Mortgage Calculator: Here’s How Much You Need To Buy a $415K Home at a 6.48% Rate

Mortgage rates retreated from their nine-month-high peaks Thursday as the uneasy ceasefire between the U.S. and Iran cooled global energy prices, easing pressure on bond markets and borrowing costs.

The average rate on 30-year fixed home loans decreased to 6.48% for the week ending June 4, down 5 basis points from 6.53% the previous week, according to Freddie Mac. For perspective, rates averaged 6.85% during the same period in 2025.

So what does this mean for homebuyers? Using the Realtor.com® mortgage calculator, we can take a look at how the math plays out for an average-priced home in the country, currently standing at $415,000.

All examples assume a 30-year fixed mortgage and include principal and interest only, excluding property taxes, homeowners insurance, and mortgage insurance.

Monthly mortgage payment today with a 20% down payment

For a homebuyer eyeing the current median price of $415,000, a 20% down payment results in a loan amount of $332,000.

At today’s 6.48% rate, the monthly principal and interest payment is approximately $2,094. This reflects an $11 monthly reduction from the previous week’s payment of $2,105.

Compared to the 6.85% average from June 2025, which would have required a $2,175 monthly payment for a home at this price, today’s buyers are saving $81 every single month.

Monthly mortgage payment today with a 3.5% down payment

The savings are also significant for those using FHA loans with a 3.5% down payment.

On a $415,000 home, an FHA borrower would finance roughly $400,475. At today’s 6.48% rate, the monthly principal and interest payment comes to approximately $2,526. This reflects a $13 decrease from last week's monthly cost of $2,539.

When viewed against the 6.85% rates of June 2025, where the monthly payment for this loan amount sat at $2,624, today’s FHA borrowers are keeping an extra $98 in their pockets every month.

Looking back at the October 2023 peak of 7.79%, where the payment for a home at this price reached $2,880, the monthly savings sit at $354.

Long-term savings over 30 years

The long-term financial benefits of today's rates compared to historical highs remain visible when looking at the total cost of the loan over 30 years.

A buyer with a 20% down payment at today’s 6.48% rate will pay a total of $753,876 in principal and interest over the life of the mortgage. This remains a distinct contrast to the October 2023 peak of 7.79%, when the total cost for that same $332,000 loan would have reached $859,562.

By securing a mortgage at today’s rate instead of that peak, a homebuyer effectively avoids $105,686 in interest charges over the 30-year term.

FHA borrowers see a similar trajectory of long-term savings.

Financing the current median-priced home at today's 6.48% rate results in a lifetime payment of $909,363 for principal and interest. If that same loan had been locked in at the 7.79% peak in late 2023, the total cost would have climbed to $1,036,847.

This represents a total long-term savings of $127,484 for FHA buyers. While the market remains sensitive to ongoing geopolitical developments, this week's downward drift shows that current options still provide a measurable edge over the peak extremes of recent years.
