Answer:
Nominal = 8.8% yearly
Periodic = 2.2% quarterly
Effective = 9.09% compounded Quarterly
Explanation:
Bank issues the nominal Interest rate, so, 8.8% interest rate issued by the bank is the nominal.
Periodic interest rate is the interest rate for a specific period. It is calculated by dividing the annual rate with numbers of period in a year.
8.8% Interest rate is annual rate, to calculate the quarterly rate we divide it by 4.
Interest per quarter = 8.8% / 4 = 2.2%
Effective interest rate included the compounding effect.
Interest is compounded each Quarter
Effective Interest rate = ( 1 + r ) ^n = [ ( 1 + 8.8%/4 )^4 ] - 1 = 9.09%
