I'm looking at some business that sell between a 3-5 multiple, However, I want to be more accurate when giving these businesses a multiple. So, instead of just making a educated guess and saying that a particular business has a 3.5 x multiple, how do I come up with a better way to give these businesses a more accurate multiple. Say for example, maybe I use a scorecard.

Does anyone have experience doing this? Does anyone have a template that I could use?
