Why do people even calculate or care the gross margin percentage outside of manufacturing and retailing?

I genuinely fail to see why and how it's a number with any meaning. For example, a plumber fixed your house's pipe. He charged mostly for his time instead of the tools and materials he used (righteously). If you count his 'gross margin percentage' it might be higher than Apple. Does it mean anything?

It doesn't mean anything because you're comparing the plumber with Apple, but if you compare plumbers to each other, or possibly even a plumber to an electrician, it could be useful.
