Answers: I won't have time to look up a reference, but all ebs usage is prorated per hour at least, if not per second. So when you delete an ebs volume, the create another one, you would at the worst be charged one hour double (the hour you did it in), at best have a couple of minutes of free tier left over. Note that instance deletion may or may not include ebs volume deletion, its configurable. All free tier assignments are done at billing level, so you can also run double the disk size for half a month and be still under free tier

Answers: John Humphreys
Body: <p>Can I delete an EC2 instance and start off from scratch on my EBS free tier usage? For instance, I was running a Red Hat server with 10 GB of EBS being used. However, I deleted that EC2 within a few hours. I then spun up another machine with 8 GB of EBS. Do I now have 22 GB of storage left for the month or just 12 GB, after combining the 8 with the 10?</p>
  
  <p>I assume, given that AWS doesn't reference hourly usage on their free tier category for EBS that the 30 GB is just a flat fee. Again, I simply don't understand if I can replete an instance, then start from scratch to zero EBS on a new instance.</p>
