This assumes the rate never changes and nothing is withdrawn. Real returns bounce around, so treat the ending number as a middle-of-the-road estimate rather than a promise.
Compound Interest explained simply
This is the one we get most excited about at Rauner's. Money can make more money. Then that new money makes money too. This shows how a snowball of savings grows when you leave it alone.
For example
Put in $10,000 at 7% and don't touch it for 30 years. It grows to about $76,000, and you never added another dollar.
