P&L is an essential tool that investors and managers need to understand.

P&L is the Profit and Loss Statement, a document summarizing a business’s operational results over a specified period. This financial statement reveals three key points: cash inflows (revenues), cash outflows (expenses), and the final result (profit or loss). Once you understand what P&L is, you’ll be able to clearly assess a company’s financial health.

P&L is an essential document for investment decisions

Many people might think that P&L is just a dry accounting report, but in reality, it’s a green or red light for investing. If a business has high revenue but expenses exceed that, it may show net profit at zero or a negative figure. Conversely, if revenue is less than expenses, it indicates trouble for the company.

The profit and loss statement helps management identify which costs are causing cash leakage and where to cut expenses to increase profits. This makes it indispensable for strategic planning.

Basic P&L formula to remember: Revenue minus expenses equals profit

Calculating P&L is straightforward. The basic formula is:

Total Revenue - Total Expenses = Profit (or Loss)

Each component means:

• Total Revenue: Money earned from selling goods or services
• Total Expenses: All costs incurred in running the business, from rent and advertising to salaries
• Profit or Loss: The difference between the two

If revenue exceeds expenses, the business is profitable; if not, it incurs a loss.

Subtracting cost of goods sold (raw materials and labor) from revenue gives gross profit. Deducting operating expenses (administration, sales) yields EBIT (Earnings Before Interest and Taxes). Further subtracting financial expenses results in EBT (Earnings Before Tax). Finally, subtracting taxes gives Net Income, the true profit.

Different profit levels tell different stories — key points

Profit isn’t just one figure; each level tells a different story:

Gross Profit: Shows how much the business earns above production costs. Low gross profit may indicate high production costs or low selling prices.

Operating Profit (EBIT): Reflects earnings from core operations after deducting operating expenses, indicating management efficiency.

Net Profit: The actual profit remaining after all expenses, including interest and taxes. This is the figure investors focus on most.

Two formats of P&L: how do they differ?

There are two formats for preparing a profit and loss statement, each serving different purposes:

Report Form

This straightforward top-to-bottom layout lists revenue at the top, followed by expenses, and finally the profit or loss at the bottom. It’s easy to understand and suitable for quick overviews.

Advantages:

• Easy to read, following a logical sequence
• Highlights key figures like net profit clearly
• Suitable for presentations to management or general investors

Account Form

This format arranges figures in a T-account style, with expenses on the left and revenues on the right, making both sides visible simultaneously. It’s more formal and commonly used in government agencies and financial institutions.

Advantages:

• Clear and widely accepted academically
• Easier to verify and audit due to standardized structure
• High credibility in auditing and accounting fields

Why is P&L important for management and investors?

Why is the P&L such a critical document? Several reasons:

Measures profitability efficiency: The figures reveal whether the business is effectively generating profit. Is the profit margin 5% or 20%? This indicates performance.

Financial risk indicator: Continuous losses over years signal potential danger.

Investment decision-making: Investors use P&L to evaluate whether to invest and to estimate the true value of their investment.

Profitability planning: Management reviews P&L to decide where to cut costs, raise prices, or find new revenue streams.

How to read a P&L to see the real business picture

Reading a P&L isn’t just about looking at numbers; it requires a strategic approach:

Step 1: Check the period: Is this P&L for a month, quarter, or year? Different periods can show different insights.

Step 2: Identify revenue sources: Does the business have multiple income streams or just one? Relying on a single source can be risky.

Step 3: Analyze expenses: Which costs are the highest? Can they be reduced? Some expenses are necessary; others can be optimized.

Step 4: Compare trends: If multiple years’ P&Ls are available, look for patterns—are profits increasing or decreasing? How are individual expense categories changing?

Step 5: Calculate profit margins: Look at net profit as a percentage of revenue (Net Profit Margin). This indicates operational efficiency.

Summary: P&L reflects the true financial state of a business

The P&L is a chain of data connecting revenue to profit through various expenses. By analyzing it, investors and managers can make informed decisions. To deepen your understanding, consider also reviewing the balance sheet, market trends, and insights from management. Developing a strategic view of P&L will help you make smarter investment choices.
