Complete Guide to Income Statements
What is an Income Statement?
An Income Statement (also called a Profit & Loss Statement or P&L) is a financial document that
shows a company's revenues, expenses, and profits over a specific period of time (usually a
quarter or year). Think of it as a financial "report card" that tells the story of how much money a
business made, how much it spent, and what's left over as profit.
Simple Analogy
Imagine your personal monthly budget:
Income: Your salary = Company's Revenue
Expenses: Rent, food, utilities = Company's Expenses
What's Left: Savings = Company's Profit
The income statement does exactly this but for businesses!
