### Example: Data Store Cost Calculation

### Active Data Store Cost Calculation
36
+
37
+
You can use the following tools to get **an accurate estimate** of your active data store costs:
38
+
39
+
- Use the [pricing calculator](https://www.dragonflydb.io/pricing#calculator) to estimate the cost of a data store
40
+
based on its memory size, cloud provider, and region.
41
+
- In [Dragonfly Cloud](https://dragonflydb.cloud/), the data store cost (excluding data transfer cost and backup
42
+
storage cost) is displayed every time you create or update a data store.

### Active Data Store Cost Example

45
36
46
To illustrate with an example, let's consider a Dragonfly Cloud data store that is:
37
47
38
-
- Configured with **12.5GB** of provisioned memory on the **enhanced performance tier**.
48
+
- Configured with **12.5 GB** of provisioned memory on the **Enhanced** compute tier.
39
49
- Configured with **2 zones**, one primary and one replica.
40
50
- Located in the **AWS us-east-1** region.
41
51
- Active for **2 days, 1 hour, and 10 minutes**.
42
52
43
53
The cost of this data store can be calculated as follows:
44
54
45
-
- Cost for 1GB of enhanced performance tier data store in AWS us-east-1: around $11.0 per month.
46
-
- Total hours used: 2 days x 24 hours per day + 1 hour + 10 minutes (rounded up to 1 hour) = 50 hours.
47
-
- Total hours in a month: 365 days / 12 months x 24 hours per day = 730 hours per month.
48
-
- Total cost: **$11 x 12.5GB x 2 zones x 50 hours / 730 hours per month = $18.84**
55
+
- Cost for 1 GB of the **Enhanced** compute tier data store in the AWS us-east-1 region = **$11.0 per month**.
56
+
- Total hours used: 2 days x 24 hours per day + 1 hour + 10 minutes (rounded up to 1 hour) = **50 hours**.
57
+
- Total hours in a month: 365 days / 12 months x 24 hours per day = **730 hours per month**.
58
+
- Total cost: **$11 x 12.5 GB x 2 zones x 50 hours / 730 hours per month = $18.84**

## Data Transfer
51
61
52
62
- Data transfer fees are costs imposed by cloud providers for moving data across various destinations,
53
-
including between clouds, the public internet, different cloud regions, and even between availability zones within the same region.

within the same region.

65
- Dragonfly Cloud applies public data transfer fee rates set by cloud vendors for data store traffic.

For detailed and specific pricing, please refer to the [AWS](https://aws.amazon.com/ec2/pricing/on-demand/) and [GCP](https://cloud.google.com/vpc/network-pricing) pages.
56
-
-**To reduce data transfer expenses, using [data stores with private endpoints](./datastores.md#private-endpoint) is recommended**.
57
-
- Additionally, data stores with high-availability configured may incur charges for cross-availability zone traffic within the cloud provider's network.

[^2]: The compute performance tier determines the CPU-to-memory ratio for the data store. Currently, Dragonfly Cloud
80
+
offers **Standard**, **Enhanced**, and **Extreme** performance tiers.
