Enhanced 95th Percentile Billing

Last updated: 2024-12-24 19:25:52
    This document provides the billing description, billing formula, bandwidth unit prices, and billing example for static single-line bandwidth packages in the pay-as-you-go - enhanced 95th percentile billing mode.
    Note:
    Currently, a static single-line bandwidth package is supported only in Guangzhou, Shanghai, Beijing, Chengdu, Chongqing, Nanjing, Jinan, Hangzhou, Fuzhou, Wuhan, Shijiazhuang, Changsha, Zhengzhou, Shenyang, Xi'an, and Hefei. For other regions, refer to the console page. If you need to try it out, contact your business manager to apply for activation.
    For static single-line bandwidth packages in the pay-as-you-go - enhanced 95th percentile billing mode, the bandwidth cap can be set within the range of 300-5000 Mbps.
    Static single-line bandwidth packages support multiple network egresses in some regions. EIPs from different network egresses can be added only to the corresponding bandwidth packages.
    Bill-by-CVM accounts do not support the pay-as-you-go - enhanced 95th percentile billing mode. To confirm your account type, see Checking Account Type.
    When a bandwidth package is activated, the estimated fees for one settlement cycle are frozen based on your selected bandwidth cap, unit price, and freezing ratio (60% for static single-line bandwidth packages in the enhanced 95th percentile billing mode). If your account balance is less than the frozen fees, activation will not be possible. For details, see Frozen Funds.

    Billing Description

    Billing time
    Bills are generated on the first or second day of every month. You can view the specific billing time in the Billing Center. For details, see Bill Description.
    Settlement time
    Fees are settled on a monthly basis and automatically deducted from your account balance.
    Settlement scope
    Each bandwidth package is specific to a region and a network egress. It can only include EIP instances from the same region and network egress.
    Usage details
    You can view minute-level usage details of a bandwidth package. For details, see Downloading Usage Details.
    Peak bandwidth
    Peak bandwidth for a single instance: The bandwidth cap set when you create a bandwidth package.
    Total bandwidth in a single region: For bandwidth limits of different line types, see Bandwidth Package Use Limits.

    Billing Formula

    Frozen fees for activation = Bandwidth unit price (USD/Mbps/month) x Bandwidth cap (Mbps) x Freezing ratio (60%) x Billing cycle (1 month)
    Bandwidth package fees = MAX (Monthly peak bandwidth x Valid days/Days of the billable month, Monthly base bandwidth x Package duration/Days of the billable month) x Bandwidth unit price
    Monthly peak bandwidth: An average value is calculated separately for the inbound and outbound bandwidth every 5 minutes and the higher value is taken as one valid sample point of peak bandwidth. There are 288 sample points every day. After they are sorted in descending order, the fifth highest value is taken as the daily peak bandwidth. On the settlement day, all the daily peak bandwidth values are sorted in descending order and the average of the top 5 daily peak values is taken as the monthly peak bandwidth.
    Daily base bandwidth: The daily base bandwidth is calculated by multiplying the daily bandwidth cap by the base ratio (20% by default).
    Monthly base bandwidth: The monthly base bandwidth is an average value calculated by dividing the sum of all daily base bandwidth values by the package duration. You can adjust the bandwidth cap of the instance as needed for the package duration, so the daily base bandwidth values may vary.
    Valid days: Number of days with the bandwidth greater than 1 Kbps.
    Package duration: Number of calendar days for the duration (from creation to deletion) of the bandwidth package.
    Days of the billable month: Number of calendar days in the month when the bandwidth package is used.

    Billing Example

    Assume that you created a static single-line CMCC bandwidth package in the pay-as-you-go - enhanced 95th percentile billing mode in Beijing on June 10 (the billable month included 30 days) and deleted it on June 21. For the package duration, the bandwidth cap was 500 Mbps, the base ratio was 20%, and the bandwidth unit price was 6.30 USD/Mbps/month. According to the enhanced 95th percentile billing mode, the fees you need to pay on the billing day are calculated as follows:
    Assume that there were 6 days with actual bandwidth greater than 1 Kbps for the package duration. The bandwidth package existed for 12 days and the monthly peak bandwidth was 80 Mbps. Then for the month:
    Monthly peak bandwidth = 80 Mbps
    Daily base bandwidth = 500 Mbps × 20% = 100 Mbps
    Monthly base bandwidth = 100 Mbps
    Bandwidth package fees = MAX (80 × 6/30, 100 × 12/30) × 44 = MAX (16, 40) × 6.30 = 252 USD
