How long do you think it can last?

i think i could make it last my lifespan at least,easily. i'd invest a good portion of it also.

Well, as long as it's invested and spent wisely, with only blowing, say, a million dollars on random things, :) then it could last at least for the rest of my lifetime. And if properly managed, it could become a lifetime inheritance for my son, and his children and so on and so forth. That's a monstrous amount of money, so i don't know why it wouldn't last forever!!

Hello Titaniumsoul, I haven't run the numbers through standard amortization, to take into account compounding interest. But, roughly this amount in non-aggressive growth investment, at a base 5% interest would earn 20k the first year. Add monthly compounding to that, or if it were invested at a higher rate, the principle would grow more quickly. I would personally not want to live on 20k - 25k per year. Especially, when considering inflation. So, I would have to continue to work, or deplete the principle. I would rather work than deplete the principle. But here's a rough breakdown. Of course, this is figured at 5% annual interest, not accrued monthly. So, the real income generated would be slightly higher. 1st year - 400,000 plus 20k interest @ 5% 2nd year - 420,000 plus 21k interest @ 5% etc... If it were just me, and I chose not to work (which I wouldn't do) and lived off the principle instead, the sum would be gone in less than 10 years, at my current standard of living. Of course, the number of variables are immense. If I took the 20k (approx) of interest, and supplemented my other living costs with the principle ... or if I let the interest accrue for 20 years, without touching either the interest or the principle, then if my mental calculations are correct, I'd have around a million dollars. I'm tired, so if my math if off, please forgive me. But, having a million to live off of for retirement would be a whole lot more comfortable than 400,000 at age 43. So, I guess I better keep plugging away at work, eh?
