What are you charged for?
- you are charged for a running instance at the @@instance price rates;
- ephemeral storage/instance-specific storage is included within that.
- when you stop an instance, you are charged at disk-space rates for
the stopped disk;
- when you create a volume, you are charged for that volume until you delete
it;
- when you create a snapshot, you are charged for that snapshot until you
delete it.
To make sure you’re not getting charged, go to your Instance view and
clear all search filters; anything that is “running” or “stopped” is
costing you. Also check your volumes and your snapshots - they should be
empty.
