The profit and loss statement, often called the P&L, is a summary of your business's income and expenditure over a given period. It tells you whether the business made money, and how much. Most owners glance at the bottom line and move on. But the real value comes from understanding the numbers in between.
Revenue vs Profit
Revenue is the total income your business generated before any costs are deducted. Profit is what is left after costs. It is entirely possible for a business to have strong revenue and still make a loss, which is why turnover alone is not a measure of financial health.
The P&L typically shows three levels of profit: gross profit (revenue minus direct costs), operating profit (gross profit minus overheads), and net profit (operating profit after interest and other items).
Direct Costs vs Overheads
Direct costs
These are costs that vary directly with the work you do or the goods you sell. For a service business this might be subcontractor costs or materials used on a specific job. For a product business it is the cost of goods sold. Direct costs reduce your gross profit.
Overheads
These are the fixed costs of running the business regardless of how much work you do. Rent, salaries, insurance, software subscriptions, and professional fees all fall here. Overheads reduce your operating profit.
Key Metrics to Monitor
Gross margin percentage
Gross profit divided by revenue, expressed as a percentage. This tells you how much of each pound of revenue you retain after paying your direct costs. If your gross margin is falling, either your prices are too low or your direct costs are rising.
Overhead ratio
Total overheads divided by revenue. This tells you how much of your revenue is consumed by fixed costs. Generally, as the business grows, this ratio should fall as revenue scales faster than overheads.
Net margin percentage
Net profit divided by revenue. This is the ultimate measure of profitability. What a healthy net margin looks like will vary significantly by sector.
A Practical Example
Emma runs a recruitment business. Her revenue is £400,000, her direct costs (candidate sourcing and job boards) are £80,000, giving a gross profit of £320,000 and a gross margin of 80%. Her overheads are £260,000, leaving an operating profit of £60,000 and a net margin of 15%. She knows that adding one more recruiter will increase overheads by £45,000 but should generate at least £120,000 in new revenue, improving her net margin to around 18%.
Key Takeaways
- Revenue is total income; profit is what remains after costs
- The P&L shows gross profit, operating profit, and net profit at different stages
- Direct costs vary with activity; overheads are fixed regardless of volume
- Gross margin percentage tells you how efficiently you deliver your product or service
- Net margin is the ultimate measure of profitability; tracking it over time reveals trends early
