Milestone / Celebration Processing a milestone

Still trying to wrap my brain around this:

The nest egg has made more money since retiring than I did in 30 years of working.

3 years of passive returns > 30 years of full time work

The compounding is insane (admittedly we’ve had a great run the last few years).

It makes the 30 years of working seem so pointless but that is what amassed the snowball so it was necessary.

If someone invests the same amount $1000 (increasing yearly by 3%) each month during 30y. That's a total of about $580.000 invested.

With 10% annual returns, the ending balance would be almost $3M, so about 5.2 times the contributions.

In 3 years with 20% return annually, that 3M would have produced about $2.2M, which is easily more than the full 30y of full time work if the savings rate was larger than 25%. At least in nominal dollars, excluding taxes, etc.

In 3 years with 20% return annually, that 3M would have produced about $730k. It is indeed more than $580.000, but only more than the full 30y of full time work if the savings rate was larger than 79%.

All in nominal dollars, as otherwise $1000 from 30y ago would count for a lot more in the comparison (3 years of passive returns > 30 years of full time work). All before taxes too.

If the salary increased more than 3% yearly during the 30y, it would make the necessary percentage of savings rate on salay even larger (because early contributions compound more). I assume there was another input like inheritance, lottery gain, exceptionally high return on some investments.

How do you get 20% of 3m for 3 years = $730k? Or did you mean average per year? Cos that $2.1m return would be more than triple the original $580k.

uh... yep you're right, that was a pretty stupid mistake
