Loan Basics

What is a Loan

A loan is money you borrow from a lender that you agree to repay over time. Most loans include interest, which is the cost of borrowing. Loans are usually repaid in fixed monthly payments over a set period.

What is Interest Rate

The interest rate is the percentage charged on the amount you borrow. It determines how much extra you’ll pay on top of the original loan. A lower interest rate means lower overall cost, while a higher rate increases the total amount you repay.

What is Monthly Payment

Your monthly payment is the fixed amount you pay each month toward your loan. It usually includes both the loan amount (principal) and the interest. The size of your payment depends on the loan amount, interest rate, and loan term.

What is Loan Term

The loan term is the length of time you have to repay the loan. It can range from a few months to many years. Longer terms often mean lower monthly payments but higher total interest paid over time.
