What is the 50/30/20 budget rule explained simply?

The 50/30/20 rule is a straightforward budgeting framework where you divide your after-tax income into three categories. You spend 50% on needs, which are essentials like rent, groceries, utilities, and transportation. You spend 30% on wants, meaning non-essentials like dining out, entertainment, and hobbies. The remaining 20% goes toward savings and debt repayment, covering things like an emergency fund, retirement contributions, or paying down credit cards. For example, if you take home $4,000 a month, that means $2,000 for needs, $1,200 for wants, and $800 for savings. The rule is popular because it's simple and flexible, giving you a clear structure without tracking every single purchase in detail.
