Profit and Loss Statement Explained for Business Owners
A business can report growing sales and still struggle with cash or shrinking margins. A profit and loss statement helps explain whether the problem lies in pricing, purchase costs, operating expenses or delayed collections.
This guide is for Indian business owners who have been operating for one to three years and want to understand their numbers without complex accounting language.
Quick summary
- A P&L shows the income, costs, and profit or loss of a business for a selected period.
- Gross profit shows what remains after direct costs. Operating profit shows what remains after regular business expenses.
- Profit before tax reflects other income after deducting finance costs.
- Profit and bank balance are different because credit sales, stock purchases, loan repayments and asset purchases affect them differently.
- GST collected from customers is generally not revenue. Recoverable GST on purchases is normally recorded separately from expenses.
- Reviewing the report every month helps you spot falling margins, rising costs and slow collections before they become larger problems.
What a P&L Shows
A P&L statement summarises the income earned and expenses incurred during a month, quarter or financial year. It answers a simple question: did the business earn more than it spent during that period?
The same document may also be called an income statement, profit and loss account or profit loss report. The name may differ, but the purpose is broadly the same.
P&L vs Balance Sheet
A P&L covers activity between two dates. For example, a monthly report may cover 1 July to 31 July. A balance sheet shows the position on one date. It lists what the business owns, what it owes and the owner’s or shareholders’ interest in the business.
Cash and Mercantile Accounting
The timing of income and expenses depends on the accounting method followed by the business.
| Method | When Income Is Recorded | When Expenses Are Recorded |
|---|---|---|
| Cash method | When money is received | When money is paid |
| Mercantile or accrual method | When income is earned | When the expense is incurred |

When Expenses Are Recorded
The Income-tax Act, 2025 has applied since 1 April 2026. Section 276 permits business income to be computed using either the cash or mercantile method, provided the chosen method is followed regularly.
Companies must keep their books on an accrual basis under Section 128 of the Companies Act, 2013. An LLP may keep its books on a cash or accrual basis under Section 34 of the Limited Liability Partnership Act, 2008.
The example below follows the mercantile method. A business using the cash method may record some transactions in a different period.

The example stops at profit before tax because the way income tax appears in the accounts depends on the legal structure of the business.
Net Revenue
Deepak Traders recorded gross sales of ₹42 lakh, excluding GST. After deducting returns and discounts of ₹1.2 lakh, its net revenue was:
₹42,00,000 - ₹1,20,000 = ₹40,80,000
GST collected from customers is generally recorded as a tax liability, not as business revenue. GST paid on purchases that is eligible for input tax credit is normally recorded separately, while blocked or non-recoverable GST may form part of the related cost or expense.
Cost of Goods Sold
Cost of goods sold means the cost of the inventory that was actually sold during the period. It is not always the same as purchases made during that period. For a trading business, a simplified calculation is:
Opening stock + purchases + direct inward costs - closing stock
₹8,00,000 + ₹29,70,000 + ₹30,000 - ₹6,50,000 = ₹31,50,000
Inventory cost may include the purchase price, freight inward, non-recoverable taxes and other costs needed to bring the goods to their present location and condition. Recoverable taxes, trade discounts and rebates are generally excluded.
Gross Profit
Gross profit shows what remains after deducting the direct cost of goods sold from net revenue.
₹40,80,000 - ₹31,50,000 = ₹9,30,000
The gross margin is:
₹9,30,000 ÷ ₹40,80,000 × 100 = 22.8%
Gross margin helps the owner judge pricing, purchase costs, discounts and product mix. It is usually more useful to compare this percentage with the business’s own previous periods than with a general industry benchmark.
Operating Profit
Operating profit is calculated after deducting regular operating expenses such as salaries, rent, delivery costs, marketing, administration and depreciation.
Deepak Traders earned an operating profit of ₹1.4 lakh, equal to 3.4% of net revenue. This shows how much the normal operations produced before finance costs and income tax.
Profit Before Tax
After adding other income and deducting loan interest, Deepak Traders reported a profit before tax of ₹1.1 lakh.
The profit-before-tax margin is:
₹1,10,000 ÷ ₹40,80,000 × 100 = 2.7%
Profit before tax shows the result after operating expenses, other income and finance costs, but before income tax.
Why Profit and Bank Balance Are Different
Profit measures income and expenses according to the accounting method used. A bank balance shows the money currently available in one account.
| Transaction | Effect on Profit | Effect on Cash |
|---|---|---|
| Goods sold on credit | Revenue and profit may increase now | Cash arrives later |
| Stock purchased but not sold | Usually remains inventory | Cash reduces now |
| Loan principal repaid | Does not normally reduce profit | Cash reduces |
| Loan interest recorded | Reduces profit | Cash reduces when paid |
| Depreciation recorded | Reduces profit | No current cash payment |
| Customer advance received | Usually not revenue until it is earned | Cash increases now |
| Equipment purchased | Normally recorded as an asset when it meets the business’s capitalisation policy | Cash reduces now |

