Lesson 13: The Income Statement

Lesson 13 of 33 · 39%

What is the income statement?

The income statement (also called the Profit & Loss statement, or P&L) tells you whether the business made money over a period — a month, a quarter, a year. It starts with revenue, subtracts costs in a specific order, and ends with net income (the “bottom line”). Unlike the balance sheet (a snapshot), the income statement covers a period.

INCOME STATEMENT — Waterfall Revenue 100,000 COGS (40,000) Gross Profit 60,000 Opex (25,000) Op. Income 35,000 Net Income 26,000 After tax (assumed 25%) on operating income of ₹35,000.
Each bar is a step in the income statement waterfall. Subtract red (costs) from blue (totals) to get the next milestone.

The standard structure

LineWhat it is
Revenue (Sales)Money from selling goods or services.
− Cost of Goods Sold (COGS)Direct cost of what you sold — raw materials, direct labour, freight-in.
= Gross ProfitWhat’s left to cover everything else.
− Operating ExpensesRent, salaries, marketing, utilities, depreciation, R&D.
= Operating Income (EBIT)Profit from running the core business.
+ Other income / − Other expensesInterest earned, foreign-exchange gains, etc.
− Interest ExpenseCost of debt financing.
= Pre-tax Income (EBT)
− Income Tax ExpenseCorporate tax.
= Net IncomeThe bottom line. Flows into Retained Earnings on the balance sheet.

A real worked example

Café Latte Pvt. Ltd. — Income Statement for FY2026:

LineAmount (₹)
Revenue100,000
Less: COGS (coffee beans, milk, packaging)(40,000)
Gross Profit60,000
Less: Rent(12,000)
Less: Salaries(8,000)
Less: Utilities & misc.(5,000)
Operating Income (EBIT)35,000
Less: Interest on loan(5,000)
Less: Tax @ 25%(7,500)
Net Income22,500

So the café earned a 22.5% net margin — for every ₹100 of revenue, ₹22.50 ended up as profit.

Single-step vs. multi-step

Single-step format: sums all revenue, sums all expenses, subtracts. Simple and used by small service businesses.

Multi-step format: the one shown above. Separates COGS from operating expenses and shows gross profit, operating income, and net income as separate subtotals. Required for listed companies and almost always more useful for analysis — it tells you where the money is going.

Key margins to understand

  • Gross margin = Gross profit ÷ Revenue. Tells you how efficient production is. SaaS businesses target 70%+; retailers might run at 25-35%.
  • Operating margin = Operating income ÷ Revenue. How well the business is run.
  • Net margin = Net income ÷ Revenue. After everything, what’s left.
Why “income statement” and not “cash statement”
The income statement uses accrual accounting: revenue is recognised when earned (not when cash is received), expenses when incurred (not when cash is paid). That’s why a business can show ₹22,500 of net income but have less cash in the bank — covered in Lesson 8 (Cash Flow Statement).

When is revenue recognised?

Under both US GAAP (ASC 606) and Ind AS 115, revenue is recognised when the seller has transferred control of a good or service to the customer — typically at delivery (goods) or as the service is performed. Receiving cash in advance doesn’t qualify; that’s a liability (Unearned Revenue) until the service is delivered.

Pitfall
Don’t confuse revenue with collections and profit with cash. A SaaS startup can have ₹50 crore of ARR (revenue) and still be cash-flow negative because customers pay annually but the company spends monthly on payroll.

Practice

Compute net income

A consulting firm: Revenue ₹40,00,000; Consultant salaries ₹18,00,000; Office rent ₹3,00,000; Travel ₹2,50,000; Marketing ₹1,50,000; Interest expense ₹50,000; Tax rate 25%.

Answer: Operating expenses = 18 + 3 + 2.5 + 1.5 = ₹25,00,000. Operating income = 40 − 25 = ₹15,00,000. Pre-tax = 15 − 0.5 = ₹14,50,000. Tax = ₹3,62,500. Net income = ₹10,87,500. Net margin ≈ 27%.

Lesson recap

  • The income statement reports profit over a period.
  • Order: Revenue → COGS → Gross profit → Opex → Operating income → Interest & tax → Net income.
  • Multi-step format separates direct costs from operating costs.
  • Accrual basis: revenue when earned, expense when incurred — not cash timing.

Practical Indian Application

The Statement of Profit and Loss — popularly called the Income Statement — measures a company’s financial performance over a period (usually a year or a quarter). Under Schedule III of the Companies Act 2013, an Indian company must show Revenue from Operations, Other Income, Cost of Materials Consumed, Changes in Inventory, Employee Benefit Expenses, Finance Costs, Depreciation and Amortisation, Other Expenses, Profit Before Tax, Tax Expense, and Profit After Tax — each as a separate line item. The cascade lets a reader pinpoint exactly where margins were earned or lost. Listed companies present this statement under SEBI’s LODR for every quarter (within 45 days) and the full year (within 60 days). Auditors examine each line for completeness, classification and cut-off, while management uses it to communicate the company story to analysts.

Worked Example (in Rupees)

TCS Limited (illustrative figures) reports FY26: Revenue from Operations ₹2,50,000 crore, Other Income ₹3,500 crore, total Income ₹2,53,500 crore. Employee Benefit Expenses ₹1,40,000 crore, Other Expenses ₹40,000 crore, Finance Costs ₹500 crore, Depreciation ₹4,500 crore — total expenses ₹1,85,000 crore. Profit Before Tax ₹68,500 crore. Tax Expense ₹17,000 crore. Profit After Tax ₹51,500 crore. Earnings Per Share at face value ₹1: ₹140. This single statement tells an analyst that TCS converted roughly 21% of revenue into PAT, that employee costs were 56% of revenue, and that the company is virtually debt-free (finance cost is negligible).

Frequently Asked Questions

What is the difference between Revenue from Operations and Other Income?
Revenue from Operations is the core business — for TCS, IT services billed to clients. Other Income includes interest on FDs, dividend income, gain on sale of investments — incidental to operations.

Is depreciation a cash outflow?
No. Depreciation is a non-cash expense that spreads the cost of fixed assets over their useful life. The actual cash outflow happened when the asset was purchased.

How is the P&L different for a manufacturing vs services company?
Manufacturing P&Ls include Cost of Materials Consumed and Changes in Inventories; services P&Ls usually do not. Both follow Schedule III but with industry-specific line emphasis.

Where does GST appear in the Income Statement?
It does not — GST is collected on behalf of the government and shown as a liability. Revenue is reported net of GST in the P&L.

Reconciliation Discipline & Common Audit Findings

For Indian listed companies, the Income Statement must reconcile to three external systems: (1) GSTR-1 for revenue, (2) Form 26AS for TDS receivable, and (3) the bank statement for cash receipts. Auditors run a ‘sample of revenue’ test — picking 25-50 invoices and tracing them through the books, GST returns and bank receipts. Discrepancies of even ₹1 lakh in revenue can attract scrutiny notices under Section 143(2) of the Income-tax Act.

Common findings: (a) Revenue recognised but invoice missing — needs immediate documentation. (b) GST on advance receipts not deposited — TDS audit qualification. (c) Foreign exchange gains/losses not segregated — restatement required. (d) Inventory write-down posted to wrong head — reclassification needed. (e) ESOP expense not amortised over vesting period — material disclosure failure.

Self-test: Reliance Retail reports ₹2,00,000 crore revenue. Match this against the same year’s GSTR-9 net taxable supplies plus exempt supplies plus interstate transfers. The variance must reconcile through Form GSTR-9C. Any unreconciled item is a potential tax exposure.
