Cloud Storage Cost Calculator

Calculate cloud object storage expenses (AWS S3, Google Cloud Storage, Azure Blob), modeling hot, infrequent access (cool), cold, and deep archive tiers, API requests, and retrieval fees.

5,000 GB = 5 TB

Calculated Cloud & Storage Breakdown

Cloud Object Storage Pricing Formula

Total Monthly Cost = (Stored GB * Rate) + (PUT Ops / 10,000 * PutRate) + (GET Ops / 10,000 * GetRate) + (Retrieval GB * RetrievalRate)
  • Storage Tiers: Hot (~$0.023/GB), Cool/Infrequent (~$0.0125/GB), Cold/Glacier (~$0.004/GB), Deep Archive (~$0.00099/GB).
  • Write/PUT Operations: API operations to upload, copy, or list objects ($0.05 per 10k).
  • Read/GET Operations: API requests to download or inspect objects ($0.004 per 10k).
  • Data Retrieval Fees: Surcharges applied per GB accessed from cool, cold, or archive storage tiers.

Step-by-Step Worked Example

Scenario: A company stores 5,000 GB (5 TB) in AWS S3 Standard (Hot) storage at $0.023/GB, executing 20,000 PUT requests ($0.05/10k) and 100,000 GET requests ($0.004/10k).

Calculation Steps:

  1. Storage Subtotal: 5,000 * $0.023 = $115.00/month
  2. PUT Operations: (20,000 / 10,000) * $0.05 = $0.10/month
  3. GET Operations: (100,000 / 10,000) * $0.004 = $0.04/month
  4. Total Monthly Cloud Storage: $115 + $0.10 + $0.04 = $115.14/month
  5. Annual Cloud Storage Cost: $115.14 * 12 = $1,381.68/year
Result: Total cloud storage cost is $115.14/month ($1,381.68 annually) at an average cost of $0.023/GB.

How to Use This Calculator

  1. 1Select your cloud storage lifecycle tier (Hot, Cool/Infrequent, Cold/Glacier, or Deep Archive).
  2. 2Enter the total gigabytes of data to be stored.
  3. 3Input expected monthly read (GET) and write (PUT) API transaction counts.
  4. 4Add estimated data retrieval gigabytes if evaluating cooler tiers.

Assumptions & Limitations

  • Rates benchmarked against US East standard public cloud pricing.
  • Outbound internet data transfer (egress) is calculated separately.

Frequently Asked Questions

What is the risk of using Deep Archive cloud storage?

While deep archive is extraordinarily cheap ($0.00099/GB or ~$1/TB/month), retrieving data can take 3 to 12 hours and incurs significant data retrieval fees. It is strictly meant for regulatory compliance archives that may never be accessed.

Why are API operations charged separately in cloud storage?

Cloud providers charge for the transactional compute load of indexing and cataloging billions of individual objects. Applications that write millions of tiny 1 KB files often end up paying more for API calls than for raw gigabytes.
