Do I look like some kind of math magician to you? Besides how can we solve a math problem with letters? Letters are for words!

Just put numbers there and solve it, is that really that hard? You could solve this thousand times while you wait for answers geesh

Why don't you pay attention in your 6th grade math class? Ask your teacher? Please answer this question: What in the F_CK does this have to do with blackhat SEO?

What is happening to my BHW??? Knuckleheads everywhere with nothing to do but jump on the forum and in their first post(s) give the impression that they're the next serial killer and if you don't either agree with them or come up with a solution to a problem, you're the dick. Hey OP, how about you join a MATH forum?

OP, play around with excel, its designed to do that. What you are looking to calculate is Future Value (FV for short). The usual formula is FV=(rate;nper;pmt;PV) nper = number of years (or any period you get interest on), pmt = the payment you pay into an account (can also be negative, so us this), PV = present value (the money you have for investment). I'm not sure, but I think you can just take the 5% off of 10% interest, so you would just have 9,5% interest a year. So if we run FV=(9,5%;5;0;100) we get a FV of 157,42$ after 5 years. 10 years is 247,82$. There is lots of info on this calculations and basic finance on the internet.
