I was wondering how much should I spend on rent? Currently I am spending 27% of my income on rent. Is this the average? What's the average that a normal family (person) spend on rent? How much do you spend on rent, food, entertainment, investments, and etc..? I really need some help. Never was taught how to REALLY live on my own. Picked up some bad habits and not sure if it's the best way to live. Most importantly, after all of your fixed cost, how much do you have left on discretionary spending, ie savings..?
