• Charges varies upon AMIs backed and storage VOLUMS.
• AMIs backed by instance storage charged for: AMI storage + Instance usage
• AMIs backed by Amazon EBS storage charged for: Volume storage + Usage in addition to the AMI + instance usage
• When an Amazon EBS-backed instance is stopped, you are not charged for instance usage, but you are STILL charged for volume storage.
• AWS charges a full instance hour for EVERY transition from a stopped state to a running state, even if we transition the instance multiple TIMES within a single hour.

For example: if hourly instance charge for your instance is $0.10 and if you were to run that instance for one hour without stopping it, you would be charged $0.10. If you stopped and restarted that instance twice during that hour, then you would be charged $0.30 for that hour of usage (the initial $0.10, PLUS 2 x $0.10 for each restart).
