The articles on this blog answer a simple question: what does something really cost? Each piece first gives an overview of the prices and then explains what makes up the price, which additional costs arise and how you can save. Read the price table at the start as a guide and the following sections as help in applying the figures to your own situation. Where prices depend on where you live, on the plan or on the platform, we point this out explicitly.
The topics range from everyday life and subscriptions through cars, housing and energy to public authorities, health and finance. What all the articles have in common is the logic of the calculation: we show worked examples with transparent assumptions so that you can repeat the calculation with your own figures. In addition, kosten.org offers cost calculators and comparison pages that present the same topics interactively.
As far as possible, we take prices and fees from the providers' own pages or from official sources such as laws, ordinances and publications by federal authorities. Third-party sites and forums serve at most as a hint that something needs to be checked. Because providers change their tariffs, every article carries a modification date. When we have checked or adjusted a price, this date is updated, and the overview above sorts the articles accordingly.
Despite this care, things can change between two checks. The price the provider shows you at checkout before you conclude a contract is therefore always the one that counts. Our articles do not replace individual legal, tax or financial advice; for bigger decisions it is worth talking to an advice centre or a professional.
Never compare only the monthly price. Check whether a price is stated net or gross, whether it applies with annual payment and how long the minimum term is. Convert one-off costs such as connection fees, deposits or shipping into an annual figure, and consider when an offer switches automatically to a more expensive plan. This lets you compare offers with different pricing models fairly.
With subscriptions, also look at notice periods and the way you cancel. For consumer contracts concluded online, the German Civil Code requires an easy-to-find cancellation option. Anyone who enters cancellation dates in a calendar avoids unwanted renewals. A similar point applies to loans and financial products: the effective annual rate and the total cost in euros say more than a single interest rate.
When we rate providers or products, we describe transparently which criteria we apply and where the information comes from. We do not give our own awards such as winner labels and leave the choice to you. Some pages contain partner links through which we may receive a commission; this affects neither the prices for you nor the content of the articles, and such links are marked with an asterisk (*) and explained in a note on the page in question.
Mistakes can happen. If you notice an outdated price or an unclear statement, we welcome a note through the contact form. We check the report against the provider's page or the official source and correct the article as soon as the information is confirmed.
