What this calculator does
Many contracts — from online purchases to timeshares and loans — include a cooling-off period that lets you cancel penalty-free within a set number of days after signing. This online calculator adds that window to your agreement date to give you the exact last day you can cancel.
Worked example
You sign a distance-selling contract on July 8, 2026, which carries the standard14-day cooling-off period. Adding 14 days gives a cancellation deadline ofJuly 22, 2026.
Common mistakes
- Assuming every contract has the same cooling-off length. Periods range from a few days to a month depending on the type of agreement and jurisdiction — always confirm the exact figure in your contract.
- Miscounting the start day. Whether day one is the signing date or the day after varies by law and contract — a one-day error can mean missing the deadline entirely.
- Cancelling verbally instead of in writing. Most cooling-off rights require written cancellation (letter or email) sent within the window — a verbal notice alone is often not sufficient proof.
