S3 Calculator – Loan calculator

Amazon S3 Monthly Cost Estimator

Use this calculator to estimate your potential monthly costs for Amazon S3 (Simple Storage Service). S3 pricing is primarily based on storage used, data transfer out, and the number of requests made. This calculator uses simplified pricing tiers for the US East (N. Virginia) region as of early 2023. Actual costs may vary based on specific usage patterns, region, and AWS pricing updates.

Standard Storage (GB/month): Average monthly data stored in S3 Standard.

Standard-IA Storage (GB/month): Average monthly data stored in S3 Standard-Infrequent Access.

Glacier Storage (GB/month): Average monthly data stored in S3 Glacier.

Data Transfer Out to Internet (GB/month): Total data transferred out from S3 to the internet.

PUT/COPY/POST/LIST Requests (per 1,000/month): Number of write/list requests (in thousands).

GET/SELECT Requests (per 1,000/month): Number of read requests (in thousands).

Understanding Amazon S3 Costs

Amazon S3 (Simple Storage Service) is a highly scalable, durable, and secure object storage service offered by AWS. Its pricing model is designed to be flexible, allowing users to pay only for what they use. Understanding the key cost components is crucial for effective budget management.

1. Storage

This is the most straightforward cost. You pay for the amount of data you store in S3 per month, measured in Gigabytes (GB). S3 offers various storage classes, each optimized for different access patterns and cost points:

S3 Standard: For frequently accessed data. Highest cost per GB, but lowest access costs.
S3 Standard-Infrequent Access (S3 Standard-IA): For data accessed less frequently but requiring rapid access when needed. Lower storage cost than Standard, but higher retrieval costs.
S3 Glacier: For archival data that is rarely accessed. Lowest storage cost, but retrieval can take minutes to hours and incurs retrieval fees.
(Other classes like S3 One Zone-IA, S3 Intelligent-Tiering, S3 Glacier Deep Archive also exist but are not included in this simplified calculator.)

Calculator Rates (US East – N. Virginia, simplified):

S3 Standard: $0.023 per GB/month
S3 Standard-IA: $0.0125 per GB/month
S3 Glacier: $0.004 per GB/month

2. Data Transfer Out

You are charged for data transferred out of S3 to the internet. Data transferred into S3 is generally free. AWS provides a free tier for data transfer out (typically the first 1 GB per month). Costs increase as the volume of data transferred out grows.

Calculator Rate (US East – N. Virginia, simplified):

First 1 GB/month: Free
Subsequent GBs: $0.09 per GB

3. Requests

S3 charges for the number of requests made to your data. These include PUT (upload), COPY, POST, LIST, and GET (download) requests. The cost per request varies by request type and storage class. For example, PUT requests are typically more expensive than GET requests.

Calculator Rates (US East – N. Virginia, simplified for S3 Standard):

PUT/COPY/POST/LIST Requests: $0.005 per 1,000 requests
GET/SELECT Requests: $0.0004 per 1,000 requests

Important Considerations:

Region: S3 pricing varies by AWS region. This calculator uses US East (N. Virginia) rates.
Minimum Storage Duration: S3 Standard-IA and Glacier have minimum storage durations (e.g., 30 days for IA, 90 days for Glacier). If you delete objects before this period, you're still charged for the minimum duration.
Minimum Billable Object Size: For IA and Glacier, small objects might be billed as if they were larger (e.g., 128 KB for IA, 40 KB for Glacier).
Data Retrieval: Glacier and Standard-IA incur data retrieval costs in addition to storage costs. This calculator simplifies by only considering storage and general requests.
Free Tier: AWS offers a free tier for new accounts, which includes 5 GB of S3 Standard storage, 20,000 GET requests, 2,000 PUT requests, and 100 GB of data transfer out per month for 12 months. This calculator does not automatically apply the free tier beyond the 1GB data transfer out.

This calculator provides an estimate and should not be considered a final bill. Always refer to the official AWS S3 pricing page for the most accurate and up-to-date information.
