Leverage & Coverage Ratios Explained
After Profitability Metrics & Margins Explained, the next credit question is not just whether a company earns profits, but how much debt it carries and whether its cash flows can service it. Leverage and coverage ratios form the core credit-risk toolkit for judging financial leverage, operating cash flow support, interest burden, debt service, and collateral coverage. In interviews, these ratios help you move from formula recall to a clear risk interpretation.
- Debt/Equity (D/E) = Total Debt / Shareholders' Equity, with < 1x preferred and ≤ 2x acceptable for capital-intensive businesses.
- Net Debt/EBITDA = (Total Debt - Cash) / EBITDA; < 3x is healthy, > 4x is stressed, and banks flag > 5x.
- Interest Coverage (ICR) = EBIT / Interest Expense; > 3x is comfortable and < 1.5x is a distress signal.
- DSCR = (EBITDA - Capex - Tax) / (Principal + Interest); > 1.25x is used for project finance.
- Asset Coverage Ratio = (Total Assets - Intangibles - CL) / Total Debt; > 1.5x gives bank comfort.
- High D/E means more risk but potential higher ROE, while lower ICR means higher default risk.
Leverage and Coverage Ratios in Credit Risk
Leverage ratios measure financial leverage, while coverage ratios test whether earnings and cash flows can service the debt burden. The big picture is simple: first check how much debt exists, then check whether operating cash flow, interest coverage, project cash flows, and collateral coverage are strong enough for lenders.
IL&FS subsidiaries had ICR < 1x before crisis. Since Interest Coverage is EBIT / Interest Expense, a level below 1x signals that operating earnings are not covering interest expense, which is why lower ICR = higher default risk.
Debt/Equity (D/E)
Debt/Equity (D/E) is calculated as Total Debt / Shareholders' Equity. It measures financial leverage.
The preferred threshold is < 1x, while ≤ 2x is acceptable for capital-intensive businesses. The interpretation is direct: high D/E = more risk but potential higher ROE.
Net Debt/EBITDA
Net Debt/EBITDA is calculated as (Total Debt - Cash) / EBITDA. It is a key credit metric.
The ratio shows how many years of operating cash flow to repay debt. A level < 3x is healthy, > 4x is stressed, and banks flag > 5x.
Interest Coverage (ICR)
Interest Coverage (ICR) is calculated as EBIT / Interest Expense. It focuses on whether operating profit is enough to meet interest obligations.
A level > 3x is comfortable, while < 1.5x is a distress signal. Lower ICR = higher default risk.
DSCR
DSCR is calculated as (EBITDA - Capex - Tax) / (Principal + Interest). It stands for Debt Service Coverage Ratio.
The benchmark is > 1.25x for project finance. DSCR is critical for infrastructure and project lending because it compares cash flow available after capex and tax against principal plus interest.
Asset Coverage Ratio
Asset Coverage Ratio is calculated as (Total Assets - Intangibles - CL) / Total Debt. It measures collateral coverage.
A level > 1.5x gives bank comfort. This ratio is important for secured lending decisions because lenders care not only about repayment capacity, but also about asset backing.
Structuring a Leverage & Coverage Ratios Explained Interview Answer
"How would you use leverage and coverage ratios to judge a company's credit risk?"
The strongest answers do not stop at D/E. Move from debt level to repayment capacity: Net Debt/EBITDA, ICR, DSCR, and Asset Coverage together show whether the company can comfortably service debt.
The most frequent error is treating one threshold as universally sufficient. D/E may be ≤ 2x acceptable for capital-intensive businesses, but a weak ICR, stressed Net Debt/EBITDA, low DSCR, or poor Asset Coverage can still signal credit risk.
Conclusion
Leverage and coverage ratios are the core credit-risk toolkit: they show how much debt a company carries, how many years of operating cash flow may be needed to repay it, whether interest and debt service are covered, and whether collateral gives lender comfort.
