It's a few years out of date now, pulling from 2016 data, but one site I've used in the past is this:
https://personalfinancedata.com/networth-percentile-calculator/
It has fields where you can put in your age range, your net worth, and it will give you an estimate of your ranking. According to it, a net worth of $100K would get you into roughly the top 50%, using the default age range of 18-100. A net worth of $1M would get you into around the top 12%.
I was thinking that $507K for the top 50% seemed awfully high, considering how many people have nothing saved, or are in debt. You can have a high paying job, a nice house, and a nice car, but if you have no savings, are paying off college loans, and upside down on the mortgage and car, you might look successful, where people would presume you're in the upper echelons, but the reality is, you're broke, son!
I could buy that $507K number as being a mean, or even median, for the top 50% rather than the point-of-entry. But, then the other numbers for the top 10%, 5%, etc seem low, like they'd be the point-of-entry, rather than a mean/median.
Regardless of the number disparities though, it definitely drives home the point that a dollar doesn't go as far as it used to. I can remember when I hit the $1M mark, back in 2015. At that point, the site I referenced above was pulling from 2012 data, I think, so it was still off. But, at the time, it put me in roughly the top 10%. My first thought was that this, THIS, is the top 10%? It's really not so hot, and maybe this country really is worse off than we've thought.
It also started making me think about how the rich are often demonized, and the cries to make them pay "their fair share" of taxes. Umm...wakeup call...there aren't enough rich people to go around, to pay for all of that!
Of course, there are also big disparities in cost across the country. Where I live, in the DC area, $1M is no great shakes. But out in some of the more rural areas of the midwest, it would probably let me live like a king.
