Mortgage Amount

The mortgage amount is the principal of the loan. It's how much is borrowed to purchase or refinance a home. Principal can be the purchase price or the loan amount after applying the down payment.

Example: Purchase price minus down payment

  • $800,000 purchase price
  • $160,000 down payment (20% down)
  • $640,000 mortgage amount (principal)

Interest Rate

Loan interest is the cost of the principal. It's the portion of the monthly mortgage payment that is the charge for money loaned to you. It is expressed as a percentage rate. There are many factors that impact the interest rate for loan, such as:

  • Market conditions
  • Loan-to-value (LTV) ratio
  • Borrower's credit score
  • Type of mortgage program (FHA, VA, USDA, etc.)


The term is the length of time for paying back the mortgage. Terms have an impact on interest rates. The most popular loan terms are 30 years and 15 years. 30-year mortgages carry a slightly higher interest rate than 15-year mortgages.
