S3 Storage Cost Calculator



Calculating storage costs for S3 (Simple Storage Service) can be essential for businesses and individuals managing large amounts of data in the cloud. This S3 Storage Cost Calculator helps you estimate your expenses based on your file size and the number of days you plan to store your data.


To calculate the storage cost, we use a simple formula:

Total Cost = File Size (GB) × Storage Days × Cost per GB per Day

How to Use:

  1. Enter the file size in gigabytes (GB) that you want to store in your S3 bucket.
  2. Input the number of days you plan to keep the file in storage.
  3. Click the “Calculate” button to determine the estimated cost.


Let’s say you have a 10 GB file that you want to store in your S3 bucket for 30 days. Using the calculator:

  • File Size: 10 GB
  • Storage Days: 30 days
  • Total Cost = 10 GB × 30 days × $0.023/GB/day = $6.90

So, it would cost you $6.90 to store a 10 GB file for 30 days in your S3 bucket.
