Quarter-end payments of $1,480 are made to settle a loan of $32,260 in 8 years. What is the effective interest rate?
Information provided:
Quarterly payment= $1,480
Present value= $32,260
Time= 8 years*4= 32 quarters
The question is first solved by computing the nominal interest rate.
The nominal interest rate is computed by entering the below in a financial calculator:
PMT= 1,480
N= 32
PV= 32,260
Press the CPT key and I/Y to calculate the nominal interest rate.
The value obtained is 2.5169
Therefore, the nominal interest rate is 2.5169%*4= 10.07%.
Effective annual rate is calculated using the below formula:
EAR= (1+i/n)^n-1
Where i is the interest rate and n is the number of compounding periods in one year.
EAR= (1+0.1007/4)^4-1
= 1.1046-1
= 0.1046*100= 10.46%
Therefore, the effective annual rate is 10.46%.
In case of any query, kindly comment on the solution.
