This is maybe a bad example because it is exactly how people talk about compensation. I’ve never heard anybody say “oh I made $70k last year after taxes and rent.”
But net salary is what people often mention or look at when considering offers.
So, my net salary / take home pay is $X is what is normally talked about between people etc.
Really? That's pretty much how I and everyone I know talks about compensation.
Maybe this is a regional thing?
