Mr A deposited $700 at the end of each month of calendar year 2010 in an investment account of 9% annual interest rate. Calculate the future value of the annuity on Dec 31, 2011. Compounding is done on monthly basis.

FV=P{[1 + R]^N - 1/ R

FV=700{[1 + 0.09/12]^(2*12) - 1] / (0.09/12)}

FV=700{[1.0075]^24 - 1] / (0.0075)}

FV=700 x {26.188471.......}

**FV=$18,331.93 Note: This balance is on the assumption that 9% is compounded monthly.**

NOTE (to the first Answer)

Mr A deposited 700$ only through the one year (2010),__ not__ through 2 years.

That means: in the year 2010 - 12deposits of 700$ each; in the year 2011 - 0 new deposits.

Through all the year 2011 amount of money (__I mean a capital only__) is unchanged and equels 8400$.

Using the same formula the first guest posted for an ordinary annuity

use n = 12 and R = .09/12 = .0075

FV=P{[1 + R]^N - 1}/ R

FV = 700 {(1.0075)^12 - 1}/(.0075) = 8755.31 after the first year....

Now this amount gets compound interest monthly for the next 12 months

8755.31 (1+.0075)^12 = $ 9576.62
