Answer 1

Hi,

Niharika Siddana

Thanks for reaching out to Microsoft Q&A.

The cost to store data is as below

You can calculate your storage costs by multiplying the size of your data in GB by the storage price of the chosen access tier. For example (assuming sample pricing), if you plan to store 10 TB of blobs in the cool access tier, the capacity cost is $0.0115 * 10 * 1024 = $117.78 per month.

Depending on how much storage space you require, it might make sense to reserve capacity at a discount. You can reserve capacity in increments of 100 TB and 1 PB for a 1-year or 3-year commitment duration. Reserved capacity is available only for data stored in the hot, cool, and archive access tiers.

Using the Sample prices that appear in this article, the following table compares the pay-as-you-go and reserved capacity cost of storing 100 TB (102,400 GB) of data.

Expand table

Calculation	Hot	Cool	Archive
Monthly price for 100 TB of storage	$2,130	$963	$205
Monthly price for 100 TB of storage	$2,130	$963	$205
Monthly price for 100 TB of storage (one-year reserved)	$1,747	$966	$183
Monthly price for 100 TB of storage (three-year reserved)	$1,406	$872	$168

To calculate the point at which reserved capacity begins to make sense, divide the cost of reserved capacity by the pay-as-you-go rate. For example, if the cost of 1-year reserved capacity for cool tier storage is $966 and the pay-as-you-go rate is $0.0115, then the calculation is $966 / $0.0115 = 84,000 GB (roughly 82 TB). If you plan to store at least 82 TB of data in the cool tier for the entirety of the reservation period, then reserved capacity begins to make sense. The following table calculates break even point in TB for each access tier.

Expand table

Calculation	Hot	Cool	Archive
Monthly price per GB of Data storage (pay-as-you-go)	$0.0208	$0.0115	$0.002
Monthly price per GB of Data storage (pay-as-you-go)	$0.0208	$0.0115	$0.002
Price for 100 TB of reserved storage	$1,747	$966	$183
Break even for 1-year reserved capacity	82 TB1	82 TB	89 TB
Break even for 3-year reserved capacity	66 TB1	74 TB	82 TB

1The hot tier has multiple pay-as-you-go rates. The price of the first 50 TB and the price of the second 50 TB are factored into this calculation.

Hi @Niharika Siddana

Welcome to Microsoft Q&A, thanks for posting your query.

Adding additional information for the above response.
The billing of 2000 INR credits daily for using Azure Blob Storage could be attributed to various factors, including data storage, operations, data transfer, and other features that may incur charges. Azure Blob Storage has a detailed billing model where costs are associated with different meters, such as data storage (charged per GB per month), operations (charged per transaction), and data transfer (charged per GB).

To understand the specific reasons for your daily charges, you may want to review your usage metrics and the types of operations being performed on your Blob Storage resources. Additionally, consider checking if there are any unexpected operations or features that might be contributing to the costs.

Meter	Unit
Data storage	Per GB / per month
Data storage	Per GB / per month
Index	Per GB / per month1
Operations	Per transaction
Data transfer	Per GB2
Data retrieval	Per GB3
Blob index tags	Per tag4
Change feed	Per logged change4
SSH File Transfer Protocol (SFTP)	Per hour4
Blob inventory	Per million objects scanned4
Encryption scopes	Per month4
Query acceleration	Per GB scanned & Per GB returned
Point-in-time restore Data Processed	Per MB restored

1 Applies only to accounts that have a hierarchical namespace.
2 Applies only when copying data to another region.
3 Applies only to the cool, cold, and archive tiers.
4 Applies only if you enable the feature.
