An income statement, also known as a profit and loss statement or P&L, is a financial document that summarizes a company’s revenues, costs, and expenses over a specific period, typically a fiscal quarter or year. It’s used to assess the company’s financial performance and profitability.
Key Components of an Income Statement:
-
Revenue/Sales:
- Description: The total amount of money earned by the company from its core business operations during the period.
- Formula: Revenue = Price per Unit × Number of Units Sold
-
Cost of Goods Sold (COGS):
- Description: The direct costs attributable to the production of the goods sold by the company. This includes material and labor costs involved in production.
- Formula: COGS = Opening Inventory + Purchases - Closing Inventory
-
Gross Profit:
- Description: The difference between revenue and COGS. It indicates how efficiently a company uses its resources to produce goods.
- Formula: Gross Profit = Revenue - COGS
-
Operating Expenses:
- Description: The costs required to run the business that are not directly tied to the production of goods. This includes selling, general and administrative expenses (SG&A), research and development (R&D), and depreciation.
- Formula: Operating Expenses = Selling Expenses + Administrative Expenses + Depreciation Expenses
-
Operating Income (Operating Profit):
- Description: The profit realized from normal business operations. It measures the efficiency of the core business activities.
- Formula: Operating Income = Gross Profit - Operating Expenses
-
Other Income/Expenses:
- Description: Additional income or expenses not directly related to the core operations, such as interest income, interest expense, gains or losses from the sale of assets, etc.
- Formula: Other Income/Expenses can vary but is generally presented as a line item in the statement.
-
Net Income Before Tax:
- Description: The profit before accounting for income tax expenses.
- Formula: Net Income Before Tax = Operating Income + Other Income - Other Expenses
-
Income Tax Expense:
- Description: The tax obligation incurred due to earnings before tax.
- Formula: Income Tax Expense = Tax Rate × Net Income Before Tax
-
Net Income (Net Profit):
- Description: The total profit of the company after all expenses and taxes have been accounted for. It’s an indicator of the company’s profitability and is often referred to as the "bottom line."
- Formula: Net Income = Net Income Before Tax - Income Tax Expense
Summary Formula for Net Income
Putting it all together, the relationship can be summarized as follows:
\[ \text{Net Income} = (\text{Revenue} - \text{COGS}) - \text{Operating Expenses} + \text{Other Income} - \text{Other Expenses} - \text{Income Tax Expense} \]
