Well, that's pessimistic of you, but yeah, there's no way to make your numbers work. I guess you'll need to get a job.

How much, in today's dollars, do you want to spend per year?

So, if it were just you, you would need to start with $.

How old will you be when you start having kids? The longer you wait, the easier it is to save up for their needs.

How many kids will you have, total, during your life?

Just to be on the safe side, we'll presume you have all of your kids, all at once.

So, starting from the day you are born, you will need to save enough money so that when you start having kids, they will each have the same starting money you did. Then the whole cycle perpetuates forever.

So, you must save $ in years.

At your growth rate, that will cost about $ per year.

That brings your total amount you need to receive per year to $.

So the final total is this:

$

That's how much you need to have started with on the day you were born, and that's how much you will give to each of your children on the days they are born. You will die with more than that.

Because, once you give your kids their money, you will have more money than you need and so it will grow faster than you spend it. You can give it all to charity in your will. That's right, your bank account will never go below that number.

In fact, if you live to be a hundred years old, the final amount you will be able to give to charity is:

$*

* - and that's in constant dollars.

But if you'd rather die with as little money as possible, at the ripe old age of $100, you just need to start with:
