+## Costs
+
+You are responsible for the cost of the AWS services used while running this guidance. If you haven't used Systems Manager Session Manager in your AWS account before, it will be the only additional cost associated with using SageMaker SSH Helper. The costs of [SageMaker resources](https://aws.amazon.com/sagemaker/pricing/) do not change and you pay only for the resources that you use.  
+
+As explained in the [IAM and SSM configuration](IAM_SSM_Setup.md), you need to enable Advanced instances tier in Systems Manager because this is the only way to enable Session Manager and access remote instances interactively with SSM and SSH. As of June 2024, the advanced instances tier comes at [a small fee](https://aws.amazon.com/systems-manager/pricing/#Session_Manager), which is $0.00695 per advanced on-premises instance per hour. 
+
+See [the sample cost breakdown table](Sample_Costs.md) for SageMaker and Systems Manager for AWS account that runs the routine [CI/CD tests](tests/) for this guidance in the EU (Ireland) Region.
+
+We recommend creating a [Budget](https://docs.aws.amazon.com/cost-management/latest/userguide/budgets-managing-costs.html) through [AWS Cost Explorer](https://aws.amazon.com/aws-cost-management/aws-cost-explorer/) to help manage costs. Prices are subject to change. For full details, refer to the pricing webpage for each AWS service used in this guidance.
