How to Read a Profit and Loss Statement: Why I Don't Read It as Cash

The Structure: Top to Bottom

A standard P&L flows from the top (revenue) downward through a series of deductions to the bottom line (net profit).

Revenue (also called Turnover or Sales)

This is the total value of goods sold or services delivered during the period, not cash received. If you raised invoices worth ₹15 lakh in April, April's revenue is ₹15 lakh, even if payment arrives in June.

For GST-registered businesses, revenue in the P&L is usually shown exclusive of GST (net of GST collected), since GST is a pass-through: collected and remitted to the government.

Revenue can be broken down further:

• By product or service line
• By customer segment
• By geography

These breakdowns matter when you're trying to see which part of the business is growing and which isn't.

Cost of Goods Sold (COGS) / Cost of Revenue

This includes only the direct costs of delivering the product or service:

For a manufacturer: raw materials consumed, direct labour, factory overhead directly tied to production.

For a service business: cost of subcontractors, project-specific expenses, direct materials used in the service.

For a retail business: the purchase cost of the goods sold.

For any business that holds stock, COGS is worked out from the stock: opening stock plus purchases (and direct costs), less closing stock. Hold on to that formula; it is the reason the closing stock figure matters so much, and I come back to it below.

What doesn't go in COGS: office rent, marketing, management salaries, admin costs. These are operating expenses (below).

Gross Profit = Revenue − COGS

Gross Profit Margin = (Gross Profit ÷ Revenue) × 100

This is one of the most important margins to track. It tells you how much value you're adding through your core business activity before overhead.

A software services business might have an 80%+ gross margin (low direct costs relative to fees). A manufacturing business might have 30–40%. A retail business might be at 20–30%.

Low gross margin is a structural problem: it means the cost of delivering your product or service is eating most of your revenue before you've even paid for your office or marketing. High gross margin gives you room to invest in growth.

Operating Expenses (OpEx)

These are the costs of running the business, beyond the direct cost of delivery:

• Staff costs: salaries, EPF/ESI contributions, ESOP costs, recruitment costs
• Rent and utilities: office or manufacturing space, electricity, internet
• Marketing and sales: advertising, sales commissions, promotions, events
• Technology: software subscriptions, cloud hosting, IT support
• Professional fees: CA, lawyer and consultant fees
• Depreciation: a non-cash charge for the wear of fixed assets (equipment, computers, vehicles)
• General and administrative: stationery, travel, insurance premiums, bank charges

The line between COGS and OpEx matters for reading gross margin correctly. As a business grows, it's worth getting these categorised cleanly.

EBITDA (Earnings Before Interest, Tax, Depreciation, Amortisation)

EBITDA = Gross Profit − Operating Expenses (excluding depreciation and interest)

This is a rough proxy for operating cash generation: what the business produces from operations before paying lenders and the government. It is widely used in business valuation and by lenders.

EBITDA margin = EBITDA ÷ Revenue

A healthy EBITDA margin varies widely by industry. For a services business, 20–35% is solid; a SaaS company can run higher; for a trading business, 5–8% is normal.

Operating Profit (EBIT)

EBIT = EBITDA − Depreciation

Depreciation is a non-cash expense that accounts for the wearing out of capital assets. A ₹3 lakh laptop used for 3 years has ₹1 lakh of depreciation per year, which appears as an expense on the P&L even though no cash left the bank for it in that year.

EBIT shows the business's profitability from operations after allowing for the replacement cost of its assets.

Finance Costs (Interest)

Interest paid on all business loans: term loans, overdrafts, working capital credit. A business carrying a lot of debt shows significant finance costs that drag down net profit even when EBITDA is healthy.

This is why an owner can wonder "I have good business, why is profit so low?": interest is eating a large part of operating profit. I have watched this play out from the inside, in a business that was sound in its operations on paper while the interest line alone could swallow most of what those operations generated. EBITDA tells one story; profit after finance costs tells a more honest one.

On a cash credit, part of this line is in the owner's hands: the finance cost falls with every day the drawn balance is kept low. At our mill draws are kept to what the week's payments require, and collections go against the balance as they come in. The finance cost on the P&L is, in part, a record of how the account was run.

Profit Before Tax (PBT)

EBIT − Finance Costs = PBT

This is the taxable profit, before corporate or business income tax is applied.

