all back of napkin but im guessing you're playing with 55k after taxes, so 4.6 k a month.
so your total costs (rent/mortgage, food, kids, all in) is only 1.6 k? and you're saving ~65% of what you take home? you must live extremely frugally, this is not normal. so kudos, but don't try to make it sound like everyone should do what you're doing. most people do just fine saving 20-30%, even less.
