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.

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 and secondary indexes over a one-month period, multiplied by the monthly rate.

  3. The amount of network bandwidth used.

    Some types of network egress traffic are subject to bandwidth charges, as shown below. There is no bandwidth charge for 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.
