You will be charged an upfront fee for each CloudHSM instance you launch, and an hourly fee for each hour thereafter until you terminate the instance. If you want to try the CloudHSM service for free, you can request a two week trial. Please review our Free Trial page for eligibility information.
** Bills are presented monthly. Since different months have different numbers of days, the amount that you see on your bill will vary slightly.
Each partial instance-hour consumed will be billed as a full hour. Amazon reserves the right to charge for network data transfers in and out of a CloudHSM that exceed 5000 GB per month at a rate of $.02 per GB.
