EBITDA strips away the effects of financing (interest), accounting (depreciation/amortisation), and tax structures to show a company's core operating profitability. It is the closest approximation to how much cash a business generates from its operations — making it the most widely used metric for comparing businesses across sectors and capital structures.
What Is EBITDA?
EBITDA = Earnings Before Interest, Taxes, Depreciation and Amortisation
Breaking it down:
- Earnings: The company's profit at the starting point
- Before Interest: Adds back interest expense — so debt levels don't affect the comparison
- Before Taxes: Adds back tax — so tax structures don't affect comparison
- Before Depreciation: Adds back depreciation on physical assets (plant, machinery)
- Before Amortisation: Adds back amortisation of intangible assets (patents, licences)
The result is a measure of operating profitability that is comparable across companies regardless of their debt levels, tax situations, or accounting choices.
How to Calculate EBITDA
Two approaches:
- Top-down: EBITDA = Revenue − Operating Expenses (excluding D&A, interest, tax)
- Bottom-up: EBITDA = Net Profit + Interest Expense + Tax + Depreciation + Amortisation
Example — Tata Steel quarterly results:
Revenue: ₹55,000 crore. Operating expenses: ₹47,000 crore. Operating Profit (EBIT): ₹8,000 crore. Depreciation: ₹2,500 crore. EBITDA = ₹8,000 + ₹2,500 = ₹10,500 crore. EBITDA Margin = ₹10,500 ÷ ₹55,000 = 19.1%.
EBITDA Margin — The Profitability Benchmark
EBITDA Margin = EBITDA ÷ Revenue × 100. This is the most important use of EBITDA for Indian traders:
| Sector | Typical EBITDA Margin | What It Means |
|---|---|---|
| IT Services (TCS, Infosys) | 22–28% | Asset-light, high margin business |
| FMCG (HUL, Nestle) | 18–25% | Strong brand premium |
| Pharmaceuticals | 18–25% | High R&D spend but strong margins |
| Steel/Metals | 12–20% | Cyclical, commodity-driven |
| Airlines | 8–15% | High fixed costs, thin margins |
| Retail | 5–10% | Volume-driven, low margins |
EV/EBITDA — The Valuation Multiple
Enterprise Value (EV) = Market Cap + Total Debt − Cash. EV/EBITDA = EV ÷ EBITDA. This is the preferred valuation multiple for capital-intensive industries (steel, telecom, manufacturing) where P/E can be distorted by depreciation and debt levels.
- EV/EBITDA below 8 = potentially undervalued (for most Indian sectors)
- EV/EBITDA above 20 = premium valuation — requires high growth justification
- Compare within sector, not across sectors
Open any quarterly results announcement from a Nifty 50 company on NSE (Results → Earnings). Look for the EBITDA line and EBITDA margin. Is it improving or declining quarter-over-quarter? A company with improving EBITDA margins is becoming more profitable — a positive sign. Read next: What Is Delivery vs Intraday Trading in India?
