What Is the 50/30/20 Budget Rule?

The 50/30/20 rule is a simple budgeting framework popularised by Senator Elizabeth Warren. It suggests dividing your after-tax income into three categories: 50% for needs, 30% for wants, and 20% for savings and debt repayment. It works as a starting point regardless of your currency or country.

How to Categorise Your Spending

Needs (50%) are essential expenses you cannot avoid: rent or mortgage payments, groceries, utility bills, insurance premiums, minimum debt payments, and transportation to work.

Wants (30%) are non-essential spending that improves your quality of life: dining out, streaming subscriptions, gym memberships, hobbies, and vacations.

Savings & Debt (20%) covers building an emergency fund, retirement contributions, additional debt payments beyond minimums, and investing for future goals.

Customising Your Ratios

The 50/30/20 split is a guideline, not a rule. If you live in an expensive city, your needs might require 60%. If you are aggressively paying off debt, you might allocate 40% to savings. Use the sliders above to adjust the ratios to your situation.

Getting Started With Budgeting

  • Track spending for one month to see where your money currently goes.
  • Automate savings — set up automatic transfers on payday.
  • Review monthly — adjust categories as your income or goals change.
  • Be realistic — a budget you follow imperfectly beats one you abandon.
