AWS Pricing Calculator: Estimate Monthly Costs Before Deployment
A company is considering AWS for their new application. Which tool allows them to compare the cost of running their workloads on AWS versus on-premises, and estimate the potential savings?
Quick Answer
The answer is the AWS Pricing Calculator. This tool is correct because it is specifically designed to compare the cost of running workloads on AWS versus on-premises environments, allowing you to input your current infrastructure details—such as server specifications, storage, and network usage—to generate a detailed cost comparison and estimate potential savings. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of cost management tools, and a common trap is confusing the AWS Pricing Calculator with the AWS Simple Monthly Calculator or AWS Cost Explorer; remember that only the Pricing Calculator (formerly the TCO Calculator) handles the direct on-premises versus AWS comparison. For a memory tip, think of “Pricing” as “Price vs. Premises”—if the question asks about comparing to on-premises, the answer is always the AWS Pricing Calculator.
⚠ Common exam trap
Many exam-takers confuse AWS Cost Explorer (which shows historical AWS spending) with the AWS Pricing Calculator (which is used for upfront cost comparison and estimation before migration), leading them to select Cost Explorer incorrectly.

Correct answer & explanation
✓
AWS Pricing Calculator
AWS Pricing Calculator (formerly TCO Calculator) is specifically designed to compare the cost of running workloads on AWS versus on-premises environments. It allows users to input their current on-premises infrastructure details (such as server specifications, storage, and network usage) and generates a detailed cost comparison, including estimated savings from migrating to AWS. This directly matches the question's requirement for comparing costs and estimating potential savings.
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 Cost Explorer
Why it's wrong here
Cost Explorer analyzes actual historical AWS spending — it requires existing AWS usage and can't compare hypothetical on-premises vs. cloud costs.
- ✓
AWS Pricing Calculator
Why this is correct
AWS Pricing Calculator estimates costs for AWS architectures and supports TCO analysis comparing on-premises infrastructure costs versus AWS cloud costs for migration business cases.
- ✗
AWS Budgets
Why it's wrong here
Budgets monitor actual spending against thresholds — they don't estimate or compare hypothetical costs between on-premises and cloud.
- ✗
AWS Trusted Advisor
Why it's wrong here
Trusted Advisor analyzes existing AWS resources for optimization — it doesn't compare AWS vs. on-premises costs.

Same concept, more angles
2 more ways this is tested on CLF-C02
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which tool allows a company to estimate the monthly cost of running a new AWS architecture before deploying any resources?
medium- A.AWS Cost Explorer
- ✓ B.AWS Pricing Calculator
- C.AWS Budgets
- D.AWS Trusted Advisor
Why B: The AWS Pricing Calculator (formerly Simple Monthly Calculator) allows users to estimate the monthly cost of AWS services by configuring resources like EC2 instances, storage, and data transfer before deployment. It provides a detailed cost breakdown based on selected regions, instance types, and usage patterns, enabling informed budgeting without incurring actual charges.
Variation 2. A startup is planning a new web application on AWS. The architecture will use Amazon EC2 for compute, Amazon RDS for the database, and Amazon S3 for static assets. The team needs to estimate the monthly cost of running this application before building it. They want to compare costs across different instance types, regions, and pricing models (On-Demand vs. Reserved Instances), and they also need to account for data transfer costs. Which AWS tool should the team use to create this estimate?
medium- A.AWS Cost Explorer
- B.AWS Total Cost of Ownership (TCO) Calculator
- C.AWS Budgets
- ✓ D.AWS Pricing Calculator
Why D: AWS Pricing Calculator (formerly AWS Simple Monthly Calculator) is the correct tool because it allows users to estimate monthly costs by selecting specific EC2 instance types, RDS configurations, S3 storage classes, and data transfer volumes. It supports comparing On-Demand vs. Reserved Instance pricing across different regions, making it ideal for pre-build cost estimation.
