What is 50/30/20 Rule?

The 50/30/20 rule splits your after-tax income: 50% for needs, 30% for wants, and 20% for savings and debt repayment. Under this system, after-tax (net) income is divided into three distinct categories: 50% for 'Needs' (essential fixed costs like housing and groceries), 30% for 'Wants' (discretionary variable spending like travel and dining), and 20% for 'Savings' and debt payoff (such as retirement contributions and extra principal payments).

This proportional framework simplifies budgeting by focusing on broad categories rather than line-by-line tracking. It ensures that critical obligations are met, personal enjoyment is funded, and long-term financial security is systematically built through consistent savings and debt reduction.
