The 30-year mortgage rate averaged 7.40% in Freddie Mac’s latest weekly survey, unchanged from the week before and well above the 6.27% buyers saw a year earlier. The 15-year fixed rate was 6.71%, down slightly from 6.73%, against 5.52% a year ago. Those are the numbers for Oct. 15, and the next update lands Thursday at noon Eastern.
A gap of about 1.1 percentage points sounds abstract until you put it on a real loan. This guide does that math, explains what moves the number, and lists what to check before you lock a rate. It is general information, not financial advice.

What Freddie Mac reported on the 30-year mortgage rate
Freddie Mac’s Primary Mortgage Market Survey shows the 30-year fixed at 7.40% as of Oct. 15, flat from last week and up from 6.27% a year earlier. The 15-year fixed is 6.71%, down from 6.73% last week and up from 5.52% a year ago. The survey is published on Thursdays at noon Eastern, and each figure averages the rates offered from the prior Thursday through Wednesday.
Two cautions. First, this is an average, so your quote can be higher or lower depending on your credit score, down payment, loan type and the lender. Second, it is a weekly snapshot. A rate you see quoted today may differ from the survey, which looks backward over several days.
What the gap costs on $400,000
Here is the worked example, using the standard amortization formula and counting principal and interest only, not taxes, insurance or fees. On a $400,000 loan over 30 years, a 7.40% rate means a payment of about $2,770 a month. At last year’s 6.27%, the same loan would have cost about $2,468. That is roughly $301 more each month, or about $3,617 a year.
The lifetime picture is larger. At 7.40%, total interest over 30 years on that loan comes to about $597,000. At 6.27%, it would be about $489,000, a difference of roughly $108,500. On a smaller $300,000 loan, the monthly gap is about $226, or around $2,700 a year.
These are our own calculations from the published rates, and they assume the loan is held for the full term. Most borrowers sell or refinance sooner, which changes the lifetime cost, but the monthly payment gap is real from the first day.
The 15-year trade-off
The 15-year rate is lower, 6.71%, but the payment is higher because the loan is paid off in half the time. On the same $400,000, a 15-year loan at 6.71% works out to about $3,531 a month, compared with about $2,770 on the 30-year at 7.40%. The difference is roughly $761 a month.
What you get for it is a much smaller interest bill: about $236,000 over 15 years, against about $597,000 over 30. Whether that is worth it depends on your budget, not on the headline rate. A payment you cannot sustain is the most expensive option of all, and the lower rate does not help if it stretches your monthly cash flow too thin. To see how a payment translates into a home price, our worked example of how much house you can afford walks through it.
What moves the rate
Mortgage rates tend to follow the 10-year Treasury yield more closely than the Fed’s own policy rate. A Schwab market update from Oct. 16 had the 10-year yield around 5.10%, after dipping on Thursday to its lowest level since Sept. 23, and noted that the move helped rate-sensitive sectors recover. Analysts quoted there said it was too early to say whether the yield decline would last.
This week’s data could nudge it. Kiplinger’s calendar lists the NAHB housing index on Monday, September housing starts and pending home sales on Tuesday, and consumer sentiment on Friday. None of those sets the 30-year mortgage rate directly, but a surprise can move Treasury yields, and mortgage lenders reprice quickly when yields move.
Why timing the market is hard
It is tempting to wait for a lower rate. The trouble is that the same forces that push mortgage costs down, such as slower growth, can also soften home prices, hiring and your own income. Meanwhile, inflation has been running hot: the Bureau of Labor Statistics reported 3.7% annual consumer price growth for September, which is why traders have been debating further Fed hikes. For the bigger picture on that debate, see our piece on savings rates after the Fed hike.
Nobody can say where the 30-year mortgage rate will be in three months. What you can control is how much payment you can carry, how large a down payment you can make and how clean your credit is. If a home fits your budget at today’s rate, a later drop becomes a refinance opportunity. If it only fits at a hoped-for lower rate, that is a sign to keep saving and shopping, not to stretch.
Four checks before you lock
If you are shopping, the practical steps matter more than guessing the weekly direction. Get written quotes from at least three lenders on the same day, because rates and fees vary. Compare the annual percentage rate, not just the headline rate, so points and lender fees are included. Ask how long the quote is valid and what a lock costs if closing is delayed. And ask about the cost of a later refinance, since some borrowers plan to refinance if rates fall.
It also helps to know your own numbers first: your credit score, your down payment and the monthly payment you are comfortable with after taxes and insurance. A lender can only quote against what you bring, and a small improvement in credit score can sometimes move a quote more than a week of market drift.
Editor’s take
Watch the 10-year yield, not the weekly survey. The Freddie Mac number looks backward, while the yield moves daily and tells you where lenders are heading. If you are deciding whether to lock, a quote you can afford at today’s 30-year mortgage rate is worth more than waiting for a drop that nobody can promise.
What to watch next: Thursday’s survey at noon Eastern, and whether the 10-year yield holds below last week’s levels.
