Frequently asked questions

How powerful is compound interest?

One worked example used by existing calculators: $10,000 plus $500 a month at 7% a year becomes about $691,150 in 30 years — most of it interest, not deposits.

What is the rule of 72?

Divide 72 by your yearly return to estimate how many years it takes money to double — at 7%, roughly every 10 years.
