My son is hoping he'll never have to work or will become the CEO of a company that works FOR him... After discussing the matter he's interested in investing... So I put the case bevore ChatGPT and COPILOT.
I gave both AI-models the same prompt, including my location, the age of my son, the expected career path and costs of living alone and buying a house, creating a realistic budget to start investing with. Then I asked them to advice me, based on that path on how to invest... Both came up with similar plans and only one comparison by both was needed to let them agree on a strategy, here is the blog both of them made afterwars about this 'talk' - I did ask to disclose any information about my son...

How Long Does It Take to Live Off Investments? A Realistic European Perspective

Many people—especially young investors—ask a deceptively simple question:

“How long do I need to work before I can live off my investments?”

The answer is not just about returns. It’s about income, discipline, costs, and time. This article breaks down a realistic long-term strategy for a European investor aiming to generate €2,000 per month from a portfolio without depleting capital.

🎯 The Target: Financial Independence

To sustainably withdraw €2,000 per month (€24,000 per year), a commonly used guideline is the 4% rule.

• Required capital:€24,000 ÷ 0.04 = €600,000

For safety, a more realistic target is:

👉 €700,000 – €800,000

📈 The Core Insight: Savings Rate Matters More Than Returns

A typical long-term return assumption of ~7% annually is reasonable for global equity investing.

However, the real driver of success is not returns—it’s how much you invest.

Small monthly investments lead to very long timelines. Increasing contributions over time dramatically accelerates the path to financial independence.

🧮 A Realistic Career-Based Scenario

Phase 1: Early Career

• Modest savings capacity
• Limited investment contributions

Phase 2: Income Growth

• Salary increases over time
• Investment capacity rises significantly

Phase 3: Major Expense Ends (e.g., mortgage)

• Large monthly cash flow becomes available
• Investment contributions surge

⏳ Timeline Outcome

Under realistic assumptions:

• Early years: slow progress
• Mid-career: strong accumulation
• Later years: rapid growth due to compounding + higher contributions

👉 Financial independence is typically reached after ~30 years of investing

➡️ This translates to stopping work around age 50–55 in a disciplined, single-income scenario.

🚀 What Accelerates the Timeline?

Even small optimizations can save years:

• Increasing monthly investments
• Reducing housing costs
• Growing income faster
• Avoiding lifestyle inflation

👉 An extra €300–€500/month invested can reduce the timeline by 5–10 years

📦 The Investment Strategy (Simple Wins)

Portfolio Approach

• Use one globally diversified ETF
• Prefer accumulating funds (tax-efficient in many European countries)
• Avoid unnecessary complexity

Example Strategy

• Invest monthly (or quarterly if amounts are small)
• Always buy the same ETF
• Never try to time the market

👉 Simplicity beats sophistication.

🧠 The Real Challenge: Behavior

The biggest risk is not the market—it’s the investor.

Success requires:

• Staying invested during crashes
• Ignoring market noise
• Continuing contributions consistently
• Avoiding panic selling

👉 Most of the growth happens after decades, not in the beginning.

🏦 Choosing the Right Broker

Two valid approaches emerge:

Low-Cost Broker

• Slightly better long-term returns
• Requires handling some administrative tasks

Full-Service Local Broker

• Handles taxes automatically
• Simpler and safer for beginners
• Slightly higher costs (but negligible long-term impact)

👉 For most investors, especially beginners:

Ease of use and consistency matter more than minimizing fees.

🧭 Final Takeaway

If this entire strategy had to be reduced to one sentence:

Invest consistently in a global ETF, keep costs reasonable, and stay the course for 30 years.

Financial independence is not about finding the perfect investment.

It’s about building a system you can follow—reliably—for decades.

📊 Bottom Line

• Target: €700k–€800k
• Strategy: simple global ETF investing
• Timeline: ~30 years
• Key driver: savings rate + discipline

👉 The earlier you start, the more time does the heavy lifting.

Consistency is the real edge.

How to Build a Long-Term Investing Strategy for Young Belgian Investors (2026 Guide)

For young professionals in Belgium, especially those just starting their careers, the road to financial independence can seem abstract and far away. Yet with the right structure, portfolio design, and broker choice, even modest monthly contributions can grow into a powerful investment engine over time.

This guide summarises a complete, practical roadmap: how to choose the right broker, which ETFs to use, and how to invest consistently for decades—while navigating the unique Belgian tax landscape.

