A profit and loss statement (P&L) — also called the income statement or statement of operations — shows how much a company earned or lost over a period. It starts with revenue, subtracts COGS and operating expenses, and ends at net profit — the bottom line.
What Is a Profit and Loss Statement (P&L)?
The P&L is a report card for financial performance over a span of time — a month, quarter, or year. It's one of the three core financial statements alongside the balance sheet and the cash flow statement. Where the balance sheet is a snapshot at one moment, the P&L tracks performance across a period: did the business make money, and where did it go?
P&L = income statement. They're the same document under different names ("statement of operations" is a third). A software company's version may show "Cost of Revenue" (hosting, support) instead of "Cost of Goods Sold," but the structure is identical.
Example P&L Statement
Here's a simple annual P&L for an example company:
| Line item | Amount |
|---|---|
| Revenue | $1,000,000 |
| − Cost of Goods Sold (COGS) | $400,000 |
| = Gross Profit | $600,000 |
| − Operating Expenses | $420,000 |
| = Operating Profit | $180,000 |
| − Interest & Taxes | $50,000 |
| = Net Profit (bottom line) | $130,000 |
What a P&L Includes
| Line | What it means |
|---|---|
| Revenue | Total income from sales or services |
| COGS | Direct cost of producing what was sold |
| Gross profit | Revenue − COGS |
| Operating expenses | Salaries, rent, marketing, utilities |
| Operating profit | Gross profit − operating expenses |
| Other income/expense | Interest, investments, one-offs |
| Net profit/loss | The bottom line after everything |
P&L vs Balance Sheet vs Cash Flow
| Statement | Answers | Time view |
|---|---|---|
| P&L | Are we profitable? | Over a period |
| Balance sheet | What do we own & owe? | Snapshot in time |
| Cash flow | Where did cash move? | Over a period |
Why the P&L Matters
- Profitability: tells owners and stakeholders whether the business makes money.
- Cost control: pinpoints where expenses are highest.
- Trends: comparing P&Ls month over month or year over year reveals whether revenue is growing and margins improving.
Profit and Loss Statement FAQ
Is a P&L the same as an income statement?
Yes. "Profit and loss statement," "income statement," and "statement of operations" are three names for the same report — revenue minus expenses over a period, ending in net profit.
What's the difference between a P&L and a balance sheet?
The P&L shows performance over a period (revenue, expenses, profit). The balance sheet is a snapshot of what a company owns and owes at one moment. You need both for a full financial picture.
How do you read a P&L statement?
Read top to bottom: start at revenue, subtract COGS to get gross profit, subtract operating expenses to get operating profit, then subtract interest and taxes to reach net profit. Each step shows where money is kept or lost.
What period does a P&L cover?
Any defined span — monthly, quarterly, or annually. Comparing the same line items across periods is how you spot trends in growth and profitability.
