October 8, 2026 Mortgage Costs: Five-Year View

Freddie Mac’s October 8, 2026 release put the average 30-year mortgage rate at 7.40%, up from 7.28% a week earlier. For a hypothetical $400,000 loan with a 30-year term, that change adds about $33 a month and $2,421 in interest over five years. Borrowing costs rise by more than the extra payments because the higher-rate loan also leaves more principal unpaid.

What the October 8 mortgage rates measure

The weekly increases were 0.12 percentage point for the 30-year rate and 0.13 percentage point for the 15-year rate. Freddie Mac’s release and comparisons

The Primary Mortgage Market Survey (PMMS) uses application activity from the preceding Thursday through Wednesday, making October 1–7 the measurement window for this release. It reflects qualifying applications submitted through Freddie Mac’s Loan Product Advisor, rather than a single day’s closing rates. PMMS methodology

The benchmark focuses on conventional, conforming, fully amortizing purchase loans for borrowers with excellent credit and 20% down. Freddie Mac describes that borrower profile in its release. It does not establish the rate available to a particular household. Use our mortgage-rate data for market context; compare actual lender offers separately.

Five-year interest with the loan held constant

This illustration compares two hypothetical new $400,000 mortgages, each with a fixed rate and a 30-year term. Only the interest rate changes.

Assume 60 scheduled monthly payments, no extra principal payments and no refinancing. Set points, loan fees, lender credits, prepaid interest and mortgage insurance to zero; no costs are financed. Property taxes, homeowners insurance and other ownership expenses are excluded. These assumptions isolate amortization and do not describe an available loan offer.

The Housing Current calculations using the two published rates. Calculations retain full precision until display rounding; lender schedules using rounded payments can differ slightly.

Each month’s interest equals the opening balance multiplied by the annual rate divided by 12. The rest of the payment reduces principal. At the higher rate, even the larger payment leaves less money for principal reduction.

Use the mortgage payment calculator with $400,000, 30 years and each rate to check the monthly principal-and-interest comparison. Budget taxes and insurance separately.

Why payments and borrowing costs differ

At 7.40%, the household pays $166,171.15 over 60 months, but $21,908.06 of that repays borrowed money. The interest expense is $144,263.09. Principal repayment remains a cash requirement, even though it reduces the debt rather than paying for the use of the money.

Across the two scenarios, the higher rate produces $1,960.20 in additional payments and leaves $460.49 more principal outstanding. Together, those differences account for the $2,420.69 increase in interest.

For a household expecting to sell or refinance after five years, comparing payments alone misses that remaining-balance difference. These are scheduled balances immediately after payment 60, not lender payoff quotes or forecasts of the home’s value.

Read both numbers in the Loan Estimate’s five-year comparison

The Loan Estimate carries this distinction between payments and principal into a broader cost comparison. On page 3, the Comparisons section has an “In 5 Years” entry with two amounts. The first combines scheduled principal, interest, mortgage insurance and loan costs; the second shows principal repaid. The applicable H-24 model forms display both amounts.

Loan costs include origination charges and required services in the Loan Costs section on page 2. Mortgage insurance belongs in the five-year comparison when applicable, including prepaid or escrowed mortgage insurance. Ongoing property taxes and homeowners insurance are outside this measure, even when collected through escrow. Regulation Z, §1026.37(f) and (l)

Subtract principal repaid from the first amount to isolate the disclosed five-year borrowing cost, as CFPB recommends when comparing offers. Under our illustration’s assumptions, that subtraction leaves only interest. An actual Loan Estimate includes the costs applicable to that offer.

Add the fees before choosing a quote

PMMS does not report average discount points or origination fees. Its application rates are not lender commitments, so 7.40% should not be presented as a guaranteed offer with zero points. Freddie Mac’s methodology explanation, published November 3, 2022

In a separate hypothetical quote comparison, suppose the 7.28% loan required $3,000 more in upfront fees than the otherwise identical 7.40% loan. With those fees paid in cash and all other assumptions unchanged, its $2,420.69 interest saving would leave it $579.31 more expensive over five years. Its monthly payment would still be lower.

To compare actual offers, request matching loan amounts, terms and products with comparable quote dates and lock periods. Review points, origination and third-party charges, lender credits, mortgage insurance, and closing-date prepaid interest. Ask the loan officer to reconcile these with the five-year figures and cash needed at closing. The CFPB Loan Estimate explainer identifies where these charges and credits appear; our mortgage pricing coverage provides broader context.

If the household expects to keep the loan for a different period, have the lender calculate costs and remaining principal for that period before deciding whether an upfront fee is worth paying.
