The profit and loss statement is the report that tells you whether your business actually made money. Once you can read it, you can spot problems early and make better decisions. This guide breaks a P&L down line by line and shows what to look for.
What is a profit and loss statement?
A profit and loss statement (P&L), also called an income statement, summarises your revenue and expenses over a period — a month, quarter or year — and shows the profit or loss left at the end. Where a balance sheet is a snapshot in time, the P&L covers what happened over a period.
The parts of a P&L, in order
| Line | What it means |
|---|---|
| Revenue (sales) | Total income from sales in the period |
| Cost of goods sold (COGS) | Direct cost of the products you sold |
| Gross profit | Revenue minus COGS |
| Operating expenses | Rent, wages, marketing, admin and other running costs |
| Operating profit | Gross profit minus operating expenses |
| Net profit | What is left after all costs, interest and tax — the bottom line |
How to read it line by line
Start at the top with revenue, then subtract COGS to get gross profit — the money left to run the business after paying for the goods themselves. Subtract operating expenses to get operating profit, then interest and tax to reach net profit, the true bottom line. Each step answers a different question: are my products profitable? Is my overhead under control? Am I actually making money overall?
What to look for
- Margins, not just totals. Track gross and net margin as percentages — see calculating profit margin and gross vs net profit.
- Trends over time. Compare periods. A falling gross margin or creeping expenses show up here first.
- Big or unusual lines. Anything that jumps deserves a look.
P&L vs balance sheet
The P&L shows performance over a period; the balance sheet shows what you own and owe at a point in time. You need both for the full picture — see what is a balance sheet.
