Interest Rate

An interest rate is the percentage a lender charges for borrowing money. With a mortgage, the interest rate determines how much interest is included in each payment, alongside principal repayment.

Interest rates can be fixed for a term or change over time in variable or adjustable structures. Even small rate differences can have a significant impact when applied to large balances over many years.

Why this matters:

Rate differences can look minor on paper but add up to meaningful dollars over time. Understanding how rates work helps borrowers compare offers beyond just the headline number.
