Cloud Cost Estimator (AWS, Azure, GCP)

Calculate cloud compute and storage bills for AWS, Azure, and GCP with transparent rates and live updates.

How to Use This Calculator

This calculator helps engineering and finance teams estimate cloud bills by combining compute hours and storage usage with the published hourly and per-gigabyte rates for AWS, Azure, and GCP.

Choose your provider, enter the number of hours of compute each month, and add storage in gigabytes. The widget multiplies the usage by the provider-specific rates to deliver a single monthly cost total within the results card.

Methodology: The tool uses a fixed rate lookup for each provider and a deterministic, two-decimal rounding strategy to keep the output predictable. Usage and storage values are validated to ensure they are non-negative and finite before computation.

Interpretive Guide

  • Compute costs are calculated by multiplying usage hours by the provider's hourly rate.
  • Storage costs are simply storage gigabytes multiplied by the provider's rate per GB.
  • The monthly total shows both costs together so you can compare providers quickly.

FAQs

How accurate is this calculator?

This calculator uses the most current published pricing data for each provider, but always verify with the provider's official pricing page before budget approval.

Can I use this for multiple regions?

Regional pricing can vary. This estimator reflects a default global rate per provider—check the provider's pricing calculator for regionally specific estimates.

The Formula Explained

Monthly Cost = (Usage Hours × Rate per Hour) + (Storage GB × Rate per GB)

Glossary of Terms

  • Cloud Provider: The service provider for cloud resources.
  • Usage Hours: Total hours of cloud resource usage.
  • Storage GB: Amount of storage used in gigabytes.

How It Works: A Step-by-Step Example

Let's assume you're using AWS for 100 hours of compute and 50 GB of storage.

Apply the formula: Monthly Cost = (100 × $0.10) + (50 × $0.023) = $10 + $1.15 = $11.15

Frequently Asked Questions
