Find every subscription hiding in your bank statement.

Export a CSV from your bank or card, drop it here, and get a list of every recurring charge: what it costs a year, which prices went up, which ones stopped, and when each renews next.

How do I get a CSV from my bank?
  1. Sign in to your bank or card website on a computer.
  2. Open the account, then look for Download, Export or Statements.
  3. Pick CSV (sometimes called Excel or spreadsheet format) and the longest date range offered. Twelve months catches yearly renewals; three months is the minimum for monthly ones.
  4. Drop the file above. Overlapping downloads are merged without double counting.
