1.) If the account earns an interest rate of 24%
compounded monthly, find the effective rate of interest:
A. Compounded daily 360 days
B. Compounded daily 365 days
C. Compounded weekly
D. Compounded monthly
E. Compounded quarterly
F. Compounded semi-annually
G. Compounded annually
2.) What is the effective annual interest rate for a
nominal interest rate of 24% compounded continuously?
1)
Effective interest rate = 24% per annum
a) If it is compounded daily (360 days)
Daily rate of interest = 24% / 360 = 0.000667
Annual effective rate of interest [1 + 0.000667]^360 = 1.2711 which is 27.11% per annum
b) If it is compounded daily (365 days)
Daily rate of interest = 24% / 365 = 0.000548
Annual effective rate of interest [1 + 0.000548]^365 = 1.2711 which is 27.11% per annum
c) If it is compounded weekly (52 weeks)
Daily rate of interest = 24% / 52 = 0.004706
Annual effective rate of interest [1 + 0.004706]^52 = 1.2765 which is 27.65% per annum
d) If it is compounded monthly (12 months)
Daily rate of interest = 24% / 12 = 0.02
Annual effective rate of interest [1 + 0.02]^12 = 1.2682 which is 26.81% per annum
e) If it is compounded quartrely (4 quarter)
Daily rate of interest = 24% / 4 = 0.06
Annual effective rate of interest [1 + 0.06]^4 = 1.2625 which is 26.25% per annum
f) If it is compounded semi annually (2 semi annual)
Daily rate of interest = 24% / 2= 0.12
Annual effective rate of interest [1 + 0.12]^2 = 1.2544 which is 25.44% per annum
g) If it is compounded annually
Daily rate of interest = 24% / 1 = 0.24
Annual effective rate of interest [1 + 0.24]^1 = 1.24 which is 24% per annum
2) Interest rate of 24% compounded continuously
Annual effective rate of interest = e^(r * t)
wher value of e = 2.71828
r = 0.24
t = 1
Annual effective rate of interest = 2.71828^*0.24 = 1.2713 which is 27.13%
