Calculating Estimated Monthly Savings

Estimated Monthly Savings

Cost Center provides you with the estimated monthly savings for your reference only when handling idle resources. Estimated Monthly Savings is the total estimated monthly cost savings of all resources that can be optimized.

• Estimated Monthly Savings = Estimated Monthly Expenditure – Estimated Monthly Expenditure After Optimization
• Estimated Monthly Expenditure = Monthly amortized cost/Time Range/24 x 730
  • Time Range refers to the number of days during which the resource is using the new billing mode over the last 30 days.
  • Estimated Monthly Expenditure may have slight discrepancies in precision due to amortization calculation.
  • 730 is used as the default number of hours per month.
• Estimated Monthly Expenditure After Optimization: In the case of releasing idle resources, the estimated monthly expenditure after optimization is 0.

Contributory Factors

• Estimated Monthly Savings are calculated based on historical daily expenditures. If there are resources whose validity period is less than one day in the historical time range, Estimated Monthly Savings may be inaccurate.
• Estimated Monthly Savings are calculated based on the amount due with historical commercial discounts applied. If the commercial discounts have changed, Estimated Monthly Savings may be inaccurate.
• Estimated Monthly Savings are calculated based on the assumption that yearly/monthly subscriptions will be renewed. If yearly/monthly subscriptions are not renewed, Estimated Monthly Savings may be inaccurate.
• Estimated Monthly Savings do not take into account the impact of handling fees and coupons. If resources are unsubscribed from based on the optimization recommendations, Estimated Monthly Savings may be inaccurate.

For pay-per-use resources, if a certain amount of usage has been paid for using special products over the last 30 days, Estimated Monthly Savings may be different from the actual savings.

• Over the last 30 days, if the pay-per-use billing is changed to special products and the special products will continue to be used, then Estimated Monthly Expenditure After Optimization is greater than the actual cost and Estimated Monthly Savings are less than the actual costs saved.
• Over the last 30 days, if the billing of using special products is changed to pay-per-use and the pay-per-use billing will continue to be used, then Estimated Monthly Expenditure After Optimization is less than the actual cost and Estimated Monthly Savings are greater than the actual costs saved.

Important Notes

Resource optimization recommendations are not generated in real time for EVS, EIP, and ELB resources. They are updated daily at 00:00:00 (GMT+08:00).

For example, the recommendations you saw at March 10, 2024 00:00:00 GMT+08:00 were generated based on your resource performance during the period from March 08, 2024 12:00:00 GMT+08:00 to March 09, 2024 12:00:00 GMT+08:00.

The cost analysis results (including the monthly amortized costs, estimated monthly savings, and estimated monthly expenditure) were calculated based on the cost data by March 09, 2024 00:00:00 GMT+08:00.
