AWS S3 Pricing Calculator

Estimate your monthly Amazon S3 storage and data transfer costs.

Understanding AWS S3 Pricing

Amazon Simple Storage Service (S3) is a highly scalable object storage service. Its pricing is based on several factors, primarily storage volume, the number and type of requests made to your buckets, and data transfer. This calculator helps you estimate these costs based on typical usage patterns.

Key Pricing Components:

  • Storage: Charged per GB stored per month. Different S3 storage classes (Standard, Intelligent-Tiering, Glacier, etc.) have different pricing. This calculator focuses on S3 Standard for simplicity.
  • Requests & Data Retrieval: You pay for requests made to your S3 buckets. There are two main types:
    • Write Requests: PUT, COPY, POST, LIST operations.
    • Read Requests: GET, SELECT, and other operations.
    Pricing is often per 1,000 or 1,000,000 requests.
  • Data Transfer:
    • Data Transfer Out to Internet: This is typically the most significant data transfer cost. Charged per GB transferred out.
    • Data Transfer IN from Internet: Generally free.
    • Data Transfer between AWS Regions: Charged per GB.
    • Data Transfer to CloudFront: Generally free.
  • Management & Analytics Features: Optional features like S3 Inventory, S3 Analytics, and Object Tagging incur additional costs. This calculator does not include these.

How the Calculation Works (Simplified for S3 Standard):

The estimated monthly cost is a sum of the costs for each component. We use representative pricing for the AWS US East (N. Virginia) region as of late 2023/early 2024. Note that prices vary by region and can change.

1. Storage Cost:

Storage Cost = (Storage GB / Month) * Price per GB per Month

Example Pricing (S3 Standard, US East N. Virginia): ~$0.023 per GB for the first 50 TB.

2. Request Costs:

PUT Request Cost = (PUT Requests / 1,000,000) * Price per 1M PUT Requests

GET Request Cost = (GET Requests / 1,000,000) * Price per 1M GET Requests

Example Pricing (S3 Standard, US East N. Virginia):

PUT Requests: ~$0.005 per 1,000 requests (or $5 per million)

GET Requests: ~$0.0004 per 1,000 requests (or $0.40 per million)

3. Data Transfer Out Cost:

Data Transfer Out Cost = (Data Transfer Out TB * 1024 GB/TB) * Price per GB Transferred Out

Example Pricing (S3 Standard, US East N. Virginia, first 10 TB): ~$0.09 per GB.

Total Monthly Cost = Storage Cost + PUT Request Cost + GET Request Cost + Data Transfer Out Cost

Use Cases:

  • Estimating costs for static website hosting.
  • Budgeting for application data storage.
  • Planning for data backup and archiving.
  • Understanding the financial impact of high-traffic applications using S3 for media storage.

Disclaimer: This calculator provides an estimate based on simplified assumptions and publicly available pricing. Actual costs may vary based on your specific usage, AWS region, chosen storage class, negotiated pricing, and other AWS services used in conjunction with S3. Always refer to the official AWS S3 pricing page for the most accurate and up-to-date information.
