Size of hosted service related to number of features and extent.

[AleydisG__Pere]

Is the size of an AGOL hosted feature service dependant on the number of features in it or its extent?
The credits estimator stands that the average size used in this calculation is 1.5MB per feature service, but what would that service contain? To estimate the size of my feature services I need some more information. For example, I have 5000 features in a 4 square km extent. What size would my feature service have?

Thank you!

Thinking in terms of a having my own ArcGIS Server and corporative database, I've tried using my MXDs size and database size to estimate the feature services storage size in AGOL. My sql server database size is about 3Gb and my 46 MXD/map services size is 51Mb. That makes about 750 credits. I don't know if my deductions are right, but the total amount of credits sounds more realistic to me than the 132 credits estimated with the Service credit estimator.

Any other ideas are welcome.
