It is a classic Ordinary Annuity saving plan. The general formula is
FV = , (1)
where FV is the future value of the account; P is your annual payment (deposit); r is the annual percentage rate presented as a decimal;
n is the number of deposits (= the number of years, in this case).
Under the given conditions, P = 5000; r = 0.08; n = 10. So, according to the formula (1), you get at the end of the 10-th year
FV = = $72432.81.
Note that you deposit only 10*$5000 = $50,000. The rest is the interestwhat the account earns/accumulates in 10 years
72432.81 - 50000 = 22432.81 dollars.
