I think you’re overestimating your groceries and utilities. What city do you live in? $2400/mo would get you a decent sized house in many US markets (aside from the big three or four cities).

You make plenty to move out. Living at home too long isn’t good for your self esteem and it doesn’t prepare you for real life. Life gets way too comfortable when you stay at home.

Moving out will be the best thing you’ll ever do.
