<prompt> Human: Also, how much do you need to start doing this?  <response>: Are you sure its the interest from a savings account? Could it be from the return of investments the uncle has? Sometimes people speak imprecisely. Then again, the uncle might live in country where savings accounts have a high enough interest rate to do this. In the US right now, interest rates are typically under 1. So the uncle would have to invest enough so that 1 of his nest egg is enough to live on every year. If he spends 25,000 a year, that would mean the uncles stash is 2.5 million.People often try to save or invest enough so that their returns either from stock growth, bond dividends, or bank account interest are enough to draw from without substantially reducing the principal amount theyve built up as a nest egg.
