How to delegate Resource costs overview on Azure Resource Groups?

We are currently moving our on-premise applications to Azure. Our department received a Resource Group in our companies tenant. We are able to create new resources within the RG, however we are not able to see the associated costs after we created the resource.

Desired result: overview of current resource costs and rate of spending for our department

Currently only the head of internal IT is able to view the spending per department.

Is it possible for the global administrator to delegate the rights for viewing Resource Group costs to a department?

Solution

There is a new role added to Azure, Azure Billing Reader role.

The new Billing Reader role allows you to delegate access to just billing information with no access to services such as VMs and storage accounts. More info.
