Prices are estimates only and are not intended as actual price quotes. Actual pricing may vary depending on the type of agreement entered with Microsoft, date of purchase, and the currency exchange rate. Prices are calculated based on US dollars and converted using London closing spot rates that are captured in the two business days prior to the last business day of the previous month end. If the two business days prior to the end of the month autumn on a bank holiday in major markets, the rate setting day is generally the day immediately preceding the two business days. This rate applies to all transactions during the forthcoming month. Sign in to the Azure pricing calculator to see pricing based on your current programme/offer with Microsoft. Contact an Azure sales specialist for more information on pricing or to request a price quote. See frequently asked questions about Azure pricing.

Azure Cosmos DB pricing model

Azure Cosmos DB bills for three different types of usage: compute, storage and bandwidth. The tabs below describe each compute pricing model in greater detail with its accompanying storage and bandwidth pricing models.

Once a compute pricing model and API are chosen, they cannot be changed.

Compute Pricing:

Request Unit (throughput): Azure Cosmos DB bills using Request Units (RU) measured per second (RU/s). Request Units are a proxy for compute, memory and IO used to process database operations and are billed across all selected Azure regions for your Azure Cosmos DB account.

Options for throughput include: Standard Provisioned throughput, Autoscale provisioned throughput and Serverless.

Applicable APIs: NoSQL, MongoDB (RU), Cassandra, Gremlin, and Table.

vCore: Azure Cosmos DB bills for vCores (compute and memory) per node to process database operations and are billed on the size and number of nodes provisioned.

Available APIs: PostgreSQL and MongoDB (vCore).

Storage Pricing:

Consumed Storage: Azure Cosmos DB bills for consumed storage per GB fractions per container/collection/table/graph per region. Consumed storage includes all transactional and analytical data and indexes, and backups.

Applicable APIs: NoSQL, MongoDB (RU), Cassandra, Gremlin, and Table.

Disk Storage: Azure Cosmos DB bills for disks provisioned for each node by storage size.

Applicable APIs: PostgreSQL and MongoDB (vCore).

Bandwidth Pricing:

Data Egress: Azure bills for data that egresses the Azure cloud or transits the Azure WAN across regions or availability zones.

Applicable APIs: All.

Azure Cosmos DB for MongoDB (vCore) is now Azure DocumentDB (with MongoDB compatibility). See the Azure DocumentDB pricing page for pricing.
