Why does this matter? Fixed costs leave your account even if you do nothing. Variable costs are the ones you can change quickly.
Where does Alex's money go?
Alex is 16. Money in: €50 pocket money + €100 from a weekend job = €150 income. Money out:

| Phone contract | fixed | €20 |
| Bus pass | fixed | €30 |
| Snacks & food out | variable | €25 |
| Games & fun | variable | €30 |
| Gifts | variable | €10 |
🤔 Income €150, expenses €115. What is Alex's balance at the end of the month?

€150 − €115 = €35 left. That is a positive balance — money Alex can save or spend next month. Next lesson we turn this into a real budget.
