[Request] If, after we cure all aging-related diseases and become clinically immortal, I continued to save $1000/month towards a mutual growth investment fund that compounds, indefinitely, from age 40, when will I hit $1m? $10m? $100m? $1b? $10b? $100b? $1t?

This will be a crosspost between:

• and r/Futurology: https://www.reddit.com/r/Futurology/s/oVsMQtBP03

How long will it take and how old will I be when I hit these milestones, and when we're no longer mortal thanks to those world-changing medical advances?

Depends on the interest rate and compounding period.

At 8% return compounding monthly it would take (to the nearest year):

26 years to reach $1m 53 years to reach $10m 82 years to reach $100m 111 years to reach $1b 140 years to reach $10b 169 years to reach $100b 197 years to reach $1T.

So roughly a power of ten every 30 years.

As a beside, by not saving that extra thousand a month, your 197 year return would only be worth around $6.6 billion.

Another user on this thread compounded 8% interest. They got to becoming a trillionaire in only 197 years. Did you compound 6% interest? I get the impression that you may have forgotten to compound.

Notice that everyone else in this immortal world can become a billionaire too, just by waiting a hundred years. This should give you some idea of what inflation will be like in a hundred years. If everyone is a billionaire, no one is a billionaire.
