How this calculator works

Ballpark monthly AWS spend from compute, storage, and egress. Planning estimates only — verify with production tools and vendor pricing where applicable. Monthly = (instances × $/hr × 730) + storage GB × $/GB + egress GB × $/GB. Example: 2 × t3.large ($0.08/hr) + 500 GB S3 + 100 GB egress → ~$140/mo.

Monthly = (instances × $/hr × 730) + storage GB × $/GB + egress GB × $/GB.

Example: 2 × t3.large ($0.08/hr) + 500 GB S3 + 100 GB egress → ~$140/mo.

When to use this AWS Pricing & TCO

Common use cases

  • Ballpark monthly AWS spend from compute, storage, and egress.
  • Sanity-check with this case: 2 × t3.large ($0.08/hr) + 500 GB S3 + 100 GB egress → ~$140/mo.
  • The relationship is: Monthly = (instances × $/hr × 730) + storage GB × $/GB + egress GB × $/GB.

Localized examples

  • Cloud Computing & AI Tech: the example on this page uses the same formula as the widget.

What you get

  • Fields: EC2 instances, Avg $/instance/hour, Storage (GB), Storage $/GB/mo
  • Monthly = (instances × $/hr × 730) + storage GB × $/GB + egress GB × $/GB.
  • Example on the page: 2 × t3.large ($0.08/hr) + 500 GB S3 + 100 GB egress → ~$140/mo.

How to Calculate AWS Pricing & TCO Step-by-Step

  1. 1Enter EC2 instances, Avg $/instance/hour, Storage (GB), then the remaining fields. Use the values you have, not a catalog average, unless that is all you know.
  2. 2Monthly = (instances × $/hr × 730) + storage GB × $/GB + egress GB × $/GB.
  3. 3Worked case: 2 × t3.large ($0.08/hr) + 500 GB S3 + 100 GB egress → ~$140/mo.
  4. 4Compare the result to last month’s invoice or a vendor calculator before you commit capacity.

Governing formula

Monthly = (instances × $/hr × 730) + storage GB × $/GB + egress GB × $/GB.

2 × t3.large ($0.08/hr) + 500 GB S3 + 100 GB egress → ~$140/mo.

Example: set EC2 instances = 2, Avg $/instance/hour = 0.08, Storage (GB) = 500, then read the result.
