Understanding AWS S3 Pricing
Amazon Simple Storage Service (S3) is a highly scalable, durable, and secure object storage service. Its pricing is based on several factors, and understanding these components is crucial for optimizing costs. This calculator helps estimate your monthly AWS S3 expenses based on typical usage patterns.
Key Pricing Components:
Storage: This is the primary cost component, determined by the amount of data stored (in GB) and the storage class you choose. Different storage classes offer varying levels of durability, availability, and retrieval times, with corresponding price differences.
Requests and Data Retrieval: You are charged for the number and type of requests made to your S3 buckets. There are generally two categories:
Requests that write data (PUT, COPY, POST, LIST)
Requests that read data (GET, SELECT, and others)
Retrieval fees also apply to certain infrequent access or archive storage classes, especially for expedited retrievals.
Data Transfer:
Data Transfer OUT to Internet: This is a significant cost factor. When data is transferred from S3 to users or applications outside of AWS, you are charged per GB.
Data Transfer to AWS Services: Data transfer between S3 and other AWS services within the same region is typically free. Data transfer between S3 and services in different regions incurs costs.
Data Transfer IN from Internet: Ingress (data coming into S3) is generally free.
Management Features: Optional features like S3 Inventory, S3 Analytics, and S3 Object Tagging might incur additional small charges. This calculator focuses on the core storage, request, and data transfer costs.
Storage Class Pricing Tiers (Illustrative – check AWS documentation for exact current prices):
Prices are often tiered, meaning the cost per GB decreases as you store more data. The rates below are illustrative and simplified for typical usage.
Illustrative Monthly Pricing per GB (USD) – These are examples and subject to change. Always refer to the official AWS S3 Pricing page for the most up-to-date information.
Note: Actual pricing can vary by AWS Region. This calculator uses simplified, representative rates.
Example Calculation Logic:
Total Monthly Cost = (Storage Cost) + (Request Cost) + (Data Transfer Out Cost) + (Data Transfer AWS Cost)
Storage Cost: (Amount Stored GB) * (Price per GB for Selected Storage Class)
Request Cost: (Number of PUT requests) * (Price per 1,000 PUT requests) + (Number of GET requests) * (Price per 1,000 GET requests)
Data Transfer Out Cost: (GB Transferred Out) * (Price per GB for Data Transfer Out)
Data Transfer AWS Cost: (GB Transferred AWS) * (Price per GB for Data Transfer to AWS Services)
S3 Intelligent-Tiering: Includes monitoring and automation fees per GB, plus the storage costs for each tier accessed. For simplicity, this calculator uses an aggregated rate representative of common access patterns.
Glacier Storage Classes: These have retrieval fees and potentially different request pricing. This calculator uses simplified estimates.
Disclaimer: This calculator provides an estimate only. Actual AWS bills may vary based on specific usage, region, discounts, and real-time pricing changes. Always consult the official AWS S3 pricing documentation for precise figures.
