What Is the 50/30/20 Budget Rule?
The 50/30/20 rule is a simple way to manage your money by dividing your after-tax income into three main categories:
| Category | Percentage | What It Covers |
|---|---|---|
| 50% – Needs | Half of your income | Essential expenses: rent/mortgage, utilities, groceries, transportation, insurance, etc. |
| 30% – Wants | For enjoyment | Non-essentials: dining out, entertainment, travel, hobbies, etc. |
| 20% – Savings & Debt | Build financial health | Savings, investments, emergency fund, and debt payments beyond minimums. |
🧮 Example:
If your monthly income is $3,000 (after tax):
- 🏠 50% for Needs: $1,500
- 🎉 30% for Wants: $900
- 💵 20% for Savings or Debt: $600
