There is, but there's less if you're using managed services where possible and it's visible in a way which wasn't true for many large organizations. I can go into any cloud provider's console and see a detailed breakdown of what I'm paying and why, and how much of it is over/under-utilized, but getting that same report from an enterprise IT department is usually a project.

If a cloud machine is idle is you can shut it down and stop paying for it.