Note: Profit is not available cash. Read the P&L together with receivables, payables, stock and cash-flow reports. A profitable business can still face a shortage if customer payments are late or too much money is tied up in stock.
Common Mistakes That Distort the Report
| Mistake | Why It Creates a Problem | Better Treatment |
|---|---|---|
| Treating all purchases as cost of sales | Unsold goods may be charged as an expense too early | Adjust purchases for opening and closing stock |
| Recording personal drawings as an expense | It understates business profit | Record owner withdrawals separately from business costs |
| Ignoring expenses already incurred | A month may appear more profitable than it was | Under the mercantile method, record expenses in the period they relate to |
| Putting large amounts under “miscellaneous” | The owner cannot see where money is going | Use clear categories for material costs |
| Keeping damaged stock at full cost | Closing stock and profit may be overstated | Review whether the stock needs to be written down |

Under ICAI’s Accounting Standard 2, inventory is generally valued at the lower of cost and net realisable value. Net realisable value means the expected selling price after deducting the costs still needed to complete and sell the goods.
How to Review Your P&L
A long checklist is not needed. Four measures, reviewed at the right frequency, usually provide a clear starting point.
| Review Area | What to Compare | What It Helps You Understand |
|---|---|---|
| Net revenue | Previous month, same period last year and sales target | Whether sales growth is real after returns and discounts |
| Gross margin | Previous months and major product categories | Whether pricing, buying costs or product mix has changed |
| Operating expenses | Revenue and the business budget | Whether overheads are growing faster than the business |
| Profit before tax and collections | Customer receipts, overdue invoices and supplier dues | Whether reported profit is turning into usable cash |

Suppose Deepak Traders earned a 24% gross margin in the previous quarter and 22.8% in the current quarter. The fall of 1.2 percentage points on ₹40.8 lakh of revenue represents about ₹48,960 of lower gross profit.
That change should prompt the owner to check supplier prices, discounts, stock records and product mix.
Review the report monthly to find issues early. Use quarterly comparisons to reduce the effect of unusual transactions and seasonality. Use the annual report for final accounts, tax work and finance applications.
Keeping invoices, purchases, expenses and receipts in one system makes this review easier. With mazu, businesses can record these transactions and use dashboards and business reports to track sales, collections, expenses and performance.
Why Accounting Profit and Taxable Income May Differ
The profit shown in the accounts is not always the same as taxable business income. Tax law may allow or delay certain deductions even when the expense has been recorded correctly in the books. One important example is a delayed payment to a qualifying micro or small enterprise.
Section 37(2)(g) of the Income-tax Act, 2025 links the deduction to the payment period specified in Section 15 of the Micro, Small and Medium Enterprises Development Act, 2006. A written payment period cannot exceed 45 days from acceptance or deemed acceptance of the goods or services. Without a written agreement, payment is generally due within 15 days. If payment is delayed beyond the permitted period, the deduction may be allowed only when the amount is actually paid.
This changes the tax calculation, not the original accounting entry. The expense may remain in the P&L even when its deduction is deferred for tax purposes.
Conclusion
A profit and loss statement is most useful when it is read every month, not only when accounts are finalised at year-end.
Start by checking whether revenue excludes GST, inventory is valued correctly, personal withdrawals are kept separate, and expenses are recorded in the right period. Then compare gross margin, operating costs and customer collections over time.
No single percentage can tell you whether the business is healthy. The direction of the numbers, and the reason behind each change, provides the better answer.
