Free Cloud Cost Calculators and Price Comparisons

Estimate data-transfer bills across AWS, GCP, Azure, Cloudflare and Bunny, compare S3, R2, Wasabi and Backblaze B2 storage plus egress, find the month owning a server beats renting cloud VMs, and work out when a reserved instance or savings plan pays for itself. Use them before a migration, a renewal or a budget review.

Each calculator lists the rates it uses and the date they were checked, so you can see exactly where a number comes from. Your usage figures stay in the browser — no signup, no sales call. They suit engineers sizing a migration, finance teams checking a forecast, and founders comparing hosting bills before a renewal.
