How an Adjustable-Rate Mortgage (ARM) Could Save You Thousands

An adjustable-rate mortgage (ARM) can be a powerful way to save money when interest rates are stable or falling. Unlike a fixed-rate mortgage, an ARM starts with a lower introductory rate, helping you build equity faster or reduce your monthly payment during the early years.

✅ How an Adjustable-Rate Mortgage Works

With an ARM, your interest rate remains fixed for an initial period—commonly 5, 7, or 10 years—before adjusting periodically based on a financial index, such as the Secured Overnight Financing Rate (SOFR).

  • Introductory rate: Lower than fixed-rate mortgages for the first term.
  • Adjustment period: After the intro phase, rates reset annually or semiannually.
  • Rate caps: Limits ensure your interest rate can only rise by a certain amount per period and overall.

Homeowners who plan to sell, refinance, or relocate within the fixed period often benefit the most from ARMs.

💡 When an ARM Makes Financial Sense

An ARM can be an excellent option when interest rates are stable or expected to decline, or if you plan to move or refinance before the fixed period ends. Here’s when an ARM might help you save thousands:

  • You plan to own the property for less than 10 years.
  • You’re comfortable with potential rate changes after the initial period.
  • You intend to refinance if rates drop further.
  • You want the lowest initial payment possible to free up cash flow.

Compare an ARM with a fixed-rate mortgage to understand the trade-offs between short-term savings and long-term stability.

📊 Potential Savings with an ARM

Because the starting rate is lower, ARMs often save homeowners thousands in interest payments during the first several years of ownership. That money can be used toward paying down principal, investing, or saving for future goals.

  • Lower initial monthly payments than a 30-year fixed mortgage
  • Reduced total interest in early years
  • Flexibility to refinance before rate adjustments
  • Ideal for buyers expecting income growth or relocation

However, if rates rise sharply, payments can increase. Always factor in possible rate adjustments when budgeting.
