Knowledge

Finance: No rocket science.

Retirement, ETFs and conscious consumption. The basics everyone needs to know — and the ones school never taught.

By Alex Alber · 26. Mai 2026

Talking about money is still an exercise in politeness in Germany. Exactly that is why so many people lose five- or six-figure amounts over a lifetime to inflation, insurance no one needs, and bank products that only help one party — the bank. This article isn't a finance course. It's the summary I wish I'd had at 20.

Finance is not witchcraft

Whether it's a passion or a hate-topic for you, you have to engage with finance. And honestly, this isn't rocket science. If you don't have a handle on it yet, it's most likely because school never made room for it.

5 finance basics everyone needs to know

  1. Track income & expenses

    If you don't know what comes in and goes out, you can't plan.

  2. Invest your money

    Retirement. If you don't invest, inflation eats your purchasing power.

  3. Know your financial products

    Which do you actually need? Which just cost money?

  4. Understand your insurance

    Liability, disability, health — what's a must, what's a nice-to-have.

  5. Do your tax return

    Skipping it is leaving money on the table. Every year.

Retirement — the core topic

The German state pension is a pay-as-you-go system under massive pressure. Demographics make the model unsustainable in the long run.

  1. 1973: 4 workers per retiree

    The system worked because many people paid in.

  2. 2050: only 1.3 workers per retiree

    Who is supposed to pay for that?

  3. Over €100bn tax money for the pension

    Already in 2023 — a quarter of the federal budget.

Bottom line: the state pension is becoming a basic safety net, no longer a way to maintain your standard of living. Private retirement saving is a must.

ETFs & savings plan

All major AI models (ChatGPT, Claude, Gemini, Grok, Perplexity, DeepSeek) agree: broadly diversified world ETFs (FTSE All-World or MSCI ACWI).

Low cost (TER below 0.5 %), broad diversification, historical return around 7-10 % p.a. Better than actively managed funds (too expensive), life insurance (opaque), single stocks (concentration risk), savings accounts (inflation eats the return).

And yet: the savings account is still the most popular form of investment in Germany (45 %).

The best time to start a savings plan is now. Here's what the compound-interest effect can do to your investment:
