What is a P&L (income statement)?
The P&L, or profit and loss statement, known in statutory language as the income statement, shows what a company earned and spent over a period. Revenue sits at the top, net profit or loss at the bottom, and the lines in between explain where the money went. If the balance sheet is a photograph, the P&L is the film of the period.
The flow follows the same skeleton almost everywhere: cost of goods or services comes off net sales to give gross profit; operating expenses (marketing, general and administrative, R&D) come off next to give operating profit; finance items and tax leave the net result for the period. Most startup metrics are derivatives of these lines: gross margin is gross profit over sales, EBITDA is operating profit before depreciation and amortisation, and burn rate emerges once the P&L is read together with cash flow.
| Line | What it tells you | What investors read |
|---|---|---|
| Net sales | Revenue for the period | Growth rate, recurring share |
| Gross profit | What remains after cost of sales | Whether the margin scales |
| Operating profit | What remains after opex | Efficiency, unit economics |
| Net profit / loss | The period’s final result | Runway and financing need |
On the legal side the P&L is not decoration: under the Turkish Commercial Code the financial statements go to the general assembly for approval, and dividends can only be distributed against them. In financing rounds it is among the first documents requested in due diligence, and a P&L in the data room that matches the management accounts is the quiet precondition of a smooth closing.
How is the P&L different from the balance sheet?
The P&L covers a period, the balance sheet a moment. Everything earned and spent during the period flows through the P&L; what is left at period end, with debt and equity, sits in the balance sheet. The two connect through the bottom line: the P&L’s net result feeds the equity section of the balance sheet.
Why does the P&L matter for loss-making startups?
Because investors read direction, not profit. The trend of gross margin, the ratio of operating expenses to revenue and which line the loss comes from say far more about whether the business scales than the net result does. A loss-making P&L with improving margins is a better story than a profitable one with margins melting away.
