What is the 50/30/20 rule?
The 50/30/20 rule is the simplest, most-cited budgeting framework. It splits your monthly take-home income into three buckets: 50% needs, 30% wants, and 20% savings and debt. It works because it gives you a clean target without asking you to track every receipt.
How to use this calculator
Type your take-home monthly income — the amount that hits your bank account after tax and mandatory contributions. The calculator instantly shows the three buckets in monthly, weekly, and per-day terms. Daily figures are surprisingly useful: "€20/day for wants" lands harder than "€600/month."
When 50/30/20 stops working
In high-rent cities, needs often eat 55-65% of income. That's not a failure of the rule — it's a signal. Three options: increase income, reduce housing cost, or run a tighter wants bucket (15-20%) and protect at least 10% for savings. The rule is a target, not a law.
