The moment you consider hiring someone, the question is rarely philosophical. It is practical. Can I afford this? Will the revenue cover the salary? What will it do to my cash flow, my margins, my peace of mind? For micro and small business owners, one extra employee is not a statistic. It is a fixed monthly obligation that arrives whether or not your invoices are paid on time.

We often think in terms of gross salary. But an employee costs more than what lands in their bank account. There are employer contributions, holiday pay, pension premiums, insurance, sick leave risks, and the administrative load that comes with Dutch labour law. If you fall under a collective labour agreement (cao), you also have binding salary scales and conditions. In simple terms: the number on the contract is only the starting point. The real cost can easily be 30 to 40 percent higher.

So when is someone “rendabel” profitable? Not when they are busy. Not when they reduce your stress. And not even when turnover increases. An employee becomes profitable when the additional gross margin they generate structurally exceeds their total employment cost. That word matters: structurally. A few good months do not make a business model. You need predictable revenue that comfortably covers the fixed monthly cost, including quieter periods.

Take a small consultancy that hires a junior professional. If that person bills 30 hours per week, it sounds solid. But if clients pay after 60 days, while salaries leave your account every month, you are financing growth yourself. Add one period of illness, and the calculation shifts again. Profitability is not only about turnover; it is about timing, margin, and risk.

For micro-entrepreneurs, the safest approach is to calculate backwards. Start with the full annual employment cost. Divide that by your average gross margin percentage. The outcome tells you how much additional turnover is required just to break even. Only beyond that point does hiring start contributing to profit. If that required turnover feels ambitious or fragile, the risk is already visible.

None of this means you should not hire. Growth often requires people. But hiring should follow stability, not create it. A healthy order book, disciplined invoicing, clear contracts, and a buffer for slower months make an employee an investment rather than a gamble.

In the end, profitability is not about squeezing productivity out of people. It is about clarity. When you understand the real numbers behind a contract, you make calmer decisions. And calm decisions, in small business, are usually the most profitable ones.
