Cost & Usage Breakdown
Overview
The Cost & Usage Breakdown tab gives you full visibility into how your S3 bucket is incurring costs.
Date Range
Use the date range selector at the top of the page to adjust the analysis period. All values update to reflect the selected time window.
Breakdown by Cost Categories
The Cost & Usage Breakdown presents a unified table containing multiple cost components, each displaying:
Metric / Cost Component – The category of the charge
Cost – Total cost incurred during the selected date range
Value – Corresponding usage metric (e.g., GB stored, number of requests, GB transferred)
NOTE
Only categories with actual cost or usage data for the selected time range will appear in the table. Empty or non-applicable categories are automatically excluded to keep the view relevant and focused.

Requests & API Calls
PUT Requests
Upload object operations
POST Requests
Form-based uploads
LIST Requests
List bucket contents
COPY Requests
Copy objects within buckets
GET Requests
Read/download object
SELECT Requests

Multipart Upload Operations
Upload large objects in parts
HEAD Requests
Fetch object metadata
Messaging Delete Operations
Delete object notification ops
Request & API Calls Metrics View
This view helps you analyze the operational load on your bucket and the associated costs of API requests, segmented by request type.
Write & List Operations
Graph Name
Metrics Displayed
Description
List Bucket
Request Count, Time
Shows the number and cost of ListBucket operations. Useful for identifying listing-heavy usage.
Put Object
Request Count, Cost, Time
Tracks PutObject requests, reflecting how often new data is uploaded and its cost implications.
Copy Object
Request Count, Cost, Time
Monitors CopyObject actions, used when duplicating objects. Helps track internal data movement costs.
Upload Part
Request Count, Cost, Time
Captures multipart upload activity. Indicates frequency and cost of large object uploads.
Initiate Multipart Upload
Request Count, Cost, Time
Shows how often multipart uploads are started. Helps detect incomplete uploads or cost spikes.
Complete Multipart Upload
Request Count, Cost, Time
Tracks completions of multipart uploads. Used to assess efficiency and completion rate.
Read Operations
Graph Name
Metrics Displayed
Description
Head Object
Request Count, Time
Displays metadata fetches (HeadObject). Indicates automated or monitoring access to stored objects.
Get Object
Request Count, Cost, Time
Tracks object retrievals, critical for understanding download behavior and its financial impact.
Read Object Tagging
Request Count, Time
Shows tagging data fetches. Highlights costs tied to metadata access and governance practices.
