Cost Management Tools: Billing Dashboard, CUR, Tags, and Support Resources
Learn about the AWS Billing Dashboard, Cost & Usage Reports, cost allocation tags, and how AWS Professional Services and the Partner Network can help.
What this lesson covers
The previous lessons introduced Cost Explorer and AWS Budgets. This lesson adds three more pieces of the cost-management picture:
- AWS Billing Dashboard, your top-level spending summary
- Cost & Usage Reports (CUR), the most detailed billing dataset AWS provides
- Cost allocation tags, how you label resources so costs can be tracked by team, project, or environment
We will also briefly cover AWS Professional Services and the AWS Partner Network (APN) as resources that can help with migration and cost optimization.
AWS Billing Dashboard
The Billing Dashboard is the first page you see in the AWS Billing and Cost Management console. It provides a high-level, month-to-date summary of your account charges.
What you see:
- Total estimated charges for the current month
- Breakdown by service (top spending services)
- Free Tier usage tracking (if applicable)
- Links to more detailed tools like Cost Explorer and Budgets
When to use it: Quick daily or weekly check on overall spending. If something looks off, drill into Cost Explorer for details.
Cost & Usage Reports (CUR)
Cost & Usage Reports are the most granular billing dataset AWS offers. CUR delivers line-item records for every resource, every hour (or day), with every charge broken out.
Key characteristics:
- Delivered to an S3 bucket you configure
- Can be queried with Amazon Athena, loaded into Redshift, or processed with any data tool
- Includes resource IDs, usage types, pricing details, and tag values
- Updated multiple times per day
When to use it: Deep cost analysis, custom reporting, chargeback systems, or any scenario where Cost Explorer's built-in charts are not detailed enough.
How these tools compare
| Tool | Detail Level | Best For |
|---|---|---|
| Billing Dashboard | High-level summary | Quick glance at month-to-date spend |
| Cost Explorer | Interactive charts, filtering by service/tag/region, 13-month history | Trend analysis, identifying cost drivers |
| AWS Budgets | Threshold-based alerts | Getting warned before overspending |
| Cost & Usage Reports (CUR) | Line-item records for every charge | Deep analysis, custom reports, data warehouse queries |
Tip
Think of these tools as a zoom lens: Billing Dashboard is the wide shot, Cost Explorer lets you zoom in interactively, and CUR gives you the raw pixels for maximum detail.
Cost allocation tags
Tags are key-value pairs you attach to AWS resources. When you activate them as cost allocation tags in the Billing console, they appear as columns in Cost Explorer and CUR, letting you slice costs by any dimension you define.
Two types of cost allocation tags:
- User-defined tags: you create them (e.g.,
Team=Platform,Environment=Production,Project=MobileApp) - AWS-generated tags: AWS creates them automatically (e.g.,
aws:createdBywhich records who launched the resource)
How to use cost allocation tags
- Define a tagging strategy, decide which tags every resource must have (team, environment, project, cost center)
- Apply tags when creating resources, or retroactively tag existing ones
- Activate tags in the Billing console, only activated tags appear in cost reports
- Filter and group in Cost Explorer or CUR, see exactly where money is going
Note
Tags only affect cost reporting after they are activated. They do not apply retroactively to past billing data. Start tagging early.
Example: tracking costs by team
A company with three teams sharing one AWS account applies a Team tag to every resource:
| Resource | Team Tag | Monthly Cost |
|---|---|---|
| EC2 web servers | Team=Frontend | $420 |
| RDS database | Team=Backend | $310 |
| S3 data lake | Team=Analytics | $85 |
| Lambda functions | Team=Backend | $12 |
After activating the Team tag, Cost Explorer can show: Backend = $322, Frontend = $420, Analytics = $85.
Consolidated billing and Organizations
If your company uses AWS Organizations to manage multiple AWS accounts, consolidated billing combines the charges from all member accounts into a single bill on the management account.
Benefits:
- Single bill, one invoice for all accounts
- Volume discounts, aggregated usage across accounts can qualify for tiered pricing discounts (e.g., S3 storage tiers)
- Easier tracking; Cost Explorer and CUR show all accounts together
Note
For a deeper look at AWS Organizations, consolidated billing, and Service Control Policies, see Module 5.2, Lesson 6 in this course.
Reserved Instance and Savings Plans Sharing in Organizations
With AWS Organizations consolidated billing, Reserved Instance and Savings Plans discounts are shared across all member accounts automatically.
How RI sharing works:
- RIs purchased by any account apply to matching usage in any other account within the organization
- Accounts with matching usage receive the hourly discount first (no explicit configuration needed)
- The management account can disable sharing for specific accounts if needed for accounting purposes
- RIs and Savings Plans cannot be shared across multiple Organizations - they apply only within the Organization where purchased
Best practice: Centralize RI purchasing in the management account for easier tracking, maximum utilization, and cleaner cost allocation.
AWS Professional Services and Partner Network
Two resources that can help organizations plan migrations, optimize costs, or implement AWS solutions:
AWS Professional Services:
- A global team of AWS experts who work directly with customers
- Help with cloud migration, architecture design, and operational optimization
- Typically engaged for large-scale or complex projects
AWS Partner Network (APN):
- A global community of AWS-certified technology and consulting partners
- Technology Partners provide software solutions that run on or integrate with AWS
- Consulting Partners help customers design, build, migrate, and manage workloads on AWS
- Useful when you need specialized expertise your team does not have in-house
