The billing for Azure Storage usage depends on the used storage account. Also, storage costs are based on these determinants:

• Location: This describes the geographical region in which the account is based.
• Storage capacity: This refers to how much of the storage account is used to store data.
• Account type: Based on the usage of either the general-purpose storage account or the Blob storage account; the account type affects the billing. When using a Blob storage account, the access tier also defines the billing model for the account.
• Storage transactions: Transactions are all read and write operations to Azure Storage.
• Replication scheme: This describes the number of copies of your data and where they are stored.
• Data egress: This is the data that is transported out of an Azure region. This usually happens when the data is obtained by an application that is located in another region or in an on-premises location. If data egresses from Azure, charges apply.
