For every Cost Report, Vantage generates a forecast that projects where your costs are expected to be by the end of the current month. You can also view projected costs, several months ahead. Vantage uses a time-series model to generate these forecasts and will run through all available data ingested into the platform on a per-service basis (e.g., EC2, RDS). These costs are forecasted into the future, taking into account seasonality or one-off spikes.

View a Forecast on a Cost Report

To view a forecast on a Cost Report, create a new Cost Report and save it. After you create a new Cost Report, a message is displayed that indicates the forecast is generating. The processing time depends on the amount of data contained in the filtered report, but it usually takes less than 10 minutes.
If you add additional filters to an existing report, you need to save the report again for the new forecast to generate. Forecasts are generated based on saved data.
The forecast for the rest of the current month is displayed, by default, on the chart. Forecasts are available on line charts and bar charts. On line charts, forecasts are available for all date binning options. For bar charts, you can view forecasts for day, week, and month date binnings. The forecast includes an upper-expected band and a lower-expected band, with a median forecast that is in the middle of these two ranges. This forecast is updated daily as new cost data arrives. To view a future forecast, open the date picker to the top right of the chart.
  1. On the left, under Forecast Periods, select either Next Month, Next 3 Months, or Next 6 Months.
  2. Click Apply. Change to either the bar or line chart view to see a forecast.
