Compare ARM vs fixed rate today 2026: current 30-year fixed at 6.4% and 5/1 ARM at 5.6% show a 0.50-0.75% spread—see which option fits your timeline.
On July 8, 2026, the average 30-year fixed-rate mortgage sits at 6.4% while the 5/1 ARM averages 5.6%, according to live market data. The 0.80-percentage-point gap translates into roughly $190 less per month on a $350,000 loan during the initial fixed period of the ARM. That spread has remained between 0.50% and 0.75% for most of the year, giving borrowers a clear numerical incentive to evaluate adjustable-rate products.
A fixed-rate mortgage locks the interest rate for the entire term, so principal-and-interest payments never change. An ARM, by contrast, holds a below-market rate for an introductory period—commonly three, five, seven, or ten years—then resets periodically based on an index plus margin. After the teaser period, the new rate can rise, fall, or stay flat depending on prevailing conditions.
| Mortgage Type | Initial Rate | Monthly P&I (first 60 months) | Total Interest (first 5 years) |
|---|---|---|---|
| 30-year Fixed | 6.40% | $2,189 | $65,340 |
| 5/1 ARM | 5.60% | $2,001 | $48,060 |
The table above uses today’s posted averages and assumes a 30-year amortization schedule. Borrowers who keep the ARM past year five face reset risk; those who refinance or sell before the adjustment window avoid it.
Homeowners who expect to move or refinance within five years can capture the lower rate without exposure to future resets. Per FRED data, mortgage rates have fallen from 7.1% in late 2025 to the current 6.4% level, illustrating the possibility of further declines. If rates drop to 5% within three years, an ARM borrower’s payment would automatically decrease at the next adjustment—provided the loan’s caps allow it.
Buyers planning to stay in the home longer than seven years, or those on fixed incomes, generally prefer rate certainty. Even a modest 2-percentage-point rise at the first reset can erase the initial savings and increase monthly outlays by several hundred dollars. Fixed-rate loans eliminate that variable.
Rate quotes vary modestly by geography. In Texas metro areas, the 5/1 ARM spread versus the 30-year fixed is currently 0.65%. In California coastal counties the same spread is 0.55%, reflecting higher average loan sizes and slightly tighter ARM pricing.

Most 5/1 ARMs today carry a 2/2/5 cap structure: the rate can rise no more than 2 points at the first adjustment, 2 points per subsequent adjustment, and 5 points over the life of the loan. These limits provide a ceiling, yet they still allow a jump from 5.6% to 7.6% in the worst-case scenario.
For buyers confident they will exit the loan within five years, the 5/1 ARM at 5.6% offers measurable monthly savings versus the 6.4% fixed rate. Borrowers intending to hold the property longer or who prioritize payment stability should select the fixed-rate option.
