Calculate when your trial ends and set reminders before you get charged
Enter your trial start date and the number of free trial days. The calculator adds the trial duration to the start date to find your exact trial end date. It also shows a recommended cancel-by date (based on your chosen safety buffer) so you have time to act before the trial converts to a paid subscription.
Free trials automatically convert to paid subscriptions when they expire — and most people forget to cancel in time. Setting a reminder 3–7 days before the trial end date gives you enough time to evaluate the service and cancel if you decide it is not for you.
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.
