## UnderstandData Connectbilling

Firebase Data Connectconsists of two billable components:

- TheData Connectservice itself
- The Cloud SQL for PostgreSQL instance that contains your project data.

If you integrate with Vertex AI, you are billed for vector embeddings.

### Data Connectservice pricing

- Network egress has no cost up to 10 Gib/month; more than 10 Gib/month, egress is charged at[Google Cloud Internet Data Transfer Rate Premium Tier pricing](https://cloud.google.com/vpc/pricing#internet_egress).

- Operations (queries or mutations) executed from clients incur no cost up to 250,000 operations per month; more than 250,000, operations are charged at $4.00 per million.

  | **Note:** The price is per operation and is not related to the amount of data read from the database; there is no "per row read" fee. EachData Connectoperation can perform efficient, complex, multi-table queries or multi-row updates.

### Cloud SQL no cost trial

If you accept the default configuration when you provision a Cloud SQL for PostgreSQL instance, you will be qualified for a no cost trial for 3 months.

- 5 free trials are available per billing account.
- 1 free trial Cloud SQL for PostgreSQL instance per project, although you can have multiple non-free instances within that project.
- The default configuration of your Cloud SQL for PostgreSQL instance is equivalent to a[db-f1-micro instance](https://cloud.google.com/products/calculator?dl=CiRhNDU2NjBmOC1lODJiLTQ0NTctOTliNy00ZmEyZDAyYWFjYTMQBxokODA2Q0I5NzUtMTNEMC00QURFLTg5MUUtMDI2M0VGNzFBMDI0&e=13802955)that has 1 vCPU, 10 GB of storage, 628.74 MB of memory.

During the no cost trial, you can add computing resources to your Cloud SQL instance, set up a private IP for your instance, and create a read replica for your instance, at which point you will be billed according to[Cloud SQL pricing](https://cloud.google.com/sql/docs/postgres/pricing).

After 3 months, pricing starts as low as $9.37 / month. Pricing varies based on regions and configurations. See[Cloud SQL pricing](https://cloud.google.com/sql/docs/postgres/pricing).
| **Note:** Existing customers who participated in the Public Preview trials will automatically roll into the 3 month no cost trials when General Availability starts.
| **Note:** If you delete your no cost trial instance, your no cost trial for the associated Firebase project will terminate immediately.

### Vertex AI embedding generation

UsingData Connectwith[Vertex AI](https://cloud.google.com/vertex-ai)will incur standard usage charges from Vertex AI for embedding generation.

## Manage spending

To monitor yourData Connectusage, to access an overall view of all service activity, and links to analyze individual service activity, open the[Data Connectproduct page](https://console.firebase.google.com/project/_/dataconnect). Use the dashboards to gauge your usage over different time periods.

To track yourData Connectcosts, create a monthly budget in theCloudconsole. Budgets won't limit your usage, but you can set alerts to notify you when you're approaching or exceeding your planned costs for the month.

To set a budget, in theCloudconsole, go to the[Billing](https://console.cloud.google.com/billing/)section and create a budget for yourCloud Billingaccount. You can use the default alert settings or modify the alerts to send notifications at different percentages of your monthly budget.
