How the math works
- The yearly return is turned into the equivalent monthly rate, so a year without deposits grows by exactly the rate you enter.
- Each month the balance grows by that rate, and then the monthly deposit is added.
- The same return is used every year. Real investments rise and fall from year to year, can lose money, and have fees and taxes that this calculator leaves out.
