Debt-to-Equity Ratio: Definition, Calculation, and Sector Norms

Definition

The Debt-to-Equity (D/E) ratio quantifies a company’s financial leverage by comparing total debt obligations to capital contributed or retained by shareholders:

D/E = Total Debt ÷ Total Shareholders’ Equity

“Total Debt” includes short-term borrowings, current portion of long-term debt, long-term borrowings, and lease liabilities recognised under Ind AS 116 (effective 1 April 2019 for Indian listed companies). Some analysts use Net Debt (total debt minus cash and cash equivalents). The denominator is total shareholders’ equity from the Ind AS balance sheet — paid-up capital plus reserves. A D/E of 1.0 means the company owes ₹1 in debt for every ₹1 of equity.

How It Is Computed

From the Ind AS balance sheet (SEBI LODR 2015 Regulation 33/34):

1. Total Debt: Note disclosures for Borrowings (Non-Current + Current) + Lease Liabilities (Non-Current + Current) as required by Ind AS 116 and Ind AS 107.
2. Shareholders’ Equity: Total Equity line from the Ind AS Schedule III balance sheet — includes equity share capital, other equity (reserves), and non-controlling interest if consolidated.

For financial sector firms (banks, NBFCs), borrowings include deposits and repo borrowings — making D/E of 5–12× structurally normal and incomparable to non-financial firms. RBI uses Capital Adequacy Ratio (Basel III) not D/E for bank leverage monitoring.

What High/Low Values Signal

Modigliani & Miller (1958) established that in perfect markets, capital structure is irrelevant to firm value. In reality, interest is tax-deductible (creating a “tax shield”) but excess debt increases financial distress costs. Myers & Majluf (1984) formulated the Pecking Order theory. Empirical work finds an inverse relationship between leverage and subsequent stock returns in India (Dhankar & Singh 2005). High D/E signals amplified earnings sensitivity to revenue changes; low D/E can indicate conservative management, asset-light models, or underutilised debt capacity.

The historical academic literature documents that firms at extreme leverage (D/E above 3× in non-financial sectors) face significantly higher credit spreads and distress risk (Altman Z-Score framework, 1968).

Sector Dependency

• IT Services (TCS, Infosys, Wipro): D/E 0.0–0.1×. Asset-light, high-FCF.
• FMCG (HUL, Nestle India): D/E 0.0–0.5×.
• Telecom (Bharti Airtel): D/E 2–4× including spectrum debt and Ind AS 116 lease liabilities.
• Infrastructure / Power (NTPC, L&T): D/E 1–3× via project finance — normal and expected.
• Auto OEMs (Maruti, Tata Motors): 0.5–1.5× at OEM level; auto finance subsidiaries much higher.
• Banks / NBFCs: D/E inapplicable; use Capital Adequacy Ratio per RBI guidelines.

Worked Example

Bharti Airtel Ltd (NSE: BHARTIARTL) — FY2025 consolidated Ind AS balance sheet (BSE filing, May 2025)

Approximate figures from BSE disclosure:

• Total Borrowings + Lease Liabilities: approximately ₹2,45,000 crore
• Total Shareholders’ Equity (attributable to owners): approximately ₹82,000 crore

D/E ≈ ₹2,45,000 Cr ÷ ₹82,000 Cr ≈ 2.99×

This reflects capital-intensive telecom: spectrum liabilities (5G/4G auctions), tower infrastructure, and submarine cable assets. Excluding lease liabilities, financial-debt-only D/E is approximately 2.2× — common in telecom globally. EBITDA (~₹75,000 crore) implies Net Debt/EBITDA of approximately 3.3× — the metric lenders focus on alongside D/E. Verify with current BSE filings.

Caveats

• Off-balance-sheet obligations: Before Ind AS 116, operating leases were off-balance-sheet. Their capitalisation significantly raised D/E for airlines, retailers, and telecom post-2019.
• Consolidated vs. standalone: Subsidiaries with large debt can dramatically alter consolidated D/E versus standalone. Financial conglomerates are particularly affected.
• Book vs. market equity: Using market capitalisation in the denominator gives “market D/E” which fluctuates with stock price. Both measures serve different analytical purposes.
• Sector comparability: Never compare D/E of a bank with a FMCG company; and within sectors, legacy asset-heavy firms carry higher D/E than newer, leaner competitors even with equivalent credit quality.
