Explanation / Answer

Future value of annuity due can be computed as:

FV = (1+r) x P x [(1+r) n – 1/r]

P = Periodic cash flow = $ 200

r = Rate per period = 3 % p.a. or 0.03/12 =0.0025

n = Numbers of periods = 90

FV = (1+0.0025) x $ 200 x [(1+0.0025)90 – 1/0.0025]

      = (1.0025) x $ 200 x [(1.0025)90 – 1/0.0025]

     = (1.0025) x $ 200 x [(1.251971136 – 1)/0.0025]

     = (1.0025) x $ 200 x (0.251971136/0.0025)

     = (1.0025) x $ 200 x 100.7884543

     = $ 20,208.08508 or $ 20,208.09

Balance in the account will be $ 20,208.09 after 90th deposit.
