Conclusion
- I have mentioned some of the important metric formulas used in Google Analytics.
- Some of the metrics are not available in Google Analytics Default Reports. i.e in Audience, Acquisition, Behavior & Conversion Reports.
- You can use these metrics (used in formulas) by creating Custom Reports or via GA Reporting API.
- You can check the whole list of dimensions & metrics formulas here.
