What is a Profit and Loss Statement?
A Profit and Loss (P&L) statement, also known as an income statement, is one of the three primary financial statements used by businesses (alongside the balance sheet and cash flow statement). Its purpose is to provide a snapshot of a company’s performance over a specific timeframe—typically a quarter or year.
The P&L statement answers crucial questions such as:
- Is the company profitable?
- How efficiently is it managing its expenses?
- Are revenues growing over time?
Key Components of a P&L Statement
Understanding the sections of a P&L statement is crucial for analysis. Here’s a breakdown:
1. Revenue (Top Line)
Revenue represents the total amount of money a company earns, often referred to as the "top line."
Types of Revenue:
- Operating Revenue: Income from core business activities (e.g., sales).
- Non-Operating Revenue: Secondary income, such as interest or asset sales.
What to Look For:
- Is revenue growing consistently over time?
- Are there seasonal patterns or significant fluctuations?
2. Cost of Goods Sold (COGS)
COGS includes the direct costs of producing goods or services (e.g., raw materials, labor).

- Marketing

What to Look For:
- Are operating expenses under control relative to revenue?

Consistent EBIT growth is a strong indicator of a healthy business.
6. Net Profit (Bottom Line)

What to Look For:
- Is net profit positive and growing?
- Declining net profit despite revenue growth can indicate inefficiencies.

Key Metrics to Evaluate a P&L Statement
