>>Nobody can retire on that. It takes a minimum of 25% of gross income invested at 6% to successfully retire in 40 years.<<
Depends on your “magic number” — I am ready for retirement at a MUCH lower level than that and only really started 25 years ago.
There are bazillion calculators out there — it would be prudent for ANYONE (especially people early i their careers) to model and save thoughtfully.
If I would have started in my 20s instead of my 30s I would be retired now (before 60).
I am retiring at 62 but taking SS at 64 (or maybe 68/70 depending on how much fun I want to have).
We all have our own risk tolerance regarding how much coverage we want for our nest egg. Far as I’m concerned the 4pct rule is bunk and more like 2.5pct plus at least 100pct contingency. One can’t afford to be wrong on this.
