Frequently asked questions
How does the calculator find the nest egg I need?
It calculates how much money produces the income you want with real returns alone, without spending the principal. That way the income lasts your whole life and keeps up with inflation.
What is the real rate of return?
It is the return above inflation. If an investment earns 10% a year and inflation is 4%, the real gain is close to 5.8%. Using the real rate keeps every value in today's money.
What about Social Security?
If you will receive a pension or Social Security, enter only the income you need on top of it. The calculator only covers what you will need to invest on your own.
