The 50/30/20 Rule
Classic budgeting rule: 50% of after-tax income for needs (housing, food, transport), 30% for wants (entertainment, travel, shopping), and 20% for savings and investments. If your needs exceed 50%, review which expenses can be reduced.
Housing Under 30%
It's generally recommended that housing costs (rent/mortgage) stay under 30% of after-tax income. If you're over, consider a roommate, moving, or refinancing.
Emergency Fund
Keep 3-6 months of essential expenses as an emergency fund. This tool shows how much you can allocate monthly toward building that fund.
Where Does Discretionary Income Go?
If you have good discretionary income but end the month with nothing, it's likely "lifestyle inflation" — expenses rising with income. Try "pay yourself first": automatically transfer 20% to savings on payday.
