Is there a way to display a calculated field in a custom report, for example I want to display the value of (event X / event Y) over time? (including average event value, total events, etc.)

No, I don't think that Google Analytics offers calculated fields yet. You'll need to extract your data via the reporting API, then manipulate it using Excel or a database.

If you don't want to write code to use the API directly, there are tools available that you can use to extract your data: For example, Excellent Analytics, is a free tool for downloading Analytics data into Excel.

  • Thanks, too bad this simple feature isn't supported by Google analytics. Will check out Excellent Analytics

  • I just read this comment, watched the video on this page and built the report that I was looking for within 15 minutes, it's pretty simple. Link: developers.google.com/analytics/solutions/…

For anyone that stumbles upon this question, Google Analytics now offers Calculated Metrics.
