What is the 50/30/20 rule?
The 50/30/20 rule splits your after-tax income into three buckets: 50% for needs, 30% for wants, and 20% for savings and debt. US Senator Elizabeth Warren popularised it in her book All Your Worth in 2005. It has stuck around because it is simple enough that people actually follow it.
You do not track every coffee or grocery receipt. You just know which bucket each spending category falls into, and you check the totals once a month.
Worked example
Monthly take-home pay: 3,500 euros
Needs, 50%
1,750 euros
Rent, groceries, utilities, insurance
Wants, 30%
1,050 euros
Dining, subscriptions, leisure
Savings, 20%
700 euros
8,400 euros saved in a year

Needs vs wants: where does each expense go?
This is where most people get stuck. A need is something you cannot reasonably live or work without. A want improves your life but you could cut it if you had to.
Needs (50%)
- ·Rent or mortgage payment
- ·Basic groceries
- ·Utilities: gas, water, electricity
- ·Health insurance (verplichte basisverzekering)
- ·Minimum loan and credit card payments
- ·Essential transport to work
Wants (30%)
- ·Restaurant meals and takeaway
- ·Netflix, Spotify and other subscriptions
- ·Gym membership
- ·Clothing beyond the basics
- ·Weekend trips and holidays
- ·Hobbies and entertainment
Grey areas exist everywhere. A car is a need in a rural area and a want in central Amsterdam. A smartphone is a need; an expensive model is partly a want. Use your judgement. The goal is awareness, not punishment.
What should the 20% savings actually do?
In this order:
- 1.
Emergency fund first: Build three to six months of essential expenses in a liquid savings account. Do this before anything else. Without it, any unexpected cost turns into debt.
- 2.
Clear high-interest debt: Credit card debt at 20% costs more than almost any investment earns. Pay it off before you invest a single euro.
- 3.
Pension contributions: If your employer matches pension contributions, take the full match. That is an instant 100% return. Nothing comes close.
- 4.
Invest the rest: Index funds tracking global markets are the default choice for most people. Use the Compound Interest calculator to see what 700 euros per month becomes at 7% over 20 years.
When 50/30/20 does not fit your situation
High housing costs
Amsterdam, Utrecht and other expensive cities
Shift to 60/20/20 or even 65/15/20. Protect the savings percentage as much as you can. If rent is eating 40% of your income, that is a housing problem, not a budgeting problem.
Carrying high-interest debt
Credit cards, personal loans above 10%
Temporarily go to 50/20/30. Redirect that extra 10% from wants to debt repayment. Once the debt is cleared, move back to 50/30/20 and redirect the old payment to savings.
Lower income or just starting out
Early career, part-time work, student income
Start with 50/40/10 or even 50/45/5. Any savings habit is better than none. Build the savings rate gradually as income grows.
The exact percentages matter less than the habit. Spend less than you earn, save something every month, and increase the savings rate when you can.
