The actual calculator in action, for a developer role: https://about.gitlab.com/roles/engineering/developer/

I have some trouble following their rent index by region approach, described in some more detail here: https://about.gitlab.com/handbook/people-operations/global-c...

For example for Germany, the calculator still only list four major cities and an "Everywhere else" option, which has an extremely low index. I also couldn't find the raw results of their region analysis.
