Income statements

An income statement, also known as a profit and loss account, is a financial statement that reports a company's financial performance over a specific accounting period. It summarizes revenues, costs, and expenses to arrive at net profit or loss.

Revenue is the income generated from normal business activities, usually from the sale of goods and services to customers. It's calculated by multiplying the price of the goods/services by the quantity sold.

Cost of sales refers to the direct costs attributable to the production of the goods sold by a company. It includes the cost of materials, direct labor, and other direct expenses.

Gross profit is the profit a company makes after deducting the cost of goods sold from revenue. The formula is: Gross Profit = Revenue - Cost of Sales. It shows the profit before other expenses are deducted.

Expenses are the costs a business incurs in its normal operations to generate revenue. They include rent, salaries, utilities, marketing, and depreciation. Expenses are deducted from gross profit to calculate net profit.

Net profit is the profit a company makes after deducting all expenses (including operating expenses, interest, and taxes) from gross profit. It differs from gross profit because it represents the *actual* profit after all costs are accounted for.

Profit margin is a measure of profitability that indicates how much profit a company makes for every dollar of revenue. It's calculated as (Net Profit / Revenue) * 100%. A higher profit margin indicates better profitability.
