How to calculate usage fees

[Update: September 1, 2018]

This page explains how to calculate usage fees for SAKURA Cloud servers, etc.

1. Image of server billing

Server: After the virtual server has been created, billing starts from the time of startup and then stops when the server is stopped.
Disk: After the disk has been created, billing starts for the disk and then stops when the disk is deleted.

Methods for calculating the billing amount for servers and related cautions

  • When startup is defined as operation of the customer virtual server on the cloud infrastructure, billing is applied to the total startup (operation) time.
  • The startup time (applicable billing time) does not match the time of power source operation by the customer at the control panel, API, etc., and does not match the time at which the shutdown command was executed at the virtual server.
  • If you want to confirm the exact time for startup/stoppage of the virtual server, please refer to the [State Transition (provisional name)] log that is displayed in the event log. For details, please refer to :doc: Event log: Event list </controlpanel/eventlog/detail>.

Regarding startup time during the occurrence of host server failure

  • When a failure has occurred at the host server for the customer virtual server, the automatic recovery program causes re-execution to be performed at the normal host server. For details on behavior, please refer to FAQ: How is operation performed when a fault occurs at the host server?.
  • During the period from the occurrence of a failure until recovery, the customer virtual server where the failure occurred is treated as being in the stopped state and is excluded from billing time.
  • Billing is resumed at the time that the customer virtual server is re-executed at a normal host server. In some cases, the time of startup after failure recovery occurs at an earlier time than the failure recovery time that is listed on our support website or the recovery completion time that is listed in the email which is sent to the customer at the time of failure occurrence.

2. Changing the server plan

The total usage fees for all server plans are billed.

3. Method for calculating fees (usage-based fee)

Settings for hourly rates, daily rates, or monthly fees are specified in SAKURA Cloud.

  • 10 hours of hourly rates = 1 day of daily rates
  • 20 days of daily rates = 1 month of monthly fees

At the end of the month, fees for each contract are calculated in seconds from the start of the contract until cancellation of the contract. The following items are calculated from the usage time.

  • ①時間割料金+日割料金
  • ②月額料金


The billing amount is determined from the smaller of (1) and (2).

*For servers, billing is based on the total startup (operation) time for one month, not on the period from the start to finish of the contract. For details, please refer to the section [1. Image of server billing] above.
*Depending on the contract, hourly rates may not be set for some products. In that case, the total of daily rates and monthly fees are compared, and the smaller is used as the billing amount.
*A rough estimate for the timing of switch from hourly rates to daily rates “and from daily rates to monthly fees is listed below. However, smallest amount of fees is always used so that customers are not placed at a disadvantage.

4. Method for calculating fees (monthly fee system)

SAKURA Cloud contains some resources for which hourly rates/daily rates are not set, and only monthly fees are used.

  • License expenses [Windows Server Plan (for RDS)]
  • License expenses [Windows Server Plan (for RDS + MS Office)]

*License expenses [Windows Server Plan (Datacenter Edition)]: License expenses are set as hourly rates or daily rates.

  • Prefix [router + switch]

When resources (including items for which monthly fees are incurred at the time of creation) are repeatedly created and deleted, monthly fees are incurred for each instance of creation. Please be careful when handling these resources.

(Example) Case in which Windows Server (for RDS) is created 3 times in one month
Case in which servers for Windows Server (for RDS) are repeatedly created/deleted. License expenses for Windows Server (for RDS) are billed as monthly fees at the time of creation. Therefore, license expenses are billed for three servers.

5. Discount passport

The discount passport is a system for discounting server fees assuming long-term usage. This discount applies only to server fees. Disk fees are not applicable.
