If you stop or terminate the Spot Instance |
Windows and Linux (excluding RHEL and SUSE) | Charged for the seconds used | Charged for the seconds used |
| RHEL and SUSE | Charged for the full hour even if you used a partial hour | Charged for the full hours used, and charged a full hour for the interrupted partial hour | |

Charged for the full hours used, but no charge for the interrupted partial hour |
EBS volume usage
While an interrupted Spot Instance is stopped, you are charged only for the EBS volumes, which are preserved.
With EC2 Fleet and Spot Fleet, if you have many stopped instances, you can exceed the limit on the number of EBS volumes for your account.
