Suppose an individual makes an initial investment of $1,400 in an account that earns 7.8%, compounded monthly, and makes additional contributions of $100 at the end of each month for a period of 12 years. After these 12 years, this individual wants to make withdrawals at the end of each month for the next 5 years (so that the account balance will be reduced to $0). (Round your answers to the nearest cent.)
(a) How much is in the account after the last deposit is
made?
$
(b) How much was deposited?
$
(c) What is the amount of each withdrawal?
$
(d) What is the total amount withdrawn?
Future value of initial investment $1,400 in an account that earns 7.8%, compounded monthly
FV (Initial investment) = 1400*(1+0.078/12)^144 = $3558.87
For finding future value (after 12 years) of the monthly contribution we use a financial calculator,
PV = 0
PMT = 100
N = 144 (12 years*12 months = 144 periods)
I/Y = 7.8/12 (Interest per period)
cpt FV, we get
FV = -23723.85
Hence, the value of monthly deposits after 12 years = 23723.85
Total value of deposits after 12 years = $(23723.85+3558.87) = $27282.72
Now, this total value of deposits is withdrawn monthly over a period of 5 years
We use a financial calculator to find PMT
PV = -27282.72
FV = 0
I/Y = 7.8/12 (Interest per period)
N = 60 (5 years*12 months = 60 monthly payments)
cpt PMT, we get
PMT = 550.59
Hence, amount of each withdrawal for 5 years = $550.59
How much is in the account after the last deposit is made? => $27282.72
How much was deposited? = 1400 + 144*100 = $15800
What is the amount of each withdrawal? => $550.59
What is the total amount withdrawn? = $550.59*5*12 = $33035.4
