How much should I save?

Only you know best 😊 Do a calculation: what is my income and what are the expenses. The difference can go towards savings. As an exercise, think about what the amount needed would be to cover your necessary expenses for a period or how much money you would need to buy something you need but do not have the full amount.

And more practical - if you want to buy a laptop that costs 5,000 lei and you have an income of 4,000 lei/month, you will need to make a budget with all the expenses, prioritize them (what you can give up, what you cannot). Then calculate how much money you can set aside to buy the laptop and how many months it would take.
