If $12,000 is invested at 2.5% for 20 years, find the future value if the interest is compounded the following ways. (Round your answers to the nearest cent.)
(a) annually
$
(b) semiannually
$
(c) quarterly
$
(d) monthly
$
(e) daily (N = 360)
$
(f) every minute (N = 525,600)
$
(g) continuously
$
(h) simple (not compounded)
$
PV = $ 12000
Tenure (t) = 20 years
interest rate (i) = 2.5% p.a.
(a) If interest rate compounded annually,
Future value = PV x (1+i)t = 12000 x (1+2.5%)20 = $ 19,663.40
(b) If interest rate compounded semi-annually,
No of compounding in a year (N) = 2
Future value = PV x (1+i/N)t x N = 12000 x (1+2.5% / 2 )20x2 = $ 19,723.43
(c) If interest rate compounded quarterly,
No of compounding in a year (N) = 4
Future value = PV x (1+i/N)t x N = 12000 x (1+2.5% / 4 )20x4 = $ 19,753.89
(d) If interest rate compounded monthly,
No of compounding in a year (N) = 12
Future value = PV x (1+i/N)t x N = 12000 x (1+2.5% / 12 )20x12 = $ 19,774.37
(e) If interest rate compounded daily,
No of compounding in a year (N) = 360
Future value = PV x (1+i/N)t x N = 12000 x (1+2.5% / 360)20x360 = $ 19,784.31
(f) If interest rate compounded every minute,
No of compounding in a year (N) = 525,600
Future value = PV x (1+i/N)t x N = 12000 x (1+2.5% / 525600 )20x525600 = $ 19,784.66
(g) If interest rate compounded continuously,
No of compounding in a year (N) = 525,600
Future value = PV x eixt = 12000 x e0.025 x 20 = 12000 x 1.648721 = $ 19,784.66
(h) If interest rate is simple,
Future value = PV + PV x i x t = 12000 + 12000 x 2.5% x 20 = $ 18,000
Thumbs up please if satisfied. Thanks :)
