Contributory Factors

Data Precision

• Original costs and billed amounts are calculated with the same precision.
• Amortized costs may have slight precision differences. They need to be rounded off as required:
  • The amounts displayed on the Cost Center pages are rounded off to the 2nd decimal place.
  • The amounts included in exported cost details are calculated to the 8th decimal place.
• The costs for the following orders need to be amortized:
  • Yearly/monthly subscriptions
  • Reserved instances
  • Monthly-settled CDN services (if enabled)

Data Delay

Original costs: There is an appropriately one-hour delay before data from Billing Center shows up as original costs for the current month in Cost Center. To view the exact amounts, see the final bill that will be generated on the 3rd day of the following month. The original costs are available for viewing and exporting at 12:00 noon on the 4th day of the following month.

Amortized costs: They are not calculated in real time. Cost Center refreshes your amortized costs once every 24 hours, and it may take longer than 24 to 48 hours for some data to be displayed. The current month costs of monthly-settlement cloud services, such as CDN and VPC, are available for viewing or export after 12:00 noon on the 4th day of the following month.

Forecasted Data

• On the Cost Analysis page, daily/monthly forecasts marked with ** are only estimates. Forecasts are produced based on the historical data you specified. Daily forecasts currently do not take into account periodicity and differ from the actual data in the forecast period covered. They are for reference only.
• Forecasted costs are estimated based on your historical expenditures over at least the last three months. If there is not enough historical data, forecasts cannot be produced.
