An Income Statement, also known as a Profit and Loss Statement, summarizes a company's revenues, expenses, and profits over a specific period. It highlights how revenue is transformed into net income, showcasing operational efficiency. Key components include total revenue, cost of goods sold (COGS), gross profit, operating expenses, and net profit. Businesses use the Income Statement to assess financial performance, make strategic decisions, and ensure profitability. Investors and stakeholders analyze it to gauge the company’s financial health and future growth potential.
