You will learn: how to set a budget alarm that emails you before the bill grows.

Checked with AWS 2026-11 on 1 Nov 2026

The problem

Tap each point on the timeline.

Tap the story. One email on Saturday would have saved it. That email is a budget alarm.

Watch

A is a line on the bill. When spending passes it, AWS emails you. AWS Budgets has ready-made templates. Sort what each one does.

Drag a card into a box. Or tap the card, then tap the box.

Try it

Set it up in the console. Put the steps in order.

First step at the top. Put these in order. Use the arrows, or drag.

Choose Budgets, then Create budget
Choose Use a template
Type the email you read every day
Pick Zero spend budget
Create the budget
Open Billing and Cost Management

Watch

The same budget can live in a file. Tap the line that says when AWS emails you.

Tap the line with the trigger point.

Try it

Now build the command that sends both files to AWS.

Tap the pieces in the right order.

Predict

Kancil’s alarm email arrives. Does AWS stop the forgotten server?

Check

Budget data updates up to three times a day, so emails can come hours late. Good habit, or needs work?

Swipe right for good, left for needs work. Or use the buttons.

Set the alarm before you build anything.

You did it!

You can now set a budget alarm before you build anything.

Go deeper (optional)

A second option is a CloudWatch . First switch on billing alerts. The billing data lives in US East (N. Virginia), us-east-1, so make the alarm there.