Tax

For a Pvt Ltd company: corporate tax (25% for domestic companies with turnover under ₹400 crore; actual rates depend on the option chosen, deductions and surcharges).

For a proprietorship or partnership: the owner's income tax at their individual slab rates on business profit.

Net Profit (PAT: Profit After Tax)

The bottom line. This is what the business actually earned for the owner(s) after all costs, depreciation, interest, and tax.

Net Profit Margin = (Net Profit ÷ Revenue) × 100

For a small service business, a 15–25% net margin is healthy. For a trading business, 3–5% might be excellent. Context matters.

Five Numbers to Track Every Month

1. Revenue: is it growing? How does this month compare with the same month last year?

2. Gross Profit Margin: is it stable? Compression can mean costs went up, pricing softened, or the mix shifted toward lower-margin work.

3. Largest operating expense line: what is the biggest OpEx item, and is it growing faster than revenue? Salaries usually grow more slowly than revenue in a scaling business; if they're growing faster, that's a flag.

4. EBITDA Margin: is operating performance improving over time?

5. Finance Cost as % of Revenue: If your loan interest payments are above 5–7% of revenue, debt is significantly constraining your profitability.

Reading the P&L for Decisions

Should I hire? Look at gross profit and EBITDA. If gross profit is growing but EBITDA isn't, overhead is growing too fast. If both are healthy, adding capacity to serve more revenue makes sense.

Can I afford this expense? Compare the new expense with EBITDA. If a ₹1.5 lakh annual software subscription would be 15% of your current EBITDA, that's a significant cost relative to current profitability. If it's 2%, it's easy to absorb.

Am I pricing correctly? Gross margin tells you this more than anything. If gross margin is consistently below industry norms despite good revenue, you're leaving money on the table in pricing. The break-even calculator shows how far a price change moves the volume you need.

Is this business viable? A business that shows revenue but persistent negative EBITDA over more than 12–18 months has a structural cost problem. Either revenue must grow, costs must be cut, or the business model needs to change.

The Line I Check Before I Trust the Bottom Line

In a business that holds stock, the number that decides the profit is one many owners never look at: closing stock.

Go back to the COGS formula. Opening stock plus purchases, less closing stock, is the cost charged against this period's sales. So every rupee of closing stock is a rupee of cost that has not been charged yet. Value the stock too high and the profit rises with it, on paper only. In a rice mill the stock is paddy, rice, broken rice, bran and husk, each at a different value, and the quantity in the godown changes all through the season.

That is why, before I believe a P&L for our mill, I want to know that the stock in it matches the stock in the godown. That is what checking the godown register against the stock ledger is for. Stock inflated on a bank statement is a mistake in one document; a P&L built on the same inflated figure repeats it in another. How stock is counted and valued for a bank goes deeper, and the inventory turnover calculator shows how long your stock actually sits before it becomes a sale.

Getting a Monthly P&L

If you're working with a CA, ask for a monthly P&L. Most will provide one as part of the same work they do for GST filings and compliance. At our mill the accountant's weekly visits keep the books close to date, and the separately engaged CA finalises the year's accounts.

If you use accounting software (Zoho Books, Tally Prime), the P&L is generated in 2 clicks. Review it yourself at the start of each month.

If you're doing it by hand, a Google Sheet with income and expense categories, updated monthly from your bank statement, gives you a simplified P&L that is good enough for most small business decisions.

The P&L is not a document for your CA alone. It's your business's scorecard, and reading it monthly is one of the most useful habits a business owner can build. Even so, I have run a business that looked profitable on the P&L every single month while the bank balance told a completely different story: stock had moved and invoices were raised, but the cash to fund the next cycle was not there yet. For the cash side of the same month, pair it with a view of business cash flow.

How GST Appears (and Doesn't Appear) on a P&L

One of the most common P&L errors for newly GST-registered businesses is counting GST collected as revenue:

Correct treatment: GST collected from clients is a liability, not revenue. If you invoice Rs.1,00,000 + Rs.18,000 GST, your revenue is Rs.1,00,000. The Rs.18,000 sits as a liability until it is remitted to the government through GSTR-3B.

Input Tax Credit: GST paid on business purchases is, in most cases, not an expense either. It is an asset (ITC receivable) that offsets your GST liability; the actual expense is the base price excluding GST.

