What is the 50/30/20 Budget Rule?
The 50/30/20 budget rule is a simple, effective budgeting framework popularized by Senator Elizabeth Warren. It divides your after-tax income into three categories: 50% for Needs (essential expenses), 30% for Wants (discretionary spending), and 20% for Savings and Debt Repayment.
This budgeting method provides a balanced approach to personal finance that ensures you cover essential expenses while still enjoying life and building financial security. It's particularly effective for people who find detailed budgeting overwhelming but want a structured approach to managing their money.
