The contract auto-renews in three days — and nobody knows if the cancellation will still arrive in time. Deadlines hide in the fine print, Word shifts the address field, and the subscription runs another year.
The Termination Workbench computes the deadline and builds the letter to DIN 5008 — ready to post.

German contracts — gym memberships, phone plans, insurance policies, subscriptions — typically renew automatically unless you cancel in time. The cancellation notice is called a Kündigung, and the notice period is the Kündigungsfrist. The rule that surprises most newcomers: the deadline refers to the day your letter arrives at the provider (Zugang), not the day you send it. A three-month notice period on a contract ending 31 December means your Kündigung must be in the provider's hands by 30 September. To work out your own deadline, you need three details from the contract: the start date, the term length, and the notice period — then count backwards from the end of the term and allow generously for postal delivery. Miss the cut-off, and a renewal clause can extend the contract by months or another full year. For many newer consumer contracts, monthly cancellation is possible after the initial term, but whether that applies to yours depends on the contract type and signing date — the fine print decides.
Many consumer contracts can now be cancelled in Textform — text form, such as e-mail, without a handwritten signature. Employment contracts and residential leases, however, still require Schriftform: a paper letter with your handwritten signature. Your contract's cancellation clause states which form applies; when unsure, send a signed letter, which satisfies both standards. Since you may later need to prove your notice arrived on time, the usual German practice is registered mail, an Einschreiben. The Einwurf-Einschreiben — where the carrier documents dropping the letter into the mailbox — is generally the practical choice. The hand-over variant (Übergabe-Einschreiben) can backfire: if nobody is home and the letter is never collected, delivery may not count. Keep the posting receipt and ask the provider for written confirmation of the cancellation.
In certain situations you may terminate a contract extraordinarily, without waiting for the regular notice period. Typical triggers are price increases on energy or telecom contracts, a move to a place where the provider cannot deliver the service, or premium increases on insurance policies. The conditions differ by contract type, and the window to act is usually short. If you have such a reason, act quickly, label the letter explicitly as a Sonderkündigung, and state the reason — otherwise it may simply be treated as a regular cancellation at the next possible date.
The Kündigungs-Werkbank handles both halves of the task. Its deadline calculator (Fristenrechner) determines the Stichtag — the last day your notice may arrive at the provider — so you are not reconciling fine print and calendar by hand. At the same time, it builds the cancellation letter to DIN 5008, the German business-letter standard: the address sits at the standard position, the layout fits a window envelope, and the letter looks the way German providers expect. After free registration, the tool is free to use — a real advantage when a contract would renew in a matter of days.

Find three details in your contract: the start date, the term length, and the Kündigungsfrist (notice period). Count backwards from the end of the term to find the cut-off date — your cancellation must have reached the provider by then, and arrival (Zugang) is what counts, not the sending date. The deadline calculator of the Kündigungs-Werkbank determines this cut-off date for you.
Often yes: many consumer contracts can be cancelled in Textform, which includes email. However, employment contracts and residential leases still require Schriftform — a paper letter with a handwritten signature. Check your contract's cancellation clause; if in doubt, send a signed letter, which satisfies both requirements and is easier to prove in a dispute.
It is the standard advice in Germany, because you may need to prove the notice arrived on time. The Einwurf-Einschreiben, where the carrier documents dropping the letter into the mailbox, is usually the practical choice. The hand-over variant can fail if nobody accepts the letter. Keep the posting receipt and ask the provider for written confirmation of the cancellation.
A special termination right that lets you cancel a contract outside the regular notice period in defined situations — typically price increases on energy or telecom contracts, a move to an address where the service cannot be provided, or premium increases on insurance. Conditions depend on the contract type, and the time window is usually short, so act promptly.
Yes. The Kündigungs-Werkbank is a free browser tool by AURIFEXA. After free registration, it calculates the exact date by which your cancellation must reach the provider and builds the letter to DIN 5008, the German business-letter standard, so it fits a window envelope and looks the way German companies expect. It does not replace legal advice.
