  • You don't have a system that works for your lifestyle.

Question
"How do I start budgeting with €3,000/month?"
OMNIBUS Response
Apply the 50/30/20 rule:
€1,500 for needs (50%) – rent, utilities, groceries, transport.
€900 for wants (30%) – dining out, entertainment, shopping.
€600 for savings/investments (20%) – automate this!

If your needs are >50%, cut them. If your wants are >30%, cut them. If your savings are <20%, increase them. OMNIBUS helps you make the adjustments.
