growney in Germany: ETF robo-advisor, fees, taxes and risks

What growney is and who it suits

growney is a German robo-advisor for investing in ETFs. It is suitable for people who want to invest for the long term in a diversified portfolio but do not want to choose funds themselves, calculate allocations, rebalance, or deal with every tax transaction manually.

For people who have moved to Germany, growney can be an understandable entry point into the market: registration is online, the portfolio is built from ETFs, and the German banking infrastructure helps with tax documents. But this is not a savings deposit and it does not guarantee returns. The portfolio value can fall, especially in strategies with a high equity share.

The service is usually a good fit if you:

• invest for several years or longer;
• want a regular ETF-Sparplan without buying funds manually;
• are willing to pay a fee for automation;
• live in the German tax system or want German tax documents;
• understand that an ETF portfolio can decline in value.

If you need the money as a reserve in the next few months, it is better to look not at an ETF portfolio but at Tagesgeld or Festgeld. If the lowest possible fee and full control matter more, it is more logical to open a brokerage account in Germany and buy ETFs yourself.

How ETF-Vermögensverwaltung works

growney offers ETF-Vermögensverwaltung - portfolio management through ETFs. The client answers questions about their goal, timeline, amount, experience, and attitude toward risk. The service then suggests a strategy and shows how the money will be allocated among funds.

The focus is not on choosing individual stocks but on a portfolio of ETF investment funds. The service monitors the portfolio structure: new contributions are directed in a way that brings the allocations closer to the selected strategy, and rebalancing is carried out when necessary.

The key logic is this: the higher the share of equities, the higher the potential long-term return, but also the deeper the possible drawdowns. The more bonds or money market exposure there is, the steadier the portfolio is, but the expected growth is usually lower.

growney strategies

growney has classic strategies and sustainable growgreen strategies. The names show the approximate equity share in the portfolio: for example, grow30 is aimed at a more cautious profile, while grow100 is a fully equity-based strategy.

Group	Example strategies	Who it usually suits
Conservative	growCash, grow0	For a very cautious approach and low tolerance for volatility
Mixed	grow30, grow50, grow70	For investors who want a balance between growth and drawdowns
Equity-heavy	grow100	For a long investment horizon and high risk tolerance
Sustainable	growgreen0, growgreen30, growgreen50, growgreen70, growgreen100	For those who want an ESG or sustainability focus in an ETF portfolio

The availability of specific strategies and the option to switch may depend on the account date and growney’s terms. Before opening an account, it is worth checking the current list in the personal dashboard or on the service’s website.

Minimum amount and top-ups

For growney’s ETF management, you can start with a one-time investment from 500€ or a monthly contribution from 25€. After opening an Anlageziel, the monthly amount can be changed, paused, and supplemented with additional contributions via SEPA.

Short summary:

Parameter	What matters
One-time start	From 500€
Sparplan	From 25€ per month
Additional contributions	Possible via SEPA direct debit or bank transfer
Pause contributions	Usually available
Withdraw money	Possible partially or in full, but depends on selling ETFs and bank processing
Transfer an existing portfolio	Should not be treated as a standard scenario: conditions need to be checked in advance

The low minimum contribution makes the service accessible, but a small amount does not eliminate investment risk. An ETF portfolio makes sense only if you are ready to live through market swings and do not plan to pull the money out urgently after the first downturn.

growney fees

growney has two important categories of costs: the service’s own fee for ETF-Vermögensverwaltung and the internal costs of the ETFs. The growney fee depends on the average amount of assets in ETF management during the billing period.

ETF management fees:

Assets in ETF-Vermögensverwaltung	growney fee	What else to consider
Up to 50,000€	0.68% per year	Plus internal ETF costs
From 50,000€	0.38% per year	Plus internal ETF costs

On its support page, growney states that the total fee for the ETF management service ranges from 0.25% to 0.68% per year, and the specific level depends on the product and the amount invested. The internal ETF costs are not billed separately by growney, but they do reduce fund performance in practice.

Compared with buying ETFs yourself through a broker, this is more expensive. The difference is the price of portfolio selection, automation, rebalancing, reporting, and easier management.

