Interest Coverage Ratio: Measure Debt Risk in 2026

Debt is not automatically bad. But when interest costs explode, even great businesses can struggle. The interest coverage ratio shows whether a company can pay its interest bill safely.

What Is the Interest Coverage Ratio?

It measures how many times a company’s operating profit covers its interest expense.

Interest Coverage = EBIT / Interest Expense

Key idea: the higher the ratio, the safer the company’s debt load.

---

How to Interpret It

Coverage should be compared within the same sector.

---

EBIT vs EBITDA (Which One to Use?)

Some analysts use EBITDA to compute coverage (adds back depreciation). That can be useful for asset‑heavy sectors, but EBIT is more conservative.

Rule of thumb:

• Use EBIT for most companies
• Use EBITDA only if depreciation is unusually large and stable

Red Flags to Watch

1. Coverage Falling for 3+ Years

This suggests debt is growing faster than profits.

2. Rising Interest Costs

If rates rise and coverage is already low, refinancing becomes dangerous.

3. Coverage Boosted by One‑Time Gains

Always check normalized earnings.

Interest Coverage vs FCF and ROIC

Coverage is stronger when combined with:

• Free Cash Flow (guide)
• ROIC (guide)

A company with good coverage but weak FCF is still risky.

Sector Benchmarks (Approx.)

Quick Checklist

• Coverage above 3x for 3+ years
• Debt stable or declining
• Interest expense not accelerating
• FCF positive and stable
• No major refinancing wall in 12–24 months

---

Conclusion

The interest coverage ratio is one of the fastest ways to detect balance‑sheet stress. Combine it with FCF, ROIC, and volatility for a complete risk picture.

Next steps:

• Compare coverage across peers
• Track the trend every quarter
• Stress‑test coverage with higher rates
