What is the difference between amortization and interest in a loan repayment plan?

Amortization is the process of paying off a loan over time through regular payments that cover both the principal amount borrowed and the interest. Interest is the cost of borrowing money, calculated as a percentage of the loan amount. In a loan repayment plan, the interest is the fee charged for borrowing the money, while amortization is the gradual reduction of the loan balance through regular payments.
