5. Describe the difference between simple interest and compound interest?
Simple Interest is applied yearly and compound interest is applied quarterly.
Simple interest is less than 10% and Compound interest is above 10%.
Compound Interest is calculated only on the principal amount of a loan. Simple Interest is calculated on the principal amount and also on the accumulated interest of previous periods, and can thus be regarded as “interest on interest.”
