Interest: Definition, Functions, and what is Interest Rate?

What is Interest?

The concept of 'interest' in financial contexts is familiar to nearly everyone. Whether we're borrowing funds or stashing money in bank accounts, the dynamic of accruing or earning additional funds beyond the initial sum is inherent. Simply put, interest is the extra percentage we encounter when repaying a debt. Whether it's a personal loan, a mortgage, or any other form of borrowed capital from banks or financial institutions, the amount paid exceeds the principal borrowed, constituting the interest. This surplus, calculated as a percentage of the borrowed amount, forms a fundamental aspect of financial transactions, influencing the overall cost of borrowing and the returns on investments.

 

How Interest Functions in Borrowing

When you borrow money, repayment involves more than just the principal amount; it encompasses the concept of interest. Essentially, interest represents an additional sum, usually expressed as an annual percentage of the principal, that you must remit to the lender. This financial component applies to various loan types, including credit cards, car loans, mortgages, personal loans, and more. Grasping the intricacies of interest terms and repayment obligations is pivotal.

For example, consider a scenario where you borrow ₹20,000 from your bank with an 8 percent annual interest rate, payable over seven years. The interest on conventional bank loans is typically compounded monthly and incorporated into your monthly payments. In this revised example, the cumulative interest paid over the loan's lifespan would be approximately ₹8,960.22. This alteration emphasizes the significance of comprehending interest dynamics, as it significantly influences the overall cost and duration of the borrowing experience.
