A 15-year fixed mortgage is having a moment again. Rates on the shorter term have stayed meaningfully below 30-year pricing, and plenty of homeowners who refinanced into a 3% loan years ago are now staring at a very different question: is it worth paying up each month to be done in half the time?
Here is what 15-year fixed mortgage rates today actually look like, what they cost in dollars rather than percentages, and where the math stops working in your favor.
Where 15-year fixed mortgage rates sit right now
National averages for the 15-year fixed have been bouncing around the high 5s to low 6s, depending on the week and the survey you read. Freddie Mac’s weekly tally is a decent benchmark, but it assumes a borrower with 20% down, a strong credit score, and no discount points. Your actual quote could land 40 to 60 basis points below that if you’re a clean file, or a full point above it if you’re self-employed with a 680 score and a 10% down payment.
Two things move the number more than people expect. The first is points: paying one point up front typically buys you 25 to 30 basis points off the rate, which on a $320,000 loan is roughly $3,200 for a payment reduction of about $50 a month. The second is the lender itself. On any given Tuesday, quotes on the same scenario can vary by 0.375% between a big-box bank, a credit union, and an online broker. That spread is worth more than most borrowers realize.
Why the 15-year always prices lower than the 30-year
Part of it is simple risk. An investor buying a 15-year loan gets their principal back in half the time, which means less exposure to rate swings and inflation over the life of the bond. Shorter loans also build equity fast, so if a borrower defaults in year four, there’s more cushion before the lender takes a loss.
The rest is that you’re paying for the privilege with cash flow. A lower rate on a shorter term doesn’t make the loan cheaper in monthly terms; it makes it more expensive. People routinely see the percentage and assume the payment shrinks. It doesn’t. For a closer look at why the shorter loan is often misread, this breakdown of why a 15-year fixed is worth a second look gets into the nuance.
The math on a $320,000 loan
Numbers make this concrete. Take a $320,000 mortgage, 20% down on a $400,000 house.
- 15-year fixed at 5.90%: principal and interest of about $2,683 a month. Total interest paid over the life of the loan: roughly $163,000.
- 30-year fixed at 6.60%: principal and interest of about $2,044 a month. Total interest: roughly $416,000.
The gap is $639 a month and about $253,000 in interest. That’s the trade in one line. You buy a quarter of a million dollars in interest savings with $639 of monthly cash flow, and you get there in 180 payments instead of 360.
What that line doesn’t show is everything else the money could have done. If you took the $639 and put it into a broad index fund returning 7% a year for 15 years, you’d end up with something in the neighborhood of $200,000 before taxes. Suddenly the interest savings look less like free money and more like a choice between two reasonable strategies. A careful accounting of the real cost of halving your term is worth reading before you commit.
Who the 15-year fits, and who ends up regretting it
It tends to work when:
- Your housing payment stays under about 25% of gross monthly income even at the higher figure.
- You already have six months of expenses set aside and aren’t raiding savings to close.
- Your income is stable and unlikely to drop, like a tenured teacher or a partner in an established practice.
- You’re within roughly ten years of retirement and want the mortgage gone before you stop working.
- You’d otherwise spend the difference rather than invest it.
It tends to backfire when:
- The new payment eats the emergency fund or pushes you past 36% total debt-to-income.
- You’re early in your career with volatile income or a likely relocation in five years.
- You have higher-interest debt sitting on a credit card at 22%.
- You’d be house-poor in a way that makes maintenance and repairs stressful.
There’s a middle path that gets overlooked: take the 30-year for flexibility and make extra principal payments when cash allows. You keep the lower required payment as a safety valve, and you can still finish early. If you’re weighing which structure actually suits your situation, these questions to ask before choosing a 30-year fixed mortgage are a useful gut check.
How to shop today without burning a week
Get quotes from at least four lenders on the exact same day and on the exact same scenario: same loan amount, same down payment, same lock period, same points. Anything else and you’re comparing apples to aircraft.
Ask each one for a written Loan Estimate, not a verbal rate. Verbal quotes conveniently forget to mention origination fees, and a 5.75% rate with $5,800 in fees can be worse than a 5.95% rate with $900. Compare the APR, which folds costs into a single number, but don’t rely on it alone: APR assumes you keep the loan for the full term, and most people don’t.
Lock periods matter too. A 30-day lock is usually free; a 60-day lock might cost 0.25% of the loan, which is $800 on a $320,000 mortgage. If your closing is six weeks out, pay for the longer lock rather than gamble on a rate that could move against you. There’s a solid framework for this in this step-by-step walkthrough to locking the best rate.
Four numbers to get in writing before you sign
1. The zero-point rate. This is your baseline. Everything else gets measured against it.
2. The one-point rate and its break-even month. Divide the cost of the point by the monthly savings. If a $3,200 point saves $50 a month, you break even in 64 months. Sell before then and you’ve lost money.
3. The lender credit option. Some lenders will give you a slightly higher rate in exchange for covering closing costs. On a short-term loan that you plan to keep, the credit is often the better deal, because you’re not paying interest on it for 15 years.
4. The total closing costs, itemized. Title insurance, appraisal, recording fees, and prepaid escrow all show up at the end. A rate that looks 0.125% better can vanish behind $2,000 in extra fees.
Run those four numbers side by side across your quotes and the choice usually makes itself. The lowest advertised rate is rarely the cheapest loan, and on a 15-year term the difference compounds for 180 payments.
