99% of customers don't notice it?

Too many self-employed people, businesses and private individuals have suffered a five-figure loss and some even much, much, much more due to FRAUD by banks and savings banks!

--> Incorrect and inflated calculations of loan and deposit interest rates as well as fees.

A very good report on this topic was published by ARD "The Red Giant Rips Off" on September 2, 2019.

NDR also published a good short report:
"Apparently billions in damage due to excessive interest rates", Hallo Niedersachsen – September 1, 2019

Please search for both videos on the internet and watch the reports.
After that you will be well informed and can check whether you too have suffered a five-figure or even larger loss.

Not all banks and savings banks cheat when calculating interest, but it is worth checking your interest calculations (loan interest + deposit interest) and bank fees.

Blind trust in banks and savings banks is, unfortunately, far too often unjustified.

For some readers the topic is new. Many years ago I recalculated interest (loan).
Between 20 and 75% was overcharged. These were the first three interest calculations from my bank at the time.
I brought it to my bank's attention.
Afterwards my former bank was able to enter the correct interest rate into their IT system…

Would you like to switch banks or open another free bank account?

 
Anyone who wants to find out more about excessive/incorrectly calculated loan interest rates, fees and the quality of bank advice should watch "The Banks' Tricks - Questionable Deals with Interest and Fees" by WISO (ZDF, September 12, 2014).
 
In the program "The Interest Trap - How Banks Rip Off Their Customers", ZDFzoom, October 30, 2013 a seven-figure loss is presented.
 
Also the interview (after approx. 10 min 42 sec) with a former senior employee of a bank is very interesting for bank customers.
