Interest Coverage — Debt Servicing Capacity
Learning Objectives
After reading this chapter, you will be able to:
- Apply: ICR = EBIT ÷ Interest Expense — measures how easily company pays interest. More important than raw debt levels. ICR < 1 is critical danger zone. Trend analysis and recession stress-testing essential. Professional analysts ask: "If profit falls 30%, can interest still be paid?"
- Apply Interest Coverage Ratio metrics and formulas using consolidated NSE/BSE annual report data
- Identify red flags when interpreting Interest Coverage Ratio: Interest Coverage < 2
- Connect Interest Coverage Ratio analysis to peer comparison and buy/hold/avoid decisions
Introduction
In the Debt Analysis chapter we learned how to measure leverage. The next question:
"The company has debt — but can it comfortably pay the interest on that debt?"
Interest Coverage Ratio answers exactly that.
Core Concepts
Financial Terms
| Term | Meaning |
|---|---|
| Interest Coverage Ratio (ICR) | EBIT ÷ Interest Expense |
| EBIT | Earnings Before Interest and Tax — Operating Profit |
| Interest Expense | Interest paid on loans |
| Debt Servicing Capacity | Company's ability to pay interest |
| Financial Stress | ICR declining → debt pressure rising |
Investment Decision
| Check | Criteria |
|---|---|
| ICR | > 5 preferred |
| D/E | Controlled |
| Net Debt | Manageable |
| ROCE | > Interest Rate |
| Cash Flow | Strong |
Decision: ICR > 5 + Controlled Debt + Strong Cash Flow → Financially Healthy candidate.
Golden Rule: "Do not look only at Debt — look at Debt Servicing Capacity."
"Having Debt is not the problem — lacking the capacity to service Debt is the problem."
| Item | Amount |
|---|---|
| EBIT | ₹500 Cr |
| Interest Expense | ₹100 Cr |
| ICR | 5× |
Profit is 5× Interest Payment — comfortable position.
| Item | Amount |
|---|---|
| EBIT | ₹200 Cr |
| Interest Expense | ₹150 Cr |
| ICR | 1.33 |
A large share of Profit goes to Interest — concerning.
Salary ₹1 lakh, EMI ₹10,000 → comfortable. EMI ₹90,000 → a small problem can become a crisis. ICR measures the same concept for companies.
| Interest Coverage | Meaning |
|---|---|
| <1 | Extremely dangerous — Operating Profit < Interest |
| 1–2 | Weak |
| 2–3 | Fair |
| 3–5 | Good |
| >5 | Strong |
| >10 | Excellent |
Most Dangerous: ICR < 1 — Company may need Cash Reserves, Asset Sales, or New Loans to pay interest.
Warning Signal:
| Year | ICR |
|---|---|
| 2021 | 8 |
| 2022 | 7 |
| 2023 | 5 |
| 2024 | 3 |
| 2025 | 2 |
Debt pressure rising despite stable D/E possible.
Excellent Trend:
| Year | ICR |
|---|---|
| 2021 | 2 |
| 2022 | 4 |
| 2023 | 6 |
| 2024 | 8 |
| 2025 | 10 |
Profit growing, Debt Management improving.
| Company A | Company B | |
|---|---|---|
| D/E | 1.5 | 0.8 |
| ICR | 10 | 1.5 |
Company A may be better — Debt Servicing Capacity > Debt Quantity.
| Scenario | Loan Cost | ROCE | Verdict |
|---|---|---|---|
| Value Creation | 10% | 20% | Debt beneficial |
| Value Destruction | 12% | 8% | Debt harmful |
Formula & Explanation
Visual Guide
Worked Example — Indian Market
Interest Coverage
EBIT ₹60 Cr, Interest ₹20 Cr → Coverage 3.0x (borderline). Below 2x = high distress risk; pair with debt maturity profile.
Real World Example
Two people, Salary ₹1,00,000/month:
| Person A | Person B | |
|---|---|---|
| Home Loan EMI | ₹10,000 | ₹80,000 |
| Savings | ₹90,000 | ₹20,000 |
| Status | Comfortable | Stressed |
Both have Loans, but Person B carries more risk — a large share of Income goes to Loan Servicing. Companies follow the same logic.
Case Study
| Company | ICR Context |
|---|---|
| TCS | Very high ICR — almost no debt, minimal risk |
| BEL | Strong Cash, Low Debt, High ICR — excellent |
| Maithan Alloys | ICR Trend critical during Commodity Cycle |
| Highly Leveraged Co. | High Debt + Low ICR → extra caution |
Recession Test: Bull markets mask weakness; recession drops Sales/Profit — High ICR companies survive, Low ICR companies struggle.
CFA Exam Tip
Never look at single year — 5-year trend essential. Stress test: "If profit drops 30% next year, can company still pay interest?"
Combine with: D/E, Net Debt, ROCE, Operating Cash Flow, Altman Z-Score
Common Mistakes
- Interest Coverage < 2
- Ratio continuously declining
- Debt rising but EBIT not
- Interest Expense rising rapidly
- New loans to pay old interest (Debt Trap)
- Negative Cash Flow + Low ICR — very dangerous combination
Key Takeaways
ICR = EBIT ÷ Interest Expense — measures how easily company pays interest. More important than raw debt levels. ICR < 1 is critical danger zone. Trend analysis and recession stress-testing essential. Professional analysts ask: "If profit falls 30%, can interest still be paid?"

Answer Key
Q1 (Conceptual)
ICR = EBIT ÷ Interest Expense — measures debt servicing capacity; trend and stress-testing matter more than a single-year snapshot.
Q2 (Calculate)
20% ROE
Q3 (Application)
Both must align — strong Interest Coverage Ratio (ICR) with weak EBIT (or vice versa) needs deeper AR review.
Q4 (Red Flag)
Interest Coverage < 2 — triangulate with cash flow and balance sheet.
Q5 (CFA Style)
Never look at single year — 5-year trend essential. Stress test: "If profit drops 30% next year, can company still pay interest?"
Q6 (Decision)
Justify with metric trend + valuation + balance-sheet quality; one ratio never enough.
Q7 (Lab)
See Part 03 Practice Lab and verify with lab Answer Key.

FAQ {#faq}
Q: What should I check alongside Interest Coverage evaluation?
A: ICR declining consistently — triangulate with D/E, Net Debt, and cash flow.
Q: How do I connect Interest Coverage theory to Indian market practice?
A: Use Screener/Trendlyne + company annual reports — plot the same metrics over 3 years; paper formulas alone are insufficient.
Q: Why avoid relying on Interest Coverage below 2?
A: Low coverage leaves little buffer if earnings fall — one ratio is never enough.
Q: Why is rising Debt without rising EBIT a red flag?
A: Debt servicing pressure may be building even if headline leverage looks stable.
Q: How do I drill this chapter's concepts in the Practice Lab?
A: Open Part 03 Practice Lab → use the FAQ Drill row for interest-coverage-ratio to practice on real stocks, then verify answers against the Chapter FAQ Quick Index.
