Mortgage Rates for August 6, 2026: Terms Diverge

Mortgage rates moved in opposite directions in Freddie Mac's August 6, 2026 release: the 30-year fixed average rose to 6.69%, while the 15-year average fell to 6.01%. For the same loan amount, the lower 15-year rate still means a substantially higher required monthly payment. Both figures are weekly benchmarks for a defined borrower profile, not rates a lender has committed to offer you.

The weekly changes and their measurement window

A basis point is 0.01 percentage point. The gap between the two averages widened from 0.62 to 0.68 percentage point. Saying simply that “mortgage rates rose” misses the decline in the 15-year average; the release does not establish why the terms diverged.

Under Freddie Mac's collection schedule, this release covers applications from 12:00 a.m. ET July 30 through 11:59 p.m. ET August 5. Thursday publication does not make it a Thursday trading snapshot. Market reactions on August 7 fall outside that window and cannot be reflected in these averages.

For comparisons over time, keep the term and survey consistent. Our mortgage rate reports follow those releases.

Which borrowers does PMMS represent?

The Primary Mortgage Market Survey, or PMMS, uses applications submitted through Freddie Mac's Loan Product Advisor underwriting system. It targets conventional, conforming home purchase loans for borrowers with excellent credit putting 20% down. Scheduled payments fully repay these mortgages by the end of the term.

Freddie Mac's methodology published November 3, 2022 defines the sample more precisely: owner-occupied, one-unit properties, FICO scores of at least 740 and loan-to-value ratios from 75% through 80%, corresponding to down payments of 20% to 25%.

A buyer putting less down or purchasing an investment property falls outside that profile. Application rates are not lender commitments, and some applications never become closed loans.

What the shorter term changes in dollars

Consider a hypothetical $400,000 mortgage on a $500,000 home, with $100,000 down. The calculation applies the August 6 averages as fixed interest rates and assumes equal monthly payments through maturity, with no extra principal payments, refinancing or early payoff.

The figures exclude property taxes, homeowners insurance, mortgage insurance, association dues, points and other closing costs. No fees are financed. Excluding points from the calculation does not mean either survey rate is available without points.

The Housing Current calculations using the release's rates. Monthly payments are rounded to cents; total interest is calculated before rounding and shown to the nearest dollar.

Repaying principal in half as many installments more than offsets the lower rate: the 15-year loan requires about $799 more each month, or roughly 31% more. In return, the borrower retires the debt 15 years earlier and pays about $320,000 less interest over the respective full terms.

The longer term leaves more room in the monthly budget; the shorter term commits more cash to faster repayment. The full-term interest difference is not a forecast of savings for someone who sells or refinances early, and it does not account for the time value of money.

By comparison, the week's rate changes have a much smaller effect on payments. On the same $400,000 balance, the 30-year payment would rise about $7.95 from the previous week's rate, while the 15-year payment would fall about $6.49. In this example, the term choice changes required cash flow far more than the week's rate movement.

Why a lender quote can differ from the survey

Credit, down payment, loan size, location and loan type can all affect an individual offer, as the CFPB explains in its guide to mortgage rate factors.

The rate also reflects choices about upfront costs. Paying discount points can lower the interest rate in exchange for an upfront charge; lender credits can reduce upfront costs in exchange for a higher rate. Freddie Mac's PMMS FAQs say the survey no longer reports average fees and points because lenders do not consistently supply them. The published average therefore cannot tell you the cash needed to obtain a particular rate.

Timing matters, too. A later lender quote may reflect newer conditions: the CFPB notes that mortgage rates can change daily or even hourly. A rate lock generally protects the quoted rate through its specified period, provided the application stays unchanged and the loan closes on time.

To compare offers, request the same loan amount, term and down payment from competing lenders, with matching lock periods and a consistent approach to points. Compare offers issued close together, then review the required payment, lender charges, credits and cash to close. The CFPB's Loan Estimate comparison guidance explains those distinctions; our mortgage pricing coverage provides broader context.

For an August 7 pricing conversation, label the PMMS figure with its survey week and present a separately dated lender quote showing costs and lock status.
