How it works
The annual rate is divided by the number of compounding periods, the starting balance grows by that factor each period, and each deposit compounds for the periods remaining after it.
Example
$10,000 plus $250 per month at 5% for ten years grows to about $55,291, of which $15,291 is interest on $40,000 of deposits.
