If you have ever opened your startup's income statement and felt your eyes glaze over, this guide is for you. Learning how to read a P&L statement is one of the highest-leverage skills a founder can build, because the profit and loss statement, also called the income statement or, in Indian statutory filings, the Statement of Profit and Loss, is the single clearest scoreboard of whether your business model actually works. It sums up everything your company earned and spent over a period, whether a month, a quarter, or a financial year, and answers one blunt question: did we make a profit or a loss?
What a P&L statement is, and why it is not optional
At its simplest, a P&L has three parts. Revenue, the top line, is the money you earned from customers. Costs are everything you spent to earn it and to run the company. Profit, the bottom line, is what is left after you subtract costs from revenue. When costs exceed revenue, that bottom line is a loss, which is common and often deliberate in the early years.
In India this is not just a management tool, it is a legal document. Under the Companies Act 2013, every company registered with the Ministry of Corporate Affairs must present its financials in the format prescribed by Schedule III. Division I of that schedule applies to companies on the older Accounting Standards, and Division II to companies on Indian Accounting Standards, or Ind AS, while banks, insurers, and electricity companies follow separate formats. You file this statement once a year, but you should never wait a year to read it. The founders who stay in control read their P&L every single month.
How to read a P&L statement from top line to bottom line
Schedule III lays the statement out in a fixed order. Here is what each line means in plain language, reading from the top down.
- Revenue from operations: the money from your core business, such as product sales, subscriptions, or service fees. Note that this is shown net of GST, because the GST you collect belongs to the government and is never your income.
- Other income: money that is not your main business working, such as interest on bank deposits or foreign-exchange gains. Keep it mentally separate, because a business that only looks profitable thanks to interest on its funding is not really profitable.
- Total income: revenue from operations plus other income.
- Cost of materials, purchases of stock-in-trade, and changes in inventories: the direct cost of the goods you sold. A software company has little here, a product company a lot.
- Employee benefits expense: salaries, provident fund, ESI, gratuity, and bonuses.
- Finance costs: interest you pay on loans and other borrowings.
- Depreciation and amortisation: the spreading of the cost of assets, such as laptops, equipment, or capitalised software, over their useful life. It is a real expense, but not a cash outflow this month.
- Other expenses: rent, marketing, cloud software, travel, professional fees, and everything else it takes to run the business.
- Profit before tax: total income minus all of the expenses above.
- Tax expense: current and deferred tax.
- Profit for the period: the true bottom line, what the whole business made or lost after everything.
One practical thing to know: Schedule III does not print a gross profit line. You calculate it yourself, and it is one of the most important numbers on the page, so let us look at the split that produces it.
COGS versus operating expenses: the split that decides your margin
Costs fall into two buckets, and telling them apart is the heart of reading a P&L well.
Cost of goods sold, or COGS, is the direct cost of delivering each unit of what you sell. It rises and falls with volume. For a SaaS company this is cloud hosting, payment-gateway fees, and the support tied directly to usage. For a D2C brand it is raw materials, manufacturing, packaging, and inbound freight. For a services firm it is the salaries of the people whose time is billed to clients.
Operating expenses, or opex, is the cost of running the company whether or not you make a single extra sale: founder and admin salaries, office rent, brand marketing, software tools, and legal and accounting fees.
This split matters because it produces your two most telling profit numbers. Gross profit is revenue minus COGS, and it shows how profitable your core product is on its own. Net profit is gross profit minus all operating expenses, and it shows whether the entire business makes money. Between them sits EBITDA, earnings before interest, taxes, depreciation, and amortisation, which founders and investors watch because it strips out financing choices and accounting entries to show how the core operation is really performing.
Gross-margin benchmarks by business model
Gross margin is gross profit divided by revenue, written as a percentage, and it is the number that reveals whether your business model can ever pay for itself. What counts as healthy depends heavily on what you sell.
- SaaS and software: 70 percent and above. A healthy SaaS company runs a gross margin of roughly 70 to 80 percent, and packaged software can reach around 85 percent. Because each additional customer costs very little to serve, software is the highest-margin model here, which is exactly why investors love it.
- Ecommerce and D2C: lower, and more demanding. Broad ecommerce gross margins run roughly 30 to 50 percent, while consumer, beauty, and personal-care brands often reach 50 to 70 percent. In the Indian D2C market the practical rule is that you generally need a gross margin above 60 percent to leave enough room for customer acquisition, fulfilment, and returns, all of which sit below the gross-profit line and quietly eat into what looks like a healthy margin.
- Services: it depends on how specialised you are. Consulting and advisory work typically runs a 40 to 60 percent gross margin, while commodity IT services are thinner at around 25 to 35 percent, and highly specialised services can reach 50 to 70 percent.
One caution: these are broad benchmarks drawn largely from mature and public companies, and private, early-stage firms usually run several points below them. The absolute number matters far less than your own trend, and a rising gross margin as you grow is one of the strongest signs that your model is working.
A worked example in rupees
Imagine a small Indian SaaS startup in a single month.
- Revenue from operations: ₹25,00,000
- COGS, being cloud hosting, payment-gateway fees, and support: ₹5,00,000
- Gross profit: ₹20,00,000, which is an 80 percent gross margin
- Operating expenses: salaries ₹14,00,000, marketing ₹5,00,000, rent, software, and other ₹3,00,000, for a total of ₹22,00,000
- Net result: a loss of ₹2,00,000
On the surface this is a loss, but read it properly and it is encouraging. The 80 percent gross margin means the product itself is highly profitable, and the loss is a deliberate choice to spend on salaries and marketing to grow. Now change one number. Had the same startup run a 30 percent gross margin, gross profit would be only ₹7,50,000, and the same ₹22,00,000 of operating expenses would produce a loss of ₹14,50,000 with no obvious way out. Same revenue, same spending, completely different future. That is why gross margin, not the headline loss, is the number that tells you whether growth spending can ever turn into profit.
The three numbers to watch every month
You do not need to memorise the whole statement. Track three numbers, one from each part of the P&L, and review them monthly.
- Revenue growth, the top line. Is revenue from operations climbing month on month, and how fast? This is the clearest sign of demand for what you sell.
- Gross margin, the middle. Is your gross margin holding or improving as you scale? A falling gross margin means growth is getting more expensive to deliver, which is a warning worth acting on early.
- Net profit or monthly burn, the bottom line. Are you making money or losing it, and if you are losing it, how fast? Losing ₹2,00,000 a month with ₹1 crore in the bank is a runway you can plan around. Watch operating expenses against revenue too: if opex is growing faster than revenue, you are scaling costs faster than the business.
Read the trend, not the snapshot
The biggest mistake founders make with a P&L is treating a single month as a verdict. One good month can be luck or a large one-off order. The signal lives in the trend. Line up six to twelve months of P&Ls side by side and read across the rows. Is gross margin rising as revenue grows? Are operating expenses growing more slowly than revenue? Is the monthly loss shrinking steadily toward breakeven? Comparing each month against the same month last year also strips out the seasonality that distorts businesses like retail and travel.
A profitable snapshot can flatter a failing business, and a loss-making snapshot can hide a healthy one that is investing to grow. The trend cannot hide either. Read your P&L every month, watch those three numbers move over time, and you will always know whether your business model is genuinely working, long before the annual filing tells the rest of the world.
