Question: how much money do you need to live comfortably after retirement?
Answer: To figure out how much income you'll need in retirement, take your estimated monthly expenses (be sure it's realistic) and divide by 4%. So, for example, if you estimate you'll need $50,000 a year to live comfortably, you'll need $1.25 million ($50,000 ÷ 0.04) going into retirement.
