The 50/30/20 Budget Rule Explained

The simple formula that takes the guesswork out of budgeting.

The 50/30/20 rule is one of the most popular budgeting methods because it's dead simple: split your after-tax income into three buckets—50% for needs, 30% for wants, and 20% for savings.

How It Works

50%

Needs

Rent, utilities, groceries, insurance, minimum debt payments—things you can't skip.

30%

Wants

Dining out, entertainment, shopping, subscriptions—nice to have, not essential.

20%

Savings

Emergency fund, retirement, investments, extra debt payments.

A Real Example

Let's say you take home $5,000/month after taxes:

Needs (50%)$2,500
Wants (30%)$1,500
Savings (20%)$1,000

Needs vs Wants: The Tricky Part

The hardest part is being honest about what's a need vs a want:

✅ Needs

  • • Rent/mortgage
  • • Basic groceries
  • • Health insurance
  • • Utilities
  • • Transportation to work
  • • Minimum debt payments

🎯 Wants

  • • Dining out
  • • Netflix, Spotify
  • • New clothes (beyond basics)
  • • Vacations
  • • Upgraded phone
  • • Gym membership

50/30/20 vs Zero-Based Budgeting

The 50/30/20 rule gives you guardrails, but zero-based budgeting gives you precision. With zero-based, you assign every single dollar to a category until you hit $0.

Many people start with 50/30/20 to get the basics down, then graduate to zero-based budgeting for more control.

When 50/30/20 Doesn't Work

This rule isn't perfect for everyone:

How to Get Started

  1. 1. Calculate your after-tax income — What actually hits your bank account.
  2. 2. List your fixed expenses — Rent, utilities, subscriptions.
  3. 3. Categorize as needs or wants — Be ruthless here.
  4. 4. Set up automatic transfers — Move 20% to savings on payday.
  5. 5. Track for a month — See where you actually land.
