Editorial and corrections policy

One day late, and a cancellation takes effect a month later. A period under the old rules, and a contract runs for another year. Here is how we avoid such mistakes.

Responsibility

Radif Partners answers for every period, amount and sentence in the templates. Report a discrepancy to contact@vorlagenrechner.de; we check it against the statute.

Official sources only

Rules come from the statute text, the base rate from the Bundesbank, points of interpretation from rulings of the Federal Court of Justice. Nothing is copied from a provider or another template site.

Simplifications, always stated

Municipal holidays are not included, and latest receipt dates are counted cautiously. Both are stated with the results and on the method page.

Checks before publication

Every build recalculates periods, interest and amounts against expected values and generates every template with default values; a mismatch stops publication.

Changes

When a provision or the base rate changes, we update the values by hand. The date of each figure is on the method page.

Independence

No business link with any landlord, employer, provider or law firm. Any such link would be stated in the text.
