* MaxSavings - maximum cost savings, the best for non-production environments
* Balanced (default) - optimally balances cost and resiliency
* ExtraHeadroom - the best fit for latency-sensitive environments&#x20;
* MaxHeadroom - keeps the environment above the highest spikes

{% hint style="info" %}
The **Optimization Policy** can be set for the entire [cluster](https://docs.perfectscale.io/2.0-self-hosted-or-perfectscale-documentation/administration/cluster-settings#general-settings) and a specific [workload](https://docs.perfectscale.io/2.0-self-hosted-or-perfectscale-documentation/podfit-or-vertical-pod-right-sizing#workload-optimization-policy). The workload's **Optimization Policy** takes precedence and will override the value defined at the cluster level.
{% endhint %}

{% hint style="info" %}
If a policy is set through the exporter when installing the PerfectScale Agent, it cannot be modified in the UI afterward. You can still change the policy by upgrading the exporter with the new value, or you can return it to the default by upgrading the exporter without specifying any value (this will also enable the option to change the custom time window through the UI).

#### Table summary

<figure><img src="https://content.gitbook.com/content/zCh9aABpk7yLeToPr6vk/blobs/zYLA0QY9tPoOBsrBiiT8/image.png" alt=""><figcaption><p>Summary</p></figcaption></figure>

This section summarizes the total cost of clusters and the achievable cluster costs through PerfectScale’s recommendations and provides insights into reducible pod waste and idle node costs. These metrics highlight potential savings and opportunities to minimize waste, helping to guide data-driven decisions for more efficient resource allocation.

## Projected vs Actual values <a href="#projected-vs-actual-values" id="projected-vs-actual-values"></a>

The Overview screen displays data using the default 30-day timeframe. If a cluster has been running for less than 30 days, PerfectScale will calculate and display the **projected values for Cost, Potential Savings, Pod Waste, Node Idle, and CO₂** based on the data collected so far.

**Example**: If a cluster ran for 14 days and cost $100, the projected 30-day cost would be $214.

When projected data is shown instead of actuals, a relevant tooltip will be displayed:

<figure><img src="https://3591580169-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FzCh9aABpk7yLeToPr6vk%2Fuploads%2FNBNClUg0sUzuAS1P8PBw%2Fimage.png?alt=media&#x26;token=eb363312-989f-434d-97e0-22e97fbc7a10" alt=""><figcaption><p>Projected values tooltip</p></figcaption></figure>

### Excluding clusters from projections <a href="#excluding-clusters-from-projections" id="excluding-clusters-from-projections"></a>

In some situations, you may want to exclude some clusters from the projection logic. This is especially useful for ephemeral clusters that run for less than 30 days/month, where a 30-day projection may not be accurate.&#x20;

For these cases, you can seamlessly exclude such clusters from the projection logic, allowing PerfectScale to display the actual data for the period during which the cluster was running.&#x20;

To exclude a cluster from projections, add the following cluster label. Learn more about cluster labels [here](https://docs.perfectscale.io/2.0-self-hosted-or-perfectscale-documentation/administration/cluster-settings#cluster-labels).

```yaml
exclude-from-projections: true
```

When a cluster is excluded from projections, a relevant tooltip will be displayed:

<figure><img src="https://3591580169-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FzCh9aABpk7yLeToPr6vk%2Fuploads%2FZ1v1QAKmmwlbhNpgv1ok%2Fimage.png?alt=media&#x26;token=dee64fef-fe5b-4d39-8578-aede1081ed72" alt=""><figcaption><p>Cluster excluded from projections</p></figcaption></figure>

[^1]: If the cluster has only partial data in the selected timeframe, PerfectScale will display the maximum available data. (i.e., if the cluster was onboarded a week ago, we will show one week's data even in a 1-month selection).
