The average 5-year/6-month adjustable-rate mortgage (ARM) interest rate is 6.50% in October 2025, according to Curinos data. However, your rate may be higher or lower than that, depending on your individual situation.
If you're planning to take out an ARM, here's what you need to know about current rates and trends, plus other details to consider.
Since late 2023, ARM loan rates have generally hovered between 6% and 7%. These rates tend to track with the yield on the 10-year Treasury note, which shifts based on investor expectations around monetary policy and broader economic signals.
Right now, lingering uncertainty around inflation and U.S. tariff policy is keeping rates elevated. When markets feel unstable, investors demand higher bond yields, driving mortgage rates up. Until there's more economic clarity, significant rate drops are unlikely.
| Mortgage | Rate | APR | Monthly Payment | 
|---|---|---|---|
| 30-year fixed, conventional | 6.78%* | 6.90% | $2,152.41 | 
| 15-year fixed, conventional | 5.79%* | 5.98% | $2,668.11 | 
| 5-year/6-month ARM | 6.50%* | 7.01% | $5,853.99 | 
| 30-year fixed, jumbo | 6.47%** | 6.61% | $4,433.22 | 
| 30-year fixed, FHA | 6.13%** | 6.25% | $2,032.34 | 
| 30-year fixed, VA | 5.89%** | 6.00% | $1,987.07 |

Mortgage interest rates plunged to historic lows during the pandemic as the Federal Reserve took aggressive steps to support the housing market. But that trend reversed in 2022 when the Fed began raising the federal funds rate to fight surging inflation.

While mortgage rates aren't directly tied to the Fed's rate, they're heavily influenced by expectations around Fed policy, which impacts the 10-year Treasury yield. After reaching a peak in October 2023, rates have largely plateaued amid persistent economic uncertainty.

ARMs work a little differently than fixed-rate mortgages (FRMs). Rather than offering a set rate for the life of the loan, ARMs provide an initial fixed rate for a set period of time—usually three to 10 years. Once this initial fixed period elapses, the loan's rate can fluctuate based on market conditions and affect the cost of the homeowner's monthly mortgage payment.
The initial rate is typically lower compared to a fixed-rate mortgage and is based on the following factors:
After your initial fixed period ends, your rate may change based on market conditions and your loan's caps on interest rate adjustments.
To qualify for an ARM, you'll need to meet certain financial and credit criteria set by the lender. While requirements can vary by lender and loan type, here are some common qualifications you'll need to satisfy:
There are many different types of ARMs from which you can choose. However, we'll only cover the most common options, which differ based on the length of the initial fixed period and how often the interest rate adjusts:

Before you apply for an ARM—or any type of loan for that matter—it's important to carefully consider the product's benefits and drawbacks, particularly how they apply to your situation. Here's what to keep in mind.
Lower initial interest rate: ARMs typically offer lower introductory rates than fixed-rate mortgages, which can translate to significant savings in the early years of the loan. This can be ideal if you plan to move or refinance before the rate adjusts.
Potential for falling rates: If market interest rates drop after your fixed period ends, your mortgage rate and monthly payment could go down. This can result in long-term savings without the need to refinance.
Greater affordability: Because of the lower starting rate, you may qualify for a larger loan or a more expensive home than you would with a fixed-rate mortgage. This can expand your buying power during the introductory period.
Rate and payment uncertainty: Once the fixed period ends, your rate can fluctuate based on market conditions. If rates rise, so will your monthly payment, sometimes significantly.
Complex terms: ARMs come with caps, margins and indexes that determine how and when your rate changes. These can be confusing and make it harder to predict future payments.
Risk of payment shock: When your loan adjusts, your new rate could increase your payment by hundreds of dollars per month. If you're not prepared, it could strain your budget—or worse, put you at risk of default.

While some factors that affect ARM rates are beyond your control, there are several ways to improve your chances of securing the lowest possible rate:
While ARMs can offer low initial rates, they're not the right fit for everyone. Here are some alternatives to consider:
An adjustable-rate mortgage can be a valuable tool for the right borrower—especially if you're looking for a lower initial payment and don't plan to stay in your home for long. However, it also comes with uncertainty, and it's essential to understand how your rate could change in the future.
Before applying, take time to assess your financial situation, long-term plans and risk tolerance. If you're unsure whether an ARM is right for you, consider speaking with a mortgage professional or financial advisor to explore your options.
