Freelancing on the side

Freelancing next to your job is the most direct way to turn your professional skills into extra income. You sell hours you're already worth — no new skills, no upfront investment.

What it pays

Freelance rates run roughly two to three times your gross employee hourly wage, because the client carries no employer costs or long-term obligations. One day a month at an average rate is quickly an extra €300-600.

How to start without hassle

• Start with one client — a former employer or contact who knows your work.
• Charge a normal rate. Your gross hourly wage × 2.5 is a reasonable starting point.
• Keep the admin light: register as a sole trader (usually one afternoon) and check your country's small-business VAT exemption.
• Check your employment contract for a side-work clause before you start.

What to watch

Set aside about 40% of every invoice for income tax until you've filed once — then you know your real margin. And keep it small enough not to hurt your job or your rest: one fixed evening or day is sustainable, every weekend is not.
