Cost Explorer provides an intuitive interface with pre-built reports and customizable views that allow you to analyze your AWS costs and usage patterns. You can examine data for up to the last 12 months and forecast spending for the next 12 months based on historical trends.
Key features include:
**Filtering and Grouping**: You can filter costs by various dimensions such as service, linked account, region, instance type, tag, and more. This granular approach helps identify which resources are driving costs.
**Reserved Instance Analysis**: Cost Explorer helps you understand RI utilization and coverage, enabling better purchasing decisions for long-term savings.
**Savings Plans Recommendations**: The tool provides recommendations for Savings Plans based on your historical usage patterns, potentially reducing compute costs significantly.
**Cost Allocation Tags**: By using tags, you can categorize and track costs by project, department, or environment, making chargeback and showback processes more efficient.
**API Access**: Cost Explorer offers API access for programmatic retrieval of cost data, enabling integration with custom dashboards and automation workflows.
**Forecasting**: Built-in forecasting capabilities help predict future spending based on historical patterns, assisting with budget planning.
Best practices for SysOps Administrators include setting up regular cost reviews, creating custom reports for stakeholders, implementing cost allocation tags across resources, and using the recommendations engine to identify optimization opportunities.
Cost Explorer is free to use, though API requests incur a small charge. Combined with AWS Budgets for alerting, it forms a comprehensive cost management solution that helps organizations maintain financial governance over their cloud infrastructure.

Why AWS Cost Explorer is Important
AWS Cost Explorer is a critical tool for any organization using AWS services. Understanding your cloud spending is essential for budget management, identifying cost optimization opportunities, and ensuring financial accountability. For SysOps Administrators, mastering Cost Explorer demonstrates the ability to manage operational costs effectively, which is a core responsibility in maintaining AWS infrastructure.
What is AWS Cost Explorer?
AWS Cost Explorer is a free tool that provides a visual interface to view, analyze, and manage your AWS costs and usage over time. It allows you to:
• View cost and usage data for the past 13 months • Forecast costs for the next 12 months • Create custom reports and visualizations • Identify spending trends and anomalies • Analyze costs by service, linked account, tag, or other dimensions • Access granular data at daily or monthly levels • Use the Cost Explorer API for programmatic access
How AWS Cost Explorer Works
Data Collection: AWS automatically collects billing and usage data from all your AWS services. This data becomes available in Cost Explorer approximately 24 hours after you incur charges.
Filtering and Grouping: You can filter data by various dimensions including: • Service (EC2, S3, RDS, etc.) • Linked Account • Region • Availability Zone • Instance Type • Usage Type • Tags (cost allocation tags) • Purchase Option (On-Demand, Reserved, Spot)
Reports and Visualizations: Cost Explorer provides pre-built reports such as: • Monthly costs by service • Daily costs • Reserved Instance utilization • Reserved Instance coverage • Savings Plans utilization and coverage
Forecasting: Using machine learning algorithms, Cost Explorer can predict your future spending based on historical usage patterns. Forecasts are available for up to 12 months.
Rightsizing Recommendations: Cost Explorer provides EC2 rightsizing recommendations to help identify underutilized instances that could be downsized to save money.
Key Features to Remember
• Cost Allocation Tags: Enable cost allocation tags to track spending by project, department, or environment • Hourly Granularity: Available with hourly granularity for the last 14 days • Daily Granularity: Available for the last 13 months • API Access: Cost Explorer API allows programmatic access to cost data • Saved Reports: Create and save custom reports for repeated analysis • Resource-Level Data: Enable to see costs at the individual resource level
Exam Tips: Answering Questions on AWS Cost Explorer
Tip 1: When a question asks about visualizing or analyzing AWS costs over time, Cost Explorer is typically the correct answer. It is the primary tool for cost analysis and visualization.
Tip 2: Remember the distinction between Cost Explorer and AWS Budgets. Cost Explorer is for analyzing past and current spending, while AWS Budgets is for setting alerts and thresholds for future spending.
Tip 3: If a question mentions forecasting future AWS costs, Cost Explorer is the answer. It can forecast up to 12 months ahead.
Tip 4: For questions about identifying underutilized EC2 instances, remember that Cost Explorer provides rightsizing recommendations.
Tip 5: Questions about tracking costs by department, project, or team typically involve cost allocation tags combined with Cost Explorer filtering.
Tip 6: Know that Cost Explorer data is available after approximately 24 hours - it is not real-time.
Tip 7: If a question asks about Reserved Instance utilization or coverage reports, Cost Explorer is the tool that provides these specific reports.
Tip 8: Remember that Cost Explorer is free to use for basic functionality, but the Cost Explorer API incurs charges per request.
Tip 9: For questions requiring programmatic access to cost data or integration with other systems, the Cost Explorer API is the solution.
Tip 10: Distinguish Cost Explorer from AWS Cost and Usage Reports (CUR). CUR provides the most detailed cost data in CSV format for deep analysis, while Cost Explorer provides visual analysis and is more user-friendly.
