Question: how much money do you need to retire on comfortably?
Answer: How much money do you need to retire comfortably? According to AARP, one common rule of thumb is that you'll need 70% to 80% of your pre-retirement income after you retire. So if you made an average of $75,000 per year during your working years, you may only need $52,500 to $60,000 in retirement.
