Pricing for Cloud SQL depends on your instance type:
MySQL Second Generation pricing
Instance pricing for Second Generation is charged for every minute that the instance is running
(the activation policy is set to
ALWAYS). The charge depends on the machine
type you choose for the instance, and the region where the instance is located. Select your
region from the dropdown on the pricing table.
Read replicas and failover replicas are charged at the same rate as stand-alone instances.
*Shared CPU machine types (db-f1-micro and db-g1-small) are not covered by the Cloud SQL SLA.
Storage and Networking Pricing
Storage and networking prices for Second Generation instances depend on the region where the instance is located. Select your region from the dropdown on the pricing table.
Network Egress Pricing
When network traffic leaves a Cloud SQL instance, the charge applied depends on the destination of the traffic, and in some cases, whether a partner is involved.
Internet egress is network traffic leaving a Cloud SQL instance to a client that is not a Google product, such as using a local server to read data from Cloud SQL.
|Compute Engine instances and Cloud SQL cross-region replicas||Within the same region: free
Between regions within North America: $0.12/GB
Between regions outside of North America: $0.12/GB
|Google Products (except Compute Engine and traffic to Cloud SQL cross-region replicas)||
|Internet egress using Cloud Interconnect||$0.05/GB|
|Internet egress (not using Cloud Interconnect)||$0.19/GB|
MySQL Second Generation pricing examples
You can use the Google Cloud Pricing Calculator to get pricing estimates for your Cloud SQL instances. Here are a few example calculations:

MySQL First Generation pricing
For First Generation instances, Google offers two billing
plans: Packages and
Which plan you should select depends on how your database will be used, but generally it is more
economical to use the Package plan if your instance is used for more than 450 hours each month.
If your instance is used sporadically, you can reduce costs by using the Per-use
plan and setting your activation policy to
More details about both plans are given below. You can also get a pricing estimate with the Google Cloud Pricing Calculator.
If you pay in a currency other than USD, the prices listed in your currency on Cloud Platform SKUs apply.
Packages Billing Plan
The following packages are available:
|Tier||CPUs||RAM||Included Storage||Max Storage more info||Charge per Day||Maximum Concurrent Connections|
You can change an instance's tier at any time, with just a few seconds of downtime.
At the end of a billing period, you are charged based on the number of days during which the database exists (measured at US Pacific Time). Storage for backups created using the scheduled backup service is not part of the package limits and is not charged. Use of storage over the included quota is charged at the Per-Use rate ($0.24 per GB per month).
Storage is measured as the filespace used by the MySQL database. The size of all instances is limited to 250GB by default. Note that you only pay for the storage that you use, so you don’t need to reserve this storage in advance. If you require more storage, up to 500GB, contact email@example.com.
A newly created database uses about 270MB of space for system tables and InnoDB logs. If you create a per-use instance but do not use it, you are still charged for the storage cost.
Per-Use Billing Plan
The following resources are available, charged per minute of use:
|D0 Database Instance (0.125GB RAM)||$0.025 per hour|
|D1 Database Instance (0.5GB RAM)||$0.10 per hour|
|D2 Database Instance (1GB RAM)||$0.19 per hour|
|D4 Database Instance (2GB RAM)||$0.29 per hour|
|D8 Database Instance (4GB RAM)||$0.58 per hour|
|D16 Database Instance (8GB RAM)||$1.16 per hour|
|D32 Database Instance (16GB RAM)||$2.31 per hour|
|1GB Storage||$0.24 per month|
- The maximum concurrent connections allowed for each tier is the same as for the Packages Billing Plan.
- Use of instances is charged per minute for periods of continuous use. (see the FAQ for more details).
- Storage is charged by the GB, and measured every
minute so your charges closely follow your usage. Storage charges are incurred whether the
instance is on or off.
- Storage for backups created using the scheduled backup service is not charged.
- A newly created database uses a small amount of space (270MB) for system tables and InnoDB logs. This is included in the charged storage.
- The default and maximum storage for an instance are the same as the Packages Billing Plan (see Storage Size).
- You can change an instance's tier at any time, with just a few seconds of downtime.
|Internet Egress||$0.12 per GB|
Network use is charged for both packages and per-use billing plans. Only internet egress is charged, such as traffic to an admin or reporting tool or application hosted outside of the Google Cloud. Network usage between App Engine applications, Compute Engine, or Cloud Storage and Cloud SQL are not charged.
Cloud SQL supports read replicas where the replica instances are other Cloud SQL instances or external MySQL instances.
- The only extra charge for replicating a Cloud SQL instance to another Cloud SQL instance is the cost of the replica instance.
- The only extra charge for replicating a Cloud SQL instance to external replicas is for the internet egress cost.
For more information about read replicas, see Requirements and Tips for Configuring Replication.
Instance IPv4 addresses
|Instance IPv4 Address||$0.01 per hour idle|
The use of an external IPv4 address for instances on the per-use billing plan is charged at $0.01 per hour for the time that the connection is idle. For example, if your per-use instance is idle, on average, 50% of the time, then an external IP address for the instance would cost $43.83 for one year.
Each Cloud SQL instance has an IPv6 address that you can also use to connect to the instance. The IPv6 address is independent of whether you assign and use an IPv4 address. Use of the instance IPv6 address is not charged. For more information, see Configuring access for IP connections.
