Pricing

This document explains Cloud Spanner pricing details.

You can also use the Google Cloud Platform Pricing Calculator to estimate the cost of using Cloud Spanner.

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

Cloud Spanner pricing overview

When you use Cloud Spanner, you are charged for the following:

  1. The number of Cloud Spanner nodes in your instance.

    During each hour, Cloud Spanner keeps track of how many Cloud Spanner nodes exist in your instance. You are charged each hour for the maximum number of nodes that exist during that hour, multiplied by the hourly rate. As a result, any nodes that you provision will be billed for a minimum of one hour.

  2. The amount of storage that your tables and secondary indexes use.

    Cloud Spanner charges you for the average amount of data in your Cloud Spanner tables, secondary indexes, and metadata over a one-month period, multiplied by the monthly rate.

  3. The amount of network bandwidth used.

    Some types of network egress traffic, such as application reads of Cloud Spanner databases, are subject to bandwidth charges, as shown below. There are no bandwidth charges for Cloud Spanner replication or network ingress traffic.

Project storage usage and bandwidth usage are calculated in gigabytes (GB), where 1 GB = 230 bytes.

Project storage and bandwidth usage charges accrue daily. You can view unbilled usage at any time on the Google Cloud Platform Console.

The following tables show the pricing for each component of Cloud Spanner.

Inter-continental egress At Internet egress rate
If you pay in a currency other than USD, the prices listed in your currency on Cloud Platform SKUs apply.

Internet egress rates

For instances with regional configurations, internet egress rates are as shown below.

For instances with multi-region configurations, internet egress is charged as follows:

  • Egress from read-write transactions is always charged based on the egress cost from the default leader region.
  • Egress from other reads is charged based on the egress cost from whichever region in the multi-region configuration is closest to the client. For example, assuming that you are using the multi-region configuration nam-eur-asia1:

    • For clients in us-central1, egress is free, because the region is part of the multi-region configuration.
    • For clients in us-west1, egress is charged from us-central1, which is the closest region in the multi-region configuration.
    • For clients in asia-south1, egress is charged from asia-east1, which is the closest region in the multi-region configuration.

Iowa (us-central1) Los Angeles (us-west2) Northern Virginia (us-east4) Oregon (us-west1) South Carolina (us-east1) Montréal (northamerica-northeast1) Belgium (europe-west1) Finland (europe-north1) Netherlands (europe-west4) Hong Kong (asia-east2) Mumbai (asia-south1) Singapore (asia-southeast1) Taiwan (asia-east1) Tokyo (asia-northeast1)

Database export and import pricing

There are no additional charges from Cloud Spanner for use of the export or import tools; you pay the standard rates for data storage when you import a database to Cloud Spanner. However, there are other potential charges associated with importing and exporting databases:

  • You will be charged the standard rates for Cloud Dataflow batch workers when you run an export or import job. The total charge will depend on the amount of data being imported or exported as well as performance factors. For example, if your Cloud Spanner instance is already under heavy load, import and export jobs might take longer, resulting in a larger overall charge for Cloud Dataflow workers.

  • If you run an import job in a region that does not overlap with your Cloud Storage bucket configuration, you pay Cloud Storage's standard rates for network egress. To minimize charges, ensure that you choose a region for your import job that overlaps with your bucket configuration. See Choosing an import region for more details.

  • If you run an export job in a region that does not overlap with your Cloud Spanner instance configuration, you pay the standard rates for network egress. To minimize charges, ensure that you choose a region for your export job that overlaps with your instance configuration. See Choosing an export region for more details.
