Compare ARM vs fixed rate today 2026 using live FRED data: 30-year fixed at 6.53% and ARMs starting near 5.5%—see which loan type saves money now.
As of May 28, 2026, the 30-year fixed mortgage rate stands at 6.53% according to FRED data, while the 10-year Treasury yield sits at 4.48%, producing a 2.05% spread. These levels place 30-year fixed pricing roughly 0.28 percentage points above the 6.25% average reported in contemporaneous market summaries. Adjustable-rate mortgages (ARMs) are quoting initial rates beginning at 5.5%, creating an immediate 1.03-percentage-point discount versus the 30-year fixed benchmark.
A fixed-rate mortgage locks the interest rate for the entire loan term, shielding borrowers from future market swings. An ARM, by contrast, applies a fixed introductory rate—commonly 5, 7, or 10 years—then resets periodically based on an index plus margin. In 2026, most competitive 5-year ARMs start 0.75%–1.25% below comparable fixed loans, translating into measurable monthly savings on a $400,000 loan.
The table below illustrates estimated principal-and-interest payments for a $400,000 loan at prevailing May 2026 rates:
| Loan Type | Rate | Monthly P&I | 5-Year Total Paid |
|---|---|---|---|
| 30-yr Fixed | 6.53% | $2,531 | $151,860 |
| 5-yr ARM | 5.50% | $2,266 | $135,960 |
Over the first 60 months, the ARM saves $15,900 in payments, according to the rate differentials reported by multiple lenders.
Borrowers who plan to sell or refinance within five to seven years can capture the lower introductory rate without exposure to later resets. Markets such as Austin, Texas, and Raleigh, North Carolina, continue to show elevated listing inventories, shortening average days-on-market and supporting shorter ownership horizons. Conversely, households expecting to remain in place beyond the fixed period face the risk that rates could rise after the teaser window closes.
After the initial fixed period, ARMs typically adjust every six or twelve months using the Secured Overnight Financing Rate (SOFR) plus a fixed margin of 2.25%–2.75%. If the index climbs 1.5 percentage points, a 5.5% ARM could reach 7.0%–7.25%, exceeding today’s 30-year fixed quote. Lenders are required to disclose worst-case payment scenarios; borrowers should model a 200-basis-point increase before committing.
Redfin data shows median home prices in Denver, Colorado, rose 3.1% year-over-year through April 2026, while inventory levels remain 12% above 2025 averages. Higher price points amplify the dollar impact of even a 1% rate differential, making the ARM’s early savings more pronounced in high-cost metros.
For buyers who can confidently exit the loan within the introductory window, a 5-year ARM at 5.5% currently offers clear cash-flow advantages over the 6.53% 30-year fixed. Those planning longer-term ownership should weigh the reset risk and may prefer locking the fixed rate.
