    I will surely give it a try soon : remember : |dw:1341657452319:dw|P = principal amount (the initial amount you borrow or deposit) r = annual rate of interest (as a decimal) t = number of years the amount is deposited or borrowed for. A = amount of money accumulated after n years, including interest. n = number of times the interest is compounded per year

    |dw:1342093514034:dw| There is a formula to calculate the monthly investment and return at a future period with Interest Monthly Amount A= $50 Years n = 10 * (12 months) = 120 Rate yearly= 15% --- Monthly rate (r ) = 15/12= 1.25% = 1.25/100= 0.0125 Formula = A*(1+r) * (1+r)n -1 r Substituting it: = 50*(1+0.0125) * (1+0.0125)120 -1 0.0125 = $ 13,932.86 For getting $25000, in the same formula ‘’n’’ would be not there .. so it would get complicated. You might need Log or trial n error method to solve. I simply use EXCEL sheet n try replacing the N and the answer I found is 159 months approx. i.e. 13.25 years approximately Hope I helped and you understood. 
