Cloud SQL Instance vCPU, RAM and Storage

Cloud SQL bills vCPU, memory, and storage as separate SKUs, plus backups.

Two things drive surprises: high availability uses HA rates, about twice the zonal rate for vCPU, memory and storage, and storage auto-grows and stays grown until someone shrinks it.

Billed: Separate per-vCPU-hour, per-gibibyte-hour, and per-gibibyte-month SKUs. High availability uses HA rates, about twice the zonal rate for vCPU, memory and storage.

What triggers this charge

Every second an instance runs. Stopping it ends the vCPU and memory charges, but storage and IP addresses keep billing.
High availability, which provisions a standby and bills it. Backups are not billed at the HA rate.
Extended support: instances on a database major version past its end of life carry an extra extended-support charge until they are upgraded.
Automatic storage increases, which do not reverse on their own. A manual storage shrink exists, but it takes the instance offline while it runs and is not available on shared-core instances.
Backups and point-in-time recovery logs, billed separately from instance storage.

How to reduce it

Right-size, then check HA is actually required

HA on a development or reporting instance roughly doubles its vCPU, memory and storage charges for an availability guarantee nobody asked for.

Watch automatic storage growth

It only goes up by itself. A runaway table or an unrotated log raises the floor of your storage bill until someone runs a storage shrink, which needs downtime, or migrates to a smaller instance. Set an automatic storage increase limit.

Buy committed use discounts for steady instances

Cloud SQL commitments discount vCPU and memory, and databases are the most predictable workload most organizations run. They do not apply to storage, network, licenses, extended support or shared-core instances.
