CLF-C02 Billing, Pricing, and Support Practice Question
A company wants to automatically receive an email alert whenever their monthly AWS spend is forecasted to exceed $10,000, or if it actually exceeds $10,000. Which AWS service provides this capability?
⚠ Common exam trap
Many candidates confuse AWS Cost Explorer's visualization capabilities with proactive alerting, or assume CloudWatch can handle cost-based alarms, but AWS Budgets is the only service that provides both forecasted and actual cost threshold alerts with email notifications.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Budgets
AWS Budgets allows you to set a custom budget (e.g., monthly cost budget of $10,000) and configure alert thresholds (actual or forecasted) that trigger an Amazon SNS notification, which can send an email alert. This directly meets the requirement to be notified when the forecasted or actual spend exceeds $10,000.
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
AWS Cost Explorer is an analytics tool that lets you visualize and break down actual historical costs by service, linked account, region, or tag and even produces a 12-month cost forecast. It does not, however, proactively send notifications when actual spending exceeds a threshold or when its forecast predicts overspend; you must actively open the console to view those charts. This makes it useful for understanding why a charge occurred, but not for automated monthly spend alerts, which is why the answer is AWS Budgets instead.
- ✗
AWS Pricing Calculator
Why it's wrong here
AWS Pricing Calculator is an estimation tool used during the planning phase to build a cost estimate for an architecture based on the instance types, storage, and data transfer you intend to use. It is a static calculator that carries out no monitoring of live AWS usage, has no linkage to real billing data, and therefore cannot trigger alerts or send notifications when a monthly budget is tested. Since the requirement is to monitor actual monthly spending and alert on exceedance, Pricing Calculator cannot perform that monitoring job.
- ✓
AWS Budgets
Why this is correct
AWS Budgets is the correct choice because it lets you define monthly cost, usage, reservation, and savings-plan budgets, then alert you by email or Amazon SNS when actual or forecasted spending crosses a configurable threshold. It can send separate alerts for percentage thresholds, forecasted exceedance, and actual exceedance, so you can act before a bill is delivered. Budgets also supports budget actions that can stop spend automatically, making it the comprehensive service for monitoring monthly spend.
- ✗
Amazon CloudWatch
Why it's wrong here
Amazon CloudWatch performs billing alarms by monitoring the EstimatedCharges metric and publishing an alarm to an SNS topic when a fixed dollar threshold is crossed, but it can only monitor the account's total estimated charge. It cannot alert you when a forecast will exceed a budget, cannot track usage or reservation coverage, and requires customers to create the alarm manually. AWS Budgets is the modern, more feature-rich replacement, so CloudWatch is not the correct answer.
