What is a “profit and loss account”?

Yvonne Wicke | 02.02.2026

The most important facts in brief

Alongside the balance sheet, the income statement is the main component of the annual financial statements. It is used to determine the company’s success within a specific period (usually the financial year). All income and expenses are systematically compared. If income exceeds expenses, this results in a net profit for the year; conversely, it results in a net loss for the year. According to 242 III HGB, merchants in Germany are required by law to prepare these statements in order to create transparency about the earnings situation for the tax authorities, banks and investors.

What is the profit and loss account (P&L)?

The income statement is a fundamental instrument of commercial accounting. While the balance sheet provides an inventory of assets and capital as at the balance sheet date, the income statement is a period statement. It shows the entire business activity of a company within a defined period – usually a financial year. This income statement compares all income and expenses in the form of revenue and expenditure in order to precisely measure the company’s success.

Technically speaking, the P&L account acts as a collective and sub-account of the equity account. This means that every profit and loss transaction in double-entry bookkeeping has a direct impact on equity. At the end of a period, the balances of all profit and loss accounts are transferred to the P&L account. This is where the final comparison takes place on the debit and credit side, from which the operating result is derived.

Legal basis according to 242 III HGB

In Germany, the legal framework is set out in the German Commercial Code (HGB). In accordance with 242 III HGB, the profit and loss account, together with the balance sheet, forms the main component of the annual financial statements. These regulations primarily serve to protect creditors and provide information. Every company that is obliged to keep double-entry accounts must choose this presentation in order to make the earnings situation transparent.

The importance for merchants and investors

For business people and entrepreneurs, the P&L is far more than just a tax obligation. It is the central control element for understanding where profits come from and where costs are incurred. The content of the P&L is also crucial for external stakeholders such as investors or banks: it provides information about the profitability and future viability of the company’s performance. Without a clean P&L, there is no basis for any well-founded business decision or strategic investment planning.

Who has to prepare a P&L?
  • Corporations (GmbH, AG, UG)
  • Partnerships with commercial business operations
  • Sole traders above the statutory turnover and profit limits

Companies that are not required to keep accounts can alternatively use a revenue surplus calculation (EÜR).

Profit and loss account (P&L) – briefly explained

The income statement is a periodic statement that compares all of a company’s income and expenses within a financial year. The aim is to determine the company’s success in the form of a net profit or net loss for the year. In contrast to the balance sheet, the income statement shows the economic performance over a defined period of time.

The components of the income statement: income and expenses

In order to obtain a sound overview of the financial situation, the individual items of the profit and loss account must be precisely categorized. The profit and loss account forms the core of the accounting system, as it systematically records all operational value flows. Each component of this statement helps to provide a clear picture at the end of the financial year of whether the products sold and services provided were profitable.

Sales and other operating income

The most important source of business success is sales revenue. They form the primary income from ordinary business activities. However, not all income comes directly from the sale of core products. This is where other operating income comes into play. This includes, for example, profits from the sale of fixed assets or income from the reversal of provisions. In the HGB classification, it is crucial to separate these items clearly so as not to distort the operating profitability through one-off effects.

Personnel expenses and other operating expenses

On the opposite side are the expenses that reduce the profit. In addition to the cost of materials and personnel expenses, other operating expenses often form a very large part of the invoice. These include a wide range of cost items such as rent, travel expenses, insurance premiums and marketing expenses.

In modern profit and loss accounting, detailed recording of this data is essential. Only those who have their other operating expenses under control can achieve sustainable cost optimization. In a professionally managed T account or a digital template, these values can be called up at any time to counteract undesirable developments at an early stage.

Common errors in the income statement
  • Mixing of profit and liquidity
  • Lack of accrual accounting
  • Distortion of the result due to one-off effects
  • Insufficient differentiation of other operating expenses
  • Lack of comparability between periods

The heart of the calculation: net income and net loss for the year

The primary objective of every profit and loss statement is the final determination of the company’s success. This value provides information on whether the operating activities of a company were economically successful in the period under review or whether a loss was generated. In reporting and in the official annual financial statements, this result is shown as net income (profit) or net loss (loss).

Comparison of expenses and income

The mechanism behind this is a consistent comparison of all value flows. While only cash flows flow in the cash flow statement, all income is allocated to the corresponding expenses on an accrual basis. This is the only way to get a real picture of the earnings situation. In practice, this means that even if an invoice has not yet been paid, the revenue is already included in the current income statement, provided the service has been rendered.

