How do profit and loss (P&L) statements work?

Wondering what a Profit and Loss (P&L) statement really tells you about a business?

Well, it's one of the three key financial statements companies regularly produce, providing a clear overview of Revenues, Expenses, and Net Profit over a specific period. Often called the Income Statement, the P&L is crucial for public companies to meet legal reporting requirements.

It's not just a formal document; market analysts, investors, and creditors closely examine P&L statements to assess a company's financial performance, including its revenue generation and expense management, ultimately reflecting its profitability.

This blog introduces you to the vital components and significance of P&L statements in the business world.


A profit and loss statement is a financial document that provides an overview of your business’s total income and total expenses in a set period.

Before we delve into the intriguing world of Profit and Loss (P&L) statements, let's take a moment to grasp some essential concepts you should be familiar with

  • Foundation of P&L Statements: They can be prepared using either Cash-Based Accounting or Accrual-Based Accounting, each offering a different financial perspective.
  • The Trio of Financial Reporting: Public companies are required to issue three key financial statements quarterly and annually – the P&L statement, the balance sheet, and the cash flow statement.
  • A Comprehensive Financial Picture: Together, the P&L report, balance sheet, and cash flow statement form a 'triple threat', providing an all-encompassing view of a business's financial health and performance.
  • Importance of Regular Review: Monitoring P&L statements across different accounting periods is crucial to identify trends and changes, going beyond just the surface numbers to understand the financial narrative of your business.

2. What Does a P&L Statement Show?

The P&L contains details about the company's revenue, or the total amount of income from the sale of goods or services associated with the company's primary operations. It also shows the company's business expenses, such as rent, cost of goods sold (COGS), freight, and payroll.

Expenses are deducted from revenue to provide the net income or net loss. A primary goal for any business is to achieve a net income, indicating financial health. If the net income is small compared to the revenue, it suggests the business is barely sustaining its operations, prompting a need to boost revenue or cut down costs

To calculate the net profit accurately, the P&L also factors in debts, interest payments, earnings from secondary activities or investments, and exceptional one-time costs like legal settlements.

Additionally, the statement includes vital subtotals, providing insights into aspects like long-term or short-term debt, raw material costs, overhead expenses, and tax liabilities.

The P&L Statement offers a full view of a company’s financial performance over a period, showing whether it has made a profit or incurred a loss. For accuracy in reflecting a company's profitability, accountants typically use accrual accounting. This method accounts for revenue and expenses at the time they occur, rather than when cash transactions happen.

3. Structure of the Profit and Loss Statement

The standard structure of a Profit and Loss (P&L) Statement typically includes several key components that provide a comprehensive view of a business's financial performance over a specific period.

Here's a brief overview of its structure:

  • Total Revenue: This is the total income generated from the business's primary operations. It includes income from sales of goods or services and is the starting point of the income statement.
  • Cost of Goods Sold (COGS): This represents the direct costs attributable to the production of the goods sold by a company. This includes the cost of the materials and labor directly used to create the product. It's subtracted from Total Revenue to determine Gross Profit.
  • Gross Profit: Calculated as Total Revenue minus COGS, this figure shows the profitability of the company's core business activities before considering other operating expenses. It's a key indicator of the efficiency of the core business operations.
  • Operating Expenses: These are the costs required to run the company that are not directly tied to the production of goods or services. This includes expenses like marketing, rent, utilities, administrative salaries, and depreciation. They are subtracted from Gross Profit to calculate Operating Income.
  • Operating Income: Also known as Earnings Before Interest and Taxes (EBIT), this is calculated by subtracting Operating Expenses from Gross Profit.
  • Other Income/Expenses: This includes any revenue or costs not related to the primary business activities, such as interest earned or expenses from loans.
  • Net Income/Profit: The final line of the P&L Statement, is calculated by subtracting all expenses (including taxes) from total revenues. It represents the company's profit or loss during the reporting period.

This structure allows businesses and stakeholders to assess the financial health of the company, analyze its operational efficiency, and make informed decisions.

4. How to Prepare a Profit and Loss (P&L) Statement

The single-step method

Are you a small business or operating in a service-based industry? Then this might be your method of choice. It calculates net income by subtracting expenses and losses from revenues and gains.

It gets its name from the fact that it uses a single subtotal for all revenue line items and a single subtotal for expense items. You can find your net gain or loss at the bottom of the statement, which is known as the “bottom line” in accounting.

Sales Revenue 150,000
Service Revenue 50,000
Total Revenues 200,000
Cost of Goods Sold 70,000
Operating Expenses 30,000
Administrative Expenses 20,000
Total Expenses 120,000
Net Income 80,000

5. Do Small Businesses Need Profit and Loss Statements?

Absolutely. Profit and loss statements are not only crucial but occasionally mandatory. Publicly traded companies, for instance, are required to produce them. Small businesses seeking loans may also find that lenders request these statements. Additionally, they are often needed for tax purposes.

Now, focusing on their significance, P&L statements provide essential insights, such as the ones we'll explore below.

Where profit is coming from

If your business deals in a range of products or services, a Profit and Loss (P&L) statement allows you to categorize them into distinct line items. This categorization is invaluable in pinpointing which aspects of your business are yielding the most profit and which ones are underperforming. Understanding these distinctions is crucial for strategic business decision-making.

Evaluating Cost Management:

A Profit and Loss (P&L) statement acts as an objective tool to review your business's financial history. By comparing past quarters or years, you can conduct a thorough analysis of your financial performance. This comparison helps you assess if your expenses are rising at an expected rate, staying consistent, or perhaps increasing disproportionately compared to revenue growth.

For example, if your revenue grew by 10% over the previous year but your material costs soared by 40%, it's important to investigate the reasons and implications of such a change.

Assessing Profitability of Operations:

The true highlight of a P&L statement is its ability to show whether your business operations are profitable. The bottom line of the statement, quite literally at the end, reveals if your business is making a profit or incurring a loss. This clear indicator is essential for understanding the overall financial health of your business and guiding future financial strategies.
