This calculator will show you how much you might earn over the lifetime of investing with regular contributions at a given rate of interest/return.
It shows you the interest/rate of return earned beyond your regular contributions you can earn over a given period of time, based on your selected initial investment plus a fixed monthly addition.
The calculator compounds monthly and assumes deposits are made at the beginning of each month.
