How to Read an Income Statement (P&L) Using TCS FY2024
The Income Statement is one of the fastest ways to understand how a company earns, spends, and reaches its final profit or loss. In interviews, it matters because it shows whether you can move from accounting line items to business performance, not just recite definitions. Using TCS FY2024, the P&L can be read as a top-to-bottom waterfall from Revenue at the top to Net Profit at the bottom.
- The Income Statement, also called P&L - Profit & Loss Account, reports a company's financial performance over a period, such as a quarter or year.
- It answers: How much did the company earn and spend? What is the net profit/loss?
- It flows from Revenue at the top to Net Profit at the bottom - hence called a "waterfall" statement.
- In the TCS FY2024 example, Revenue from Operations was ₹2,40,893 Cr and PAT, or Net Profit, was ₹45,908 Cr.
- Key margin analysis includes Gross Margin, EBITDA Margin, EBIT Margin, and PAT Margin.
- For TCS: the 25% EBITDA margin and 19% PAT margin are among the best in global IT, reflecting the asset-light, high-skill nature of Indian IT services.
The P&L Waterfall: From Revenue to Net Profit
The Income Statement reports a company's financial performance over a period and follows a waterfall structure. It starts with Revenue from Operations, subtracts operating and non-operating costs, adjusts for tax, and ends at PAT - Net Profit - the bottom line that belongs to shareholders.

The Income Statement, also called P&L - Profit & Loss Account, reports a company's financial performance over a period, such as a quarter or year.
How to Read Each Line Item
Revenue from Operations is the starting point of the Income Statement. In the TCS FY2024 example, it represents total billings from IT services and products and is shown as 100.0% of revenue.
Cost of Revenue (COGS) captures direct delivery costs. For TCS, this is shown as salaries of tech staff, making it the cost directly linked to delivering services and products.
Gross Profit is Revenue - COGS and reflects delivery efficiency. In TCS FY2024, Gross Profit was ₹1,23,257 Cr, or 51.2% of Revenue.
SG&A / Overheads include Sales, G&A, and support functions overhead. These costs sit below Gross Profit and help move the waterfall toward operating earnings.
EBITDA is operating earnings before D&A. For TCS FY2024, EBITDA was ₹60,260 Cr, or 25.0% of Revenue.
Depreciation & Amortization is a non-cash charge on fixed assets and intangibles. After subtracting this, the statement reaches EBIT - Operating Profit, which shows core business earnings before financing.
Finance Costs show interest on borrowings. In the TCS FY2024 example, Finance Costs were ₹238 Cr, or 0.1% of Revenue, and the note says TCS is near debt-free.
Other Income (net) includes treasury income and forex gains. The statement then reaches PBT - Profit Before Tax, calculated as EBIT - Interest + Other Income.
Tax Expense includes current and deferred tax. After tax, the statement reaches PAT - Net Profit, the bottom line that belongs to shareholders.
Key Margin Analysis
Key margin analysis includes Gross Margin, which shows the efficiency of core business, EBITDA Margin, which shows operating efficiency before capex, EBIT Margin, which shows post-depreciation operating leverage, and PAT Margin, which shows bottom-line after all costs including financing.
For TCS: the 25% EBITDA margin and 19% PAT margin are among the best in global IT, reflecting the asset-light, high-skill nature of Indian IT services.
TCS FY2024 as a Worked Example
Read the TCS FY2024 Income Statement as a waterfall. It begins with Revenue from Operations of ₹2,40,893 Cr, then subtracts Cost of Revenue of ₹1,17,636 Cr to reach Gross Profit of ₹1,23,257 Cr.
After SG&A / Overheads, TCS reports EBITDA of ₹60,260 Cr. Depreciation & Amortization of ₹4,710 Cr brings the statement to EBIT - Operating Profit - of ₹55,550 Cr.
Finance Costs of ₹238 Cr and Other Income (net) of ₹4,653 Cr move the statement to PBT of ₹59,965 Cr. Tax Expense of ₹15,178 Cr then leads to PAT - Net Profit - of ₹45,908 Cr, or 19.1% of Revenue.
Structuring a How to Read an Income Statement (P&L) Interview Answer
"Walk me through how you would read a company's Income Statement."
Do not stop at PAT. A strong answer follows the waterfall line by line and then interprets the margins, because the same Net Profit can hide very different cost structures and operating performance.
The common mistake is treating the Income Statement as just a Revenue-to-PAT summary. That costs points because the waterfall is meant to show how Revenue becomes Gross Profit, EBITDA, EBIT, PBT, and finally PAT, with each margin revealing a different part of business performance.
Conclusion
The Income Statement is a waterfall statement that connects revenue, costs, margins, tax, and bottom-line profit. In interviews, use the TCS FY2024 example to show both structure and interpretation: move from Revenue to Net Profit, then explain what each margin says about business performance.
