Subscription Cost Auditor
Audit every subscription in one place. Normalize weekly, monthly, and yearly bills, see cost-per-use, get a cancel-first ranking that flags your worst value, and download renewal reminders as a calendar file.
How to use this tool
- Add each subscription: name, amount, billing cycle, and roughly how many times you use it per month.
- Read the normalized monthly and annual totals at the bottom.
- Check the cost-per-use column and the red “cancel first” flag on your worst value.
- Click Download renewal reminders to export an .ics calendar of renewal dates.
- Copy the page URL to back up or share your audit — the list rebuilds from the link.
The classic r/personalfinance advice is “audit your subscriptions” — but the math is annoying: one bill is weekly, another yearly, and the real question isn’t the price, it’s whether you actually use it. This auditor solves both. It normalizes every plan to a common monthly and annual figure, then computes cost per use from how often you open each one.
The invented part is the cancel-ROI ranking: it scores each subscription by annual cost weighted against usage and flags the single worst offender as cancel first — the fastest dollar you can save. When you’re ready to act, one click exports an .ics calendar file with recurring renewal reminders (with a 2-day alarm) so a forgotten free trial never auto-charges you again. Your list is saved locally and encoded into the URL, so a shared link rebuilds the whole table.
Frequently asked questions
- How is cost-per-use calculated?
- The tool normalizes each subscription to a monthly cost, then divides by how many times you said you use it per month. A $15/month app used twice costs $7.50 per use; the same app used 30 times costs $0.50 per use. Subscriptions with zero uses are flagged as “unused.”
- What does the .ics download do?
- It generates a standard calendar file with one recurring event per subscription, set to its billing cadence, with a reminder two days before renewal. Import it into Google Calendar, Apple Calendar, or Outlook so you review (and can cancel) before each charge.
- Is my subscription list private?
- Yes. It is stored only in your browser’s local storage and encoded into the page URL. Nothing is sent to a server. If you don’t want to share the data, simply don’t share the URL.
