Determining memory overhead for guest VMs

I'm trying to determine what the "proper" amount of memory for my VMs is.. Right now, I'm running a single instance of Windows 10 @ 10GB, but the Vbox process is taking 14GB of RAM.. that seems like a lot of overhead.. I've been searching for any documentation or details on this, but I have yet to find anything that indicates any kind of formula for the overhead.

This is on a CentOS 7 host..

Thank you for any guidance..

How did you determine that?
Any chance that you're using heavy file I/O between the host and the guest? And the file cache might be taking its toll?
