Your first paycheck is the best time to build good habits – here are seven rules that will serve you for life.
Your first job – a summer job, after school or after university – brings the first money that is fully yours. Right now is the easiest time to build habits that will save you a lot of stress later. Here are seven rules.
1. Pay yourself first
On payday, move at least 10% into a separate savings account – before you start spending. What you don’t see in your main account doesn’t tempt you.
2. Know where your money goes
Use an app or a simple spreadsheet for at least the first three months. Most money “leaks” through small purchases – coffee, deliveries, games, subscriptions.
3. Build a small emergency fund
Before any big goals, save €500–1,000 for the unexpected. That way you won’t need to borrow when your phone breaks.
4. Be careful with quick loans and “buy now, pay later”
Quick loans and instalments look easy but often cost a lot. Before signing, check the APR – annual percentage rate of charge. It shows the real yearly cost including all fees and is the best way to compare two offers.
5. Protect your credit history
Every loan and credit card is recorded in the BNB’s Central Credit Register. Pay on time – late payments stay on your record and can later make a mortgage or car loan more expensive or harder to get.
6. Start investing early – even with a little
Once you have an emergency fund and no expensive debt, consider long-term investing – for example a broad index fund. Thanks to compound interest, time is your biggest ally: €50 a month started at 20 can grow to much more than €100 a month started at 35. Investing carries risk, so only invest money you won’t need soon, and learn first.
7. When your pay goes up, don’t raise spending right away
When your income grows, increase your savings first and your lifestyle second. Step by step, that gives you the freedom to choose – your job, your home, your travels.
