Yeah, my numbers were intentionally a bit inflated. I was more or less making the point that when you sit down and really add up everything you pay for, it can be shocking. But when you're thinking of moving out, you have to account for all those "other" costs. Too often, when asked "what are your bills", people only think of rent and loans. They don't think about gas, or car insurance, or food, or whatever.

In your case, if we just assume utilities stay at $200, and you spend the same on food/eating out, you have about $3506.67 in bills with the rent. So right now, you're at $600 extra per month. But that also doesn't have your cell phone in it. Or any car repairs, or potential car payments. Or saving any money, outside of your existing retirement contributions. Or saving money for travelling. So it feels like it'll be a bit tight w/o a roommate.
