How should I interpret the interest coverage ratio, and what level indicates financial distress?

The interest coverage ratio measures a company's ability to service its debt with operating earnings. It is one of the most widely used solvency metrics.

Formula

Interest Coverage = EBIT / Interest Expense

Some variations use EBITDA in the numerator for a cash-focused view:

EBITDA Coverage = EBITDA / Interest Expense

Interpretation Guidelines

Example: Westpoint Engineering reports EBIT of $3,600,000 and interest expense of $2,000,000.

Interest Coverage = $3,600,000 / $2,000,000 = 1.8x

A 1.8x ratio means Westpoint has only $1.80 of operating profit for every $1.00 of interest. A 10% decline in EBIT would drop coverage to 1.62x. A 20% decline would put it at 1.44x -- dangerously close to missing interest payments.

Context Matters

1. Stable industries (utilities, regulated telecom) can operate safely with lower coverage (2-3x) because earnings are predictable.
2. Cyclical industries (mining, construction, airlines) need higher coverage (5-8x) to survive downturns.
3. Growth companies may temporarily have low coverage if they are investing heavily, as long as cash flow supports the debt.

Debt Covenant Triggers

Many loan agreements specify a minimum interest coverage ratio. Common covenant levels are 2.0x to 3.5x. Breaching the covenant can trigger default, acceleration of debt repayment, or renegotiation of terms.

Westpoint at 1.8x is likely below its covenant threshold. If the covenant requires 2.5x, the company is in technical violation and may face:

• Higher interest rates on renegotiated debt
• Requirement to post additional collateral
• Accelerated repayment demands

EBIT vs. EBITDA Coverage

EBITDA coverage is typically higher because it adds back depreciation and amortization. A company with heavy capital expenditures may look safer on an EBITDA basis but still struggle on an EBIT basis. Analysts should use both.

Exam Tip: The CFA exam tests both the calculation and the interpretation. Be prepared to discuss what a declining interest coverage trend signals and how covenant violations affect a company's financial flexibility.