Net GST impact on P&L: only the net GST, output tax minus ITC, appears on the P&L, under "taxes" or as a reconciling item. For most registered service businesses the net GST is zero (you pay out exactly what you collected minus what you reclaimed). The P&L is largely GST-neutral for regular taxpayers.

Composition scheme businesses: these pay GST out of pocket on turnover (they don't charge GST on invoices). For them, GST paid is a direct expense, typically listed under "taxes and levies" in operating expenses.

P&L for Sole Proprietors vs Companies: Key Differences

The P&L structure is similar across business forms, but some details differ:

Sole proprietorship:

• The proprietor's drawings (the owner's monthly transfer to a personal account) are not an expense on the P&L; they are an appropriation of profit
• The proprietor's own "salary" does not reduce profit; all profit is the proprietor's income
• Income tax is paid at individual rates on net profit and, in most cases, does not appear as a P&L expense
• Advance tax payments appear as assets (advance tax paid) in the balance sheet until the year closes

LLP:

• Partner remuneration (salary and interest on capital, within Section 40(b) limits) is a deductible expense on the LLP's P&L, reducing taxable income
• The LLP pays tax at a 30% flat rate on its profits; income tax is a P&L expense
• Partners' profit shares after remuneration are exempt in their hands

Private Limited Company:

• Director salaries (including working directors) are operating expenses on the P&L
• Corporate tax (25% for most small companies) is a P&L expense
• Dividends paid to shareholders are an appropriation of profit, not a P&L expense

Knowing which of these structures a P&L belongs to changes how you read several lines, particularly labour cost and tax. How owners actually take money out under each structure is covered in how to pay yourself as a business owner.

P&L Benchmarks for Indian Service Businesses

Approximate industry benchmarks help you judge whether your margins are competitive or concerning:

Solo consulting/freelance (single professional):

• Gross margin: 85-95% (almost all revenue falls through to gross profit)
• Operating expenses: 10-25% of revenue
• Net margin: 60-75% before income tax

Small agency (5-15 employees, B2B services):

• Gross margin: 45-65% (staff costs in COGS for the billable team)
• Operating expenses: 25-35% of revenue
• Net margin: 10-20% before tax

SaaS or technology product business:

• Gross margin: 65-80% (cloud hosting, support staff)
• Operating expenses: often exceed revenue in the growth phase
• Net margin: negative early, 20-35% when scaled

Trading business:

• Gross margin: 10-25% (purchase cost of goods is dominant)
• Operating expenses: 5-10% of revenue
• Net margin: 3-8%

Manufacturing SME:

• Gross margin: 25-40% (material + direct labour)
• Operating expenses: 10-20% of revenue
• Net margin: 5-15%

Trading margins are thin by nature, which matches what I have seen first-hand in agri-commodity trading. A trading business can move a large amount of value and still leave little at the bottom line, which is why I would never judge one by its turnover, and why cash discipline down to the smallest payments matters more there than headline sales.

If your margins are consistently below industry norms, look at whether costs are too high (addressable) or pricing too low (also addressable) before assuming the benchmark is wrong.

Depreciation on the P&L: What It Means Practically

Depreciation is the most misunderstood P&L line for most small business owners. The key points:

Non-cash expense: depreciation reduces profit but is not a cash outflow. A Rs.80,000 laptop bought in April generates Rs.32,000 of depreciation expense in year one (at the 40% WDV rate for computers under the IT Act), but the cash went out in April. The Rs.32,000 of depreciation on the P&L in September doesn't mean Rs.32,000 left the bank.

Tax treatment: depreciation reduces your taxable income under regular accounting (ITR-3). Under 44ADA presumptive taxation (consolidated into Section 58 under the Income-tax Act, 2025 from 1 April 2026, at the same rate), depreciation is deemed "already accounted for" in the presumptive profit, so you cannot claim it separately.

Capital vs revenue: a Rs.5,000 keyboard is typically expensed immediately (revenue expenditure). A Rs.80,000 laptop is capitalised and depreciated (capital expenditure). The law sets no fixed threshold for small businesses, but Rs.5,000-10,000 is a common practical cutoff. Consistent treatment from year to year is what matters for both accuracy and audit-readiness.

For your specific tax treatment or structure, run it past your CA. This guide is meant to help you read the numbers, not to replace their sign-off.
