## What's new

### [<mark style="color:blue;">**Revamped Cost & Usage in the DCD**</mark>](/cloud/set-up-ionos-cloud/management/usage/cost-and-usage.md)

{% hint style="success" %}
**March 25** The **Cost & Usage** view has been revamped with a fresh and intuitive design. It provides:

* A comprehensive summary of your account's cost for the past six months, including the current month.
* A monthly report with detailed insights into all costs associated with using Virtual Data Centers (VDCs) and consuming other products and services.
* Transparency about usage patterns and costs across product categories by displaying the total units consumed, cost per unit, and total cost incurred.

```
GET https://docs.ionos.com/cloud/release-notes/previous-releases/2025/march-2025.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
