The 50/30/20 rule is a simple budget: split your after-tax income into three parts. 50% goes to needs, 30% to wants, and 20% to savings and extra debt payments.
It was popularized by Elizabeth Warren and her daughter Amelia Warren Tyagi in their 2006 book All Your Worth: The Ultimate Lifetime Money Plan, as The Wall Street Journal and Bankrate both note. Here is how it works, with an example and a way to set it up in 15 minutes.
What is a budget, and why this one?
A budget is a plan for where your money goes each month. Many people quit budgeting because tracking dozens of categories is tiring. The 50/30/20 rule only has three, which makes it easy to start and easy to keep.
The three parts of 50/30/20
50% for needs
Things you must pay to live and work:
- Rent or mortgage
- Utilities and phone
- Groceries (not restaurants)
- Transportation to work
- Insurance
- Minimum loan and credit card payments
30% for wants
Things you enjoy but could live without:
- Eating out and takeaway
- Streaming and subscriptions
- Hobbies, trips and events
- Clothes beyond the basics
20% for savings and debt
Money for your future:
- Emergency fund
- Retirement savings
- Debt payments above the minimum
- Goals like a home deposit
A worked example
Say your take-home pay is $3,000 a month after tax.
- Needs: 50% of $3,000 = $1,500
- Wants: 30% of $3,000 = $900
- Savings and debt: 20% of $3,000 = $600
If you earn side hustle income, add it to your after-tax total, or put all of it toward the 20% to speed up your goals.
How to set up a 50/30/20 budget
- Find your monthly take-home pay (after taxes).
- Multiply it by 0.5, 0.3 and 0.2 to get your three limits.
- Look at last month’s bank and card statements. Mark each expense as need, want or savings.
- Compare what you spent to your limits.
- Set up an automatic transfer to savings on payday, so the 20% happens first.
A simple spreadsheet works well. Make three columns (needs, wants, savings), list each expense, and total them. A free budget template in Google Sheets is enough.
Hux explains five money habits that quietly hurt your budget, starting with not having one:
What if your needs are more than 50%?
This is common, especially with high rent. Don’t give up on the rule. Treat 50/30/20 as a target, not a test you fail.
- Take from wants first, not savings. A 60/20/20 split still builds savings.
- Look for the biggest need you can lower over time: rent, car payment or phone plan.
- Add income with a side hustle. Our side hustle ideas for beginners is a good place to look.
Pros and cons
Pros
- Easy to understand and remember.
- Builds savings into every month.
- Allows guilt-free spending on wants.
Cons
- Can be hard on low incomes or in expensive cities.
- “Needs” vs “wants” can be blurry. Be honest with yourself.
- Doesn’t tell you how to split the 20% between savings and debt.

Minimum payments count as needs. Anything above the minimum goes in the 20%.
