Value of the CD after 3 months is given by 300(1 + 0.03 / 4) = 300(1 + 0.0075) = 300 x 1.0075 = $302.25.
Therefore, interest for 3 months = $302.25 - $300 = $2.25
The rate of interest at which Dylan invested is 3.09%.
The practice of adding interest to the principal of a loan or deposit is known as compound interest, sometimes known as interest on principal and interest. It happens when interest is reinvested, added to the collateral for the loan rather than paid out, or when the borrower is forced to pay it, resulting in interest being created on the principal amount plus any accumulated interest the following period. Compound interest is a prominent concept in finance and economics.
Compound interest allows interest to accumulate over time, in contrast to simple interest, which does not compound because past interest is not returned to the principle for the present period.
principal =360
time =5 years
n=5×4=20 (compounded quarterly)
Amount = 420
Now: 420 = 360(1+r)²⁰
solving for r we get:
r= 0.007737
required rate percent = 0.007737×4 = 0.00193 × 100 = 3.09%
hence the simple annual interest rate is obtained by multiplying the interest per period by the total number of periods in a year is 3.09%.
