The Deal You Are Actually Making
A fixed-rate mortgage is the simplest contract in home lending. The lender quotes a rate, you lock it, and that rate never moves. Not in year five. Not in year twenty. The Consumer Financial Protection Bureau says it the same way: the interest rate is set when you take out the loan and will not change.
That is the whole product. The price of that certainty is a rate that starts higher than an adjustable-rate loan’s teaser rate. You are paying the lender to take the interest-rate risk off your shoulders.
For most buyers, that trade is worth it.
What Fixed Rates Cost Right Now
As of early June 2026, the average 30-year fixed rate is 6.48%, per Freddie Mac’s Primary Mortgage Market Survey. That survey tracks conventional, conforming purchase loans for buyers with 20% down and strong credit. Treat it as a benchmark, not a guarantee.
At 6.48%, a $400,000 loan runs about $2,523 a month in principal and interest. That number will not move for 360 payments. Your taxes and insurance will. Your principal and interest will not.
One more number that matters: the conforming loan limit. In 2026, Fannie Mae and Freddie Mac can buy loans up to $832,750 in most counties, and up to $1,249,125 in designated high-cost areas, per the Federal Housing Finance Agency. Stay under those limits and you get conforming pricing. Go over and you are shopping for a jumbo loan, which is a different conversation.
30-Year vs. 15-Year
The 30-year fixed is the default American mortgage for a reason. It spreads the principal over the longest standard term, which keeps the payment low.
The 15-year fixed flips the trade. The rate is lower and the total interest is dramatically lower, but the monthly payment is much higher because you are paying off principal twice as fast.
Here is the move most people miss: take the 30-year, then prepay it like a 15-year when cash flow allows. You get the lower required payment as a safety net and the interest savings when you can afford them. The reverse is not on offer. A 15-year loan does not let you downshift to a 30-year payment in a tight month.
Your call. But if the 15-year payment leaves no slack in your budget, that is your answer.
When Fixed Is the Right Answer
Lock a fixed rate when any of these describe you:
- You plan to stay in the home longer than five to seven years.
- Your budget has no room for a payment hike. A fixed payment is the only payment that cannot surprise you.
- Rates are at a level you can live with. Trying to time the rate market is a losing game. If the payment works today, the loan works.
If you are confident you will sell or refinance within a few years, an adjustable-rate mortgage with a lower starter rate can beat a fixed loan on total cost. That is the one situation where the ARM math genuinely competes. Everywhere else, fixed wins on sleep quality alone.
If Rates Fall Later
A fixed rate is a ceiling, not a prison. If market rates drop well below your locked rate, refinance. The new loan pays off the old one and you keep the lower rate going forward.
Here’s the catch. Refinancing is not free. Closing costs on a refinance typically run a few thousand dollars, so divide the cost by your monthly savings and make sure you will keep the loan past the break-even month. Our refinancing guide walks through the math.
Do This Before You Lock
Get Loan Estimates from at least three lenders. Federal rules require every lender to send one within three business days of your application, in an identical format. That makes comparison easy. Stack the rate, the points, and the lender fees side by side, then use our mortgage calculator to see what each offer costs per month.
A quarter point of rate on a $400,000 loan is real money over 30 years. Twenty minutes of shopping is the cheapest interest-rate hedge you will ever buy. Start with the mortgages hub to see how fixed-rate loans stack up against everything else.
