What is interest as related to a mortgage loan payment?

Interest, in the context of a mortgage loan payment, refers to the cost incurred for borrowing money from a lender. When a borrower takes out a mortgage, they are essentially borrowing a large sum of money to purchase real estate, and in return, they agree to pay back that money over time with additional costs reflected as interest. This interest is essentially a fee paid to the lenders for the privilege of using their capital. It compensates the lender for the risk they take by lending money and is usually expressed as an annual percentage rate (APR).

This concept of interest is foundational in understanding how mortgages work, as it impacts the overall cost of borrowing and how monthly payments are structured. It’s important for borrowers to grasp how interest can significantly affect the total amount paid over the life of the loan.
