Quick Take & Executive Summary
The 50/30/20 rule splits income into needs (50%), wants (30%), and savings/debt payoff (20%). Most people don't overspend—they misclassify wants as needs, letting wants erode savings and create debt. Before buying, ask: need, want, or future regret? If you can't answer in five seconds, pause. Naming each expense protects your 20%, turning small pauses into lasting wealth.
