As a follow-on to this question, if you wanted to have a $2.5 million nest egg in 20 years, what would the nest egg value have to be today (assuming no future contributions)?



Assume:




  • 20 years until first withdrawal

  • 4.0% annual inflation

  • 8.0% annual return

  • $2.5 million future balance

The formula for future value with no contribution is just FV = PV(1+r)^n, so reversing that to find present value, you get PV = FV / (1+r)^n.



So in your case:



     2,500,000 
PV = --------- = 536,360
(1.08)^20


Note that inflation is irrelevant in your question since you didn't ask about the equivalent of 2.5 million in today's dollars. But if you wanted that, you'd just subtract the rate of inflation from r and make the same calculation.

  • When you adjust for inflation, the number I compute is 536,360*(1.04)^20 or 1,175,230.

  • Just as I was about to comment that 4% felt high, I looked at inflation for 50 years 1967-2017, and sure enough, 4.1% CAGR. Spoiled by the recent low rates, last 20 years or so.
