OSKAR review 2026

OSKAR works with a volume-dependent scale: for investment amounts below €10,000, 1.0% p.a. applies, between €10,000 and €50,000 0.8% p.a., and from €50,000 0.7% p.a. As with all providers, we assess the entry level because it is the one that matters for the majority of private investors. Depot management is free, and performance-based fees do not apply. The external product costs of the financial instruments used are 0.14% p.a. for the OSKAR klassik strategies, which puts them among the lowest in the rating field. In total, however, small depots still come to around 1.14% p.a. in total costs – the second-highest figure in our rating. Only from €50,000 does OSKAR approach the market average, at around 0.84% p.a. Scoring (20/32): The service fee of 1.0% p.a. at the entry level only just falls in the "≤ 1.00%" category and earns 4 out of 16 points. The very low product costs of 0.14% p.a. give the full 10 points. Since neither transaction costs nor a performance fee apply and depot management is free, there are the full 6 points for other costs.

OSKAR offers five risk levels, named after the equity share from OSKAR 50 to OSKAR 90. The portfolio combines shares with a safety component of bonds and gold – OSKAR 50, for example, with 50 percent shares and 50 percent bonds and gold. In contrast to most competitors in our rating, OSKAR thus covers more than two asset classes and diversifies worldwide. Allocation to the appropriate level is done via an investment questionnaire. On rebalancing, OSKAR is unusually transparent: the comparison does not take place at fixed time intervals but on demand and automatically as soon as the deviation from the target allocation exceeds six percent. This rule is publicly and comprehensibly documented. Scoring (25/25): Worldwide diversification across shares, bonds and gold meets the "several asset classes" criterion and earns the full 10 points. The questionnaire with five risk levels reaches exactly the required minimum number and gives the full 8 points. Automatic rebalancing with a publicly documented six percent threshold brings the full 7 points. OSKAR is thus one of two providers with a full score in this chapter.

This is where OSKAR shows its clearest weakness. The provider mainly communicates return expectations – for example 4.35% p.a. for OSKAR 50 and 5.78% p.a. for OSKAR 90 in the middle scenario. These are forecasts, not realised results. We could not find a continuous, publicly accessible after-cost track record per risk level over at least three years on the provider's pages; reliable long-term data comes mainly from third-party real-money tests. The investment strategy pages describe the portfolio structure by asset class, while a complete list of the funds used with ISINs is not publicly viewable before signing a contract. The cost side, by contrast, is clean: the fee scale and the product costs of 0.14% p.a. appear together. Scoring (11/18): Since OSKAR mainly publishes return expectations rather than a realised after-cost track record per risk level, we award only 4 out of 8 points for performance. For disclosure at asset class level without an ISIN list there are 3 out of 6 points. The joint presentation of the fee scale and product costs brings the full 4 points.

The minimum investment is €1,000. It does not apply, however, if a savings plan of at least €25 a month is set up instead – for savings plan investors, entry is therefore practically hurdle-free. We assess the formally stated minimum investment amount. There is no minimum term, and customers can access their balance at any time. Deposits, withdrawals and savings plan changes can be made directly in the app. We could not verify a freely selectable execution rhythm for the savings plan. Scoring (11/15): The minimum investment of €1,000 falls in the "≤ €1,000" level and earns 4 out of 6 points. The savings plan from €25 meets the minimum instalment, but a freely selectable rhythm is not documented – for that there are 3 out of 5 points. Since there is no minimum term and partial withdrawals are possible at any time, we award the full 4 points.

The depot is held at Baader Bank, based in Germany and subject to BaFin supervision. Customer securities are held as segregated assets. OSKAR thus meets the highest level of our security criterion. An app for iOS and Android is available and fully covers deposits, withdrawals and savings plan changes; there is also a web portal. Customer service can be reached by phone in German and scored well in an independent service comparison with 83.0 points. On Trustpilot, OSKAR has 4.6 stars from 4,214 reviews (as of September 2026), the highest number of reviews among the robo-advisors. Scoring (10/10): A German custodian bank (Baader Bank) and BaFin supervision give the full 5 points. An app for iOS and Android plus web portal bring the full 3 points. Phone advice in German gives the full 2 points.
