What are some good benchmarks for networth based on YOE of 2, 5, 10, and 20?
The S&P 500 returns about 7% after inflation. So you can work out how much you should have saved my year n, as
100k x (1.07^n - 1)/.07
That gives these values:
2yr: 0.207 million
5yr: 1.8 million
10yr: 13.8 million
20yr: 41 million
If you think you should be saving a lesser amount per year you can use a different multiplier in the above future value of an annuity formula.
In reality most people retire rather than continue working before they get to the big number at 20yr because there is more to life than having a big investment. So I guess most people retire or do something different after 3mil or so.
