An adjustable-rate mortgage, or ARM, is a home loan that has an initial, low fixed-rate period of several years. After that, for the remainder of the loan term, the interest rate resets at regular intervals. The caps on your adjustable-rate mortgage are the first line of defense against massive increases in your monthly payment during the adjustment period. They come in handy, especially when rates rise rapidly — as they have the past year. The graphic below shows how rate caps would prevent your rate from doubling if your 3.5% start rate was ready to adjust in June 2023 on a $350,000 loan amount. With this type of mortgage, the actual indexed rate is fixed for the first three years of the loan, and then adjusts every year thereafter, a sort of hybrid between a fixed rate and an adjustable rate.

Is an adjustable-rate mortgage right for you?

Yes, you always have the option to refinance an ARM into a fixed-rate loan — as long as you can qualify based on your credit, income and debt. You can use the savings to pay off your mortgage faster and build home equity. Alternatively, you can use the funds for other financial goals, like saving for college or retirement.

Adjustable-Rate Mortgage: What an ARM Is and How It Works

The interest on your loan will be whatever the index rate is, plus a margin the lender adds. To make sure you can repay the loan, some ARM programs require that you qualify at the maximum possible interest rate based on the terms of your ARM loan. An ARM payment increase could stretch your budget thin, especially if your income has dropped or you’ve taken on other debt.

The Bankrate promise

The following table compares ARM rates to rates on other types of loans. The main risk with an ARM is that the rate will increase along with your monthly payments. The lender repeats the steps to adjust the interest rate and calculate the monthly payment every six months. A payment-option ARM, however, could result in negative amortization, meaning the balance of your loan increases because you aren’t paying enough to cover interest. If the balance rises too much, your lender might recast the loan and require you to make much larger, and potentially unaffordable, payments. The easiest way to shop for an ARM loan is to choose one with a start rate period that comes close to the time in which you expect to own the home or have the loan.

ARM adjustments in action

If you’re buying your forever home, think carefully about whether an ARM is right for you. But at the conclusion of the initial fixed-rate period, ARM rates begin to adjust until the loan is refinanced or paid in full. These rate adjustments follow a set schedule, with most ARM rates adjusting once per year.

Introduction to 3/1 ARM Mortgages

• For instance, if the SOFR rate is 2.0% and your margin is 2.5%, your ARM interest rate would be 4.5 percent.
• It’s important to know whether the loans you are considering have a higher initial adjustment cap.
• There are interest rate caps that limit how high interest rates can climb each year as well as ones that prevent interest rates from rising too much over the course of the entire loan term.
• With this type of mortgage, the actual indexed rate is fixed for the first three years of the loan, and then adjusts every year thereafter, a sort of hybrid between a fixed rate and an adjustable rate.
• That’s the biggest drawback of having an adjustable-rate mortgage.

The most common initial fixed-rate periods are three, five, seven and 10 years. Occasionally the adjustment period is only six months, which means after the initial rate ends, your rate could change every six months. The best way to get an idea of how an ARM can adjust is to follow the life of an ARM.

Can I refinance an ARM to a fixed-rate mortgage?

Your “margin” is the amount that’s added to the index rate to determine your actual rate. For instance, if the SOFR rate is 2.0% and your margin is 2.5%, your ARM interest rate would be 4.5 percent. At each rate adjustment, the lender will add your margin to your index rate to get your new mortgage rate.

• The margin acts as the floor, meaning the interest rate can never be lower than 3%, no matter how much the index rate decreases.
• A loan tied to a lagging index, such as COFI, is more desirable when rates are rising, since the index rate will lag behind other indicators.
• That way, they never have to deal with the risk of expensive rate adjustments and can enjoy stable payments over the life of the loan.
• Once that interest-only period ends, the borrower starts making full principal and interest payments.
• Because rates and monthly payments will increase after the fixed-rate period, 3-year ARMs are best for homeowners who plan to either sell or refinance their home within the first three years.
• If you have a fixed-rate mortgage, such as a 30-year fixed-rate home loan, your interest rate and mortgage payment will always remain the same.
• In contrast to a 3/1 ARM, a fixed-rate mortgage keeps the same interest rate for the life of the loan.
• A fixed-rate mortgage (FRM) has a rate that stays the same over the life of the loan.

