Fact is, nobody can tell you that number, it’s up to you.
A recent Charles Schwab study found that the average American felt they need about $1.7 million to retire comfortably. Where do they get that? Probably from reading what out-of-touch experts write.
If you have $1,700,000 in investments for retirement, they will generate about $68,000 in income using the 4% withdrawal rule (and if you are smart, most of it could be tax free).
Now add the average Social Security benefit for a couple;$25,200 (at least 15% tax free) and the household income is $93,200. That is 50% more than the median household income in the US.
So, how much do need to retire with financial security? Here is more realistic information.
