What compounding means
Each month, interest is added to your balance, and next month you earn interest on that larger amount too. The effect is small at first and grows with time, which is why starting early matters more than the size of the deposits.
The calculator adds your deposit at the end of every month and applies one twelfth of the yearly return to the balance each month. It ignores taxes and inflation.
