Estimate your trial end date and download reminders for your own calendar
Enter your trial start date and trial length in days. The calculator adds that many calendar days to estimate an end date, then subtracts your chosen buffer for a suggested cancel-by date. For example, 14 days after September 1 is September 15. Confirm the actual deadline and time zone with your provider. This tool does not check or cancel your subscription.
Some free trials renew as paid subscriptions under the provider's terms. A reminder can help you review those terms before deciding whether to continue. Download the .ics file and import it into your own calendar, then check its notification settings. The calendar app delivers notifications; downloading a file does not cancel a subscription.
You can use this calculator for any subscription service that offers a free trial — streaming, software, cloud storage, news, fitness apps, productivity tools, and more. Just enter the service name, trial start date, and trial length.
This tool is for informational purposes only. Trial length, renewal dates and pricing differ by provider, so always confirm the exact dates and charges with the service you subscribe to. Calendar notifications are delivered by your own calendar app after you import the file — KirokuKit does not guarantee delivery or contract terms.
