# Astra DB pricing
{: #wxd_astra_db_pp}

Select the appropriate pricing plan for your Astra DB deployment by reviewing the tables provided in this page.

## Astra DB billable meters and measures
{: #wxd_adb_billable_meters}

The following table provides a current list of Astra DB billable meters and their measures. A billable meter is any metered metric on the Astra platform that results in a billable event which deducts the corresponding number of Resource Units (RU) from the customer's total credit balance or gets applied to a credit balance due for pay-as-you-go customers.

| Product or Service | Meter | Measure |
| --- | --- | --- |
| Astra DB on-demand: Reads | Number of writes | Per 1 million |
| Astra DB on-demand: Writes | Number of reads | Per 1 million |
| Astra DB on-demand: Vector dimension reads | Number of reads | Per 1 million |
| Astra DB on-demand: Vector dimension writes | Number of reads | Per 1 million |
| Astra DB provisioned capacity units all types | Number of hours | Per hour |
| Astra DB storage: All types | GB stored | Maximum per month |
| Astra DB data transfer: All types | GB transferred | Total GB transferred |
| Astra DB private link: Active | Hours | Per hour |
| Astra DB private link: Ingress | GB transferred | Total GB transferred |
| Astra DB private link: Egress | GB transferred | Total GB transferred |
