Profit and loss statement: understanding your business profitability
Introduction
Your bank account shows a positive balance, but is your business truly profitable? The answer lies in your profit and loss statement, the accounting document that measures the economic performance of your business.
Unlike a bank statement that simply shows what remains in your account, the profit and loss statement compares your income (your revenue) and your expenses (your costs) to determine whether you are making or losing money. It's the difference between having available cash and generating actual profit.
For many self-employed individuals and SME managers, this document remains mysterious. Yet knowing how to read and interpret it enables you to make informed decisions: adjust your prices, reduce certain expenses, invest at the right time.
This guide explains how the profit and loss statement works, how to read it simply, and above all how to use it practically to improve your business profitability. You will discover key indicators such as gross margin and net profit, common mistakes to avoid, and how to integrate this analysis into your daily management.
📌 Summary (TL;DR)
The profit and loss statement compares your income (revenue) and your expenses (costs) to measure your actual profitability, independently of your bank balance. By analysing the different levels of profit (gross margin, operating profit, net profit) and calculating your profitability ratios, you quickly identify problematic items and make informed decisions to improve your business performance.

What is a profit and loss statement?
The profit and loss statement is an accounting document that measures the economic performance of your business over a given period, usually an annual financial year.
Unlike the balance sheet which provides a snapshot of your assets at a specific moment, the profit and loss statement is like a film: it traces all your income and expenses over 12 months.
Its role is simple: to determine whether your business is making or losing money. In Switzerland, it is mandatory for certain legal forms (SA, Sàrl) and strongly recommended for all self-employed individuals who wish to manage their business effectively.
The three components of the profit and loss statement
The profit and loss statement is based on a simple logic that every entrepreneur must master:
Income - Expenses = Result
This formula summarises your entire economic performance. Income represents what comes into your business, expenses what goes out, and the result indicates whether you are profitable or not.
Understanding each of these three elements allows you to identify precisely where your gains come from and where your resources go.
Income: what comes in
Income includes all revenue generated by your professional activity.
It mainly comprises:
- Sales of goods or services
- Financial income (interest received)
- Other operating income (subsidies, reimbursements)
Practical example: A freelance graphic designer invoices 80,000 CHF for services during the year, receives 500 CHF in bank interest and receives 2,000 CHF in cantonal subsidy. Their total income amounts to 82,500 CHF.
Expenses: what goes out
Expenses represent all costs necessary to generate your income.
They include:
- Purchases of raw materials or goods
- Salaries and social security contributions
- Rent, insurance, electricity
- Marketing and advertising costs
- Administrative and accounting fees
- Equipment depreciation
- Financial charges (loan interest)
Example: Our graphic designer spends 15,000 CHF on software, 8,000 CHF on social security contributions, 6,000 CHF on marketing, 12,000 CHF on rent and 4,000 CHF on miscellaneous costs. Total expenses: 45,000 CHF.
The result: your profitability
The net profit is the final amount that indicates whether your business is profitable or loss-making.
A positive result means a profit, a negative result indicates a loss.
Example: Our graphic designer generates 82,500 CHF in income and 45,000 CHF in expenses. Their net profit is 37,500 CHF (profit).
Warning: The result is not available cash flow. You can be profitable but lack liquidity if your clients do not pay. To understand your actual cash flows, consult our guide on the cash flow statement.
How to read a profit and loss statement simply
Here is a numerical example of a simplified profit and loss statement for a Swiss SME:
INCOME
Turnover: 250,000 CHF
Financial income: 1,000 CHF
Total income: 251,000 CHF
EXPENSES
Purchases of goods: 80,000 CHF
Salaries and social security contributions: 90,000 CHF
Rent and charges: 18,000 CHF
Marketing: 12,000 CHF
Administrative costs: 8,000 CHF
Depreciation: 5,000 CHF
Financial charges: 2,000 CHF
Total expenses: 215,000 CHF
NET PROFIT: 36,000 CHF
This line-by-line presentation allows you to quickly identify your main sources of revenue and your most significant expense items.
Levels of profit to know
The profit and loss statement is not limited to the final result. There are several intermediate levels that allow you to analyse profitability at different levels of your business.
Understanding these different levels helps you identify precisely where your financial strengths and weaknesses come from.
Gross margin
The gross margin measures your pure commercial profitability, before all other expenses.
Formula: Turnover - Cost of goods/services sold
Example: A restaurant generates 200,000 CHF in turnover and purchases 70,000 CHF in raw materials. Its gross margin is 130,000 CHF, or 65% of turnover.
This ratio indicates whether your selling price adequately covers your direct costs. A gross margin that is too low signals a pricing problem or purchases that are too high.

