The short answer
A profit and loss statement (P&L, or income statement) shows how much your business earned, what it cost to earn it, and what was left over for a period. It runs from revenue at the top, through cost of sales and gross profit, to operating expenses, interest, tax and finally net profit. Read monthly, it is the clearest single view of whether your business model is working.

The lines of a P&L, top to bottom
Revenue
Income from selling your goods or services, excluding VAT if you are VAT registered. Loans, owner deposits and refunds from suppliers are not revenue.
Cost of sales
Costs directly linked to what you sold: stock, raw materials, direct labour, subcontractors on a job. Service businesses may have small or no cost of sales.
Gross profit
Revenue minus cost of sales. It shows how much each sale contributes before overheads.
Operating expenses
Overheads that keep the business running regardless of individual sales: rent, admin salaries, marketing, insurance, data, accounting fees, bank charges.
EBITDA
Earnings before interest, tax, depreciation and amortisation. It is gross profit minus operating expenses, before those four items. Lenders sometimes use it as a rough measure of cash earning power. It is not a formal accounting line and can flatter businesses with heavy equipment needs.
Depreciation
Spreads the cost of long-term assets like vehicles or machines over their useful life. It is an expense with no cash movement in the period.
Interest
Interest on loans, overdrafts and asset finance. Capital repayments are not expenses; they reduce the loan on the balance sheet.
Profit before tax and net profit
Profit before tax is what remains after interest and depreciation. Net profit is after income tax. Your tax practitioner works out the actual tax, which can differ from accounting profit because of tax rules.
Example: a Cape Town coffee roastery, 12 months
- Revenue: R2,400,000
- Cost of sales (beans, packaging, roaster wages): R(1,224,000)
- Gross profit: R1,176,000 (gross margin 49%)
- Operating expenses (rent, admin, marketing, delivery): R(816,000)
- EBITDA: R360,000
- Depreciation on roaster and van: R(96,000)
- Operating profit: R264,000 (operating margin 11%)
- Interest on equipment loan: R(38,000)
- Profit before tax: R226,000
Hypothetical figures for illustration only.
Margins that matter
| Measure | Formula | What it tells you |
|---|---|---|
| Gross margin | Gross profit ÷ revenue | Pricing power and direct cost control |
| Operating margin | Operating profit ÷ revenue | Efficiency after overheads |
| Net margin | Net profit ÷ revenue | What you keep from every R100 of sales |
Key takeaway
A rising revenue with a falling gross margin often means you are discounting too much or supplier costs are rising faster than your prices.
How to read trends
- Compare each month with the same month last year, not just last month, to allow for seasonality
- Watch costs as a percentage of revenue, not only in Rands
- Look for once-off items (a big repair, a large order) and note them
- Track year-to-date totals against your budget or targets
Monthly vs annual P&L
The annual P&L forms part of your annual financial statements and tax return. A monthly P&L, usually part of management accounts, lets you react within weeks instead of discovering a problem a year later.
Common errors
- Including VAT in revenue and expenses when VAT registered
- Counting loans, owner deposits or transfers as income
- Treating loan capital repayments or asset purchases as expenses
- Mixing personal expenses into the business
- Putting direct costs into overheads, which distorts gross margin
- Forgetting depreciation
A P&L only shows performance. Pair it with a balance sheet and cash flow statement for the full picture.
