Definition
A fixed rate mortgage has an interest rate that stays the same for the life of the loan.
If you are comparing mortgage options, treat fixed rate mortgage as one piece of the total cost and risk picture, not a standalone detail.
Why It Matters
It matters because predictable principal and interest payments can make budgeting easier.
Simple Example
A 30-year fixed mortgage at 6.75% keeps the same interest rate unless the borrower refinances.
How to Use This Term
When you see fixed rate mortgage on a loan estimate, calculator result, or lender conversation, connect it to three practical questions: how it affects monthly payment, how it affects cash needed now, and how it affects flexibility later.
