Before you buy a house, it is necessary to understand what a $600,000 mortgage means financially. According to Bankrate, the national average 30-year fixed mortgage rate, as of August 26, 2024, is 6.53%. However, individual rates may vary based on several factors, including the borrower’s credit history and lender terms. Here’s an exhaustive picture of what to expect with monthly payments, total interest, and how amortization works.

Monthly payments on a $500,000 mortgage

The amount you’ll pay monthly depends on the interest rate and term of the loan. Here are estimates based on a range of rates for 15- and 30-year fixed-rate mortgages:

Interest Rate15-Year Term30-Year Term
5.75%$4,982$3,501
6.50%$5,227$3,792
7.00%$5,393$3,992
8.00%$5,734$4,403

For a 30-year mortgage at a 7.00% interest rate, your monthly payment is approximately $3,992, while a 15-year loan at the same rate would cost around $5,393. Choosing a shorter term means higher monthly payments but significantly less interest paid over the life of the loan.

Total interest over the life of the loan

The interest you’ll pay on a $600,000 mortgage adds up significantly over time. At a 7.00% fixed rate:

  • 30-Year Mortgage: You’ll pay $837,053 in interest, about two-thirds of the original loan amount.
  • 15-Year Mortgage: The interest totals $370,735, roughly half the interest paid on a 30-year term.

Choosing a shorter loan term can save hundreds of thousands of dollars in interest but requires a higher monthly commitment.

Understanding amortization

Amortization pays off a loan through regular, periodic payments. Early in the term, most of your payment goes toward interest. But as the principal balance decreases, more of your payment will be applied to it.

Example Amortization for a 30-Year Loan at 7.00%

  • Year 1: $41,807 in interest, $6,095 toward the principal.
  • Year 15: $31,708 in interest, $16,193 toward the principal.
  • Year 30: $1,768 in interest, $46,134 toward the principal.

By the end of the loan term, the balance reaches zero, and you’ll have paid a total of $1,437,053, including both principal and interest.

Making informed decisions

Choose between 15 years or 30 years, and then decide on their effect on monthly payments with specifics to total interest on your long-term financial plans.
