How to use the 50/30/20 budget calculator

  1. Enter your take-home (after-tax) pay and choose monthly or yearly.
  2. Keep the default 50/30/20 split or adjust the percentages.
  3. Use the dollar amounts as monthly spending targets.

How it's calculated

Monthly take-home pay × each percentage. By default 50% goes to needs (housing, utilities, groceries, insurance, minimum debt payments), 30% to wants (dining, entertainment, travel) and 20% to savings and extra debt payments. The three percentages should add up to 100%.

Example

With $5,000 of monthly take-home pay, the 50/30/20 rule suggests about $2,500 for needs, $1,500 for wants and $1,000 for savings and extra debt payments.

Tips

  • If needs exceed 50%, trim wants first rather than cutting savings to zero.
  • Count extra debt payments beyond the minimum as part of your 20%.
  • Review your budget every few months or whenever your income changes.
  • Try 60/20/20 or 70/20/10 if you live in a high-cost area. The framework is flexible.

Frequently asked questions

What is the 50/30/20 rule?
A simple budgeting framework popularized by Senator Elizabeth Warren and Amelia Warren Tyagi in the book "All Your Worth": spend about 50% of after-tax income on needs, 30% on wants and 20% on savings and debt repayment.
Is it based on gross or net income?
Net, meaning your take-home pay after taxes and deductions. If retirement contributions come out of your paycheck, you can count them toward the 20% savings bucket.
What counts as a need versus a want?
Needs are expenses you must pay to live and work: rent or mortgage, utilities, groceries, insurance, transportation and minimum loan payments. Wants are everything else: streaming, dining out, vacations, upgrades.
What if 50/30/20 doesn't work for me?
Change the percentages. The goal is to spend intentionally and save consistently, not to hit exact numbers. High-cost areas often need a larger needs share.
