Disks and images pricing

This page describes the pricing information for Compute Engine disks and images. This page does not cover pricing for VM instances, networking, sole-tenant nodes, or GPUs.

Compute Engine charges for usage based on the following price sheet. A bill is sent out at the end of each billing cycle, listing previous usage and charges. Prices on this page are listed in U.S. dollars (USD).

For Compute Engine, disk size, machine type memory, and network usage are calculated in gigabytes (GB), where 1 GB is 230 bytes. This unit of measurement is also known as a gibibyte (GiB).

If you pay in a currency other than USD, the prices listed in your currency on Cloud Platform SKUs apply.

You can also find pricing information with the following options:

Premium images

Certain images available on Compute Engine are considered premium images and incur charges to use. These images include:

  • Red Hat Enterprise Linux (RHEL and RHEL for SAP)
  • SUSE Linux Enterprise Server (SLES and SLES for SAP)
  • Windows Server
  • SQL Server

The price for a premium image depends on which machine type you use. For example, a standard SLES image costs $0.02 per hour to run on an f1-micro instance, but the same image costs $0.11 per hour to run on an n1-standard-8 instance. The prices for premium images are the same worldwide and do not differ based on zones or regions.

All prices for premium images are in addition to charges for using a machine type. For example, the total price for using an n1-standard-8 instance with an SLES image is the sum of the machine type cost and the image cost:

n1-standard-8 cost + SLES image cost = $0.379998 + $0.11 = $0.49 per hour

Preemptible instances do not reduce the costs of premium images and do not change the way that you are billed for the use of those images. If Compute Engine terminates a preemptible instance that runs a premium image, you are billed for that image as if you terminated the instance yourself. The charges for minimum usage still apply, and bills for premium images are still calculated by rounding up to the nearest usage increment.

Ubuntu Pro

The following sections outline the license cost for using Ubuntu Pro images on Compute Engine. When running VMs that use the premium Ubuntu Pro images, you incur license cost in addition to the regular cost of running the VM. For VM pricing, see VM instances pricing.

The license cost for running Ubuntu Pro VMs, per hour, on Compute Engine is calculated as follows:

(license cost for RAM per GB per hour) + (license cost for vCPU per hour)

Memory

License cost for memory is charged at one flat rate of $0.000127 per GB/hour in USD.

vCPU

License cost for vCPU varies by the number of vCPUs that the Ubuntu Pro VM has. The following table summarizes the license cost per hour in USD.

Number of vCPUs License cost (USD)/hour
1 $0.001660
2 $0.002971
4 $0.005545
6 - 8 $0.009970
10 - 16 $0.018063
18 - 48 $0.033378
50 - 78 $0.060548
80 - 96 $0.077871
98 - 222 $0.102401
>222 $0.122063

Example

For example, if your Ubuntu Pro VM has 64 GB RAM and 16 vCPUs, the license cost is calculated as follows:

Hourly license cost per VM = (0.000127 * 64) + (0.018063) = $0.026191
Monthly license cost (31 day month) per VM = 0.026191 * 744 = $19.486104

Ubuntu pro with attached GPUs license costs

The following sections outline only the license cost for using Ubuntu Pro images with attached GPUs on Compute Engine. When running VMs that use the premium Ubuntu Pro images with attached GPUs, you incur license cost for the premium image and a GPU license in addition to the regular cost of running the VM and the cost of the attached GPU.

The license cost of running Ubuntu VMs with attached GPU, per hour, is calculated as follows:

(license cost for RAM per GB per hour) + (license cost for vCPU per hour) + (license cost for GPU per hour)

The following table summarizes the per GPU license rates per month in USD for Ubuntu Pro VMs. The license fee varies based on the number of GPUs attached to the VM but is the same for all GPU models that are available on Compute Engine.

Number of GPUs License cost (USD)
1 $0.035
2 $0.066
4 $0.120
8 $0.208
>8 $0.300

Example

For example if your Ubuntu Pro VM has 64 GB RAM, 16 vCPUs and 4 GPUs attached, the per hour license cost is calculated as follows:

Hourly license cost per VM  = (0.000127 * 64) + (0.018063) + (0.120) = $0.146191
Monthly license cost (31 day month) per VM = 0.146191 * 744 = 108.766104

Windows Server images

Public images for several versions of Windows Server are available in either the Server Core configuration or the Server with Desktop Experience configuration. Both configurations are available at the following prices:

  • $0.023 USD/hour for f1-micro and g1-small machine types
  • $0.046 USD per core/hour for all other machine types

Standard machine types, high-CPU machine types, and high-memory machine types are charged based on the number of CPUs. For example, n2-standard-4, n2-highcpu-4, and n2-highmem-4 are machine-types with 4 vCPUs, and are charged at $0.184 USD/hour (4 x $0.046 USD/hour).

Windows Server images are charged a 1 minute minimum. After 1 minute, Windows images are charged in 1 second increments.

For information about licensing for Windows Server images, see Microsoft licenses.

SQL Server images

SQL Server images incur costs in addition to the cost for Windows Server images and the cost for the selected machine type.

