1. What is AWS Cost Estimation?

AWS Cost Estimation helps predict the monthly costs of running your infrastructure on Amazon Web Services. It sums up the costs of individual services to provide a total estimate.

2. How Does the Calculator Work?

The calculator uses the simple summation formula:

Where:

• \( EC2 \) — Elastic Compute Cloud instances cost
• \( S3 \) — Simple Storage Service cost
• \( RDS \) — Relational Database Service cost
• \( Lambda \) — Serverless function cost

Explanation: The equation simply adds up the costs of all AWS services you plan to use to give a total monthly estimate.

3. Importance of Cost Estimation

Details: Accurate cost estimation helps with budgeting, prevents unexpected bills, and allows for cost optimization before deployment.

4. Using the Calculator

Tips: Enter costs for each service in USD. You can get individual service estimates from the AWS Pricing Calculator before using this tool.
