How to see the file transfer speed on a mac

Hi, I'm kind of a beginner with a Mac, I have worked on windows for all this years and now I have a small dilema. Can someone please tell me how you can see the file transferring speed on a mac. When you copy and paste from one drive to another, or from time capsule to my mac, etc a dialog appears showing you a progress bar and the time remaining. I would also like to see the speed of the transfer. Is it posible to see this variable?
