Worked example
$5,000 a month of take-home pay with the 50/30/20 rule. Needs get $2,500, wants get $1,500 and savings and extra debt payments get $1,000 a month, which is $12,000 a year. As a rough guide, housing should stay near $1,500, which is 30% of take-home pay.

Frequently asked questions
What is the 50/30/20 rule?
A budgeting guideline that splits after-tax income into 50% for needs, 30% for wants and 20% for savings and debt repayment.
What counts as a need?
Rent or mortgage, utilities, groceries, insurance, transport to work, minimum debt payments and child care. These are costs you must pay.
What counts as a want?
Eating out, streaming services, travel, hobbies and shopping beyond the basics.
Where do debt payments go?
Minimum payments are needs. Extra payments to clear debt faster come from the 20% savings share.
What if my needs are over 50%?
That is common where housing is expensive. Use the 60/20/20 or 70/20/10 rule and work on reducing fixed costs over time.
Should I use gross or take-home pay?
Take-home pay. Taxes and payroll deductions have already left, so the budget covers only money you can spend.
Does 401(k) count as savings?
Payroll 401(k) contributions are already out of your take-home pay. Some people count them toward the 20%, which lets them put less of the budget toward savings.
How do I track my spending?
Download a month of bank and card statements and sort each transaction into needs, wants or savings. Many banking apps do this automatically, and two or three months give a reliable picture.
Who created the 50/30/20 rule?
It was popularised by Senator Elizabeth Warren and her daughter Amelia Warren Tyagi in the book All Your Worth. It is a starting point, not a strict law, so adjust it to your situation.
How often should I review my budget?
Check it monthly at first, then every few months or whenever your income, rent or household changes.
