As a single person yet so many past debt from family side and the expenses to live for me however 50K a year is good enough for me to live comfortable. I feel anything more than that is a bonus. 5 years of 50K can even wipe out the financial crunch too.I guess a lot of times we can think of comfortable money changes with the amount of money we owed. Once everything is cleared, I suppose money less than 50k would make comfortable to not worry.
