Answer:
11.61%
Explanation:
First, find the annual percentage return (APR) of this annuity. Using a financial calculator, input the following;
Recurring payment; PMT = -450
Future value ; FV = 27,000
Duration of investment ; N = 4*12 = 48 months
One -time present value; PV = 0
then compute interest rate; CPT I /Y= 0.92% (this is monthly rate)
APR = 0.92*12 = 11.035%
Effective Annual Rate (EAR) formula is as follows;
EAR = (1+[tex]\frac{APR}{m}[/tex] ) ^m -1
EAR = 1+[tex]\frac{0.11035}{12}[/tex] )^12 -1
EAR = 1.1161 -1
EAR = 0.1161 or 11.61%
