Learn › Budgeting

In short: Start with an overview: list all income and expenses, sort them with the 50/30/20 rule and work out your monthly balance. Only once you know where your money goes can you steer it.

Budgeting basics – get the overview

It all starts with an overview: knowing where your money goes leads to better decisions. This is the foundation for everything else.

  • List your income and fixed expenses once, cleanly.
  • Group your spending – the 50/30/20 rule (needs / wants / saving) is a handy guardrail.
  • Work out your monthly balance: is anything left at month's end? If not, start here.
  • Set aside a buffer for irregular costs (insurance, repairs).

What matters

The most common trap is underestimating small, recurring costs. A coffee on the go, three streaming subscriptions, the odd delivery – harmless alone, but easily a few hundred a month together. So track every expense for one month; you'll often find €50–100 of slack without really giving anything up. If you live with a partner or flatmates, agree early on who pays what – it prevents arguments and double-spending.

ExampleA €3 coffee-to-go on workdays is about €63 a month – over €750 a year. A budget makes exactly these small items visible.

Common myths

Myth: Budgeting means forbidding yourself everything.

Reality: It is about overview and conscious choices – not deprivation.

Myth: I earn too little to budget.

Reality: That is exactly when every euro counts – on a tight budget an overview helps most.

Frequently asked questions

What is the 50/30/20 rule?

A rough guardrail: about 50 % of net income for needs (housing, food), 30 % for wants and 20 % for saving. The figures are guidelines, not law.

How do I start budgeting?

Track all income and expenses for a month, group them and look at the balance. That overview alone already changes spending behaviour.
