What is the 50/30/20 budget rule? Learn how to split income into needs, wants and savings, with an example and tips for making it work.

Key takeaway

The 50/30/20 rule splits after-tax income into 50% needs, 30% wants and 20% savings and debt repayment. It is a simple starting point, not a strict law, so adjust the percentages to fit your situation.

What is the 50/30/20 rule?

The 50/30/20 rule is a simple budgeting guideline popularised by Elizabeth Warren (now a U.S. senator) in her book All Your Worth. It divides your after-tax income into three buckets:

Bucket	Share	Examples
Needs	50%	Rent, groceries, utilities, transport, minimum debt payments, insurance
Wants	30%	Dining out, entertainment, hobbies, shopping, subscriptions
Savings & debt	20%	Emergency fund, investments, extra debt repayment

Example

With a monthly after-tax income of 3,000: 1,500 for needs, 900 for wants and 600 for savings and extra debt repayment.

When to adjust it

In high-cost areas, needs may exceed 50%. Trim wants first.
If you carry high-interest debt, shift more of the 20% to repayment.
If you're saving aggressively, reduce wants.
