Worth knowing
Making compounding work for you.
The rule of 72: about 10.0 years
Divide 72 by the rate to estimate how long money takes to double. At an APY of 7.23% the exact figure is 9.9 years.
Time does the heavy lifting
The longer you leave money alone, the bigger the share of the balance that is interest rather than your own deposits. Starting a few years earlier often matters more than saving a little more each month.
