The calculator bases the class on income, so it doesn't need to assume anything about spending.
That's why you can't tell by just looking at people's situations if they are middle class or otherwise. Some folks borrow to the hilt and live well, but spend every dime on making payments (with interest.) They appear to be middle class, but their income would say otherwise. My BFF comes to mind. 78 and in debt half a Mil. But seems solidly middle class or higher. And, I guess his income would support that. 2 SS and a megacrop pension adds up. But, what a way to live, deciding what bills can wait and what absolutely has to be paid this month. I couldn't live like that.
Others (probably like me - especially when I was w*rking.) drive older cars, live in older houses, buy fewer "designer" clothes, take fewer exotic trips (though I did visit Hawaii 12 time while I was w*rking), etc. People observing me would say "lower middle class" I'm guessing, but in any case, I never projected wealth - nor do I now. Just not my style nor is it "me." YMMV
