The short answer

An ETF is a fund that holds many investments at once and trades on the stock exchange, like a share. Most copy an index, cost little per year and can be bought monthly with a savings plan.

One basket, many companies

You don't have to pick single companies. You buy one fund that holds hundreds or thousands of them. ETF stands for exchange-traded fund, which just means you buy and sell it on a stock exchange, like a share.

Why bother with a basket? Try it. Put imaginary money in one company, then in a basket of 100, and see what a bad year does to each.

Play with it

€1,000 in one company, or spread over 100?

All in one company€1,000
An ETF: 100 companies, €10 in each
An ETF basket€1,000

Made-up numbers to show the idea. Real ETFs don't hold every company in equal amounts, and real markets can fall by more than 20%.

What could €300 a month turn into?

Meet Alex. He's hypothetical, the rules are real. He invests €300 every month in an ETF that tracks companies from many countries. Here's one possible path, with every assumption on the table.

What happens

Estimated value after 30 years€281,411

Alex pays in €108,000. The rest, about €173,411, is growth earning more growth.

Why

Most of the growth shows up late, so time does a lot of the work. Fund costs look tiny, yet without them the result would be about €10,943 higher.

Assumes 6% a year before costs, payments at the end of each month, no taxes, no inflation. Real markets move up and down. Change Alex’s numbers

What's inside, and what it costs you

The index. Most ETFs copy an index, a list of companies chosen by fixed rules. Nobody picks stocks on a hunch. If the index changes, the fund follows.

MSCI World
MSCI ACWI · FTSE All-World
MSCI EM

Developed marketsEmerging markets

Which markets common world indices cover. Bars show coverage, not weights.

The cost. The fund charges a yearly fee called the TER (total expense ratio). It's taken from the fund itself, so you never see a bill. What an ETF really costs

Income. An accumulating fund (Acc) reinvests dividends for you. A distributing fund (Dist) pays them into your account. Accumulating vs distributing

Buying regularly. Many people in Germany use a Sparplan, a savings plan that buys the ETF automatically every month. How a savings plan works

Before you buy your first one

  • Check three things in the name and factsheet: the index, the yearly cost and Acc or Dist.
  • Most broad stock ETFs count as equity funds in Germany. That matters for tax.
