How the 50/30/20 Budget Rule Works

The 50/30/20 rule divides after-tax income into three categories: 50% for needs, 30% for wants, and 20% for savings and debt repayment.

Ideal Needs = Monthly Income × 50%
Ideal Wants = Monthly Income × 30%
Ideal Savings = Monthly Income × 20%
Difference = Actual Spending − Ideal Amount

Needs include housing, utilities, groceries, insurance, and minimum debt payments. Wants include dining out, entertainment, and subscriptions. Savings includes retirement, emergency fund, and extra debt payments.
