50/30/20 Rule: The Complete Guide to Managing Your Budget

Discover the 50/30/20 budget rule, a simple and effective method to allocate your income and reach your financial goals.

What is the 50/30/20 rule?

The 50/30/20 rule is a budgeting method popularized by Elizabeth Warren that helps you allocate your net income in a balanced way:

  • 50% for your essential needs - Rent, groceries, bills, transportation, insurance
  • 30% for your wants and leisure - Dining out, entertainment, subscriptions, shopping
  • 20% for your savings - Emergency fund, projects, investments

How to apply the 50/30/20 rule?

1. Calculate your monthly net income

Add up all your after-tax income: salary, bonuses, supplemental income. This is your calculation base.

2. Allocate according to the 50/30/20 rule

Example with $3,000 net income per month:

  • $1,500 for needs (50%)
  • $900 for wants (30%)
  • $600 for savings (20%)

3. Track your expenses regularly

Use a budget app like Trya to automatically categorize your expenses and check that you're sticking to the percentages.


The 3 categories in detail

These are the non-negotiable expenses for daily living:

  • Rent or mortgage
  • Groceries
  • Utilities (water, electricity, gas)
  • Transportation (fuel, transit pass)

  • Healthcare (insurance, doctor visits)

30% - Wants and leisure

What makes life enjoyable but isn't essential:

To build your financial security and fund your projects:

The advantages of the 50/30/20 rule

  • Simple to understand and apply — No need to be a finance expert, the rule is clear and easy to follow.
  • Life/savings balance — Lets you enjoy the present (30% leisure) while preparing for the future (20% savings).

Our tips for success

1. Automate your savings

Set up an automatic transfer of 20% to your savings account on payday.

2. Adjust the percentages if needed

If your needs exceed 50% (high rent), temporarily adjust to 60/25/15 for example.

3. Use Trya to track automatically

The app categorizes your expenses and tells you if you're following the 50/30/20 rule.

4. Reassess regularly

Check every quarter that the allocation still matches your situation.
