Compare ARM vs fixed rate today 2026 with live FRED data: 30-year fixed at 7.03% and 5/1 ARM at 5.25%. See which loan type saves money in the current market.
As of September 26, 2026, the mortgage market presents a clear spread between fixed-rate and adjustable-rate products. According to FRED data released on September 24, the 30-year fixed-rate mortgage sits at 7.03% while the 15-year fixed stands at 6.42%. The 10-year Treasury yield is 5.18%, creating a 1.85% spread that lenders use to price new loans.
Market reports from mid-2026 show conventional 30-year fixed rates holding near 6.250% (6.302% APR) in many regions, but the national average remains anchored at the higher FRED figure. Meanwhile, introductory 5-year ARM rates are being quoted around 5.25% in competitive markets.
The monthly payment difference is immediate. On a $300,000 loan, a 5.25% ARM saves roughly $130–$150 per month compared with a 6.00% fixed-rate mortgage. Over five years, that equals $7,800–$9,000 in cash-flow relief—capital that can be redirected to closing costs or home improvements.
However, the savings are front-loaded. After the initial fixed period, the ARM resets to an index plus margin. If short-term rates rise, the payment can exceed the original fixed-rate alternative.
Rate spreads vary by geography. In the Kansas City metro, local lenders are advertising 5/1 ARMs at 5.15% with a 2% annual cap, while 30-year fixed loans average 6.35%. In Seattle, the same 5/1 ARM is quoted at 5.40% versus a 6.55% fixed rate. These gaps illustrate how local competition and credit profiles influence the ARM versus fixed-rate decision.
Every ARM carries lifetime and periodic caps. A typical 5/1 ARM today limits annual increases to 2% and lifetime increases to 5%. Starting at 5.25%, the rate could theoretically reach 10.25% after several adjustments. Borrowers must model worst-case payments before choosing an ARM.
Fixed-rate mortgages eliminate this uncertainty. Once locked, the 7.03% rate (or whatever rate is secured) remains constant for the full 30 years, regardless of future Treasury movements.
| Loan Type | Initial Rate | 5-Year Total Interest* | Worst-Case Rate | Worst-Case Payment (Yr 6+) |
|---|---|---|---|---|
| 30-yr Fixed | 7.03% | $114,300 | 7.03% | $1,995 |
| 5/1 ARM | 5.25% | $85,200 | 10.25% | $2,520 |

An ARM is most suitable when the borrower plans to sell or refinance within the initial fixed window—typically five to seven years. Homeowners expecting income growth or planning a move for career reasons can capture the lower rate without exposure to later resets.
Conversely, buyers who intend to stay in the property beyond the initial period, or who prioritize payment certainty for budgeting, are better served by locking in a fixed rate today.
With the 30-year fixed at 7.03% and competitive 5-year ARMs near 5.25%, the decision hinges on time horizon and risk tolerance. Homeowners who will remain in the property for seven or more years should favor the fixed-rate mortgage. Those with shorter ownership plans or strong refinancing flexibility may benefit from the ARM’s lower initial payments.
