Solvency Ratios (Debt-Equity, Interest Coverage)

Picture this: a bank is deciding whether to give Rajesh & Co. Pvt. Ltd. a ₹5 crore term loan. They don't just care about this year's profit — they want to know if the company can survive long enough to repay. That's exactly what solvency ratios tell you: can this business meet its long-term obligations? These ratios are the lender's lens, and your job in the exam is to calculate and interpret them correctly.

The four solvency ratios you must know cold for May 2026 are:

1. Debt-Equity Ratio = Long-Term Debt ÷ Shareholders' Funds. A ratio of 2:1 means for every ₹2 borrowed long-term, shareholders have contributed ₹1. Lower is safer for lenders; higher means more financial risk. Banks typically prefer this below 2:1.

2. Total Debt to Total Assets Ratio (also called Debt Ratio) = Total Debt ÷ Total Assets. Shows what proportion of assets are financed by debt. A ratio of 0.6 means 60% of assets are funded by borrowings — risky territory.

3. Interest Coverage Ratio (ICR) = EBIT ÷ Interest Expense. This is the star of exam questions. EBIT = Earnings Before Interest & Tax = Net Profit + Interest + Tax. An ICR of 5x means profits can cover interest 5 times over. Below 2x is generally a red flag.

4. Proprietary Ratio = Shareholders' Funds ÷ Total Assets. The flip side of the Debt Ratio — shows what proportion of assets owners actually own. Higher = more solvent.

A critical distinction: liquidity ratios (Current Ratio, Quick Ratio) cover short-term survival; solvency ratios cover long-term survival. Don't mix them up in a question asking you to comment on 'long-term financial health.'

The interpretation always matters more than the number alone. A Debt-Equity Ratio of 3:1 might be perfectly fine for an infrastructure company (stable, long-term cash flows) but alarming for a trading firm. Always tie your answer to the nature of the business and industry norms — examiners love this nuance in 6-mark analysis questions.

Worked example

Example 1 — Interest Coverage Ratio

The Balance Sheet and P&L of Sharma Industries Ltd. show: Net Profit after tax = ₹18,00,000; Tax = ₹6,00,000; Interest on long-term loans = ₹4,00,000.

Working:

  • EBIT = Net Profit + Tax + Interest = ₹18,00,000 + ₹6,00,000 + ₹4,00,000 = ₹28,00,000
  • Interest Expense = ₹4,00,000
  • ICR = ₹28,00,000 ÷ ₹4,00,000 = 7 times

Answer: ICR = 7x. Interpretation: Sharma Industries earns ₹7 for every ₹1 of interest it owes — excellent solvency position; low risk for lenders.

Example 2 — Debt-Equity Ratio & Proprietary Ratio

From Ms. Iyer's company balance sheet: Equity Share Capital = ₹20,00,000; Reserves & Surplus = ₹10,00,000; 12% Debentures = ₹15,00,000; Long-term Bank Loan = ₹15,00,000; Total Assets = ₹70,00,000.

Working:

  • Shareholders' Funds = ₹20,00,000 + ₹10,00,000 = ₹30,00,000
  • Long-Term Debt = ₹15,00,000 + ₹15,00,000 = ₹30,00,000
  • Debt-Equity Ratio = ₹30,00,000 ÷ ₹30,00,000 = 1:1
  • Proprietary Ratio = ₹30,00,000 ÷ ₹70,00,000 = 0.43 or 43%

Answer: D/E = 1:1 (healthy); Proprietary Ratio = 0.43 (owners finance 43% of assets — moderate risk).

⚠️ Common exam mistakes

  • Using Net Profit instead of EBIT for ICR. Don't forget to add back tax AND interest to arrive at EBIT. The formula is Net Profit after tax + Tax + Interest — students frequently skip adding tax back.
  • Including short-term borrowings in the Debt-Equity Ratio. Only long-term debt (debentures, long-term loans) goes in the numerator. Bank overdraft and creditors are current liabilities, not long-term debt.
  • Confusing Debt-Equity Ratio with Capital Gearing Ratio. Capital Gearing compares fixed-interest capital to equity; Debt-Equity uses total long-term debt. Read the question carefully for which one is asked.
  • Skipping interpretation in 6-mark questions. Calculating the ratio and stopping earns only partial marks. Always write one sentence on what the ratio means and whether it is favourable — examiners have explicit marking for 'comment/interpretation.'
  • Treating Preference Share Capital as part of Shareholders' Funds inconsistently. For solvency analysis, preference shares can be treated as debt (fixed obligation) or equity depending on the question's instruction. If the question is silent, include it in Shareholders' Funds — but flag it if asked to comment on financial risk.
