Clarification on EC2 pricing

Question

Hi all,  
  
I'd like to use an instance with lots of vCPUs to benchmark a specific test I'm running locally.  
Let's assume I chose a compute instance, like c5.9xlarge at 1.818$/hour (or even more vCPUs like c5.24xlarge).  
  
If I create the instance, launch it, download and install some software (like gcc) and use it for one hour, and stop it, I will only pay 1.818 USD ?   
Do I need to pay if the instance is down ? If not, how long will it be kept ?  
  
Thanks for your help.

Answer

Thanks Paul,  
  
So if I delete my instance, I'll only be charged for one hour I guess.

Answer

Hi martinjean,  
  
I believe if you do on-demand pricing you will only be charged the hour, but you will still be charged for any EBS volumes backing the VM (even if the VM is stopped).

Thanks

Answer

Correct.
