Question: how much money do you need to just live off the interest?
Answer: If you're saving at a rate of $10,000 per year and expect to increase this amount by 2% per year, you can expect to have $676,145 by the time you're 65. If you're willing to use some of your principal as well, the calculator estimates that you'll be able to withdraw an annual income of $34,496 per year for 30 years.
