Build a Simple Subscription Tracker With Renewal Reminders

Use a spreadsheet to keep the facts and a calendar to prompt a decision. A renewal date in a cell does not automatically send a reminder. Record the provider’s cancellation deadline separately so the alert arrives while you can still act.

Start with subscriptions you already have. This guide organizes information; it does not cancel services, change billing or guarantee that an alert will arrive.

1. Build one row per subscription

Use these column headings in a blank spreadsheet:

Service / account hint / currency / charge per cycle / cycle in months / next charge date / cancellation deadline / decision reminder / billing provider / status / last checked.

Use a non-sensitive account hint, such as “personal email,” rather than a password or full card number. Keep the file private, and avoid public sharing links. Separate currencies instead of adding US and Canadian dollars as though they were identical.

Find the current charge and next date in the service’s billing page or receipt. Check whether billing is handled directly, through an app store or by another provider. That affects where you manage the subscription.

2. Separate the charge from the decision

The next charge date is not necessarily the last day to cancel. Read the applicable terms and record any deadline or notice period. If the rule is unclear, mark it “verify” rather than guessing that cancellation the day before is sufficient.

Choose a decision reminder earlier than that deadline, allowing time to sign in and resolve a problem. A trial also needs its own verified end date; do not assume every trial lasts a month.

Record the billing page’s official address if useful, but avoid storing links containing login tokens. After a cancellation, retain the confirmation and check what the provider says about access and further charges. Removing the reminder alone does not cancel anything.

A copyable example with monthly equivalents

These invented services and amounts illustrate the structure, not current prices or actual cancellation rules:

• Music Example: USD 12 each month; next charge December 10; deadline marked “verify”; decision reminder December 3.
• Cloud Example: USD 60 every 12 months; next charge February 1; deadline marked “verify”; decision reminder January 15.

If column D is the charge per cycle and E is the cycle length in months, =D2/E2 gives a monthly equivalent: 12 for the first example and 5 for the second.

The combined equivalent is USD 17 per month, but the cash charges still arrive as USD 12 monthly and USD 60 annually. Keep the next actual charge visible; an average does not describe next month’s bill. Use this simple formula only for monthly or annual cycles represented correctly in months, and handle irregular billing separately.

3. Put the reminder in a calendar you check

For a concrete example, Google Calendar on a computer supports repeating events. Create an event on your chosen decision date, give it a title such as “Review Cloud Example renewal,” and add a note with the verified deadline and billing provider.

Choose the repeat frequency from the event’s “Does not repeat” menu only if the pattern is appropriate. Annual billing usually needs an annual review, not a monthly duplicate. Add a notification or email reminder in the event and save.

Google documents separate notification settings for events and all-day events. Check the actual event, account and calendar rather than assuming an existing default covers it. A desktop browser alert also depends on permissions and Calendar being open; use the device and delivery method you rely on.

Create a harmless test event a few minutes ahead and confirm that its alert arrives. A successful test helps check the setup; it does not guarantee every future notification. Keep a regular manual review as a backup.

4. Maintain the next date after a decision

1. Sort the sheet by the next decision reminder.
2. Open each due service’s official billing page.
3. Choose whether to keep, change or cancel it yourself.
4. Update the charge, deadline, status and last-checked date.
5. Move or remove the calendar reminder to match the result.

Calendar recurrences do not automatically track changes to provider billing dates or prices. Review them when a service sends a notice or you change its plan. For a wider planning routine, see turn loose notes into a weekly plan.
