What is the maximum number of months that AWS cost Explorer will forecast?

You create a forecast by selecting a future time range for your report. For more information, see . The following section discusses the accuracy of the forecasts created by Cost Explorer and how to read them. Show
A forecast is a prediction of how much you will use AWS services over the forecast time period that you selected. This forecast is based on your past usage. You can use a forecast to estimate your AWS bill and set alarms and budgets for based on predictions. Because forecasts are predictions, the forecasted billing amounts are estimated and might differ from your actual charges for each statement period. Like weather forecasts, billing forecasts can vary in accuracy. Different ranges of accuracy have different prediction intervals. The higher the prediction interval, the more likely the forecast has a wider range. For example, suppose that you have a budget set to 100 dollars for a given month. An 80% prediction interval might forecast your spend between 90 and 100, with a mean of 95. The range in the prediction band is dependent on your historical spend volatility, or fluctuations. The more consistent and predictable the historical spend, the narrower the prediction range in forecast spend. Cost Explorer forecasts have a prediction interval of 80%. If AWS doesn't have enough data to forecast an 80% prediction interval, Cost Explorer doesn't provide a forecast. This is common for accounts that have less than one full billing cycle. Reading forecastsHow you read the Cost Explorer forecasts depends on the type of chart that you're using. Forecasts are available for both line charts and bar charts. The 80% prediction interval appears differently on each type of chart:
If you receive discounts, we encourage you to use Show net unblended costs when forecasting your monthly costs to include discounts. Unblended costs don't include discounts. Instead, they separate discounts into their own line item. For more information about different costs, see Cost Explorer Advanced Options. If you use the consolidated billing feature in AWS Organizations, the forecasts are calculated with the data from all the accounts. If you add a new member account to an organization, forecasts don't include that new member account until the new spending patterns of the organization are analyzed. For more information about consolidated billing, see Consolidated billing for AWS Organizations.

Type: String Valid Values: Required: Yes AWS Cost Explorer always returns the mean forecast as a single point. You can request a prediction interval around the mean by specifying a confidence level. The higher the confidence level, the more confident Cost Explorer is about the actual value falling in the prediction interval. Higher confidence levels result in wider prediction intervals.

Cost Explorer allows you to choose custom date ranges to analyze up to 12 months in the past, but you can also select dates up to 12 months in the future, to get forecasted ranges for your cost.
How far back does AWS cost Explorer go?After you enable Cost Explorer, AWS prepares the data about your costs for the current month and the last 12 months, and then calculates the forecast for the next 12 months.
What is forecasted amount in AWS?You can use a forecast to estimate your AWS bill and set alarms and budgets for based on predictions. Because forecasts are predictions, the forecasted billing amounts are estimated and might differ from your actual charges for each statement period. Like weather forecasts, billing forecasts can vary in accuracy.
Which AWS service should be used to get a prediction of the next month's bill for the services you use?AWS Cost Explorer enables you to view and analyze your AWS Cost and Usage Reports (AWS CUR). You can also predict your overall cost associated with AWS services in the future by creating a forecast of AWS Cost Explorer, but you can't view historical data beyond 12 months.
