The INCOME STATEMENT Explained (Profit & Loss / P&L)

The Income Statement Explained

The income statement—also called the profit and loss statement (P&L)—summarizes a business’s revenues and expenses over a chosen period. Subtracting expenses from revenue shows whether the business made a profit or a loss.

Unlike a balance sheet, which is a snapshot of assets, liabilities, and equity at one point in time, an income statement covers a span of time, such as a month, quarter, or year. It can be viewed as a clip showing how the business reached its financial result.

Main Parts of an Income Statement

1. Revenue

   • Income earned from the business’s activities.
   • It may be labeled more specifically, such as product sales or services rendered.

2. Direct costs

   • Costs that can be traced directly to the products sold or services provided.
   • These may be called cost of sales, cost of goods sold (COGS), or cost of services.
   • Examples include the purchase price of goods for resale, raw materials, and direct labor.
   • These costs generally rise as sales or production increase.

3. Gross profit

   • Revenue − direct costs = gross profit.
   • Gross profit helps assess the efficiency of producing and selling goods or services.

4. Indirect costs, or overheads

   • Costs of running the business that cannot be directly traced to producing goods or providing services.
   • Examples include rent, salaries, insurance, administration, legal and accounting fees, marketing, depreciation, and amortization.
   • Some overheads are fixed, while others—such as advertising, sales commissions, or some utility costs—may vary with business activity.

5. Operating profit

   • Gross profit − indirect operating costs = operating profit.
   • It measures income generated from the business’s operations before interest and tax.
   • It is also known as EBIT: earnings before interest and tax.

6. Net profit

   • Subtract interest and tax from operating profit to arrive at net profit, the “bottom line.”
   • Gross, operating, and net profit each show a different aspect of business performance.

Using the Income Statement to Analyze Performance

• Compare statements across periods—for example, this month versus last month or this year versus last year.
• Track the change in each line item and develop an explanation, or narrative, for significant movements.
• Use ratios such as gross profit margin to examine performance:
  • Gross profit margin = (revenue − COGS) ÷ revenue
  • It indicates how much gross profit the business earns per unit of sales and can help flag changes in selling prices or costs.

Example from the Video

An imaginary business’s sales rise from $100,000 to $110,000, while COGS rises from $30,000 to $40,000. Gross profit stays at $70,000 in both years. With overheads of $45,000, operating profit is $25,000 in both periods.

Although sales increased, gross profit margin fell from 70% to about 64%. That could prompt questions such as whether the business discounted its products or whether input costs rose. Comparing the figures identifies what to investigate; further analysis is needed to explain why the change occurred.