1. The Core Challenge: Simple, Reliable, Decades‑Long Investing

Young investors need a plan that satisfies four requirements:

1. Extremely low effort – something that can run for 30+ years.
2. High long-term growth – achieved through global equity exposure.
3. Low cost – because fees drastically reduce long-term returns.
4. Belgian tax efficiency – avoiding unnecessary withholding taxes and administrative burdens.

The strategy must be resilient, simple, and easy to maintain—even during market crashes.

2. The Optimal Portfolio: One ETF Is Enough

While investors are often tempted to pick multiple funds, themes, or even individual stocks, this typically reduces performance and adds unnecessary complexity.

✔ Best choice: VWCE

Vanguard FTSE All‑World UCITS ETF (Acc)

• Globally diversified across developed + emerging markets.
• Accumulating: dividends are automatically reinvested.
• No 30% Belgian dividend withholding tax because nothing is distributed.
• Ideal for long-term Belgian investors.

This single ETF gives exposure to thousands of companies worldwide—more than enough diversification for decades.

Alternative (if someone prefers a 2‑ETF setup):

• IWDA (MSCI World, developed markets)
• EMIM (Emerging Markets)

But honestly: VWCE alone is the cleaner and more effective choice for almost everyone.

3. Investment Strategy: Automation Beats Timing

The most important habits for long-term success are:

🔁 Use a fixed investment rhythm

• Monthly investing is ideal.
• At very small contribution sizes, investing every 2–3 months (bundling orders) can reduce transaction costs.

❌ Do NOT attempt to time the market

• No “waiting for a dip.”
• No “the market is too expensive.”
• Time in the market beats timing the market.

🌧 Keep investing during crashes

This is the secret that separates those who reach financial independence from those who do not.

4. Broker Selection: DEGIRO vs. Belgian Brokers vs. Saxo

There is no universal “best broker.”
Different profiles require different choices:

✔ Why many young investors start with DEGIRO

• Ultra‑low transaction costs.
• Perfect for small, frequent contributions.
• Large ETF selection.

However, DEGIRO does not handle Belgian taxes automatically and requires:

• NBB foreign account declaration,
• Manual checks for TOB (beurstaks),
• Additional annual admin.

✔ Why Saxo is often the better long-term home

According to detailed Belgian broker comparisons, Saxo:

• Handles all Belgian taxes automatically (TOB, dividend taxes, Reynders tax).
• Does not require NBB account declaration.
• Offers low ETF transaction fees (~€2 per order).
• Makes long-term investing seamless and administration‑free.

This makes it particularly suitable for a decades‑long, FIRE‑oriented plan.

Realistic combined approach

A dual-phase plan works well:

Phase 1 — Early career (small contributions):

• Start with DEGIRO to minimise costs.

Phase 2 — As wealth grows (100k–200k+):

• Optionally transfer to Saxo or Bolero for complete administrative simplicity.

5. How to Invest Step-by-Step

1. Open a broker account (DEGIRO to start, Saxo if simplicity is preferred).
2. Add VWCE to your favourites list.
3. Set a recurring transfer from your bank to the broker.
4. Invest the same amount on the same day every month (or quarter).
5. Reinvest automatically and stay the course.
6. Ignore market noise.
7. Never panic‑sell.
8. Adjust strategy only after approaching financial independence.

6. When to Add Bonds or Extra Diversification

Before ~€500k in portfolio size, young Belgian investors rarely benefit from adding bonds or complex allocations.

After reaching higher wealth levels, adding a small bond allocation (10–20%) can reduce volatility—but it is not necessary for growth during the first decades.

7. The Mindset That Makes This All Work

To succeed, an investor must be ready to:

• See little progress for the first 8–10 years.
• Continue investing even when markets fall 30–50%.
• Resist the urge to pick stocks or chase themes.
• Trust the compounding engine to do the heavy lifting.

The simple truth:
Consistency beats brilliance.

8. Final Summary: The Entire Plan in One Sentence

“Use DEGIRO (or Saxo), buy VWCE regularly, never sell, and let time do the rest.”

This ultra‑simple structure is the most robust long-term wealth‑building plan for young Belgian investors today. It respects Belgium’s tax rules, maximises growth, minimises mistakes, and keeps the investor on track for financial independence—even if they never become “a financial expert.”
