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)

TIP

Some rows include a View button that opens the respective metrics graphs for deeper analysis.

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.

Total Cost

Component	Description
Total Cost	Aggregated total S3 bucket cost across all categories

Storage Costs

Subcategory	Description
Standard	Standard storage class
Standard-IA	Infrequent Access
One Zone-IA	One zone infrequent access
Glacier	Long-term archive storage
Glacier Deep Archive	Cheapest, long-term archive
Glacier Flexible Retrieval	Archive with flexible access
Glacier Instant Retrieval	Instant retrieval archive
Express One Zone	Single-zone, low-latency storage
Reduced Redundancy	Legacy option for lower durability
Intelligent Tiering	Auto-tiering based on access

Storage Metrics View

Storage Metrics show how your bucket’s storage size and object count change over time. These insights help track growth and cost trends.

Graph Name	Metrics Displayed	Description
Total Storage	Cost, Storage Size (GB), Time	Displays how much storage (in GB) is used over time and its associated cost. Helps identify growth trends and cost drivers.
Object Count	Object Count, Time	Shows the total number of stored objects over time. Useful for understanding object-level data sprawl and management implications.

Requests & API Calls

Subcategory	Description
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	Query objects with S3 Select
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.

Data Transfer Costs

Subcategory	Description
Intra-Region Data Transfer Out	Transfers within the same region
Inter-Region Data Transfer Out	Transfers across AWS regions
Data Transfer Out via Internet	Public internet transfers
Data Transfer Out to CloudFront	Edge-optimized transfers

Data Transfer Metrics View

This view provides visibility into data movement trends, helping you assess cost implications and optimize your data transfer strategies.

Graph Name	Displays	Description
Bucket to Internet Transfer	Transfer Cost, Transfer Size (GB), Time	Tracks the volume of data transferred from your S3 bucket to the internet, alongside its associated cost over time. Useful for identifying spikes in public access or data sharing.
Cross-Region Outbound Transfer	Transfer Size (GB), Time	Visualizes the amount of data moved from your bucket to other AWS regions over time. Helps monitor inter-region sync activity.

Lifecycle Costs

Subcategory	Description
Transitions	Automatic storage class changes
Early Deletion Fees	Charges for premature deletions
Restore Requests	Costs to restore from archive tiers

Replication Costs

Subcategory	Description
Replication Request Costs	Charges for cross-region replication

Intelligent Tiering Costs

Subcategory	Description
Frequent Access Tier	Regularly accessed objects
Infrequent Access Tier	Objects accessed less often
Archive Access Tier	Long-term archival tier
Deep Archive Access Tier	Coldest storage tier
Archive Instant Access Tier	Fast access to archive data
Monitoring & Automation	Cost of tiering decisions

Data Retrieval & Restore Costs

Subcategory	Description
Data Retrieval	Retrieval from archive tiers
Data Restore	Restore request charges
Bulk Retrieval Requests	High-volume archive retrieval
Expedited Retrieval Requests	Faster access at higher cost

Other Costs

Component	Description
Other Costs	Any cost not categorized above