Returns and risks

growney does not promise a fixed percentage return. Performance depends on the market, the chosen strategy, currencies, ETF composition, the investment term, and the investor’s own behavior. Historical scenarios in the planner are useful for orientation, but they are not a forecast.

Main risks:

• the value of ETFs can fall;
• a strategy with a high equity share can decline more sharply;
• currency fluctuations can affect the result;
• selling at a bad moment locks in a loss;
• sustainable strategies can behave differently from the broad market;
• taxes withheld and fees reduce the final return.

A robo-advisor lowers the risk of mistakes in manual management, but it does not remove market risk. That is why, before opening an account, it is more important to choose the right risk profile than to search for the “highest-return” strategy.

Example accumulation

Below is only a mathematical illustration, not a growney forecast and not a promise of returns.

Scenario	Assumed average annual return	Result before taxes and fees
10,000€ upfront + 200€ per month for 25 years	4%	About 130,000€
10,000€ upfront + 200€ per month for 25 years	6%	About 183,000€
10,000€ upfront + 200€ per month for 25 years	8%	About 264,000€
25€ per month for 30 years	4% / 6% / 8%	About 17,000€ / 25,000€ / 37,000€

These figures show the power of time and consistency. But in real life the result will be lower or higher because of market movements, taxes, fees, and the timing of purchases.

This is what the growney planner looks like when building an investment portfolio.

Reliability, Sondervermögen, and the partner bank

The ETFs in the portfolio count as Sondervermögen - segregated fund assets. This means the fund assets are legally separate from the property of the management company, the custodian bank, and growney itself. If growney runs into problems, those assets should not become part of the service’s insolvency estate.

Cash balances on the banking side are subject to the rules of bank deposit protection. For deposits in countries of the European Economic Area, basic protection is usually up to 100,000€ per client and bank. At the same time, ETFs and cash balances are different risk categories: ETFs are not protected against market declines, and deposit protection does not turn an investment portfolio into a guaranteed product.

growney’s materials refer to partner banking infrastructure including Sutor Bank. Before opening an account, it is worth checking the current contractual documents, because partner banks and service conditions can change.

Taxes in Germany

For tax residents of Germany, ETF income usually falls under Abgeltungssteuer: 25% capital gains tax plus Solidaritätszuschlag and, if applicable, Kirchensteuer. Tax can arise on dividends, on sales at a profit, and through the Vorabpauschale for funds.

growney states that for German tax residents, the partner bank side usually withholds the relevant taxes automatically. To reduce withholding, an investor can submit a Freistellungsauftrag if they still have unused Sparerpauschbetrag allowance. In 2026, the basic Sparerpauschbetrag is 1,000€ per person or 2,000€ for spouses or partners if used jointly.

If you are not a German tax resident, the situation is more complex: growney may provide a tax certificate, but the obligation to declare income in the country of residence usually remains with the investor. Non-standard cases are best discussed with a tax adviser.

How to open a growney account

Opening an account is done online. You will usually need an email address, a mobile phone, identification, tax details, and a euro reference account compatible with SEPA. You should be comfortable with German: the questionnaire covers risk, experience, tax status, and contractual terms.

Steps:

1. Choose ETF-Vermögensverwaltung on the growney website.
2. Fill in the questionnaire about your goal, timeline, amount, experience, and risk.
3. Review the proposed strategy and portfolio composition.
4. Enter your personal, banking, and tax details.
5. Complete identification, for example via PostIdent or another available method.
6. Deposit a one-time amount from 500€ or set up a Sparplan from 25€ per month.
7. Once the money arrives, wait for the ETF purchase and check the portfolio in your account.

Before the final confirmation, it is worth checking three things: the strategy, the fee, and the tax settings. A mistake in the risk profile or a missing Freistellungsauftrag may matter more than the difference between similar ETFs.

Who growney is not suitable for

It is better not to choose the service if:

• you may need the money in the next few months;
• you are not ready to see a temporary loss in the portfolio;
• you need a guaranteed return;
• you want to choose the ETFs, exchange, and timing of purchase yourself;
• the robo-advisor fee seems unjustified to you;
• your tax or civil status is unusual and the service does not confirm that you can open an account.

For a long-term passive investor, growney can be a convenient form of automation. But it is a financial product with fees and risk, not a universal replacement for a broker, a bank deposit, or individual financial advice.
