# Enable Split Cost Allocation for EKS
To view pod-level EKS costs in OneLens, you need to enable split cost allocation from two places in your AWS account:
1. **CUR Preferences** – to include split cost allocation data in the Cost and Usage Report (CUR).
{% hint style="success" %}
The **Split Cost Allocation Data option in CUR preferences** is already enabled for you during onboarding through CloudFormation Templates (CFTs).
{% endhint %}
2. **Cost Management Preferences** – to opt in to EKS cost allocation.
{% hint style="danger" %}
### Warning: Require Payer and Regular Account Access
Split cost allocation must be configured from a **Payer and Regular account** in AWS Cost Management Preferences. If you do not have access to the payer account or if it is managed by an external third-party provider, **please raise a ticket** with **Payer Account Owner or the provider** to enable split cost allocation.
When using an unsupported account, you'll see the following message:

### **Enable EKS Split Cost Allocation**
1. Open the [**AWS Cost Management Console**](https://us-east-1.console.aws.amazon.com/costmanagement/home#/home).
2. In the left menu, select **Cost Management Preferences**.
3. Under **Split cost allocation data**:
1. Select **Amazon Elastic Kubernetes Service**
2. Choose **Resource Requests**
4. Click **Save Preferences** at the bottom right.
{% endstep %}
{% step %}
### Ensure Required Tags Are Enabled
After enabling split cost allocation, AWS automatically creates and activates the following cost allocation tags **in your payer account**:
* `aws_eks_cluster_name`
* `aws_eks_namespace`
* `aws_eks_node`
* `aws_eks_workload_type`
* `aws_eks_workload_name`
* `aws_eks_deployment`
These tags must remain enabled for OneLens to attribute pod-level costs accurately.
{% hint style="warning" %}
## **Note**
If any of the AWS-generated EKS tags were previously disabled in your account, enabling split cost allocation will **not** automatically reactivate them. You must manually enable those tags from the [**Cost Allocation Tags**](https://us-east-1.console.aws.amazon.com/costmanagement/home#/tags) page in the Billing Console.
{% endhint %}
**To verify:**
1. Go to [**Cost Allocation Tags**](https://us-east-1.console.aws.amazon.com/costmanagement/home#/tags) in the AWS Billing Console.
2. Open the **AWS-Generated Tags** tab.
3. Filter by **`eks`.**
4. Ensure all required tags are enabled and active.
{% endstep %}
{% endstepper %}
After the setup, your CUR will start including pod-level cost breakdowns. OneLens will use this data to provide deeper visibility into your EKS costs.
## Additional Cost for Split Allocation in EKS
There is **no direct AWS fee** for enabling this feature. However, you may incur an estimated **$2.73/month per 10,000 pods** due to increased CUR data size and processing overhead.
