I had a look on google but couldnt really find anything of much help so I thought I would give the forum a try.
Compound interest can be worked out with the formula A=P(1+R)^N A being the amount including interest, P being the initial amount, R being the rate of depreciation or appreciation, and finally N being the number of year for which this happens.
however how does the formula change if you added an extra sum of money in every year?
Any help would be greatly appreciated. Thanks Alan