How does a 3-year ARM loan work?

A 5/1 ARM, for example, has a fixed rate for five years, while a 3/6 ARM has a fixed rate for three. After that fixed-rate period, your lender will adjust your interest rate on a scheduled basis for the remainder of your 30-year loan term. With an interest-only loan you are paying best 3 year fixed rate mortgage only the interest for the initial 3 year period. Your payment is smaller for the initial period, but you aren’t paying back any principle. With some I-O mortgages the interest rate is adjusting during the initial I-O period, which gives a potential for negative amortization.

Can you refinance an ARM to a fixed-rate loan?

Yes, you can refinance your ARM to a fixed-rate loan as long as you qualify for the new mortgage. Yes, you can refinance an ARM just as you can any other mortgage loan. ARM requirements are similar to the minimum mortgage requirements for fixed-rate loans, but with a few significant differences. Especially if you expect interest rates to drop in the next three years, you may want to refinance with a conventional fixed-rate loan.

• In addition, the intro rate on a 7/1 ARM will be higher than on a 5/1 ARM because you get to hold onto the fixed rate for a longer time.
• Your payments may fluctuate every 6 months based on the current loan balance, new interest rate, and remaining loan term.
• The 5/1 ARM is virtually identical to the 7/1 ARM, except that the start rate will adjust after the first five years, rather than seven years.
• When the initial fixed-rate period ends, the adjustable-rate repayment period begins.
• These adjustments can lead to fluctuations in monthly mortgage payments, making it crucial for borrowers to comprehend the workings of ARM rates.

Further variations include FHA ARMs and VA ARMs, which are basically the government-backed versions of a conventional ARM, with their own set of qualifications. These are ARMs that allow you to convert your balance to a fixed rate, usually for a fee. In general, each type of loan has a different repayment and risk profile. The following graph is for a 5/1 ARM, but it does a good job of showing how payments can change over time.

1 vs 10/1 ARM rates

The ARM’s rate can then rise, fall or stay the same, depending on the movements of the broader market. A 3-year adjustable-rate mortgage functions a lot like any other ARM. The main differentiator with these loans is the length of the introductory period, during which the interest rate stays fixed.

In addition, those with a mortgage worth more than $750,000 cannot claim the deduction. If your margin is 2 percentage points and the SOFR is 0.15%, then your interest rate would be 2.15%.

Generally, the longer the I-O period, the higher the monthly payments will be after the I-O period ends. These loans are generally priced more attractively initially, because there is more potential profit for the lender. Interest rates are unpredictable, though in recent decades they’ve tended to trend up and down over multi-year cycles.

These caps limit the amount by which rates and payments can change. This can help you understand what your ARM would look like if rates were to spike and stay high. But keep in mind that this scenario is unlikely and you probably won’t pay the highest possible rate over your loan term. In addition, many borrowers move or refinance before the ARM fixed-rate period is up and never have to pay the higher payments that come with a fully-indexed rate. The 5/1 ARM will offer a fixed interest rate for the first five years of the loan term, while the 3/1 has a fixed rate for only the first three years. Once these teaser rates expire, the ARM will reset and be subject to interest rate adjustments for the remaining 25 or 27 years of the 30-year mortgage.

What’s the 3-year ARM rate?

Instead of refinancing from an adjustable-rate mortgage to a fixed-rate, they’ll refinance to an ARM, such as a 3/1 ARM. It might be a good move for short-term lower interest rates if you plan on moving in a few years. But if you’re refinancing and you want to stay in your house for the remainder of your loan term, getting a 3/1 ARM might not make sense. It’s important to run the numbers to see both the costs and the potential savings of either option. An adjustable-rate mortgage (ARM) is a type of mortgage where the interest rate can change at regular intervals following an initial fixed period. With a 3/1 ARM, the initial interest rate remains fixed for three years.
