# Cost estimate: Retrieve data from archive storage for analysis
14+
15+
This sample estimates the cost to retrieve a portion of data from the archive tier before the 180 day limit.
16+
17+
> [!IMPORTANT]
18+
> This estimate is based on [these sample prices](blob-storage-estimate-costs.md#sample-prices). Sample prices shouldn't be used to calculate your production costs. To find official prices, see [Find the unit price for each meter](../common/storage-plan-manage-costs.md#find-the-unit-price-for-each-meter).
19+
20+
## Scenario
21+
22+
Your company stores 20 TB of data in the archive tier for long term retention. However, after only three months in archive storage, 20% of that data must be retrieved for analysis. You've been asked to estimate what it will cost to get that data from archive storage and then download that data to clients for analysis.
23+
24+
The storage account is located in the West US region, is configured for locally-redundant storage (LRS), and does not have hierarchical namespaces.
25+
26+
## Costs
27+
28+
The following table describes each cost.
29+
30+
| Cost | Description |
31+
|----|----|
32+
| **Change tier to hot** | First, blobs must be moved out of archive storage for analysis. To do this, administrators will change the tier of each blob from `archive` to `hot`. All tools and SDKs use the [Set Blob Tier](/rest/api/storageservices/set-blob-tier) operation to accomplish this task. That operation is billed as a read operation on the archive tier. |
33+
| **Data retrieval fee** | This meter applies to each GB moved from the archive tier and into an online tier such as the hot tier. |
34+
| **Early deletion fee** | If data is moved out of the archive tier before 180 days have transpired, a prorated early deletion fee is applied to the bill. |
35+
| **Read from the hot tier** | Once data is moved into the hot tier, clients will need to download that data. Each download is billed as a read operation. |
36+
37+
## Estimate
38+
39+
Based on [these sample prices](blob-storage-estimate-costs.md#sample-prices), the following table shows how each cost component is calculated. This sample estimate doesn't include the [cost of data storage](blob-storage-estimate-costs.md#the-cost-to-store-data) which is billed per GB.
40+
41+
| Cost | Cost factor | Calculation | Value |
42+
|------------------------|---------------------------------------------|---------------------------------------|-------------|
43+
| **Change tier to hot** | Number of Set Blob Tier operations | 2000 blobs * 20% | 400 |
44+
| | Price of an archive read operation | | $0.00055 |
45+
| | **Cost to change tier to hot**<br></br> | 400 operations * $0.00055 | **$0.22** |
46+
| **Data retrieval fee** | Total file size | | 20,000 GB |
47+
| | Data retrieval size | 20,000 GB * 20% | 4,000 |
48+
| | Price of data retrieval (per GB) | | $0.0220 |
49+
| | **Cost to retrieve**<br></br> | 4,000 blobs * $0.0220 | **$88.00** |
50+
| **Early deletion fee** | Rough number of months penalty | (180 days - 90 days) / 30 days | 3 |
51+
| | Price per month of archive storage (per GB) | | $0.0020 |
52+
| | **Cost of early deletion**<br></br> | (4000 blobs * $0.0020) * 3 | **$24.00** |
53+
| **Read from hot tier** | Number of read operations on hot tier | The number of blobs moved to hot tier | 400 |
54+
| | Price of a read operation on the hot tier | | $0.00000044 |
55+
| | **Cost to read from hot tier**<br></br> | 400 operations * $0.00000044 | **$0.0002** |
56+
| **Total cost** | | $0.22 + $88 + $24 + $0.0002 | **$112.22** |
