Tracking free trial end dates manually: the spreadsheet method

The 4-column spreadsheet setup that catches trial deadlines before they turn into a charge — plus where manual tracking usually breaks down.

The 4 columns you need

Service namewhat you signed up for
Trial start datethe day you signed up
Trial lengthe.g. 7, 14, or 30 days
Cancel-by datestart + length, minus 1–2 day buffer

Log it the day you sign up

Add the row immediately after signing up, while the terms are still in front of you — waiting even a day is how most trials get forgotten.

The trap to avoid

Watch out: A spreadsheet only works if you actually open it. Most manual trackers get forgotten within a few weeks, and there is no notification when a cancel-by date arrives.

Smartest move

Pair the spreadsheet with an actual reminder — a calendar entry or a free calculator that outputs a cancel-by date and a downloadable .ics file, so you do not have to remember to check the sheet.

Skip the spreadsheet math

Enter the trial start date and length — TrialGuard calculates the exact cancel-by date and gives you a one-click calendar reminder. Free, on-device.
