CLF-C02 Billing, Pricing, and Support Practice Question
A company is planning to migrate its on-premises infrastructure to AWS. The operations team wants to compare the total cost of ownership (TCO) between running workloads on-premises and running them on AWS. They need a tool that can accept details about their current on-premises servers (number of servers, CPU, memory, storage) and produce a detailed report comparing costs over a specified period, including savings from avoided hardware purchases, IT labor, and data center costs. Which AWS tool should the operations team use?
⚠ Common exam trap
Candidates often confuse the AWS Pricing Calculator (which estimates AWS service costs) with the TCO Calculator (which compares on-premises vs. AWS costs), leading them to select the Pricing Calculator even though it lacks the on-premises input and comparative savings features.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Total Cost of Ownership (TCO) Calculator
The AWS Total Cost of Ownership (TCO) Calculator is specifically designed to compare the costs of running on-premises infrastructure versus AWS. It accepts detailed inputs about existing on-premises servers (such as CPU, memory, and storage) and generates a comprehensive report that includes savings from avoided hardware purchases, IT labor, and data center costs over a user-specified period. This directly matches the operations team's requirement for a detailed TCO comparison.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Cost Explorer
Why it's wrong here
AWS Cost Explorer is used to visualize, understand, and manage AWS costs and usage over time for existing AWS resources. It does not accept on-premises infrastructure details or provide a comparison with on-premises costs; it only analyzes historical AWS usage.
When this WOULD be correct
A company wants to visualize and analyze its existing AWS spending patterns, identify cost trends, and forecast future AWS costs based on historical usage. The question would ask for a tool to monitor and explore current AWS costs.
- ✓
AWS Total Cost of Ownership (TCO) Calculator
Why this is correct
The AWS TCO Calculator is the correct tool for this scenario. It accepts input about existing on-premises infrastructure and provides a detailed comparison of costs between running on-premises and on AWS, including savings from hardware, labor, and data center expenses. It helps organizations estimate the financial benefits of migration.
- ✗
AWS Pricing Calculator
Why it's wrong here
The AWS Pricing Calculator is used to estimate the cost of running specific AWS services (e.g., EC2, S3) based on your expected usage. It does not accept on-premises infrastructure details and cannot perform a TCO comparison between on-premises and cloud.
When this WOULD be correct
When a company wants to estimate the monthly cost of running specific AWS services (e.g., EC2, S3) before deployment, without comparing to on-premises infrastructure.
- ✗
AWS Cost and Usage Report
Why it's wrong here
The AWS Cost and Usage Report (CUR) provides detailed billing data about your AWS usage, but it does not accept on-premises infrastructure input or generate a TCO comparison. It is used for in-depth analysis of existing AWS costs, not for pre-migration planning.
When this WOULD be correct
A company needs a detailed CSV report of its AWS usage and costs for custom analysis or to integrate with third-party tools for cost allocation and budgeting.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CLF-C02 exam frequently reuses these exact scenarios with slightly different constraints.
✓AWS Total Cost of Ownership (TCO) CalculatorCorrect answer▾
Why this is correct
The AWS TCO Calculator is the correct tool for this scenario. It accepts input about existing on-premises infrastructure and provides a detailed comparison of costs between running on-premises and on AWS, including savings from hardware, labor, and data center expenses. It helps organizations estimate the financial benefits of migration.
✗AWS Cost ExplorerWrong answer — click to see why▾
Why this is wrong here
AWS Cost Explorer analyzes historical cost and usage data, but does not accept on-premises server details to compare TCO with AWS. It cannot model future costs or savings from avoided hardware purchases and data center costs.
★ When this WOULD be the correct answer
A company wants to visualize and analyze its existing AWS spending patterns, identify cost trends, and forecast future AWS costs based on historical usage. The question would ask for a tool to monitor and explore current AWS costs.
Why candidates choose this
Candidates may confuse 'cost analysis' with 'TCO comparison,' assuming Cost Explorer can compare on-premises vs. AWS costs, but it only works with AWS data.
✗AWS Pricing CalculatorWrong answer — click to see why▾
Why this is wrong here
AWS Pricing Calculator estimates costs for AWS services but does not compare on-premises TCO or include savings from avoided hardware purchases, IT labor, and data center costs.
★ When this WOULD be the correct answer
When a company wants to estimate the monthly cost of running specific AWS services (e.g., EC2, S3) before deployment, without comparing to on-premises infrastructure.
Why candidates choose this
Candidates confuse 'Pricing Calculator' with 'TCO Calculator' because both involve cost estimation, but the Pricing Calculator lacks the on-premises comparison and TCO analysis features.
✗AWS Cost and Usage ReportWrong answer — click to see why▾
Why this is wrong here
AWS Cost and Usage Report provides detailed billing and usage data but does not compare on-premises costs to AWS costs or generate TCO reports.
★ When this WOULD be the correct answer
A company needs a detailed CSV report of its AWS usage and costs for custom analysis or to integrate with third-party tools for cost allocation and budgeting.
Why candidates choose this
Candidates may confuse cost reporting tools with TCO analysis tools, assuming that any cost-related tool can compare on-premises and cloud costs.