Operating profit (EBIT)
The operating profit (or EBIT: Earnings Before Interest and Taxes) measures the pure operational performance of your business, before interest and taxes.
Formula: Gross margin - Operating expenses (salaries, rent, marketing, etc.)
Example: Our restaurant with 130,000 CHF gross margin spends 85,000 CHF on salaries, rent and miscellaneous costs. Its operating profit is 45,000 CHF.
This level reveals whether your core business is profitable, regardless of your financial structure.
Net profit
The net profit is the final amount after all expenses, including loan interest and taxes.
Example: Our restaurant has an operating profit of 45,000 CHF. After deducting 3,000 CHF in interest and 8,000 CHF in taxes, its net profit amounts to 34,000 CHF.
This is the amount that actually remains available to the business. It can be placed in reserves in equity or distributed to partners.
Net profit is the ultimate indicator of your overall profitability.
Interpreting your profit and loss statement
Having a profit and loss statement is not enough: you still need to know how to analyse it to make informed decisions.
Three approaches allow you to fully exploit your financial data and identify levers for improving your profitability.
Calculate your profitability ratios
Ratios transform your raw figures into comparable and actionable indicators.
Gross margin rate: (Gross margin / Turnover) × 100
Example: 130,000 / 200,000 × 100 = 65%
Net margin rate: (Net profit / Turnover) × 100
Example: 34,000 / 200,000 × 100 = 17%
A gross margin rate of 50-70% is generally healthy for services, 30-50% for retail. The net margin rate varies greatly by sector, but 10-20% is considered good.

Compare over time
Analysing a single financial year is not enough. Comparing your results over several periods reveals trends.
Example: Your turnover increases from 200,000 CHF (year N-1) to 250,000 CHF (year N), a +25% increase. But your gross margin drops from 65% to 58%.
This situation signals a problem: your purchasing costs are increasing faster than your selling prices. You need to either renegotiate your purchases or adjust your rates.
Also identify expenses that are evolving abnormally: a sudden increase in marketing costs without an increase in turnover should alert you.
Identify problematic items
Calculate the weight of each expense as a percentage of turnover to spot deviations.
Method: (Expense / Turnover) × 100
Example: Your marketing costs represented 6% of turnover last year (12,000 / 200,000). This year, they rise to 10% (25,000 / 250,000).
If this increase is not accompanied by a proportional growth in sales, your marketing return on investment is decreasing. You need to analyse the effectiveness of your campaigns and adjust your strategy.
Common mistakes to avoid
Even with a well-established profit and loss statement, certain interpretation errors can distort your analysis and decisions.
Here are the three most common pitfalls that entrepreneurs encounter.
Confusing profit and cash flow
A positive result does not mean you have money in the bank.
Example: You make 50,000 CHF profit, but your clients pay at 60 days. You need to buy equipment now and repay a 30,000 CHF loan. Result: you are profitable but without liquidity.
Payment delays, investments and loan repayments do not appear in the profit and loss statement but impact your cash flow.
To understand your actual cash flows, consult our guide on the cash flow statement.
Forgetting non-cash expenses
Some expenses impact your result without immediate cash outflow.
Depreciation spreads the cost of an investment over several years. You buy a computer for 3,000 CHF in cash, but in accounting you depreciate it over 3 years (1,000 CHF/year).
Provisions anticipate future expenses (disputes, warranties). They reduce your result but do not leave your bank account.
Understanding these mechanisms prevents overestimating your available cash flow.
Only looking at the final result
Being satisfied with the net profit without analysing the detail masks structural problems.
Example: Your net profit is stable at 30,000 CHF. But by breaking it down, you discover that your gross margin has dropped by 10% and only an exceptional decrease in financial charges compensates.
This situation is fragile: your commercial profitability is deteriorating. Next year, without this exceptional element, you will be in difficulty.
Always analyse each level of profit to understand where your performance comes from.
Using your profit and loss statement daily
The profit and loss statement is not just a mandatory annual document. It is a management tool that should guide your decisions throughout the year.
Regularly monitor your income and expenses to anticipate your final result. Invoicing software like BePaid allows you to track your turnover in real time and export your data to facilitate analysis.
For even finer management, organise your invoicing by project. This allows you to analyse the profitability of each assignment and adjust your rates. Discover how to manage costs and margins by project.
Warning: BePaid does not replace your accounting, but it centralises essential information to manage your business daily and prepare your financial analyses.
The profit and loss statement gives you a clear view of your profitability by distinguishing what comes in (income) and what goes out (expenses). By understanding the different levels of profit, gross margin, operating profit and net profit, you quickly identify where your business generates value and where it loses money.
The key is not to limit yourself to the final result. Analyse your profitability ratios, compare your performance over time and identify problematic items. And above all, do not forget: profit does not mean cash flow. A business that is profitable on paper can lack liquidity if clients pay late.
To effectively manage your business, combine your profit and loss statement with rigorous monitoring of your invoices and payments. Try BePaid for free to automate your invoicing, track your receipts in real time and maintain control over your daily profitability.
