Banking strategies in Germany: Managing multiple accounts and interest rates

In Germany, consumers are increasingly utilizing multiple bank accounts to optimize their finances, a trend driven by the ease of combining products from different providers. While having several accounts can help separate household expenses, manage specific budgets, or provide a technical reserve in case of service disruptions, it carries the risk of becoming overly complex if responsibilities are not clearly defined.

A study by FMH-Finanzberatung highlights the potential financial benefits of 'interest rate shopping' with daily savings accounts (Tagesgeld). The study compared three strategies using a 50,000 Euro starting capital over four years: a consistent switcher, a direct bank customer, and a traditional branch bank customer.

The results showed that a consistent switcher earned 6,744 Euro in interest, whereas a branch bank customer earned only 797 Euro. This represents a difference of 5,947 Euro. To achieve this, the switcher performed 16 bank changes and opened 17 accounts, moving whenever a rate advantage of at least 0.5 percentage points was available. However, experts note that frequent changes can impact credit scores (Schufa) and that many promotional rates are tied to opening additional checking accounts or brokerage portfolios.