Income statement: from gross profit to net profit

Modern profit and loss accounting is usually carried out in the graduated form. This presentation makes it possible to analyze intermediate steps. You start with turnover, deduct the direct costs to obtain the gross profit and work your way through the operating result (EBIT) to the final net profit for the year. Only after deducting all taxes is it clear how much equity has actually accrued to the company.

In order to make this complex data tangible, it is essential for controlling to monitor the quality of this information.

Step-by-step guide: How to create a P&L statement

Systematic preparation within the accounting system is required in order to create a correct P&L. The process does not just begin at the end of the year, but is the result of the continuous recording of all business transactions. The aim is to present a complete comparison at the end of the period, which is a mandatory part of the annual financial statements.

Recognition of business activities in the current financial year

Every sale of products, every service provided and every invoice received must be recorded promptly. In double-entry bookkeeping, these transactions are documented in profit and loss accounts (expense accounts and income accounts). The distinction is important here: only income and expenses that belong economically to the current financial year may be included in the calculation.

Closing the income statement accounts via the collective account

The actual closing takes place at the end of the period. The balances of all income statement accounts are transferred to the income statement account. This acts as a collective sub-account of equity.

  1. Debit side: All expenses (e.g. materials, personnel, other operating expenses) are brought together here.
  2. Credit side: This is where all income (e.g. sales, other operating income) ends up. The balance resulting from this calculation is the net profit or loss for the year.
Why the P&L is indispensable for controlling
  • Transparency regarding cost and earnings drivers
  • Sound margin and profitability analyses
  • Basis for planning, forecasts and scenarios
  • Early identification of economic risks

Analysis methods: The P&L as an instrument of corporate management

The mere preparation of the profit and loss statement fulfills the legal obligation, but its true value for entrepreneurs lies in the analysis. Only through the targeted evaluation of the earnings situation does the P&L become a strategic management tool. Two primary methods are the focus of reporting: the total cost method and the cost of sales method.

Total cost vs. cost of sales method

The nature of expense method is widely used in Germany. It compares all expenses incurred in the financial year with total income – including changes in inventories of finished goods and work in progress. The cost of sales method, on the other hand, focuses purely on the costs incurred for the products actually sold. While the total cost method provides a deep insight into the production structure, the cost of sales method is the international standard and facilitates margin analysis per product group.

Earnings situation compared over time (period comparison)

An isolated look at net income is often not enough. Only a comparison over several periods makes trends visible. Are sales revenues increasing while other operating expenses are growing disproportionately? Such developments can only be identified by systematically monitoring data quality and key performance indicators.

Modern controlling: P&L creation with software support

In the modern business world, it is no longer enough to manually compile the profit and loss account once a year in an Excel spreadsheet. The definition of efficient controlling has changed: It’s all about real-time transparency and valid data. Anyone who wants to create a P&L that serves as a real management tool today relies on integrated software solutions that automate the entire process from document to reporting.

Automation through Corporate Planner and Qlik

Software solutions such as Corporate Planner or the BI platform Qlik are revolutionizing the structure and analysis of income statements. Instead of laboriously exporting data from various sources, the values are streamed directly from financial accounting. This not only reduces the error rate when determining the net profit or loss for the year, but also makes it possible to create forecasts during the year. If you want to know who needs to keep a particularly detailed P&L, then it is companies that operate in dynamic markets and are dependent on rapid price corrections.

Data strategy: from accounting to business intelligence

A professional data strategy transforms mere accounting into valuable business intelligence. By linking P&L data with operational key figures, something can be achieved that is hardly possible with traditional methods: the identification of drivers behind costs and sales. With tools such as Qlik, other operating expenses can be drastically visualized down to the individual booking line, making potential savings immediately visible.

Frequently asked questions about the income statement (FAQ)

What is the difference between earnings and liquidity?

A common fallacy is the equation of profit and account balance. While the net profit or loss for the year represents the accounting profit or loss for a period, the cash flow provides information about the actual solvency. Income is posted in the income statement even if payment is not received until the following year.

How often should a P&L be prepared?

By law, the preparation of annual financial statements is mandatory once per financial year. For modern corporate management, however, it is advisable to run monthly or quarterly evaluations (BWA) in order to be able to react to undesirable developments at an early stage.

Why is the P&L so important for investors?

Investors primarily look at the earnings situation and the sustainability of profits. The income statement not only shows the final result, but also provides a detailed breakdown of whether the success stems from the core business (sales revenue) or from one-off special effects (other operating income).
