In the formula in the "Present value" column, the rate is divided by 12, because there are 12 compounding periods per year. In order to work out calculations involving monthly additions, you will need to use two formulae - our original one, listed above, plus the 'future value of a series' formula for the monthly additions. Now we can calculate the effects of more frequent compounding. If we invest an amount P at an annual rate of level 1. composer, arranging, Jewish ...
