What is the 50/30/20 budget rule?

The 50/30/20 rule allocates after-tax income: 50% to needs (housing, food, utilities), 30% to wants (entertainment, dining out), and 20% to savings and debt repayment.

Does the 50/30/20 rule work in expensive cities?

In high-cost areas, 50% for needs may be unrealistic. Many people adjust to 60/20/20 or 55/25/20. The savings rate is what matters most - try to keep at least 20% for financial goals.

How do I track my budget?

Use our budget calculator to start, then automate transfers to savings on payday. Apps like Mint, YNAB, or even a simple spreadsheet work. The best tracking method is the one you'll actually use.

What if my expenses are higher than my income?

First, separate needs from wants. Cut wants first, then look at needs (cheaper housing, phone plan, insurance). If still short, increase income via side work or selling unused items.
