Cloud Cost Calculator

Estimate your monthly cloud spend across AWS, Azure, GCP, and Alibaba Cloud with the CloudCost calculator.

Cloud Cost Calculator

The CloudCost calculator helps you estimate the monthly cost of a given workload across the four major cloud providers. Rather than reading four separate pricing pages, you enter your instance, storage, and egress requirements once and see the side-by-side total.

How It Works

The calculator uses published on-demand list prices for the baseline US regions and applies the standard 1-year No Upfront reserved discount for steady-state workloads. You can toggle between on-demand and reserved to see the commitment savings, and switch regions to see how the same workload changes by geography.

Sample Workload

The table below shows a representative small web application: 4 general-purpose VMs, 500 GB of standard object storage, and 100 GB of outbound data transfer per month.

ComponentSpecificationAWS (us-east-1)Azure (East US)GCP (us-central1)
4 × general-purpose VM2 vCPU, 8 GiB each$277 / month$277 / month$180 / month
500 GB standard storageobject storage$11.50 / month$9.00 / month$10.00 / month
100 GB egressinternet transfer$9.00 / month$9.00 / month$0.00 (free tier)
Total on-demand$297.50$295.00$190.00
Total 1-yr reserved$179 (-40%)$176 (-40%)$133 (-30% SUD)

In this sample, GCP wins decisively thanks to per-second billing, sustained-use discounts, and the 200 GB free egress tier. AWS and Azure come within $3 of each other on reserved pricing, so the choice between them would be driven by tooling and licensing rather than raw price.

Using the Calculator

The full interactive calculator (selecting instance family, region, and commitment level) is being rolled out as a progressive web app. For now, use the comparison tables on the AWS, Azure, GCP, and Alibaba Cloud provider pages to assemble your estimate, and combine with the reserved instances and spot instances guides to apply the right discount.
