Billing alarms notify you when your AWS costs exceed predefined thresholds. This early warning system allows you to take actions to adjust usage, optimize resources, or investigate any unexpected spikes in spending.
Budget Management
Setting AWS billing alarms can align your AWS usage with budgetary limits. This helps in preventing budget overruns and ensures financial discipline within your business.
Operational Efficiency
Monitoring real-time AWS costs helps identify inefficient resource usage or unnecessary expenditures. This data-driven approach enables you to make informed decisions to optimize costs.
Compliance & Governance
For businesses with strict compliance requirements, enabling AWS billing alarms ensures adherence to budgetary guidelines. It helps in maintaining transparency & accountability in AWS spending.
What are the Requirements for Enabling the AWS Billing Alarm?
To enable AWS billing alarms, you need the following:
AWS Account
You must have an active AWS account with sufficient permissions to access and configure CloudWatch alarms.
Access to CloudWatch
Ensure access to AWS CloudWatch, as billing alarms are configured & managed through this service.
Define Thresholds
Determine the thresholds at which you want to receive notifications. This involves setting the amount of spending or usage that triggers the alarm.
Action Configuration
Decide on the actions to be taken when the alarm state changes (e.g., sending notifications via email or triggering automated responses).
Monitoring
Regularly monitor your AWS usage and adjust alarm thresholds according to your requirements to stay aligned with your business needs.
How to Create an AWS Billing Alarm?
Here is the step-by-step guide to setting up an AWS billing alarm:
Step 1: Accessing the AWS Management Console
Log in to the AWS Console
Open the AWS Management Console and log in with your credentials.
Step 2: Navigating to the CloudWatch Dashboard
Open CloudWatch
In the AWS Management Console, navigate & select “CloudWatch” under the “Management & Governance” section.

Step 3: Creating a Billing Alarm
Access Alarms
In the CloudWatch dashboard, locate and click “Alarms” in the left-hand navigation pane.

Create Alarm
Click the “Create Alarm” button to set up an AWS billing alarm.
Step 4: Choosing Metric and Threshold
Select Metric
Under the “Create Alarm” wizard, choose “Billing” from the list of metrics.
Choose Metric
Select the “Total Estimated Charge” metric – which represents your current AWS charges.

Set Conditions
Define the conditions for the alarm. For example, set the threshold to trigger the alarm when the estimated charges exceed a specific amount over a certain period (e.g., $100 over a day).

Step 5: Configuring Alarm Threshold
Specify Threshold
Enter the threshold value and specify the period to which AWS should evaluate your charges (e.g., $100 over 24 hours).

Step 6: Defining Actions
Set Actions
Decide what action AWS should take when the alarm state changes. Options include sending an email notification or triggering an AWS Lambda function for automated responses.
Step 7: Naming & Description
Provide Details
Give your alarm a name and description that indicates its purpose and the threshold it monitors. This helps in identifying and managing multiple alarms effectively.

Review Settings
Double-check all the configurations you have made for accuracy. Ensure the threshold and actions are set according to your cost management strategy.

Create Alarm
Click “Create Alarm” to finalize and activate the billing alarm.
Step 9: Testing the Alarm (Optional but Recommended)
Verify Setup
To ensure the alarm functions correctly, consider intentionally triggering it by performing activities that exceed the defined threshold.
Step 10: Monitoring & Managing Alarms
Monitor Alarms
Once created, you can monitor your billing alarm from the CloudWatch dashboard. The alarm will display its current state (OK, ALARM, INSUFFICIENT_DATA) based on your AWS spending against the defined threshold.
Managing Alarms
You can manage alarms by adjusting thresholds, modifying actions, or deleting alarms that are no longer relevant.
