    Cloud Enterprise Network:Purchase and apply a savings plan

    Last Updated:Jun 18, 2026

    You can calculate the spending commitment based on the data transfer volume of your Enterprise Edition transit routers, then purchase a savings plan to reduce data transfer costs.

    Calculate the spending commitment

    Transit router savings plans are ideal for stable traffic with flat peak traffic and long-term usage. Observe the traffic trends of your Enterprise Edition transit routers, determine a suitable traffic tier, and then calculate the spending commitment.

    Note

    • The unit prices and discounts in the following examples are for reference only. The pricing and discount information on the buy page shall prevail.

    • For easier calculation, numbers are rounded up or down to two decimal places. The results on the buy page shall prevail.

    For example, a company deployed an Enterprise Edition transit router in each of the China (Hangzhou), China (Shenzhen), and China (Zhangjiakou) regions, all forwarding network traffic. The following figure shows the traffic trends of the transit routers over 7 days. Assume that the commitment term is 1 hour. The following figure shows the total data transfer of all transit routers within a commitment term. 流量趋势.png

    The traffic trends show that the transit routers forward at least 250 GB of data during each commitment term. The company can use a savings plan to offset the fee for at least 250 GB of data transfer per commitment term. Assume that the company chooses 100% upfront payment when purchasing the savings plan.

    • The minimum spending commitment for each commitment term is calculated as follows: 250 GB × USD 0.02/GB × 0.612 = USD 3.06. Since the spending commitment must be an integer, this value is rounded to USD 3.

      USD 3/0.612/USD 0.02 per GB = 245.10 GB. The savings plan can offset the fee for 245.10 GB of data transfer during each commitment term.

      Note

      If the calculation result is not an integer, round it up or down to the nearest integer.

      In this example, if the spending commitment is rounded up to USD 4, then: USD 4/0.612/USD 0.02 per GB = 326.80 GB. The savings plan can offset the fee of 326.80 GB of data transfer during each commitment term. The preceding figure shows that the amount of data transfer during each commitment term is less than 270 GB. The fee of 270 GB of data transfer is closer to USD 3 than USD 4. Fewer resources are wasted if USD 3.06 is rounded down to USD 3.

    • The company saves at least 245.10 GB × USD 0.02/GB - USD 3 = USD 1.90 each commitment term.

    • Assume that a total of 44,239 GB of data is forwarded within 7 days. Using this volume to project the annual data transfer, the total data transfer fee over 365 days can be reduced by 36.07%.

      • The savings plan helps the company save at least USD 1.90 × 24 hours/day × 365 days = USD 16,644 per year.

      • Without a savings plan, the company's annual data transfer fee would be44,239 GB × USD 0.02/GB × (365 days ÷ 7) = USD 46,134.96.

      • The projected annual savings percentage for data transfer fees is USD 16,644 ÷ USD 46,134.96 = 36.07%.
