Fixed-Rate vs. Adjustable-Rate Mortgages: What’s the Difference?

Choosing a mortgage involves understanding how your interest rate can affect your monthly payments and overall loan costs. Two common types of mortgages are fixed-rate mortgages and adjustable-rate mortgages (ARMs).

Understanding the difference between these options can help you better evaluate which type of mortgage may fit your financial situation and homeownership plans.

What Is a Fixed-Rate Mortgage?

A fixed-rate mortgage has an interest rate that generally remains the same throughout the agreed loan term.

Because the interest rate does not change, the principal and interest portion of your monthly mortgage payment generally stays consistent.

Key Features of a Fixed-Rate Mortgage

  • Interest rate remains fixed
  • Predictable principal and interest payments
  • Easier long-term budgeting
  • Protection from increases in market interest rates
  • Commonly available with different loan terms

A fixed-rate mortgage may be attractive to borrowers who prefer predictable payments and want greater certainty when planning their finances.

What Is an Adjustable-Rate Mortgage?

An adjustable-rate mortgage, commonly called an ARM, has an interest rate that can change after an initial fixed-rate period.

The rate may adjust periodically based on the terms of the mortgage and the applicable market index and margin.

Key Features of an Adjustable-Rate Mortgage

  • Initial interest rate may be fixed
  • Rate can change after the initial period
  • Monthly payments may increase or decrease
  • Loan terms determine when adjustments can occur
  • Future payments may be less predictable

An adjustable-rate mortgage may be considered by borrowers who understand the possibility of future rate changes and want to evaluate different initial-rate options.

Which Mortgage Is Right for You?

There is no single mortgage option that is right for every borrower. Your choice may depend on factors such as your financial situation, how long you expect to own the home, your comfort with changing payments, and the specific terms of the mortgage.

Before choosing a mortgage, consider both the initial payment and how your payments could change over time.

Questions to Consider

When comparing mortgage options, you may want to consider:

  • How long do I expect to own the home?
  • How important are predictable monthly payments?
  • Could I manage a higher payment in the future?
  • What are the interest-rate terms?
  • What fees and costs are associated with the loan?
  • What could happen if interest rates change?

Understanding these factors can make it easier to compare mortgage options and ask informed questions before making a decision.

Final Thoughts

Fixed-rate and adjustable-rate mortgages work differently, particularly when it comes to how interest rates and monthly payments can change over time.

Learning how each mortgage type works can help you better understand your financing options and prepare for the costs of homeownership.
