The income statement is a financial report that shows a company's financial performance over a specific period, often quarterly or annually. It presents revenue, expenses, and the company’s net profit or loss. It is also known as the profit and loss statement.

Income Statement Components:

1. Revenue:

Operating Revenue: revenue generated from the company’s core activity, such as sales of goods or provision of services.
Non-operating Revenue: revenue generated from non-core activities such as interest earned and investments.

2. Cost of Goods Sold (COGS):

Direct costs related to producing goods or providing services, such as raw material costs and direct labor.

3. Gross Profit:

Calculated by subtracting Cost of Goods Sold from Operating Revenue.

\[ \text{Gross Profit} = \text{Operating Revenue} - \text{Cost of Goods Sold} \]

4. Operating Expenses:

Selling and Marketing Expenses: include advertising, promotion, commissions, and sales team costs.
General and Administrative Expenses: include administrative salaries, rent, utilities, office supplies, and insurance.

5. Operating Income:

Calculated by subtracting Operating Expenses from Gross Profit.

\[ \text{Operating Income} = \text{Gross Profit} - \text{Operating Expenses} \]

6. Non-operating Expenses:

Interest Expenses: interest paid on loans and debts.
Investment Losses: losses resulting from investments in shares or bonds.
Extraordinary Expenses: unusual or non-recurring costs.

7. Net Income Before Tax:

Calculated by subtracting Non-operating Expenses from Operating Income.

\[ \text{Net Income Before Tax} = \text{Operating Income} - \text{Non-operating Expenses} \]

8. Income Tax:

Taxes due on net income before tax.

9. Net Income:

Calculated by subtracting Income Tax from Net Income Before Tax.

\[ \text{Net Income} = \text{Net Income Before Tax} - \text{Income Tax} \]
