Interesting that the template does not insert the final "br". Dunno why, but not gonna question it.

Template:Cost does give output that is consistent, and consistent with the game. Cost accepts variants of some of its parameters becuase we cannot force consistency during input. Almost everyone who uses Cost on a regular basis uses Source Mode for input. TemplateData in the new VisualEditor solves this problem, but we have craptons of work to do before our Wiki is ready for the new VE--namely, creating TemplateData for all the templates on the Wki. (VE chokes if TD is missing.)

I don't understand what you by "multiplying" something, in reference to Cost or Cost4Templates. Please clarify.
