Many families make the same structural financial mistakes in Germany. Read more.
Most families make their financial decisions one at a time. A savings plan here, an insurance policy there, a building society contract somewhere along the way – each one perhaps sensible on its own, but never thought through as a whole.
The result is a patchwork. And patchworks have holes.
In our conversations with families, we keep seeing the same structural mistakes. Not because the parents did anything wrong, but because nobody ever showed them the full picture. Here are the seven most common ones.
Many families start investing before the basics are secured. It feels productive. It is risky.
Before money is committed long term, three things should be in place: an emergency buffer of roughly three to six months of expenses, income protection (Berufsunfähigkeitsversicherung), and personal liability insurance (Haftpflicht).
The reason is simple: if the car breaks down or an income disappears, the money that was supposed to sit untouched for 18 years is exactly what gets raided. And a savings plan you have to liquidate after three years has failed its purpose.
Foundation first. Then wealth building.
Some families put every spare euro into retirement. Others put everything aside for the child and ignore their own pension.
Both are structural mistakes.
A family has several goals with different time horizons: the emergency buffer (available immediately), medium-term wishes like a car or a home (5 to 10 years), the child's capital (15 to 20 years), and your own retirement (20 to 40 years).
Each pot needs a different approach. Money you need in three years does not belong in ETFs. Money with a 20-year horizon does not belong in a Tagesgeld account.
The mistake is not picking the wrong option. The mistake is treating everything the same.
This is the most emotional mistake on the list, and one of the most expensive.
Many parents set aside every available euro for their child and postpone their own retirement planning. The intention is admirable. The consequence is not.
Because if you are financially stretched in old age, that becomes your child's problem. Leaving your child with a future obligation to support you is not a gift.
Your child can take a loan for their education, apply for BAföG, or work. There is no loan for your retirement.
This does not mean you should not save for your child. It means both have to be planned together – not one against the other.
The most common question parents ask us is: "Which product is best?"
Wrong question.
A product is something you buy. A structure is the decision about how your money is organised: who owns it, when your child gets access, what happens if you move or your income changes, and what it costs you over twenty years.
A good product inside a bad structure will not help you much. A good structure makes the product choice almost incidental.
Concretely, with children's savings: whether the money sits in a depot in your child's name or in an ETF policy where you remain the policyholder is a structural decision. It determines who has control at 18 and whether BAföG is affected. The investment behind it can be the very same ETF in both cases.
Three mistakes that sound less dramatic but add up considerably over the years:
Mistake 5: Ignoring costs. One percent more in ongoing fees sounds like nothing. Over 18 years it eats a noticeable share of your final capital. Ask for the full cost breakdown across the entire term of any product – not just the entry fee.
Mistake 6: Wasting your child's tax allowances. Children have their own allowances, under which investment income of up to roughly 13,384 euros per year can remain tax-free (2026 figures). Most families never use them, because nobody told them about the Freistellungsauftrag and the Nichtveranlagungsbescheinigung.
Mistake 7: Never looking at it again. Families change. A second child, a new job, a move abroad – all of it changes what the right structure looks like. Set up a savings plan once and never touch it, and in five years you will have a structure built for a life you no longer live.
Where should we start?
With the foundation: emergency buffer, income protection, liability insurance. Wealth building comes after. Skipping that order tends to backfire at exactly the worst moment.
Should we save for our child or for ourselves first?
Both belong in one plan. Neglecting your own retirement simply moves the problem down one generation.
How often should we review our financial structure?
At least once a year, and whenever something significant changes: a child, a job, a move, your income.
Do we need advice for all this?
Not necessarily. But if you never ask yourself these questions, you are still making the decisions – just unconsciously.
If you take one thing from this article, let it be this: your finances are not a stack of individual contracts. They are a system in which everything is connected.
The emergency buffer protects the savings plan. Income protection protects both. The structure of your child's capital determines taxes, control and BAföG. And your own retirement provision determines whether your child will later be free, or expected to step in for you.
Most families have never had anyone show them that full picture. That is exactly where we come in.
We are not a tax firm, and we will tell you honestly when you need a specialist Steuerberater or lawyer. But we help you see the structure before you buy the next product.