  • $0.399 USD per core/hour for SQL Server Enterprise
  • $0.1645 USD per core/hour for SQL Server Standard
  • $0.011 USD per core/hour for SQL Server Web
  • No additional charge for SQL Server Express

Microsoft SQL Server licensing requires a core license to be assigned to each virtual CPU on your virtual machine instance, with a four core minimum for each instance. Instances with fewer than 4 vCPUs will be charged for SQL Server at 4 x $0.1645 USD/hour ($0.658 USD/hour) to comply with these requirements. For instances with 4 or more vCPUs, Compute Engine charges you for Microsoft SQL Server licenses in increments of 2. However, instances with a custom machine type will be charged for the number of SQL Server licenses that is equal to the number of vCPUs.

Google recommends that you not use SQL Server images on f1-micro or g1-small machine types based on Microsoft's minimum hardware and software recommendations.

Unlike other premium images, SQL Server images are charged a 10 minute minimum. After 10 minutes, SQL Server images are charged in 1 minute increments.

For information about licensing for SQL Server OS images, see Microsoft licenses.

Disk pricing

Each VM instance has at least one disk attached to it. Each disk incurs a cost, described in this section. In addition, if you use snapshots, there are separate snapshot charges.

All disk-related charges in this section are prorated based on a granularity of seconds. This includes all persistent disk types, snapshot storage, and local SSD pricing.

For example, based off US pricing, a 200 GB standard persistent disk volume would cost $8.00 for the whole month. If you only provisioned a 200 GB volume for half a month, it would cost $4.00. Likewise, a 200 GB SSD persistent disk volume would cost $34.00 for the whole month. If you only provisioned a 200 GB volume for half a month, it would cost $17.00.

Provisioned disk space includes all used and unused space. If you provision a 200 GB disk, you are billed for that entire disk space, regardless of how you use it, until you relinquish it.

Persistent disk pricing

Persistent disks are priced by the amount of provisioned space per disk. Persistent disk I/O operations are included in the charges for provisioned space and persistent disk performance grows linearly by the size of the persistent disk volume, so you might want to create a larger or smaller persistent disk to account for your I/O needs. For more information, see the persistent disk specifications.

After you successfully delete a persistent disk, you are no longer charged for that disk.

Persistent disk snapshots

All snapshots that exist in your project incur monthly storage fees. Whenever you create or restore a snapshot, you might also incur network fees based on the storage location of the snapshot.

Storage charges for snapshots

A snapshot incurs monthly storage charges as long as it exists in your project. Persistent disk snapshots only incur charges for the total size of the snapshot. For example, if you only used 2 TB of disk space on a 5 TB persistent disk, your snapshot size is charged for 2 TB, rather than the full 5 TB of provisioned disk space. Compute Engine also provides incremental snapshots, which contain only the data that has changed since the previous snapshot, providing for a generally lower cost for snapshot storage. When you delete a complete or incremental snapshot, some of its data may move to the next incremental snapshot in the snapshot chain. This additional data increases the storage cost because you are using more space in the storage system.

Note that snapshot storage charges, like disk-related charges, are prorated based on a granularity of seconds.

Network charges for snapshot creation and restoration

Network charges for snapshot creation and restoration follow standard Cloud Storage network pricing, but are billed under Compute Engine.

A persistent disk can be stored in a Compute Engine zone or region, but a snapshot is stored in either a Cloud Storage region or multi-region. Note that Compute Engine regions and Cloud Storage regions have similar names. Each multi-region contains multiple regions, and each region contains multiple zones. For example, the zone europe-north1-a is part of the europe-north1 region, and europe-north1 is part of the eu multi-region.

If you create or restore a snapshot that is stored in a location that is different from the location of your disk, the data travels over the network between those locations and may incur network fees. Snapshots incur the same fees as Cloud Storage egress.

For example, if your disk is located in the us-central1 region, and you want to create a snapshot in europe-west1, you will incur a cross-regional network charge.

Local SSD pricing

Local SSD devices are charged for the amount of provisioned space per device for the lifetime of the instance it is attached to. The prices for local SSDs differ depending on the region. For example, in the Iowa, Oregon, Taiwan, and Belgium regions, local SSDs cost $0.080 per GB per month. As mentioned earlier, local SSD charges are prorated to a granularity of seconds.

Because local SSDs can only be purchased in 375 GB increments, the cost-per-month for a single device is the monthly rate multiplied by 375 GB. For example, at a monthly rate of $0.080, the cost would be $30.00 per device per month. Actual data storage and usage are included in that price and there is no additional charge for local traffic between the virtual machine and the local SSD device.

You can reserve local SSDs in a specific zone, with or without a commitment. Without a commitment, you pay normal on-demand prices. For committed-use discounted pricing for local SSDs, a reservation must be created when purchasing the commitment. For more information, see Reserving zonal resources.

Custom image storage

If you import or create custom images in Compute Engine, these images incur a storage cost. The cost of these custom images depends on the location where you store the image. There are no network transfer fees for creating images, nor for creating disks from images.

Machine image

The cost of using a machine image depends on the size of the machine image, and the location where it is stored.

There is also a one time network transfer fee if you are storing a machine image in a different location than the source instance, or if you create an instance from a machine image that is stored in a different location from the instance.
