Which AWS service or feature can be used to estimate costs before deployment?

Explanations:

The AWS Free Tier allows users to use certain AWS services for free, but it does not provide cost estimates for future deployments. It is more of a promotional offering than a cost estimation tool.

The AWS Pricing Calculator is specifically designed to help users estimate the costs of AWS services based on their anticipated usage, making it the ideal tool for estimating costs before deployment.

AWS Billing and Cost Management provides insights into actual costs and usage after services have been used, but it does not help in estimating future costs prior to deployment.

The AWS Cost and Usage Report provides detailed information about AWS resource usage and costs after the fact, which is not useful for estimating costs before the infrastructure is provisioned.
