The 50/30/20 rule:
the method that changes everything

6 min read · Updated May 2026

Looking for a simple way to manage your budget without overthinking it? The 50/30/20 rule is probably the most effective and easiest method to apply. In three numbers, it transforms your relationship with money.

What is the 50/30/20 rule?

Popularized by US Senator Elizabeth Warren in her book All Your Worth, the 50/30/20 rule is a method for splitting your budget into three main categories:

50%
Needs
Rent · Groceries · Bills · Insurance · Essential transport · Loan repayments
30%
Wants
Restaurants · Leisure · Travel · Shopping · Streaming subscriptions · Gym
20%
Savings
Emergency fund · Project savings · Investments · Debt repayment

How to apply the 50/30/20 rule

It's simpler than you'd think. Here are the 3 steps:

  1. Work out your net monthly income — net salary + bonuses + side income
  2. Multiply by 0.5 / 0.3 / 0.2 — and you get your monthly envelopes
  3. Track your spending by category and adjust if you go over

💡 Tip: Set up an automatic transfer of 20% of your salary into a savings account on payday, starting today. What you don't see, you don't spend.


The difference between needs and wants

The key distinction of this method: knowing whether an expense is a need or a want.

✅ Needs (50%)

🎯 Wants (30%)


What if my needs exceed 50%?

That's the case for many people, especially in cities where rent is high. If so, adjust the ratios gradually:

The key is to always save something, even 5%. A small regular saving beats a large irregular one.


Frequently asked questions

Does the 50/30/20 rule work on a low salary?

Yes. Adapt the percentages to your situation. Start with 60/25/15 or 70/20/10 if you need to. What matters is having the three categories, not the exact percentages.

Do you need an app for the 50/30/20 rule?

A budgeting app makes tracking far easier. My EasyBudget lets you categorize your spending into needs and wants, and see your three envelopes in real time.

Does the 50/30/20 rule include taxes?

No — you always work from your net salary (after tax). Taxes are deducted at source and aren't part of your available budget.
