How to Get Started with AWS Cost Explore?

1 Activate Cost Explorer

AWS Cost Explorer is not activated by default. Log in to the AWS Management Console and navigate to the Billing and Cost Management Dashboard. There, you can enable Cost Explorer with just one click.

Tip: It may take up to 24 hours for your first data load to appear.

2 Explore Pre-Built Reports

AWS provides several pre-built reports, including:

Monthly spend by service
Reserved Instance (RI) utilization
Savings Plans coverage
Cost by linked account

These reports are excellent starting points for gaining a quick overview of your spending patterns without building custom views.

3 Use Filters and Grouping

Cost Explorer offers robust filtering to break down your expenses. You can filter by:

• Region
  
  

• AWS Service
  
  

• Linked account
  
  

• Tag
  
  

• Usage type
  
  

Grouping data helps you answer questions like:
Which team spends the most?
Which service is growing fastest?

This functionality helps you drill down to the most relevant cost drivers.

4 Set Up Cost Allocation Tags

Tagging resources is a crucial best practice in AWS. Cost allocation tags allow you to categorize expenses based on team, project, or environment.

For example:

• Department:Marketing
  
  

• Project:AppRedesign
  
  

Once you enable these tags in the Billing Console, you can track costs more precisely in Cost Explorer.

5 Analyze Trends Over Time

One of the biggest benefits of Cost Explorer is its trend visualization. You can:

View costs daily, monthly, or quarterly
Identify sudden spending spikes
Correlate changes with business events (like a product launch)

This makes it much easier to connect financial data with operational events.

6 Forecast Future Costs

AWS Cost Explorer offers a forecasting feature that uses machine learning to predict future spending based on historical trends.

Benefits include:
More accurate budget planning
Early warnings of budget overruns
Ability to align budgets with growth

For example, if your app usage grows seasonally, forecasting can help you plan for traffic surges.

7 Build Custom Reports

While pre-built reports are helpful, custom reports give you maximum control. You can build reports to match your teams goals, such as:

• Costs per team
  
  

• Reserved Instance utilization
  
  

• Savings Plan adoption rates
  
  

Save these reports to revisit them monthly or weekly, creating a habit of expense awareness.

8 Share Reports with Stakeholders

Cost Explorer makes collaboration easy by allowing you to download and share reports. You can export data in CSV format or share screenshots in team meetings.

This promotes transparency and accountability across finance, DevOps, and executive leadership.

Best Practices to Master AWS Cost Explorer

Automate budgets Combine Cost Explorer with AWS Budgets for alerts
Train your team Educate developers and managers on how to read cost reports
Monitor Reserved Instances Watch utilization rates to maximize savings
Align reports with business goals Ensure what you track supports what you want to achieve

Common Mistakes to Avoid

Ignoring untagged resources: They can quickly become a black hole in your budget
Setting and forgetting budgets: Regular adjustments are key
Not involving the right people: Cross-functional collaboration is vital
Overcomplicating reports: Keep dashboards simple for clarity

Mastering Cost Explorer means making it part of a culture of financial transparency, rather than a once-in-a-while activity.
