I have a set of feature classes in our organization that I wish to publish to ArcGIS Online.  I need to be aware of the Data Storage Credits that will be consumed in ArcGIS Online for the storage of these feature classes as hosted feature services.  I am noticing that the amount of data storage for a given feature service in AGOL is on the order of 2.8 times greater as compared to the amount of disk space consumed in a File Geodatabase.  For example, I have a feature class that requires 38 Mbytes in a File Geodatabase and 88 Mbytes in a Personal Geodatabase.  When the same feature class is published to ArcGIS Online as a feature service, the amount of data storage required is being reported as 106 Mbytes.

If one has their set of feature classes in a File Geodatabase, is there a method of estimating the amount of data storage needed to store these same feature classes as feature services in ArcGIS Online?

HI William,

The reported storage size that you see for hosted feature storage in ArcGIS Online is the actual size of the uncompressed data in the database. This can vary significantly depending on the data that you are publishing. Things that affect the size include geometry complexity (verticies), number of attributes, number of records, etc.There is no foolproof way to estimate this based on file geodatabase size.

The most accurate way to estimate the data size is to publish the data in ArcGIS Online and view the size. As feature storage is charged based on the amount of feature storage data you have in your organization hourly, the charges will insignificant if you decide it is larger than you want to store ( 0.32 credits to store GB of data for an hour)

Keep in mind that the storage size could change if the data is being edited after it's published. Check out this blog to find out more about monitoring feature storage in ArcGIS Online :  https://blogs.esri.com/esri/arcgis/2016/12/15/71673/
