A profit and loss statement shows whether your business is actually making money. Learn what goes in a P&L, how to read one, and how to create one even if you're not an accountant.
What Is a Profit & Loss Statement?
A profit and loss statement (P&L), also called an income statement, is a financial report that summarises your business's revenues, costs, and expenses over a specific period — usually a month, quarter, or year.
It answers the most important question in business: are you making money or losing it?
Even if you have a healthy bank balance right now, without a P&L you don't know whether your business is genuinely profitable or just benefiting from timing — clients paying early, bills not yet due.
The Structure of a P&L Statement
A profit and loss statement follows a simple structure:
Revenue (Income)
Total money earned from selling goods or services. This is your top-line number.
Cost of Goods Sold (COGS)
The direct costs of producing your products or delivering your services — materials, direct labour, manufacturing costs. Not all businesses have COGS (service businesses often don't).
Gross Profit
Revenue minus COGS. This is how much you made before operating expenses.
Gross Profit = Revenue − Cost of Goods SoldOperating Expenses
All costs not directly tied to production: rent, utilities, salaries, software subscriptions, marketing, insurance.
Operating Profit (EBIT)
Gross profit minus operating expenses.
Other Income / Expenses
Interest income, bank charges, one-off items.
Net Profit (or Net Loss)
The bottom line. What's left after everything is deducted.
Net Profit = Revenue − All Costs and ExpensesA Simple Example
Imagine a small landscaping business for the month of June:
The owner generated $18,000 in revenue but kept $7,320. That's a 40.7% net profit margin — healthy for a service business.
How to Read Your P&L
Gross Profit Margin
(Gross Profit ÷ Revenue) × 100Shows how efficiently you're producing your product or delivering your service. A declining gross margin means your costs are rising faster than your prices.
Net Profit Margin
(Net Profit ÷ Revenue) × 100The percentage of each pound or dollar you actually keep. Industry benchmarks vary widely — retail might be 2-5%, software can be 20-30%+.
Month-over-Month Comparison
Looking at one month in isolation tells you little. Compare months to spot trends: is revenue growing? Are expenses creeping up?
Common P&L Mistakes
Mixing personal and business expenses. A personal car service bill sitting in your business expenses distorts your P&L and creates tax complications. Keep accounts separate.
Forgetting depreciation. If you bought equipment, that cost should be spread over its useful life — not all recognised in the month you bought it.
Cash basis vs accrual. A cash-basis P&L records income when received and expenses when paid. An accrual-basis P&L records them when earned or incurred. For most small businesses, cash basis is simpler; accrual is more accurate for decision-making.
Not reviewing it monthly. A P&L you look at once a year is almost useless. Monthly review lets you spot problems and opportunities before they compound.
