About these tools

CloudWebSchool tools are educational aids to help you plan and understand cloud costs before committing to a workload. They are not billing forecasts, quotes, or invoices. Always verify estimates with the official AWS pricing documentation and the AWS Pricing Calculator before making financial decisions.

More AWS tools are planned, including calculators for Lambda, RDS, and S3.

Pricing data

Pricing constants in these tools are sourced from official AWS documentation and reviewed periodically. Cloud pricing changes over time — always check the official AWS pricing pages for the most current rates.
