S3 Bucket Cost Calculator

Managing cloud storage costs is a critical aspect of any business’s IT strategy. Amazon S3 (Simple Storage Service) is a popular choice for storing data in the cloud. To help you estimate the cost of using an S3 bucket, we’ve created an S3 Bucket Cost Calculator.


The cost calculation is straightforward:

  • Storage Cost: Multiply the data size (in GB) by the number of storage months and the cost per GB per month (which is $0.023 for standard storage).
  • Request Cost: Multiply the number of requests by the cost per request (which is $0.0000004).

The total cost is the sum of the storage cost and request cost.

How to Use

  1. Input the data size in GB.
  2. Input the number of storage months.
  3. Input the number of requests.
  4. Click the “Calculate” button to get the estimated cost.


Let’s say you have 100 GB of data that you plan to store in an S3 bucket for 12 months, and you expect 10,000 requests per month. Using the calculator:

  • Data Size: 100 GB
  • Storage Months: 12 months
  • Request Count: 10,000 requests

After clicking “Calculate,” the estimated cost will be displayed in the “Result” field.


  1. Q: What is Amazon S3?
    • A: Amazon S3 is a scalable object storage service provided by Amazon Web Services (AWS). It allows you to store and retrieve data, making it a popular choice for data storage in the cloud.
  2. Q: Is there a free tier for Amazon S3?
    • A: Yes, AWS offers a limited free tier for S3, which includes 5 GB of standard storage and 20,000 GET and 2,000 PUT requests per month for 12 months for new customers.
  3. Q: How is S3 pricing structured?
    • A: S3 pricing is based on the amount of data stored, data transfer, and the number of requests. The calculator here focuses on storage and request costs.
  4. Q: Can I change the storage class for my S3 objects?
    • A: Yes, you can choose from various storage classes in S3, each with different pricing. The calculator assumes standard storage pricing.
  5. Q: Are there any additional costs not covered by this calculator?
    • A: Yes, other costs such as data transfer, data retrieval, and data management may apply. This calculator focuses on basic storage and request costs.
  6. Q: Are there discounts for long-term storage?
    • A: AWS offers reduced pricing for long-term storage through S3 storage classes like S3 Infrequent Access and S3 Glacier.
  7. Q: How often should I update my cost estimates?
    • A: It’s a good practice to periodically review your storage usage and adjust your cost estimates accordingly.
  8. Q: Can I use this calculator for other AWS services?
    • A: This calculator is specific to estimating costs for an S3 bucket. Different AWS services have different pricing structures.
  9. Q: Does the calculator include taxes or additional fees?
    • A: No, this calculator provides a basic estimate of storage and request costs and does not include taxes or any additional fees that may apply.
  10. Q: Is there a way to optimize S3 costs further?
    • A: Yes, you can use lifecycle policies, object tagging, and other AWS features to optimize your S3 costs.


The S3 Bucket Cost Calculator is a handy tool for estimating the expenses associated with using Amazon S3 for your data storage needs. However, keep in mind that the actual costs may vary based on various factors such as data transfer, retrieval patterns, and additional AWS services used in conjunction with S3. Use this calculator as a starting point for cost estimation and consider consulting AWS documentation for detailed pricing information. Properly managing and optimizing your S3 usage can help you maximize the benefits of cloud storage while keeping costs in check.
