AWS TCO Calculator vs Pricing Calculator: Which Tool for Migration Cost Comparison?
A company's IT director wants to present a business case for migrating from on-premises infrastructure to AWS. They need to compare the full cost of running on-premises (hardware, facilities, power, labour) against the cost of running equivalent workloads on AWS. Which AWS tool helps create this comparison?
Quick Answer
The answer is the AWS TCO Calculator. This tool is correct because it is specifically designed to compare the full cost of running on-premises infrastructure—including hardware, facilities, power, and labor—against the equivalent costs on AWS, generating a detailed side-by-side report that quantifies potential savings. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of cost comparison tools, often appearing as a scenario where a director needs to build a business case for migration; a common trap is confusing it with the AWS Pricing Calculator, which estimates future AWS costs alone but does not factor in on-premises expenses. To remember the difference, think of the TCO Calculator as the "before and after" tool—it compares your current on-premises total cost of ownership to the AWS alternative—while the Pricing Calculator only shows the "after" picture. A simple memory tip: TCO stands for Total Cost of Ownership, meaning it captures everything you own on-premises for a true comparison.
⚠ Common exam trap
Test-takers frequently confuse the AWS Pricing Calculator (which only estimates AWS service costs) with the TCO Calculator (which compares on-premises vs. AWS total costs), leading them to select Option A instead of C.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Pricing Calculator
Why it's wrong here
The Pricing Calculator estimates AWS cloud costs for a proposed architecture. It does not model on-premises costs or create a side-by-side TCO comparison between on-premises and cloud.
- ✗
AWS Cost Explorer
Why it's wrong here
Cost Explorer analyses historical AWS spending. It does not compare on-premises infrastructure costs to cloud costs.
- ✓
AWS TCO Calculator
Why this is correct
The AWS TCO Calculator is designed specifically for comparing on-premises infrastructure total cost of ownership with equivalent AWS costs. It accounts for hardware, software licenses, facilities, networking, and labour costs.
- ✗
AWS Budgets
Why it's wrong here
Budgets sets cost alerts for current AWS spending. It does not perform on-premises versus cloud cost comparison analyses.

Variation 1. A company is planning to migrate its on-premises data center to AWS. The Chief Financial Officer wants to compare the total cost of ownership (TCO) of the current on-premises infrastructure against running equivalent workloads on AWS. The company needs a tool that allows them to input details about their existing servers, storage, and network usage to generate a detailed cost comparison report. Which AWS tool should the company use to meet this requirement?
medium- A.AWS Pricing Calculator
- ✓ B.AWS Total Cost of Ownership (TCO) Calculator
- C.AWS Budgets
- D.AWS Cost Explorer
Why B: The AWS Total Cost of Ownership (TCO) Calculator is specifically designed to compare the costs of on-premises infrastructure with AWS by allowing users to input details about their existing servers, storage, and network usage. It generates a detailed report that highlights potential savings from migrating to AWS, directly addressing the CFO's requirement for a cost comparison.
Variation 2. A company currently runs its infrastructure in a colocation data center. The CIO wants to estimate the total cost of ownership (TCO) of migrating the existing workload to AWS, compared to continuing with the on-premises solution. The company has detailed data on current server specifications, power, cooling, and labor costs. Which AWS tool should the company use to perform this analysis?
easy- A.AWS Pricing Calculator
- ✓ B.AWS Total Cost of Ownership (TCO) Calculator
- C.AWS Cost Explorer
- D.AWS Budgets
Why B: The AWS Total Cost of Ownership (TCO) Calculator is specifically designed to compare the costs of running infrastructure on-premises versus on AWS. It allows you to input detailed data on server specifications, power, cooling, and labor costs to generate a side-by-side TCO comparison, which directly meets the CIO's requirement.
Variation 3. A company is evaluating a migration of its on-premises data center to AWS. The CIO wants a detailed report that compares the total cost of ownership (TCO) of the current on-premises infrastructure versus running the equivalent workloads on AWS. The report should include costs for hardware, software, labor, power, cooling, and facilities. Which AWS tool should the company use to generate this comparison?
medium- A.AWS Pricing Calculator
- ✓ B.AWS Total Cost of Ownership (TCO) Calculator
- C.AWS Cost Explorer
- D.AWS Trusted Advisor
Why B: The AWS Total Cost of Ownership (TCO) Calculator is specifically designed to compare the costs of on-premises infrastructure with AWS, including hardware, software, labor, power, cooling, and facilities. It generates a detailed report that breaks down these cost categories, making it the correct tool for the CIO's requirement.
Variation 4. A company is planning to migrate its on-premises data center to AWS. The finance team needs to compare the current on-premises infrastructure costs (including servers, storage, networking, and personnel) against the projected costs of running identical workloads on AWS over a three-year period. The team wants to input detailed specifications of their existing hardware and get a comprehensive report that highlights potential savings and provides a total cost of ownership (TCO) comparison. Which AWS tool should the finance team use?
medium- A.AWS Pricing Calculator
- B.AWS Cost Explorer
- ✓ C.AWS Total Cost of Ownership (TCO) Calculator
- D.AWS Simple Monthly Calculator
Why C: The AWS Total Cost of Ownership (TCO) Calculator is specifically designed to compare the costs of on-premises infrastructure with AWS, allowing users to input detailed hardware specifications (servers, storage, networking) and generate a comprehensive report that highlights potential savings over a chosen period (e.g., three years). This tool directly addresses the finance team's need for a TCO comparison, including personnel costs, which is not a feature of other AWS calculators.
