I actually retired at age 40 with less than 700k. My wife and I own a house. We both moved back to Canada, so we don't worry about health care costs. And, we really don't spend money on much. I figured our food/living costs comes out to $1000 a month. We don't have kids or any other big expenses. We're pretty frugal too. Anyways, it all depends. Some will tell you 7 million. That's fucking absurd. If that was true, hardly ANYONE in the US would be able to retire. Others will probably tell you 5 million, which I still find absurd. Anyways, regardless of what people on here will say, you already sound like someone who is indecisive. I've noticed that people who are always searching for their answers from others will never be satisfied by them.
