Formulas and worked example

  • Total Debt = $\text{Short-Term Debt} + \text{Long-Term Debt} + \text{Lease Liabilities}$
  • Net Debt = $\text{Total Debt} - \text{Cash & Cash Equivalents}$
  • Total Book Capital = $\text{Total Debt} + \text{Book Equity}$
  • Total Market Capital = $\text{Total Debt} + \text{Market Capitalization}$
  • Book Debt-to-Capital (%) = $(\text{Total Debt} / \text{Total Book Capital}) \times 100\%$
  • Market Debt-to-Capital (%) = $(\text{Total Debt} / \text{Total Market Capital}) \times 100\%$
  • Net Debt-to-Capital (%) = $[\text{Net Debt} / (\text{Net Debt} + \text{Book Equity})] \times 100\%$
  • Maximum Debt at Covenant = $[\text{Covenant \%} / (100\% - \text{Covenant \%})] \times \text{Book Equity}$
  • Borrowing Headroom = $\text{Maximum Debt at Covenant} - \text{Total Debt}$

An enterprise carries $50.0 million in short-term bank credit, $450.0 million in senior long-term bonds, and $100.0 million in capitalized lease liabilities ($600.0M total funded debt). It holds $300.0 million in cash and short-term securities ($300.0M net debt), with $1,400.0 million in book equity ($2,000.0M total book capital) and $3,400.0 million in market capitalization ($4,000.0M total market capital). The Book Debt-to-Capital Ratio is 30.00% ($600M / $2,000M), while the Market Debt-to-Capital Ratio is 15.00% ($600M / $4,000M). Net Debt-to-Capital is 17.65% ($300M / $1,700M). Under a 45.0% bank loan covenant ceiling, the maximum debt allowed against $1,400M equity is $1,145.45 million ($1,400M × 0.45 / 0.55), providing $545.45 million in incremental borrowing headroom.

Frequently asked questions

What is the Debt-to-Capital Ratio and how is it calculated?

The Debt-to-Capital Ratio measures the proportion of a company's total capital structure funded by debt obligations. It is calculated as: Debt-to-Capital = Total Debt / (Total Debt + Shareholders' Equity). Total debt includes short-term notes, long-term bonds, and capitalized lease obligations. It represents the exact debt weight (w_d) utilized in WACC calculations.

What is the difference between Book Debt-to-Capital and Market Debt-to-Capital?

Book Debt-to-Capital uses balance sheet carrying equity, making it the primary metric monitored by commercial bank loan covenants. Market Debt-to-Capital substitutes market capitalization for book equity, providing institutional investors and rating agencies with a real-time assessment of financial risk and debt service capacity based on market enterprise pricing.

How does Debt-to-Capital differ from the Debt-to-Equity (D/E) ratio?

Debt-to-Equity compares debt directly against equity and can range from zero to infinity (or become mathematically distorted when equity is negative). By contrast, Debt-to-Capital is bounded between 0% and 100%, expressing debt as a percentage of total capitalization, making it directly comparable across capital structures and industry peers.

What constitutes a healthy Debt-to-Capital ratio for corporate solvency?

An investment-grade debt-to-capital ratio typically ranges between 20% and 40%. A ratio below 20% indicates conservative, under-leveraged financing, while ratios between 45% and 60% are typical for capital-intensive utilities. Ratios exceeding 65% are considered speculative or high-yield, indicating significant default risk and limited borrowing capacity.
