There is a dangerous myth that you need to earn €10,000 a month to become wealthy. I see this limiting belief stop parents from investing every single day.
The truth? Wealth is not about what you earn. It is about what you keep.
I have clients earning €3,000 a month who have bigger portfolios than doctors earning €15,000. Why? Because the doctor spends €15,000. The average earner spends €2,500 and invests the "Gap" of €500 consistently for 20 years.
This article is not about cutting lattes. It's about building a Wealth System that works automatically, even while you sleep.
Key Takeaways
- The "Gap" Rule: Wealth comes from the difference between your income and your expenses. Your goal is to widen this gap, not just increase income.
- Automation is Key: Willpower fails. Systems don't. Automate your investments to leave your account the day after payday.
- Time > Money: Investing €300/month starting at age 25 is worth more than investing €600/month starting at age 45.
- The "Boring" Path: Real wealth is built through boring, consistent purchases of global index funds, not lucky crypto bets.
The Math of the "Average" Millionaire

Let’s look at the numbers. Most people think €300 a month is "nothing." They wait until they have "more money" to start. This is a tragedy.
If you invest €300 a month into a simple S&P 500 or Global ETF (averaging 8% annual return):
- 10 Years: €54,000
- 20 Years: €177,000
- 30 Years: €447,000
- 40 Years: €1,054,000
You became a millionaire on €300 a month. That is the cost of a car payment or a few dinners out. The secret isn't the amount; it's the consistency.
Step 1: Pay Yourself First (The Golden Rule)
Most families follow this broken formula:
Income - Expenses = Investments (If anything is left)
Usually, nothing is left. Parkinson's Law states that "expenses expand to match income."
The Wealth Formula is:
Income - Investments = Expenses
Set up an automatic transfer for the day after your salary hits. Move that €300 (or €500, or €1,000) into your brokerage account before you even see it. You will naturally adjust your spending to what remains.
Step 2: The "Set and Forget" Portfolio
You are a busy parent. You do not have time to read earnings reports or watch charts.
You need a portfolio that manages itself. For 90% of families, a 2-Fund Portfolio is all you need:
| Fund Type | Role | Allocation (Age < 45) |
|---|---|---|
| Global Stock ETF (e.g., VWCE / IWDA) | Growth engine. Owns 3,000+ companies globally. | 80-90% |
| Bond ETF / Cash | Safety net. Reduces volatility. | 10-20% |
That's it. Keep buying these two every month forever. When the market crashes, buy more. When the market booms, buy more.
Step 3: The "Lifestyle Creep" Trap
Here is where most people fail. They get a raise at work, and immediately buy a nicer car or move to a bigger house.
If you get a €500 raise, the smart move is to apply the 50% Rule:
- Spend 50% (€250) on improving your lifestyle. Enjoy it!
- Invest 50% (€250) into your freedom fund.
This way, your lifestyle improves and your wealth accelerates. You never feel deprived, but you never fall behind.
Conclusion: Start Today
The only wrong time to start was yesterday. The second wrong time is "tomorrow."
Open your banking app right now. Set up a recurring transfer for €50. Just start the habit. You can increase the amount later, but you cannot buy back the lost time.
