Understand How Adjustable-Rate Mortgages Impact Your Monthly Payments
Choosing the right mortgage is one of the most critical decisions you’ll make when buying a home or refinancing. Our Adjustable-Rate Mortgage (ARM) Calculator is here to help you navigate your options, understand potential costs, and determine if an ARM is the right fit for your financial goals.
What Is an Adjustable-Rate Mortgage (ARM)?
An Adjustable-Rate Mortgage (ARM) is a home loan with an interest rate that changes over time. Unlike fixed-rate mortgages, where your interest rate stays the same throughout the loan term, ARMs adjust periodically based on a benchmark index, such as the Secured Overnight Financing Rate (SOFR).
ARMs are a flexible option for many homebuyers, especially those planning to stay in their homes for a shorter period or who anticipate lower interest rates in the future.
How Does an ARM Work?
ARMs consist of several key components that define how they function:
- Initial Fixed-Rate Period:
During the initial period, which typically lasts 5, 7, or 10 years i.e. 5/1 ARM, your interest rate remains fixed. This phase offers predictability and often lower rates compared to fixed-rate mortgages. - Adjustment Periods:
After the fixed period, the interest rate adjusts periodically, usually every 6 or 12 months. Adjustments depend on the benchmark index and a set margin determined by the lender. - Interest Rate Caps:
ARMs include safeguards to limit how much your rate can increase. These caps are defined as:
- Initial Cap: The maximum adjustment after the fixed-rate period ends.
- Periodic Cap: The limit on rate increases for each adjustment.
- Lifetime Cap: The maximum amount your rate can increase over the loan’s life.
- Payment Caps:
Some ARMs feature payment caps, which limit how much your monthly payment can increase during each adjustment period, offering additional protection.
Benefits of Adjustable-Rate Mortgages
ARMs offer several advantages that make them an attractive option for many borrowers:
- Lower Initial Interest Rates:
ARMs typically have lower starting rates than fixed-rate mortgages, resulting in smaller initial monthly payments. - Savings for Short-Term Homeowners:
If you plan to sell or refinance before the adjustment period, you can maximize savings during the low-rate fixed period. - Potential for Long-Term Savings:
If market interest rates remain stable or decline, you could benefit from lower monthly payments compared to a fixed-rate mortgage.
Potential Drawbacks of ARMs
While ARMs have advantages, it’s essential to consider the risks:
- Rising Interest Rates:
Your monthly payments could increase significantly if interest rates rise during adjustment periods. - Interest Rate Risk:
The unpredictability of future rates means you may face budget challenges if rates increase substantially.

FAQs About Adjustable-Rate Mortgages
Q: What does the “5/1” in a 5/1 ARM mean?
A: The “5” represents the initial fixed-rate period (5 years), and the “1” indicates that the interest rate will adjust annually after that period.
Q: Are ARMs riskier than fixed-rate mortgages?
A: ARMs carry more uncertainty due to rate adjustments, but interest rate caps and payment caps help mitigate risk. They are best suited for borrowers who can manage potential rate changes.
Q: Can I refinance an ARM later?
A: Yes, refinancing is an option if you want to switch to a fixed-rate mortgage or lock in a more favorable rate before an adjustment.
Q: What happens when the fixed-rate period ends?
A: Once the fixed-rate period ends, your loan enters the adjustment phase. The interest rate is recalculated based on the index (e.g., SOFR) and a set margin, and your monthly payment is adjusted accordingly.
Q: What is the difference between a 5/1 ARM and a 7/1 ARM?
A: The difference lies in the fixed-rate period. A 5/1 ARM has a fixed rate for the first 5 years, while a 7/1 ARM has a fixed rate for 7 years. After that, both adjust annually.
Q: Can I lock in a new rate during the adjustment period?
A: No, the rate during the adjustment period is determined by the index and margin specified in your loan agreement. However, you can refinance to a fixed-rate loan to lock in a new rate.
Q: Are there penalties for paying off an ARM early?
A: Some ARMs include prepayment penalties during the fixed-rate period. Check your loan agreement or consult your lender to understand if this applies to your loan.
Q: How often can my interest rate adjust?
A: This depends on your loan terms. Most ARMs adjust annually after the fixed-rate period, but some may adjust every 6 months or another specified interval.
Q: What are lifetime caps, and how do they protect me?
A: Lifetime caps limit how much your interest rate can increase over the entire term of the loan, providing a safeguard against excessive rate hikes.
Q: How do I know if an ARM is right for me?
A: ARMs are ideal for buyers who:
- Plan to sell or refinance before the fixed-rate period ends.
- Want lower initial payments.
- Are comfortable with potential rate adjustments.
Q: What is a margin, and how does it affect my rate?
A: A margin is a fixed percentage set by your lender that is added to the index rate to determine your adjustable interest rate. It remains constant throughout the loan term.
Q: Can my monthly payment decrease with an ARM?
A: Yes, if the index rate decreases during the adjustment period, your monthly payment may also decrease. However, this depends on market conditions and your loan terms.
Q: Are ARMs a good option for first-time homebuyers?
A: They can be, especially if first-time buyers want lower initial payments or plan to upgrade to a larger home within a few years. However, ARMs require careful financial planning to handle potential rate changes.
Q: How does an ARM compare to a fixed-rate mortgage?
A: Fixed-rate mortgages offer consistent payments but usually have higher initial rates. ARMs start with lower rates, which can save money initially but may increase later based on market conditions.
Q: What happens if I can’t afford payments after a rate adjustment?
A: If your budget becomes strained, you can explore options like refinancing to a fixed-rate mortgage, modifying your loan, or selling the property. It’s essential to plan ahead for potential adjustments.
Q: What are hybrid ARMs?
A: Hybrid ARMs combine features of both fixed and adjustable-rate mortgages. For example, a 7/1 ARM has a 7-year fixed-rate period followed by annual adjustments.
Q: Can I switch from an ARM to a fixed-rate mortgage?
A: Yes, you can refinance your ARM into a fixed-rate mortgage if it makes financial sense and you meet the lender’s requirements.
Q: Are ARMs suitable for investment properties?
A: ARMs can be a good choice for investment properties, especially if you plan to sell or refinance before the fixed-rate period ends, as they often offer lower initial payments.
Q: What factors influence my adjustable interest rate?
A: Your adjustable rate depends on the benchmark index i.e. SOFR, the lender’s margin, and any caps outlined in your loan agreement.
Q: How do lenders determine the index used for adjustments?
A: Lenders specify the index in your loan agreement. Common indices include the Secured Overnight Financing Rate (SOFR) and the 1-Year Treasury Constant Maturity Index (CMT).
Q: Are ARMs riskier than fixed-rate mortgages?
A: ARMs carry more variability in payments due to rate adjustments, but interest rate caps and payment caps mitigate some of the risks. They are best for borrowers comfortable with potential changes.
Q: How do I prepare for potential rate adjustments?
A: Build a financial cushion to handle higher payments, and regularly monitor market trends to anticipate potential changes in your interest rate.
Q: Can an ARM help me qualify for a larger loan?
A: Yes, the lower initial payments of an ARM may allow you to qualify for a larger loan compared to a fixed-rate mortgage.
