Introducing auto-adjusting budgets

Starting today, you can use AWS Budgets to create auto-adjusting budgets. An auto-adjusting budget dynamically sets your budget amount based on historical cost or usage over a time range that you specify. This reduces the guesswork in setting a budget limit and keeps you updated as your spend patterns change. Auto-adjusting budgets are generally available in all public AWS Regions.

With this launch, you can set a budget method based on fixed, planned or auto-adjusting limits. If you’re looking to catch spikes in cloud spend, use auto-adjusting budgets to receive alerts when your cost or usage patterns change as a complement to your existing budgets. At the beginning of each new period, AWS Budgets calculates your auto-adjusted budget amount using historical billing data within the specified time range. For example, you can create an auto-adjusting cost budget with a baseline time range of the last six months. In this scenario, if your average spending each budget period in the last six months was $100, your auto-adjusted budget amount in the new period is $100. If AWS Budgets updates your budget amount, all budget alert notification subscribers are notified of the change. This feature saves time because it reduces the need to manually maintain budget limits as your cost and usage patterns change while alerting you to increases in your baseline.
