Will I be charged while the EC2 is in stopping status?

Question

Recently one of my EC2 encountered a problem and becomes unavailable.  I stopped it and it takes about 1 hour to complete with a stopping status.  I'm wondering whether I will be charged the expense during this time period.

One more question, as this is the EC2 life cycle:
Start ACTION -> Health Check 1/2 In-progress -> Health Check 2/2 OK -> Running -> Stop ACTION -> Stopping -> Stopped.
What is the checkpoint regarding the expense charging?  From when to when?

Thank you!

Accepted Answer

The billing Period ends in the hour when the instance transitions into the stopping state. 
- enter stopping state at 55min you pay 1h
- enter stopping state at 65min you pay  2h

Answer

I'd like to note, since we launched per-second billing for EC2: https://aws.amazon.com/blogs/aws/new-per-second-billing-for-ec2-instances-and-ebs-volumes/ in the second example you are charged only for 1h 5min (instead of 2h) for instances to which per-second billing applies.
