Formula
Debt-to-Capital = Total Debt / (Total Debt + Shareholders' Equity)
Also written as: D / (D + E) where D = total debt and E = shareholders' equity.
How it works
The debt-to-capital ratio expresses debt as a proportion of a company's total capital base, which is the sum of debt and equity. Unlike the debt-to-asset ratio, it focuses purely on the financing mix rather than comparing to assets.
This ratio is widely used in credit analysis and capital structure decisions, with higher values indicating greater reliance on borrowed funds.
Worked example
Company with $40,000 Debt and $60,000 Equity
- Total capital = Debt + Equity = $40,000 + $60,000 = $100,000
- Debt-to-Capital = $40,000 / $100,000 = 0.40
A ratio of 0.40 (40%) indicates 40% debt financing and 60% equity financing — a moderately conservative capital structure.
Common mistakes to avoid
- Using only long-term debt instead of total debt (short-term + long-term) in the numerator, understating leverage for companies with large revolving credit or commercial paper programs.
- Including minority interest or deferred revenue in equity, inflating the equity base and understating the debt-to-capital ratio.
- Confusing debt-to-capital with debt-to-equity -- debt-to-capital is bounded between 0 and 1; debt-to-equity has no upper bound and can exceed 1.
Key terms
- What is total capital?
- Total capital is the sum of all long-term debt and shareholders' equity, representing the permanent or long-term financing of the business.
- What is a healthy debt-to-capital ratio?
- Most analysts consider ratios below 0.5 (50%) as acceptable, indicating that equity exceeds debt. Capital-intensive industries often carry higher ratios.
- How does debt-to-capital differ from debt-to-equity?
- Debt-to-capital places debt over total capital (D+E), giving a value between 0 and 1. Debt-to-equity places debt over equity alone, and can exceed 1 when debt exceeds equity.
Frequently asked questions
- What is the practical difference between debt-to-capital and debt-to-equity?
- Debt-to-capital expresses debt as a fraction of total funding (0 to 1). Debt-to-equity expresses debt relative to equity alone (0 to infinity). Debt-to-capital is easier to interpret at a glance.
- How does debt-to-capital relate to WACC?
- The debt weight in WACC (D/V) is exactly the debt-to-capital ratio. A higher ratio increases the weight of lower-cost (tax-shielded) debt, often reducing WACC up to the point where financial distress risk begins to raise borrowing costs.
- What debt-to-capital ratio do investment-grade companies target?
- Most BBB-and-above companies target below 50-60%. Leveraged buyout targets often exceed 70-80% post-acquisition, with plans to delever using operating cash flow over time.
