What is the 50/30/20 rule?

A budgeting framework by Senator Elizabeth Warren: 50% on needs (housing, food, transport), 30% on wants (dining, entertainment, hobbies), and 20% on savings and debt repayment.

What if my rent is more than 50% of my income?

High housing costs are common in expensive cities. If needs exceed 50%, try to reduce wants below 30% to still hit 20% savings. The key is total savings rate, not strict category percentages.

How do I categorize expenses that feel like both needs and wants?

Basic groceries are a need; premium organic brands or frequent takeout are wants. A basic phone plan is a need; the latest flagship phone is a want. A reliable car is a need; a luxury car payment is a want. When in doubt, ask: "Could I survive with a cheaper version?" If yes, the upgrade portion is a want.
