity explained in the SEC's guide to financial statements. Debt plus equity is only $7,500,000 here because the $1,500,000 of excluded liabilities still funds part of the $9,000,000 asset base.
If total debt is in B2 and equity in C2, the spreadsheet formula is:
=IF(B2+C2<=0,NA(),B2/(B2+C2))
Format the result as a percentage. Add a separate negative-equity flag: a positive denominator alone does not make a company with negative equity comparable with ordinary positive-equity peers.
Suppose the manufacturer has a separate distribution subsidiary. These balances are already adjusted for intercompany eliminations and use the same debt policy.
| Entity | Debt (USD) | Equity (USD) | Capital (USD) | Debt share |
|---|---|---|---|---|
| Manufacturing | 3,000,000 | 4,500,000 | 7,500,000 | 40.00% |
| Distribution | 1,000,000 | 3,000,000 | 4,000,000 | 25.00% |
| Consolidated | 4,000,000 | 7,500,000 | 11,500,000 | 34.78% |
The consolidated result is 4,000,000 / 11,500,000 = 34.78%. The simple average, (40.00% + 25.00%) / 2 = 32.50%, describes the average entity but does not describe consolidated funding. The distinction is the same one covered in count-weighted and value-weighted measures.
Use translated debt and equity balances from the same approved consolidation workbook under the finance team's translation policy. Do not mix workbook versions.
Return to the manufacturer's $3,000,000 debt and $4,500,000 equity. Each scenario below changes only the stated input from that starting point.
| Separate scenario | Debt (USD) | Equity (USD) | Capital (USD) | Debt share |
|---|---|---|---|---|
| Starting position | 3,000,000 | 4,500,000 | 7,500,000 | 40.00% |
| Borrow 1,000,000 | 4,000,000 | 4,500,000 | 8,500,000 | 47.06% |
| Retain 500,000 of earnings | 3,000,000 | 5,000,000 | 8,000,000 | 37.50% |
| Repay 500,000 of principal with cash | 2,500,000 | 4,500,000 | 7,000,000 | 35.71% |
A falling ratio can reflect accumulated earnings without any principal repayment. A rising ratio can reflect a dividend, repurchase, or loss that reduces equity without any new borrowing. Build separate debt and equity bridges before attributing a change to treasury decisions.
There is no universal good percentage. Compare borrowing terms and cash generation, then use a dated, consistently defined debt-to-capital industry comparison. The ratio itself does not show the maturity schedule, available cash, interest burden, or the investment funded by the borrowing.
Upload your balance-sheet workbook and debt schedule with the mapped balances. Covirage maps the columns; its tools compute the debt shares and check the balances, and the external AI model explains the changes with every figure traced to its rows.

A lower ratio indicates less debt relative to the defined capital base. Whether that is desirable depends on cash generation, debt maturities, borrowing terms, and the company's investment needs. It cannot establish that debt service is affordable or that capital is being used well.
Under the financing definition used here, ordinary trade payables do not count as debt. Include interest-bearing borrowings and the lease liabilities specified in your policy. Keep a mapping from each included balance-sheet account to the debt total so the definition stays consistent.
Yes, book equity can be negative. Debt divided by a positive but smaller capital denominator can then exceed 100%. If debt plus equity is zero or negative, flag the ratio as unsuitable for ordinary comparisons and show the underlying balances.
Subtracting cash changes the numerator to net debt and requires a clearly labeled net-debt measure. This article uses gross debt. A cash-rich company can therefore have a substantial gross debt share while retaining cash that matters for a separate liquidity assessment.
