What the 50/30/20 rule says

The 50/30/20 budget divides your income after tax into three groups. It was popularised by Senator Elizabeth Warren and her daughter Amelia Warren Tyagi in their book All Your Worth.

  • 50% for needs: housing, utilities, groceries, transport, insurance, minimum debt payments and other things you cannot easily skip.
  • 30% for wants: dining out, entertainment, subscriptions, hobbies, travel and upgrades.
  • 20% for savings and extra debt payments: emergency fund, retirement contributions, investing and payments beyond the minimum.

Example

With $4,000 a month after tax, the rule gives $2,000 for needs, $1,200 for wants and $800 for savings and debt payoff. That is $9,600 a year going toward your future.

Adjusting the rule to your life

The percentages are a starting point, not a law. If rent is high where you live, needs may take 60% or more, and you can shrink wants to keep saving. If you have expensive debt, you might choose 50/20/30 to speed up repayment. Use the boxes above to try a split that works, and check that the three add up to 100%.

How to put it into practice

  1. List your fixed monthly bills and see whether they fit inside the needs share.
  2. Automate the savings transfer for the day you are paid.
  3. Track spending for a month or two to find where the wants share really goes.
  4. Adjust the split and revisit it whenever income or expenses change.

Frequently asked questions

What is the 50/30/20 rule?

A budgeting guideline that puts 50% of after-tax income toward needs, 30% toward wants and 20% toward savings and debt repayment.

Should I use income before or after tax?

After tax, meaning your take-home pay. The rule is meant to divide the money you actually receive.

Where do minimum debt payments go?

Minimum payments are usually counted as needs. Extra payments beyond the minimum count toward the savings and debt category.

What if the 50/30/20 split does not fit my situation?

Change the percentages. In high-cost areas or on a lower income, a split such as 60/20/20 or 70/20/10 may be more realistic.
